Is there any way in Qwt v5.2.1 to do side by side bar graphs with multiple sets of data colored differently to distinguish between the two? I'm trying to be specific in my question as possible. I'm right now using a HistogramItem but there is no way (that I know of) to attach more than one HistogramItem to a QwtPlot without upgrading to v.6.0.1 and using QwtBarItem and using that.
