How to Alter Data Range in a Bar Graph in Excel
Bar graphs are a popular way to visualize data, especially when comparing different categories or groups. In Excel, creating a bar graph is straightforward, but what if you need to alter the data range that the graph represents? This article will guide you through the process of altering the data range in a bar graph in Excel, ensuring that your graph accurately reflects the data you want to present.
Understanding the Data Range
Before you can alter the data range in a bar graph, it’s important to understand what the data range is. The data range is the set of cells that contain the data you want to graph. When you create a bar graph in Excel, you can specify the data range by selecting the cells that contain your data.

2. Right-click on the bar graph and choose “Select Data” from the context menu. This will open the “Select Data Source” dialog box.
3. In the “Select Data Source” dialog box, you will see a list of data series in the “Chart Data Range” box. This is the current data range for your bar graph.
4. To add a new data series, click on the “Add” button. This will open the “Edit Series” dialog box.
5. In the “Edit Series” dialog box, you can enter the range of cells that contain the new data series. You can either type the range manually or click on the “Select Range” button to select the range from your worksheet.
6. Once you have entered the new data range, click “OK” to close the “Edit Series” dialog box.
7. Repeat steps 4-6 for each additional data series you want to add.
8. After you have added all the necessary data series, click “OK” in the “Select Data Source” dialog box to apply the changes to your bar graph.
Adjusting the Data Range for Existing Series

2. Click on the “Edit” button to open the “Edit Series” dialog box.
3. In the “Edit Series” dialog box, you can modify the range of cells for the data series. Make the necessary changes and click “OK” to save them.
