Colorbar does not update correctly when updating a dcc.Graph #702
Description
Activity
Here's the same thing as a codepen: https://codepen.io/alexcjohnson/pen/JjjwBKE?editors=0010
newplot@1 -> react@0 is different from newplot@0
So it's a plotly.js bug - I'm going to file it with plotly/plotly.js#4337, which describes a slightly different situation but I suspect the underlying cause is the same
Thanks @TedHaley!Oh actually it may be exactly the same thing...
It looks like this issue was closed in plotly/plotly.js#4337, so I'm assuming we can close here.
See the original community post https://community.plot.ly/t/render-colorbar-issues/31293 and the test repo https://github.com/TedHaley/bugs reproducing the issue. Basically, two datasets with different data ranges, when switching between the two the colorbar gets stuck at the same data range and therefore the colors are not what they should be. In the demo app, try switching from
plot 2toplot 1and fromblanktoplot 1. Don't know whether dcc is the right place for this or if I should open an issue also inplotly.js(but the two figures look good independently, it's just the update which does something weird).
