In current version I can control either the whole pie radius or use some autocalculations with `roseType` option. But this is not suitable for our tasks. Earlier we used dashbords in PowerBI and the same feature in PBI looked like: <!-- ADD SCREENSHOT HERE IF APPLICABLE. -->   ### After: How does it behave after the fixing? <!-- THE RESULT AFTER FIXING AND A SIMPLE EXPLANATION ABOUT HOW IT IS FIXED. --> The solution is very similar with [scatter charts](https://echarts.apache.org/examples/en/editor.html?c=bubble-gradient) and its `symbolSize` option. Now (with this PR) i can pass custom function `itemRadiusScale`, which returns value from 0 to 1. That value is used within pie component to calculate outer radius for each item. In simple words, we now have a third dimension for each item, which means the size from center to the outer circle, almost like in scatter. Also, few calculated values (sum, maxValue) passed into `getDataParams` callback to make tooltip calculations easier. <!-- ADD SCREENSHOT HERE IF APPLICABLE. -->  ## Document Info One of the following should be checked. - [ ] This PR doesn't relate to document changes - [x] The document should be updated later - [ ] The document changes have been made in apache/echarts-doc#xxx ## Misc ### ZRender Changes - [ ] This PR depends on ZRender changes (ecomfe/zrender#xxx). ### Related test cases or examples to use the new APIs `test/pie-itemRadiusScale.html` here some content from the test file https://github.com/apache/echarts/assets/16826622/2464bf2c-48d4-4f20-b84b-c3a7c18e73d9 ## Others ### Merging options - [x] Please squash the commits into a single one when merging. ### Other information This is my first PR here.
