Hi Paul,<br>
<br>
I use Qwt library <<a href="http://qwt.sourceforge.net/" target="_blank">http://qwt.sourceforge.net/</a>> and its QwtPlot class. It should do what u want.<br>
<br>
Cheers<br>

Hi,<br>
<br>
I am trying to figure out how to draw a chart where the data for a line is made up of x,y coordinates.<br>
<br>
It seems that vtkQtLineChart can only draw a line series where each value is at a sequential X coordinate. My data is not at sequential x coordinates (it may skip a bunch).<br>
<br>
thanks,<br>
Paul<br>
