If you are not allowed to add secondary columns, which cannot be completed individually with clustered column or stacked column charts, this article describes a method for displaying two seed chart types without secondary columns in a double axis, as shown in the figure.
Operation Steps
1, select a cell in the data range, select "Insert → column chart → stacked column chart" in the Ribbon.
2. Right-click the "Lost Customer" series, select "Set series format" in the pop-up shortcut menu, and set the series to secondary axis in series options.
3, add two empty series. Right-click the chart again, select Select Data from the shortcut menu, pop the Select Data Source dialog box, click the Add button, and eject the Edit Data Series dialog box. Under series name, enter a name, in this case "a", under "series value", Change "={1}" to "={0}", and click OK.
4, add another empty series "B", Return to the "Select Data Source" dialog box. Select Drain customer, click the Move Down button to move it to the bottom, and click OK.
5, change the chart type of series in the secondary axis. Right-click the Lost Customer series, select Change series chart type from the shortcut menu, and change the chart type to clustered column in the pop-up dialog box.
The chart below shows the diagram below.
