This is indeed a bug with _dataZoom_ **filterMode** "empty" and "none". > is there a way to get the original default y-axis value range, and then set its min and...

There is a difference in [data.lineStyle](https://echarts.apache.org/en/option.html#series-tree.data.lineStyle) implementation: - for edgeShape **polyline** - it describes the **downward** connection lines, to children (see "flare") - for edgeShape **curve** - it describes the...

yes, something fishy going on. Chart cannot be updated between bar and polar, but can be **replaced**. And only after adding a _series.id_. Weird...

A small study on **ECharts transitions**. Charts could be separated in two major groups - **with** (bar,line,etc.) and **without** (pie,polar,graph,etc.) **axes**. Transition between charts is done through [setOption](https://echarts.apache.org/en/api.html#echartsInstance.setOption) or [morphing](https://echarts.apache.org/handbook/en/basics/release-note/5-2-0)....

_visualMap_ would have been the solution here, but looks like it does not work with _sankey_. Like: ``` visualMap: { categories: ['1', '2', '3'], dimension: 'category' // does not work...

gosh, how do you find this stuff ?! It's a bug in the **first data point for SVG line** - does not like a _null_ mixed with other values. ```['Alpha',...

I think _cartesian2d_ heatmap is just a color matrix. API says [pointSize](https://echarts.apache.org/en/option.html#series-heatmap.pointSize) and _blurSize_ are valid only with _geo_ coordinate system. So _cartesian2d_ points cannot be merged on zoom, like...

Tooltips show only on _mouseover_, not on _click_.
