How to plot polar charts in Dash?

[deejep]

Hi,
How to plot polar charts in Dash ? Are there any examples available ?
Thank you.

Whatever you can do with plotly.js, you can do it with Dash. So, pick your poison:

Polar Charts

Polar Charts

Polar Charts

etc.

Note that the plotly.js polar charts a little bit under-developed. See https://github.com/plotly/plotly.js/milestone/2.

We’re looking for a company to help sponsor this work. If polar charts are instrumental to your company’s app development, please reach out: https://plotly.typeform.com/to/mH1Cpb

Update! A company has sponsored the development of a polar chart rewrite . Expect a new and enhanced set of polar charts in early 2018 . We are tracking this feature in this branch: https://github.com/plotly/plotly.js/tree/polar (no PR yet).

If your company or organization needs enterprise-level support or custom features developed, please reach out to our advanced development team: https://plot.ly/products/consulting-and-oem/

This is hugely exciting!

@chriddyp Has the URL moved to a new branch? 404 on https://github.com/plotly/plotly.js/tree/polar

Has the URL moved to a new branch? 404 on https://github.com/plotly/plotly.js/tree/polar

It was merged earlier this week See https://github.com/plotly/plotly.js/pull/2200 and Regl-based scattergl and scatterpolargl traces by etpinard · Pull Request #2258 · plotly/plotly.js · GitHub. The plotly.js team printed a release last night (Releases · plotly/plotly.js · GitHub) which I’ll move into the dash core components library sometime today. I’ll keep this thread posted with progress.

PR to upgrade dash-core-components: https://github.com/plotly/dash-core-components/pull/149. The new polar and scattergl chart types will be available in version 0.18.0, upgrade with:

pip install dash-core-components==0.18.0

Enjoy!

Amazing! Can’t wait. Will the new Polar be on plot.ly at some point too?

@will

Will the new Polar be on plot.ly at some point too?

Yes it will be. We have to go through quite a bit more testing and QA before that happens.

I often find pointers to plotly when I’m searching for ways to use dash, and these are not too helpful. As chriddyp mentions above (2 years ago), dash-core-components is now very much up to date with polar plots and I found a great example in https://github.com/plotly/dash-sample-apps/. The examples here are extremely helpful - IMO more so than documentation.
Specifically look at apps/dash-wind-streaming for live wind plots with wind direction and speed in a polar plot.

Thanks for the tip.
But which one is a radar plot? I could find an example there.

@ruslaniv Are you looking for the documentation on the radar plot? https://plotly.com/python/radar-chart/

For some reason it’s totally not working for me:

Basic Radar Chart with Dash

Hi! I’ve been trying to follow up this tutorial here: It does not seem very difficult, but I’m getting completely different results. I have this: r = [28, 81, 4, 3] theta = [19498, 9144, 6245, 799] r is number of visits theta is ID’s So I build my chart like this in a callback function: data = [go.Scatterpolar(r=r, theta=theta, fill='toself')] layout = go.Layout(polar=dict(radialaxis=dict(visible=True),), showlegend=True) return {'data': data,'layout': layout} and I get nothing similar…

Looks like the problem is now fixed in that linked thread
