When using a Bar chart type that contains more data points than are shown on the screen (i.e. the chart shows a subset of the data from the middle of the set), the leftmost and rightmost bars are drawn (clipped) across the left and right edges of the charting area so that only half a bar is shown. This is visually disconcerting.
Is there any way to specify a padding value or make it so that the chart area shows only an integral number of bars on the screen at any one time?
