@restyl1997,
I want to send an X value to this chart and have it selected, so the tool tip shows up where that X point is. How could I do that?
Showing toolTip programmatically is not possible as of now. However, this feature is there in our wish-list and would be available in future versions.
Additionally, I want to add a vertical arrow from the top of the red area to the top of the blue line as shown in the first image.
Adding arrow/custom drawing on chart is not available as an inbuild feature, as of now.
