exce+training - Charts

Hi Anna, Thanks for the post, to answer your question; have your worksheet with the chart on it open, and click on the chart to select it, you will notice that the Menu Option for Data is now reading Chart; from this menu choose Chart Type, this will open a dialog box which will allow you to choose a different type of chart, proceed and select your preferred layout of the chart.
If you wish to view the chart from a different perspective, whilst the chart is selected, from the Chart Menu choose Source Data and select either Rows or Columns to change the view.
Advanced Charting is covered in our Excel Intermediate Course.
I hope that helps,
regards Pete
