I’m trying to make a histogram2d plot that updates dynamically using the Plotly.animate api. That is, I have some arrays of x and y data that I periodically add points to, and I then want to update a histogram2d plot of these data. For a scatter plot this works perfectly and I end up with a nice animation. But for some reason, for histogram2d this doesn’t work – the plot remains static.
I’ve set up a minimal non-working example here: https://codepen.io/jvkersch/pen/YxrVvw
Essentially, this creates a new plot, and then calls Plotly.animate in a requestAnimationFrame loop. Running the example shows that the data is updated, for some reason the plot doesn’t update.
Does anybody know why this wouldn’t work, or what I am doing wrong? Any help is appreciated!
With best wishes,
