3 years ago 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.
If you are interested in the project, you may also subscribe to our mailing list.
Have a nice day! 🍵

Version
5.1.2
Reproduction link
https://codesandbox.io/s/echarts-geo-map-with-image-wfvvn?file=/src/index.js
Steps to reproduce
<image>tag where the href property is a url{ coordinateSystem: "geo" }What is expected?
Expect to see heatmap points rendered on top of the image in the svg similar to this:
What is actually happening?
The data points are being plotted correctly, but the
<image>is not being loaded.Our team is considering migrating to Echarts. We'd love to be able to plot the heatmap series on some map images and have that image scale and translate according to the chart's zoom level using the
{ roam: true }option. The data points represent coordinates associated with the map image. These maps are stored as png files in our server and not as an asset in the frontend because the available map images are dynamic.Here is an abstracted example that is similar to our codebase: https://codesandbox.io/s/echarts-geo-map-with-image-wfvvn?file=/src/index.js
I thought maybe the problem is that the svg is being drawn onto the canvas before the image is done loading so I tried registering the map after load. That didn't work either. Example: https://codesandbox.io/s/echarts-geo-map-with-image-registermap-after-image-load-iq1wn
