Need help on Line Chart with Multiple Variables

Hi there,

This is my first post on this forum, so bare with me.
I am trying to chart the performance of telesales personnel at my workplace.
I would like to use a line chart to 'chart' their performance over a period of time (so Y-axis = Date).

The Variables are:

Total Call Time
Total Talk Time

I would like the option to expand the chart as time progresses, so I can continue to update the chart with staffs performance, and get a clear picture of their avg. performance over time.

Please find attached the data sheet.

Any help on this would be greatly appreciated.

Many thanks
Alex
