How do I amend a chart

I have created a chart but now wish to extend the data range and can’t understand how I can do so.

Hi

You can add data points with drag and drop. The “trick” is to select the all data set (not just the new points) and then drag and drop them on the chart.

And, more traditionally, you can Double click the chart to enter edit mode, then Right click Data Ranges.
