ToughRover commented on issue #9381: 散点图当piecewise visualMap和y轴使用同一列数据时内容无法显示

   I do not know how echarts handle the series data inside, actually the data I passed to series is a 2 columns, n rows data array, So I use dimension 1 as Y axis value as well as visualMap. It appears to me echarts copied the column for visualMap in this special case, this is not reasonable since users do not know the behavior of copying of a column after the original data is passed to echarts option. So I cannot define the correct dimension for visualMap in this special case. The behavior should be consistent with common case. (visualMap and y axis uses different column).
