Can you add contour map #13909

Open Alexander-txj opened 3 years ago

Alexander-txj commented 3 years ago

What problem does this feature solve?

Recently, I am doing industrial drawings, and I need to realize the contour map of the polar coordinate system. Finally, only d3-contour can be used. I think the application of contour map is still very extensive and can be put in echarts.

What does the proposed API look like?

You can refer to Python Matplotlib

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 you have posted enough image to demo your request. 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.

If you are interested in the project, you may also subscribe our mailing list.

Have a nice day! 🍵

like this image image image The last is the polar coordinate contour map that I realized with d3 image

Perhaps, the contour chart can be an extension of ECharts, just like echarts-wordcloud and echarts-liquidfill.

I am available for help in implementing such a feature. @Ovilia please, let me know.

nvelden commented 2 years ago

Any updates on this? Would love to have this feature and as mentioned above it has loads of use cases.

Sorry for late reply. What kind of help do you need?

Ovilia commented 2 years ago

You may consider implementing with custom series.

Any updates on the implementation of Contour plots in ECharts?

sunpcm commented 1 year ago

Do we have any updates or workaround for Contour plots?

helgasoft commented 1 year ago

@Ovilia mentioned custom series.
Contour plots are doable with custom.polygon, see #18344.

Hi all, anyone is working on this request?

helgasoft commented 5 months ago

As @plainheart said - good candidate for an extension, but not for an integral part of ECharts. There are two separate questions here: 1) how to extract contours and 2) how to display contours. Extracting contours from XYZ data is data preparation, done by specialized libraries. Displaying contours is already feasible in ECharts with series type 'line' or 'custom-polygon' (for filled areas). Below are two examples displayed with ECharts. image

I like to use scatter with contour, particularly for data science visualization. Supporting it for inclusion in EChart 6.0
