Any method to set optimal zoom level based on x-axis item count & label length?

[soorajlh]

I am using BarChart with grouped datasets. The problem is by default the X-Axis is sometimes too congested or too much zoomed. So I need a method to set default horizontal zoom level depending on no if items in x axis & if possible trim values with ellipse & show full label when we zoom in Also for the required functionality, the dataset size is dynamic. Sometimes when the dataset size is 1 the first bar size is smaller than other bar sizes.
