I plotted a stacked chart with some values. Say one of the dataset the values are 10,20,30,40. it means 0 to 10, 0 to 20, 0 to 30 and 0 to 40. But the chart is plotted as

first value 0-10

second value 10-30 (which is 20)

Third value 30-60 (which is 30)

fourth value 60-100 (which is 40)

Is there any way to plot the chart as i need 0 to 10, 0 to 20, 0 to 30 and 0 to 40.

Thanks in Advance
