My question is this, suppose I draw a square shape - how do I automatically draw a circle shape using the mouse information provided by the square shape?
Can someone please point to a location where I can learn to do this?
I’ve been able to do all the examples found in “Image Annotations” section, but I haven’t been able to figure out the code, and callback to automatically add an annotation based on user input.
Any help in doing this would be greatly appreciated!
you could trigger the click event and create the circular shape directly like this:
You could also extract the shape(s)information from the figure and extract the coordinates of the shape and use the dimensions to create your circular shape.
def get_current_shape(figure):
# extract shape information from figure
shapes = figure['layout'].get('shapes', [])
return shapes
def extract_shape_info(shape):
color = shape.get('line', {}).get('color', {})
dimensions = [shape.get(coordinate, {}) for coordinate in ['x0', 'y0', 'x1', 'y1']]
return color, dimensions
