A chart data range is a setting on an Excel chart that defines the range of data that the chart will use. It is a range of cells that you select when you create a chart in Excel. The range of cells can include labels, values, or dates. You can also use the chart data range to define the source data for a chart. The chart data range can be set to use a static range of values or to dynamically update with data from an external source.

Click the “Select Data” button to open the “Select Data Source” dialog box. In the “Select Data Source” dialog box, click on the “Edit” button next to the “Chart Data Range” field. This will open the “Edit Series” dialog box where you can enter the new data range for the chart. Editing the Chart Data Range To edit the chart data range, enter the new data range in the “Series values” field. You can either enter the data range as a cell reference (e.g. A1:A10) or as a named range. If you enter the data range as a named range, make sure to select the appropriate range from the drop-down list. Once you have entered the data range, click “OK” to save the changes and close the “Edit Series” dialog box. Then click “OK” again to save the changes and close the “Select Data Source” dialog box. Your chart will now be updated with the new data range. Adding a New Series of Data If you want to add a new series of data to the chart, click the “Add” button in the “Select Data Source” dialog box.

Macro Method The macro method allows you to automate the process of changing the chart data range.

Creating the Macro To create the macro, open the Visual Basic Editor (VBE) by clicking the “Developer” tab in the ribbon and then clicking the “Visual Basic” button. This will open the VBE where you can write the macros. You will need to write a macro that changes the data range of the chart based on certain criteria. For example, you could use the “Change Chart Data Range” macro to change the chart data range when the data in a certain range changes. Running the Macro Once the macro is written, you can run it by clicking the “Run” button in the VBE. The macro will then change the chart data range based on the criteria you specified. You can also set up the macro to run automatically when the data changes by using the “Auto_Open” macro.

This allows you to create a chart that will always display the most up-to-date data. To do this, select the “Dynamic Range” option in the “Select Data Source” dialog box and enter the external source’s address.
