<DIV>Hi,</DIV>
<DIV>I am also plotting points from a std::vector<float> with a vtkXYPlotActor.</DIV>
<DIV>My code looks like this :</DIV>
<DIV> </DIV>
<DIV>std::vector<float> values;<BR>/* ... */</DIV>
<DIV>vtkFloatArray * Xarray = vtkFloatArray::New();<BR>vtkFloatArray * Yarray = vtkFloatArray::New();</DIV>
<DIV> </DIV>
<DIV>Xarray->Initialize();<BR>Yarray->Initialize();</DIV>
<DIV>for ( int i = 0; i < values.size(); ++i )<BR>{<BR> Xarray->InsertNextValue( i );<BR> Yarray->InsertNextValue( values[ i ] );<BR>}</DIV>
<DIV>vtkFieldData * FieldValues = vtkFieldData::New();<BR>FieldValues->AllocateArrays( 2 );<BR>FieldValues->AddArray( Xarray );<BR>FieldValues->AddArray( Yarray );</DIV>
<DIV>vtkDataObject * Data = vtkDataObject::New();<BR>Data->SetFieldData( FieldValues );</DIV>
<DIV>vtkXYPlotActor * XYplot = vtkXYPlotActor::New());<BR>XYplot->AddDataObjectInput( Data );<BR>XYplot->SetXValuesToValue();<BR>XYplot->SetDataObjectXComponent( 0, 0 );<BR>XYplot->SetDataObjectYComponent( 0, 1 );</DIV>
<DIV><BR>But I have a problem.</DIV>
<DIV>When I want to change the viewed values, I do the same thing just after a XYplot->RemoveAllInputs(), but it crashes...</DIV>
<DIV> </DIV>
<DIV>Hope this helps.</DIV>
