I'm not asking echarts for a gradient. I use the `piecewise` visualmap type with several colors bands to represent value clusters; I.e. lower values are color 1, mid values are color 2, etc. The internal use of an SVG/Canvas `LinearGradient` is a design choice by echarts when using this visualmap type. It just so happens that this design choice degrades when the number of `pieces` exceeds ~63 (on my platform). Regarding how true my Scottish heritage is; this type of visual chart is common for showing fitness power zones in cycling time series data. > 3. Minimal Reproduction and video clips appear to have distinct code sources since they are so dissimilar in appearance... This is true. The videos should be self explanatory addendum to the core issue that is observable in the codepen link (which I created to satisfy the github issue requirements). If there is another codepen reference you would like, let me know and I'll make one. -- This is an automated message from the Apache Git Service.
