Office hacks: Chart type smart switch

This can be achieved by generating a chart data source with a defined name and changing the chart type with the help of simple VBA.

First, the chart data source worksheet in the storage of blank space to enter the required content of the drop-down menu. For example, enter the month and region in cells P1:P2. Select the “Development Tools” tab, click “Insert → ActiveX Control → Combo Box”, in the appropriate location on the worksheet to draw a combo box, select the combo box, click “Properties “, in its properties window, LinkedCell, enter “Q1”, ListFillRange, enter “P1:P2”, click BackColor to set its background color.
