Annotation in version 6.2 (WindowsForms)

Recommended Posts

Support Service,

I have a problem trying to plot a note(annotation) on the chart (WindowsForms). So I created a simple project and repeated the procedure and the error still persists.

On the event Highlighted() of the chart, I tried to plot a note(annotation) by adding the 'Extention' chart.Extensions.Add (***), which is giving an error on the screen (one red'X'on the entire chart).

I'm using version 6.2 of the Chart. I wonder if there is a problem with this component on this version, because I did the same for version 7 and it worked.

(On my atual code I can not migrate to version 7, I must continue using version 6.2 and I need to solve it!)

I am sending the code.

I need an answer with the most urgency. We work with Oil and Gas Projects, and we are about to deliver/deploy a new version.

Thanks in advance and waiting for your response.

Karin
