for(int i=0;i<data_show_C.size();i++)
      {
          for(int j=0;j<data_show_C[i].size();j++)
          {
                double z =data_show_C[i][j];
                mcolorMap->data()->setCell(i,j,z);
          }
      }

When I use the setcell function, the program will report an error index out of bounds, but I have no problem printing data with debug. Who can help me？


void QCPColorMapData::setCell(int, int, double) index out of bounds: 0 0
void QCPColorMapData::setCell(int, int, double) index out of bounds: 0 1
void QCPColorMapData::setCell(int, int, double) index out of bounds: 0 2
