Hello, @helgasoft @plainheart,
I've been looking into this issue and found that the default order for
splitArea.areaStyle.color in v6 is different from previous versions.
I found that by reverting the default color order in
src/coord/axisDefault.ts, the inconsistent behavior is resolved for heatmaps
with empty data. This fix works for both the Canvas and SVG renderers.
Here is the code change I tested locally:
Diff
```
/src/coord/axisDefault.ts
/src/coord/axisDefault.ts
@@ -121,8 +121,8 @@
splitArea: {
show: false,
areaStyle: {
color: [
- tokens.color.backgroundTransparent,
- tokens.color.backgroundTint
+ tokens.color.backgroundTint,
+ tokens.color.backgroundTransparent
]
}
},
```
This change directly fixes the visual inconsistency:
Before: The color of the top-left block is inconsistent with the rest of its
column. <img width="1062" height="571" alt="Image"
src="https://github.com/user-attachments/assets/a0648937-0088-407d-a393-a0e8f3cedc6a";
/>
After: The color is now consistent for both SVG and Canvas renderers. <img
width="1275" height="519" alt="Image"
src="https://github.com/user-attachments/assets/80b7a581-6cb0-4786-8522-84878cf015c9";
/>
Let me know if this seems like the right approach. If so, I would be happy
to create a pull request to resolve this issue. Thanks!
