Hi, I want to color the axis label by its value,
eg.
value < 0 -> show red color
value = 0 -> show gray color
value > 0 -> show green color
similar to this question, but in javascript platform, it seems the LabelProvider has function related to the value(string) formatting only. Is there any ways to styling the label? Thanks!

Very good question. Let me ask the team and revert back to you. May I ask *why* ? what is the use-case
hi andrew, for example, the X axis is the date. When I enter a new month or a new year, we hope that the label can change color, so that users can more easily notice that it is a new month or a new year.

Hi there,
I’ve spoken to the Javascript team and they tell me you can override LabelProvider.getLabelTexture() to achieve a custom style per label.
Try this:
// Override in LabelProvider
public getLabelTexture(labelText: string, textureManager: TextureManager, labelStyle: TTextStyle) {
const num = parseFloat(labelText);
const customStyle: TTextStyle = num < 0 ? { color: "red", ...labelStyle } : { color: "green", ...labelStyle };
return textureManager.createTextTexture([labelText], customStyle, this.rotationProperty);
}
We have some documentation on Custom Label Providers including images for axis labels here. This may be helpful
Let me know if that helps!
Best regards,
Andrew
