[vtkusers] vtkChartXY live update

[Andras Lasso]

Why would you recreate the table? You can add rows and columns to an existing table. See how it is done in 3D Slicer:

https://github.com/Slicer/Slicer/blob/master/Libs/MRML/Core/vtkMRMLTableNode.cxx

(AddColumn, AddEmptyRow methods)

You mean like appending to an existing table on the fly, without
re-creating the table? I would be curious about this too!

Cheers,

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.
