Picking and Editing

In either the regular developer version or the Lite version of the tChart .NET component, can points shown on a graph be visually edited? For example, can a single point be selected and moved around with the trace line updating in realtime?

Hi Jon,

Yes, this can only be achieved with TeeChart for .NET Professional versions as Lite versions doesn't include chart tools. The tool necessary for this is Drag Points tool. You'll find examples of its usage at All Features\Welcome!\Tools\Drag Point in the features demo. The demo can be found at TeeChart's program group.

Very good. Now, this raises a question for me: how easy should it be to upgrade to the Professional version, install it, and then subsequently have those capabilities available to me without having to do much (or any) code changes? I don't want to have to go into my code and remove the old charts, and add the new charts. That would be a big mess!

Hi Jon,

It should be pretty easy. I'd recommend you to install Professional version on your machine and replace TeeChart's assembly reference in your projects from TeeChart.Lite.dll to TeeChart.dll.
