If you specify this property as a function handle or cell array, you can access the object that is being created using the first argument of the callback function. Setting the CreateFcn property on an existing component has no effect. If you do not specify the CreateFcn property, then MATLAB executes a default creation function. MATLAB initializes all property values before executing the CreateFcn callback. This property specifies a callback function to execute when MATLAB creates the object. MATLAB evaluates this expression in the base workspace.įor more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects.

If you need to switch between different shape-drawing or other dragmodes (panning, selecting, etc.), modebar buttons can be added in the config to select the dragmode. In MATLAB you can use patch instead of rectangle. You can create layout shapes programmatically, but you can also draw shapes manually by setting the dragmode to one of the shape-drawing modes: 'drawline', 'drawopenpath', 'drawclosedpath', 'drawcircle', or 'drawrect'. show ()ĭrawing shapes with a Mouse on Cartesian plots ¶ update_yaxes ( range =, zeroline = False, ) # Add shapes fig. update_xaxes ( range =, zeroline = False, ) fig.

Does MATLAB support transparency (so I can get nicer looking leaves) Yes.
Traces also support optional text, although there is a textual equivalent to shapes in text annotations.Traces cannot be positioned absolutely but can be positioned relative to date coordinates in any subplot type.Shapes can be positioned absolutely or relative to data coordinates in 2d cartesian subplots only.Traces can optionally support hover labels and can appear in legends.The differences between these two approaches are that: Note: there are special methods add_hline, add_vline, add_hrect and add_vrect for the common cases of wanting to draw horizontal or vertical lines or rectangles that are fixed to data coordinates in one axis and absolutely positioned in another. Standalone lines, ellipses and rectangles can be added to figures using fig.add_shape(), and they can be positioned absolutely within the figure, or they can be positioned relative to the axes of 2d cartesian subplots i.e.scatter, scatter3d, scattergeo etc) can be drawn with mode="lines" and optionally support a fill="self" attribute, and so can be used to draw open or closed shapes on figures.
