Histogram is special in the way that the input data is not the data that is being shown in the chart - it needs to be calculated separately usign the input data. First we put the calculation in the (Histogram)DataInterpreter but that is not a very good place to calculate as we don't have the access to the chart properties and can't influence the calculation with it. This change puts the calculation into (Histogram)ChartType instead and will trigger the calculation when the data is requested. This is the first case of such a thing where we calculate the data on demand from the input data, so we will probably need further changes the chart code to better support calculated data sequences.
