selectedData in pie chart

Dash Python
1

Is there an option to use selectedData in the pie chart?

let’s say I have a pie chart that shows 3 categories and I want to filter other charts on my graph when clicking on one of the categories on the chat. I can achieve this with clickData but, how can I grey out the other categories on the chart? it doesn’t do it automatically like on the bar chart. plus, let’s say I want to have two categories to filter by, I can’t do it with clickData alone easily.

(I can by creating a div and saving and removing the “points” and filtering from that div data which is a big work around.)

Hello @Matan,

I actually requested this earlier this fall.

What I do currently is to use the clickData, and then have an event listener added to the class slice which acts as a toggle for either a color change or a transform, whichever you prefer.

Hmm I see, this seems like a really important feature, hopefully, they will add it soon.
Mind giving me the link to your git request I will give it a thumbs up.

I didn’t do a request, just verbally through @adamschroeder. XD

If you’ll do a request, I’ll thumbs up you. Haha.

Here we go!

Guys if you read this and you want this feature, please! go and upvote the feature request on GitHub, it will help a ton!

For those who can’t wait for the feature, I wrote in the feature problem section a way you can filter the pie chart without the feature it’s a bit of work but the only way I found out is to implement the required feature.

if anyone finds a better way please let me know!
