matlab pin annotation to axes

If you ever find any interesting items, please drop me an email, or post a comment below. Sign in to answer this question. A few things are happening here. TEXT positions text in relation to axes. pos = hgconvertunits(hFig, get(Axes, 'position'), get(Axes, 'units'), 'Normalized', hFig); The solution. Another problem is to pin the annotation to the axes data. % Create a text-arrow annotation with the requested string at the requested position hAnnotation = handle(annotation('textarrow', annotationX, annotationY, ... the x-axis at particular x-axis-values in my plots. Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. tAnnotation.pinAtAffordance(1); One problem with using annotation seems to be that one is required to give the coordinates in normalised units, which, in turn, does not allow me to add objects like lines/arrows/textboxes. Speeding-up builtin Matlab functions – part 3, Matlab toolstrip – part 9 (popup figures), Matlab toolstrip – part 7 (selection controls), Matlab toolstrip – part 6 (complex controls), Matlab toolstrip – part 4 (control customization), Reverting axes controls in figure toolbar, Matlab toolstrip – part 3 (basic customization), Matlab toolstrip – part 2 (ToolGroup App), Medium risk of breaking in future versions, Matthias Brenneis (101 days 22 hours ago). % Pin the annotation object to the required axes position A lot of things broke in R2014b due to the replacement of the graphics engine in this release (HG2). Control the label for the new data series by setting the DisplayName property as a name-value pair during creation. If you do not want the axes outline to appear, you can turn it off using this command: axis off If you have an area, bar, or stem plot that has a baseline and want to turn off the baseline, set the Visible property of the Baseline object to 'off', for example: • If you omit the increment, MATLAB automatically increments by 1. Otherwise, the annotation function will shout. The only difference in use with the annotation function is that you can provide the axes handle. The resulting axes object is the current axes, so the next plotting command can plot into it. HeadLineStyle: '-' I'd like to put a 'dd-mmm-yyyy' formatted starting date as an annotation in the bottom left corner of the figure. If you do not specify a label, then the legend uses a label of the form 'dataN'.. If you specify the type as 'line', 'arrow', 'doublearrow', or 'textarrow', then the second input is the starting and ending x positions of the annotation. The following Matlab project contains the source code and Matlab examples used for annotation pinned to axes. % ^^^^ We could have used some other Y data value for this We then use the undocumented hgconvertunits function to convert from pixel units into normalized figure units: % Convert axes data position to figure normalized position There’s probably a new way to do the same functionality in HG2, but I do not have the time or inclination to dive into this at the moment. if xValue < xlim(1) || xValue > xlim(2) Then set the z-axis limits for the bottom plot by specifying ax2 as the first input argument to zlim. If the axes do not include two y -axes, then this command adds a second y -axis. If you specify the text as a categorical array, MATLAB ® uses the values in the array, not the categories.. (For example, when you need many labels on a figure). Many Matlab users are aware of Matlab’s annotation functionality, which enables us to assign graphic elements such as arrows, lines, ellipses and text labels to Matlab figures. Learn more about pin Here is an example-plot: I would like to draw vertical lines or arrows downwards from the x-axis exactly where the white lines are in the graph (basically 'extending' the white lines below the x-axis). hAnnotation.TextEdgeColor = [.8,.8,.8]; Instead, they clip at the boundaries. MATLAB: How to pin annotations (or text) to a graph below the x-axis. The obvious first place to start debugging this issue is to go to the annotation handle’s context-menu (accessible via the UIContextMenu property), drill down to the “Pin” menu item and take a look at its callback. As an example tiledlayout(2,2); IB-Matlab: InteractiveBrokers-Matlab connector, EODML: EODHistoricalData-Matlab connector, % Note: we need 2 X values: one for the annotation's head, another for the tail, % Note: we need 2 Y values: one for the annotation's head, another for the tail. % Note: we use a static Y position here, spanning the