I have compiled TeeChart with license in to a dll library file and used it in another application on another PC (non-license) so when I'm running this application the error appeared as follow: System.Windows.Markup.XamlParseException occurred Message="Cannot create instance of 'TChart' defined in as...

Thanks Narcis for your reply. Because our real time chart is added new data after refreshing, so we remove old series and rebuild series. But as you can see in our example, for this case, old data is displayed in a different way by time. (It is a special case, in fact our real time chart display a l...

Hi Steema, When we set DrawAllPoints = False, we recognized that TeeChart will take some points from all points to build serie randomly. For example: we have a set of data as following: X Y 2009-01-22-11.55.41.250000 1 2009-01-22-11.55.48.390000 1 2009-01-22-11.56.17.343000 1 2009-01-22-11.56.17.437...

Dear Steema, We have 8 series of a chart with much data that loaded from DB (over 500 000 points). We would like to read YValues of those series at a chart point when user click on a point in chart. Currently, we load data so that XValues is the same for the 8 series. By mouse position we use Axis.B...

Thanks Narcis,

Thanks again for your warm support.
My best regards.

Hi Steema, I want to move a colorline to middle of graph after zooming. Currently,I use event OnMouseDown to get previous bottom XValue, and OnMouseUp to get current bottom XValue. After zooming, i move colorline by setting colorline.value = (PreviousX+CurrentX)/2 But it was not good . Sometimes, th...

Hi Narcís,

From your investigate, the ActiveX version proves to be much quicker than the .NET version, why we should use TeeChart for .NET instead of TeeChart for ActiveX?

Thanks for your support.

Thanks a lot for your prompt support. About #3, I would like to clarify one more point: in our case, we have to develop an application that will be compiled into .NET managed code, however TeeChart Pro ActiveX is win32 based component, which means COM Wrapper mechanism must be used in our applicatio...
