Need help to create Dynamic range stacked bar chart

Hello Team,

I am creating a Stacked bar chart which can increase and decrease the range of chart dynamically.

like i have data in column A and column B

Column A Column B
Test1 10
test2 20
Test3 30

So it should only come up for these 3 data values , if i will delete data from test3 then it should supress this from chart and the chart should come up for only test1 and test2.

Please see my attached excel for more info.

Thanks
