opened on Nov 20, 2019

It would be interesting to port to plotly.js some shape-drawing features which exist in dash-canvas at the moment (https://dash.plot.ly/canvas). In an existing figure, the user would have the possibility to

  • create new shapes such as rectangles, lines, freehand lines (paths), by selecting a specific type of drag mode in the modebar
  • modify these shapes (moving them, and if possible scaling them and rotating them). Deleting the last shape would be a plus.
  • retrieving the geometry of shapes would probably be done thanks to relayoutData events in Dash.

Also discussed:

  • having a new_shape_style attribute to set the style of shapes individually.
  • all the drag modes would not be in the modebar by default but could be added individually

                It would be interesting to port to plotly.js some shape-drawing features which exist in dash-canvas at the moment (https://dash.plot.ly/canvas). In an existing figure, the user would have the possibility to
                • create new shapes such as rectangles, lines, freehand lines (paths), by selecting a specific type of drag mode in the modebar
                • modify these shapes (moving them, and if possible scaling them and rotating them). Deleting the last shape would be a plus.
                • retrieving the geometry of shapes would probably be done thanks to relayoutData events in Dash.
                Also discussed:
                • having a new_shape_style attribute to set the style of shapes individually.
                • all the drag modes would not be in the modebar by default but could be added individually
