By default, EasySpreadsheet will insert your chart as a bar/pictograph chart; however, the chart type can easily be changed using the Chart Designer.
To change the chart type:
Double-click the chart with your left mouse button.
Right-click the chart once. A menu will appear.
Click Chart Designer. The Chart Designer window will open.
In the box on the left, ensure that Chart is selected.
Click the Type tab.
Here, you can:
Choose a chart type from the list (Line, Area, Step, etc.).
Choose to have a two-dimensional (2D) or three-dimensional (3D) chart.
Choose to display your data by rows, instead of by columns. To do so, check off Data in Rows.
When you are done, click Apply, and then OK.