center of the axes. This is an internal method of the scribepin UDD class, so in order to use it we need to create a dummy scribepin object. PinExists: [0 0] Sign in to comment. My current solution is to use text instead of annotation (as shown in graph) because it allows me to add the labels below the x-axis (see part of my script below). set(0,'showhiddenhandles','on') % look for all axes in the figure of choice: h_all_axes = findall(gcf,'type','axes'); % get the 'annotation layer' axes handle: h_anno_axes = double(find(handle(h_all_axes),'-class','graph2d.annotationlayer')); delete(h_anno_axes); set(0,'showhiddenhandles','off'); annotationPos = [0.55 0.58 0.6 0.3]; htxtbox = … For example, using the graph from the previous example, add an x- and y-axis labels. I'm trying to implement a modified version of datetick2 from the MATLAB FEX. For example, this code creates a surface plot and a scatter plot, and then calls the alpha function to vary the transparency along the x -dimension. text (x,y,z,txt) positions the text in 3-D coordinates. @ 2014b this dose not works. This places a text box with horizontal offset of 50% of the Figure's width, and vertical offset of 20% of the Figure's height. example. Since plot axes are always obscured by uicontrols, so too is the annotation layer. figNormPos = hgconvertunits(hFig,[figPixelPos(1,1:2),diff(figPixelPos)],'pixels','norm',hFig); MATLAB automatically creates an axes, if one does not already exist, when you issue a command that creates a graph. % YLim may have changed, so recalculate y end For example, text([0 1],[0 1],'my text'). Note that this process will output vectors describing a ray in 3D coordinates, and that all points on this ray are projected to the same pixel locations. Masochistic readers may find many hours of pleasure sifting through the scribe code functionality for interesting nuggets such as the one above. In fact, they are located in a separate axes layer. hAnnotation = handle([]); Call the nexttile function to create the axes objects ax1 and ax2.Plot data into each axes. The annotations may appear to be connected to the plot axes, but this is merely a visual illusion. A Matlab text-arrow annotation (unpinned). So assuming the aspect ratios of the axes and figures aren't always in sync with each other, you'd have to add a resize listener to redo the calculations on resize. Keep in mind that my post was written back in 2012, many Matlab releases ago, and before HG2 was released (in R2014b), so if you're using a recent Matlab release this functionality may quite possibly fail. Toggle Main Navigation. Call the tiledlayout function to create a 2-by-1 tiled chart layout. Previous versions of MATLAB ® allow annotations to extend into (or out of) the boundaries. Annotation pinned to axes in matlab . % Note: we use a static Y position here, spanning the center of the axes. HTML tags such as or are accepted. Try to recreate my example on a new empty figure and then try to see what is different in your existing code/figure. To add text to one point, specify x and y as scalars. hThis = handle(har); The limits of the axes do not matter, whan you use 'normalized' posiotions. You can use the attached function named "axxy2figxy.m" to transform coordinates from data (axes) space to figure space. That positioning is done before the box is trimmed to the text, which leaves the text floating pretty far from the desired location. Pinning annotations to graphs Limitations of Matlab annotations. Finally, the annotation objects are only displayed on top of plot axes – they are obscured by any GUI uicontrols that may happen to be present in the figure. Modify Figures in Live Scripts. PixelBounds: [0 0 0 0] xlim = get(hAxes,'XLim'); HeadFaceAlpha: 1 y = yLim(1) + 0*sum(yLim) + [0.1,0]*diff(ylim); % TODO: handle reverse, log Y axes It may not be quite the result you want, but it’s likely the only option you have. localPinObject(har);%matlabroottoolboxmatlabscribe@scribe@scribeobject1DcreatePinContextMenu.mfunction localPinObject Learn more about annotation, subplot, southeast, text box in plot, print value in subplot MATLAB Notice that all this relies on pure Matlab code (i.e., no mention of the dreaded J-word…). My hunch is that either you have a bug in your code, or perhaps your figure window has some element which causes the annotation scribe layer to behave differently. % Prepare the annotation's Y position For example, create two plots and assign the axes objects to the variables ax1 