[vtkusers] vtkChartXY + tcl

[Mario Rodriguez]

Hello,

I want to experiment with vtkChartXY and tcl, but when I add this line 
to my script:

vtkChartXY chart

I get this error:

Error in startup script: invalid command name "vtkChartXY"
     while executing
"vtkChartXY chart"
     (file "prueba.tcl" line 21)

My environment is: Ubuntu 12.04 + VTK 5.8.

Could someone tell me what can I do from here?
