RadChartView - user should be able to enter minimum/maximum width for Bars in BarSeries.
The size of the bars in a bar series chart is defined by the number of data points and the availbale plot area. You can control how much space the bar(s) take for each individual tick throught the CategoricalAxis GapLength property. On the particular case for this feedback item we have added a constraint that bars a cannot be less then 1px in width for vetical charts and 1px in height for horizontal charts. This should ensure data is always displayed no matter how dense the chart is.