and ax2. % never mind - ignore (no error) end. Matlab’s implementation of annotation is an attempt to replicate Java’s standard glass-pane mechanism. I have been reading through Yair Altman's undocumented matlab site on this topic as well as checked other answers here and in other forums but I cannot quite work out how to adjust these suggestions for my particular problem. Change the axes font size and x-axis color for … Adding titles, axis labels, and annotations. In fact, they have more undocumented properties than documented ones. HelpTopicKey: '' IncludeRenderer: 'on' To display different text at each location, use a cell array. Reload the page to see its updated state. Editing: 'off' Unfortunately, annotation has several major deficiencies, that are in fact related: Labels and Annotations Add titles, axis labels, informative text, and other graph annotations; Axes Appearance Modify axis limits and tick values, add grid lines, combine multiple plots; Colormaps View and modify colormap, control color scaling, add colorbar; 3-D Scene Control Add light, set object transparency, control camera view; Featured Examples These include arrow, doublearrow, textarrow, and ellipse. ANNOTATION can put on figure not only text, but lines, shapes, arrows, etc. In R2020a and earlier releases, the alphadata, facealpha, and alphadatamapping arguments have no effect on Scatter objects in the axes. I don't need the additional annotations, but I would like to remove the ticks on the axes. Unfortunately, this does not work well, because the context-menu is empty when the annotation is first created. annotationY = figNormPos([2,2]) + figNormPos(4)*[1,0]; Finally, we use the annotation handle’s pinAtAffordance() method and set the Pin.DataPosition property to the requested X,Y values (we need to do both of these, otherwise the annotation will jump around when we zoom/pan): % Ensure that the annotation is within the axes bounds, then display it I also tried it for textboxes, which are located on the doublearrows. Call the tiledlayout function to create a 2-by-1 tiled chart layout. You can modify figures interactively in the Live Editor. hAnnotation.pinAtAffordance(2); TailLineStyle: '-' If you specify this property as a categorical array, MATLAB ® uses the values in the array, not the categories. The words default, factory, and remove are reserved words that do not appear in text when quoted as normal characters. I believe this is due to the complex implementation, having quite a few checks and re-calculations (e.g., back and forth between coordinate systems and units). I can't manage to get axes similar to the ones in this figure: I know I can remove the top and right lines like in this question, but I don't know how to get the arrows on the edges. Show Hide all comments. Unfortunately, the annotation handle does not provide a documented way to do this programmatically. A context-menu is only assigned to the annotation after the Edit Plot toolbar button and then the annotation object are clicked. To add an arrow or line annotation to a graph: Click on the Insert menu and choose the Arrow or Line option, or click the Arrow or Line buttons in the figure window toolbar.. MATLAB changes the cursor to a cross-hair style. Use single quotes around 'left' and 'right'. Select Pin Object from the Edit menu. Starting in R2014b, annotations cannot cross uipanel boundaries. Modifying the Text Arrow from the Context Menu YLimInclude: 'on' We can indeed pin the annotation to the graph, but this requires delicate manual interaction (click the Edit Plot toolbar icon, then right-click the relevant annotation end-point, then select “Pin to Axes” from context menu). Now label the axes and add a title. HeadColorMode: 'auto' FigureResize: 0 ColorProps: {5x1 cell} catch Starting in R2014b, annotations cannot cross uipanel boundaries. Through the handle returned by annotation we can customize the annotation’s appearance (for example, line width/style or text font properties). annotation; arrow figure line plot text arrow text box text; I would like to add vertical lines (or arrows) and text-labels below the x-axis at particular x-axis-values in my plots. Here is an example-plot: ... Another problem is to pin the annotation to the axes data. If you add or delete a data series from the axes, the legend updates accordingly. To display the same text at each location, specify txt as a character vector or string. This is based on a transparent hidden axes that spans the entire