Chart for specific date from drop down box

Hi,

I have a file which have 2 column for data for a specific date. This data keep adding every day and 2 new columms get add for new data.

I want to create a chart for the that 2 column of data with a drop down box so that it can show data for that day which was selected from drop down box. Also, new data and new date in drop down box should add automatically.

I am also enclosing a file to make this statement more meaningful.

Please see the attached file and give me suggestion, if anyone have.

Thanks and Regards
