How to create fix width bar chart with variable number of data points in iOS?


I am trying to plot a chart using Shinobi Premium version.  I am using SChartColumnSeries to plot bar chart, the width of the bars is adjusted according to the frame available to plot the chart. I want it to be fixed (say 20 pixels) regardless of number of bars present and if the data points are too large, then chart should be scrolled to view the remaining column bars. I have enabled both zoom and pan functions. I want the width of the column chart to be fixed. How can I achieve this using Shinobi charts?
