Hi Pallav,
Am facing similar problem when the value is "0" and there is only 1 bar in the bar chart, it shows an ugly graph. But the same chart when there is one more bar with a >0 value it works well.
Since the data to be shown is dynamic, it can also have a value=0 for a bar. Also to be noted is that if there are 10 bars and all have a value 0 it still shows an ugly graph.
How can we solve it?
