QTDataVisualization only draw certain rows/cols of the QAbstractTableModel

mhsgoud

Hello, I am trying to visualize a table model using QTDatavisualization. I used existing example files and here is the code:

m_Proxy = new QSurfaceDataProxy(); 
m_Series = new QSurface3DSeries(m_Proxy); 

QItemModelSurfaceDataProxy *proxy = new QItemModelSurfaceDataProxy(model); 

proxy->setUseModelCategories(true); 
m_Series = new QSurface3DSeries(proxy); 
 
m_Series->setDrawMode(QSurface3DSeries::DrawSurfaceAndWireframe); 
m_graph->addSeries(m_sqrtSinSeries);

where model is QAbstractTableModel

This plots all the rows/cols interactively.

Question is: how can I make it only plot certain range of rows/cols from model? I know that I can set range for max/min in axis but that's not what I am looking for, I want to for instance remove first row and column data when plotting the graph, while the table should show those.

Thank you for your help.

Hi,

What comes to mind is to put a proxy model between your original model and the QItemModelSurfaceDataProxy. That proxy would only return the data that you want to be shown.