figure’s content area, on which the annotations are being drawn (also called the scribe layer). This is definitely somewhere else on this website and in the matlab documentation. y = yLim(1) + 0*sum(yLim) + [0.1,0]*diff(ylim); % TODO: handle reverse, log Y-axes TailColor: [0 0 0] So if we store the axes handles for each tile then we can plot new changes to existing tile by shifting to that axes handle using axes function. ans = This does, however, not work, since 0 and 1 refer to points in the whole figure (the window in which the plot appears) and not to the area of the plot itself. Afsize: 6 ANNOTATEAXES: Annotation object in axes data coordinate version 1.1.0.0 (10 KB) by Kesh Ikuma ANNOTATEAXES places a built-in annotation object and tie it to an axes the x-axis. figPixelPos = scribepin.topixels; Call the nexttile function to create the axes objects ax1 and ax2.Plot data into each of the axes. Is there any solution to this?? This results in unintelligible and misleading annotations. hAnnotation.pinAtAffordance(1); If you do not specify a label, then the legend uses a label of the form 'dataN'.. Note that it is ok to move the annotation outside the figure bounds later on (via panning/zooming) – it is only the initial annotation creation that must be within the figure bounds (i.e., between 0.0-1.0 in normalized X and Y units): % Prepare the annotation's X position edit: Now that you have shown what you are doing. 90 s/180 s = 0.5 --> x-position in normalized coordinates). Often, we are interested in an annotation on a plot axes that does NOT span the... Debugging the problem. It's inconsistent to have provided text(X,Y,str) using X and Y in data coordinates and not annotation … I really hope that a complete refactoring of scribe and the related uimodes will be one of the benefits that we will see in HG2. Next, we convert our plot data units, in order to get the annotation’s requested position in the expected figure units. I have been reading through Yair Altman's undocumented matlab site on this topic as well as checked other answers here and in other forums but I cannot quite work out how to adjust these suggestions for my particular problem. To display an annotation within a specific figure, uipanel, or uitab, use the container input argument. Here is the list for a simple text-arrow annotation, such as the one that we used above: >> getundoc(hAnnotation) From my own experience if you are running version earlier than R2014b, then positioning annotation does not work very good, but from R2014b upwards, once you properly set the Parent property, positioning is not problem. How can I do that? For a custom color, specify an RGB triplet or a hexadecimal color code. @Andy – I don’t see why a textbox annotation cannot be used. subplot(m,n,p) divides the current figure into an m-by-n grid and creates axes in the position specified by p.MATLAB ® numbers subplot positions by row. I needed to be able to create annotations to plots that would be pinned to the axes … ALimInclude: 'on' To display any of these words individually, precede them with a backslash, such as '\default' or '\remove'. When the coordinate conversion is done by the call to hgconvertunits, something is wrong with x(2). Text for Multiple Data Points. If you’d like me to investigate this specific issue for you, email me. hThis.Pin(1).updateTarget; With annotations, textbox positions are always specified in terms of normalized figure size. 90 s/180 s = 0.5 --> x-position in normalized coordinates). The size of the box is 10% of Figure's height by 10% of Figure's width: ScribeContextMenu: [9x1 uimenu] EraseMode: 'normal' You may receive emails, depending on your. Behavior: [1x1 struct] Learn more about annotation, text, figure, plot, text box, line, arrow, text arrow isn't shown, depending on the range of times in the plot. hFig = ancestor(Axes,'Figure'); Axes properties related to the y-axis have two values.However, MATLAB ® gives access only the value for the active side. hThis.Pin(2).DataPosition = [X2 Y2 Z2]; TailHandle: [1x1 line] Matlab has a corresponding built-in function, annotation, that enables creation of annotation objects. I’m using MATLAB 2012a, and unfortunately it doesn’t work here. ShapeType: 'textarrow' FaceColorDescription: 'Head Color' The handle is visible if the HandleVisibility property of the object is set to 'on'.The next plot added to the axes uses the first color and line style based on the ColorOrder and LineStyleOrder properties of the axes.
