This shape-drawing feature is particularly interesting for annotating graphs, in particular image traces or layout images. If you switch to a different dragmode such as pan or zoom, you will need to select the drawing tool in the modebar to go back to shape drawing. 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. 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.
