Trying to layer a vertical range box behind the main candlestick plot, but the annotation always stays on top.
I've set barSeries.zIndex(1); and tradeRange.zIndex(0);
I've also tried setting the annotation before setting the candle series in the file.
I note that annotations use a different library. Are they always going to be on top?
For now I'm using transparency as a fix, but a full solution would be welcome.
To ensure an annotation appears below your main chart series, you need to explicitly set the zIndex of your series higher than the zIndex of the annotations controller.
We've created a Playground example that demonstrates how to render annotations behind the series:
Annotation Below Series – Playground
You can also refer to the API reference for the Annotations Controller zIndex for more detailed control over annotation layering.
By assigning a lower zIndex to the annotations controller and a higher zIndex to your series, the chart will render the series on top of the annotations as intended.
