Hello, I have a website that displays weather data using Teechart .NET v2 and Visual Basic. If I zoom into one webchart and then switch to a second webchart, the second webchart uses the same zoom level as the first webchart did.

Sorry, what about this then?

Code: Select all

         colorLine1.Value = DateTime.Parse("8/21/2007 11:14:00 AM").ToOADate();
That did it, thank you. Paul

You should use something like this:

Code: Select all

			colorLine1.Value = DateTime.Parse("8/21/2007 11:14:00 AM");
That generates an error..

Conversion from 'Date' to 'Double' requires calling the 'Date.YoOADate' method.
