Covarians opened a new issue, #19155: URL: https://github.com/apache/echarts/issues/19155
### What problem does this feature solve? We would like to add line chart that are calculated from the values of other lines charts in the same graph. The calculation formula would be a javascript line of code entered by the user. We believe that the 'transform' function is ideal for that but the documentation only describes the inbuild (sort, filter) functions or the ecstats ones. ### What does the proposed API look like? So we could have a 'custom' type where we can define a custom javascript function that can use some data stored in the 'dataset' using their names. -- This is an automated message from the Apache Git Service.
