All you need to do is loop through your table column names and the call SetColumnVisibility(vtkStdString name, bool visible) for the ones you want to appear. Note that there is also a convenience method SetColumnVisibilityAll(bool visible) in case you want to turn them all on, or want all off so you can just turn on a select few.</div><div><br></div><div>-Eric</div><div><br></div><div><br><div><div>On Mar 31, 2011, at 6:38 PM, Darshan Pai wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Eric,<br><br>Is there an upper limit to the number of axis the Parallel Coordinates defaults too ?<br>I was just trying for 17 , but i does not allow me anything greater than 10 .<br><br>Regards<br>Darshan<br><br><br><div class="gmail_quote">

Hey Darshan,<br>
<br>
Because there's still a slight bug in the plot class you have to set the line opacity through the plot's Pen rather than through the lookup table. You also set the line width through the Pen (this is Python, so you may have to do some casting in C++):<br>
<div><br>
chart.GetPlot(0).GetPen().SetOpacityF(0.8)<br>
</div>chart.GetPlot(0).GetPen().SetWidth(6)<br>
<br>
You set the scalar range for each axis (index i) by first calling chart.GetAxis(i).SetBehavior(1) to set it to a "fixed" range rather than auto-rescaling, and then you call chart.GetAxis(i).SetMaximum() and SetMinimum(). If you want/need to then specify where the ticks are and what their labels are, then you need to call chart.GetAxis(i).SetTickPositions() with a vtkDoubleArray of position values and SetTickLabels() with a vtkStringArray of labels.<br>

> So i updated to the current nightly build . Now I see that the category colors are correct , but the output is transparent . I changed the opacity of the plot and set it to 1 but still the output lines are very light . Is there any way to change this behaviour . Also can I change the line Size ?<br>
