I have a chart and would like to add two new pieces of data to the chart. How do I do that?
To add an additional data series to an existing chart, double click on the chart to put it into Edit mode, then right click to get a dialog box. Choose Data Ranges. Under the Data Series tab, click on Add and proceed to supply the required information for the new series.
There are a number of powerful tools provided for editing of charts – the labels, titles, axes and their formats, lines and symbols, etc. You are encouraged to experiment.
