Do not display a point when its value is undefined in radar charts

[lovervoorde]

What problem does this feature solve?

NaN, undefined, null etc. are displayed as zero in radar charts, making it impossible to tell whether the value is actually zero or is missing.

I would like it if the point was skipped, and the two points on either side of it were joined with a straight line.

What does the proposed API look like?

series-radar.connectNulls: true series-radar.nullsToZero: false

Hi! We've received your issue and please be patient to get responded. 🎉 The average response time is expected to be within one day for weekdays.

In the meanwhile, please make sure that it contains a minimum reproducible demo and necessary images to illustrate. Otherwise, our committers will ask you to do so.

A minimum reproducible demo should contain as little data and components as possible but can still illustrate your problem. This is the best way for us to reproduce it and solve the problem faster.

You may also check out the API and chart option to get the answer.

If you don't get helped for a long time (over a week) or have an urgent question to ask, you may also send an email to dev@echarts.apache.org. Please attach the issue link if it's a technical question.

Here is a demo of how it could look. It is made using a line graph on polar axes, which might be a reasonable interim solution for anyone looking for this feature: https://codepen.io/lovervoorde/pen/zYZvQmv

Yes please folks. I also have the same issue of nulls being shown as zeros on Radar charts, and it would be great to have a fix. Thanks for the great library.

Same here. We have been looking for a solution and found this posting that describes exactly the problem.

Same here. Any updates on this case?
