I have a sparse set of values with x and y coordinates and a value that I want to show in a colour map. The number of values is known: lets say this in the variable `count`.
The valid range for x and y is known (0, width), (0,height)
When I call colorMap->data()->setSize() and setRange() what values should I use?
Right now I have coded:
colorMap->data()->setSize(static_cast<int>(lightFrameInfo.m_lWidth), static_cast<int>(lightFrameInfo.m_lHeight)); colorMap->data()->setRange(QCPRange(0, static_cast<double>(lightFrameInfo.m_lWidth)), QCPRange(0, static_cast<double>(lightFrameInfo.m_lHeight)));
Problem resolved - above code seems to work.
