Hi,<br><br>I observed that vtkChartLegend is used in vtkPVXYChartView.<br><br>Code:<br> void vtkPVXYChartView::SetChartType(const char *type)<br>{<br>// Construct the correct type of chart<br> if (strcmp(type, "Line") == 0 || strcmp(type, "Bar") == 0)<br>
{<br> this->Chart = vtkChartXY::New(); // in vtkChartXY ctor, vtkChartLegend is created<br> }<br><br>In my customRenderView, is it possible to use this vtkChartLegend. Can you please suggest how do I get similar ChartLegend in my view?<br>
<br>Appreciate your help in this regard.<br><br>Thanks in advance,<br>Hanumanth.<br><br><div class="gmail_quote">On Fri, Mar 9, 2012 at 5:25 PM, Pandu tech <span dir="ltr"><<a href="mailto:pandu4tech@gmail.com">pandu4tech@gmail.com</a>></span> wrote:<br>

am trying to implement a legend in a new view that I have created. I
would like to get information from the data currently visible (typically
field data stored in the dataset) and populate the legend box with
this. My view is derived from vtkPVRenderView and I can add a
vtkLegendBoxActor but I’m not sure how I get the information I want in
order to update it. Is it possible to either request information about
the object from the server or get the information from the
representation? If so, where do I need to implement this? </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal">
