Hello, I have a scatter plot.
I utilize callback functions on hover_data. When the cursor moves to a specific data point, we change its color. When the cursor leaves the data point, the color of the point should be resumed.
hover_data can give me the index of the data point, so that I can change the color.
However, how to distinguish the mouse moving in and out behavior?
I recorded the index of the points, e.g., index of the current hover, and index of the previous hover. It works. But when I move the mouse quickly, the color may not be resumed.
