I’m unable to draw trendlines accurately. The starting point of the trendline shifts away from the point I selected. The same issue also occurs with channel lines.

Hi @S O ,

Thank you for contacting us.

Is this happening only in one project or across all projects?

Please send me a link to the project where you see this issue.
If possible, also record a short video showing the trendline or channel line shifting after you select the starting point - that will help us review it faster.
