Contour chart is [defined](https://github.com/apache/echarts-custom-series/tree/main/custom-series/contour) as _"connecting points of equal value (e.g., elevation or intensity) with contour lines"_. But it looks like it's in fact a **density** (also called heatmap) chart. Library _d3_ is used to draw areas around adjacent points. [This example](https://codepen.io/helgasoft/pen/bNVjEVy) shows several issues with current code: * chart is not positioned correctly on X and Y axes, or axes are incorrectly drawn * encode is defective for axes and tooltip * dataZoom has problems with all _filterMode_ options * tooltip shows the same value everywhere, it is the last value from data * ```appendData``` does not work, maybe in general for all custom types (?) Contours were discussed in [#13909](https://github.com/apache/echarts/issues/13909), and I said that _"contours are already feasible in ECharts with series type 'line' or 'custom-polygon'"_. Maybe just rename this one from "contour" to "density chart" ? PS: the heatmap chart with ```coordinateSystem:'geo'``` displays similar density effect - [example](https://codepen.io/helgasoft/pen/GRGqZeR). -- This is an automated message from the Apache Git Service.
