I created a dash app with a graph component and option component (radio button or dropdown). When I play the animation and switch the plot type (line to scatter for example) the plots get into each other and doesn’t perform correctly. I also noticed that the same appears in the example provided in the second Intro to animations in Python (plotly.com). The example’s timeline is short so this may not be clear from regular usage. If the same is reproduced for larger data with longer animation time this can be clearer.
