[vtkusers] vtkChartXY live update

[Seun Odutola]

Hi Des,

    Thanks for the suggestion, I’m already doing that. I guess what am trying to achieve if I can rephrase my last post properly is that I need a way to have my table populated on the fly, that is if I start off with a table with say a single column, for each column I insert a value (essentially creating a row per column if I understand the API), then as I get new values, I want to be able to insert these values into the column. 

Regards,
   Seun

What I’ve gathered so far is that I need a vtkTable along with the vtkChartXY, I have gotten this to work so far so good. However, if I need to add more values to my table as time goes by and was wondering what the best way is in doing so.
