Excel is a powerful tool that allows users to create visually appealing and informative charts and graphs. One of the most useful features of Excel is the ability to add a secondary axis to a chart. This feature allows users to plot two different data sets with different units of measurement on the same chart. In this article, we will guide you through the steps of adding a secondary axis in Excel.
Step 1: Prepare your data
Before adding a secondary axis, it is essential to have your data ready. Ensure that you have two sets of data with different units of measurement. For example, you might have one data set with values representing sales in dollars and another data set with values representing the number of units sold. Having two distinct data sets is necessary for creating a chart with a secondary axis.
Step 2: Create a chart
Once your data is prepared, select the data range you want to include in your chart. You can do this by clicking and dragging your mouse over the desired cells. After selecting the data, go to the “Insert” tab in the Excel ribbon and choose the chart type that suits your needs. The most common chart types are bar, line, and column charts.
Step 3: Add data to the chart
After creating the chart, it is time to add the data sets. To do this, right-click on the chart, and from the context menu, select “Select Data.” In the “Select Data Source” dialog box, click on the “Add” button under the “Legend Entries (Series)” section. Give a name to the new data series and specify the range of cells containing the values you wish to add to the chart. Click “OK” to close the dialog box and return to the chart.
Step 4: Format the chart
With the new data set added, you will notice that Excel has plotted it using the same axis as the first data set. To change this, select the series representing the new data set by clicking on any data point in that series. Right-click on the selected series and choose “Change Series Chart Type” from the context menu.
In the “Change Chart Type” dialog box, select a chart type that suits your second data set. For example, if your first series is a bar chart, you may want to select a line chart for the second series. Click “OK” to apply the changes.
Step 5: Add a secondary axis
To add a secondary axis, right-click on one of the data points in the series representing the second data set. In the context menu, select “Format Data Series.” The “Format Data Series” pane will appear on the right side of the Excel window.
In the “Format Data Series” pane, navigate to the “Series Options” tab. Under the “Plot Series On” section, choose the option “Secondary Axis.” Excel will immediately add a secondary axis to your chart, allowing you to plot the second data set with its own set of units and scale.
Step 6: Format the secondary axis
To ensure that the secondary axis displays the correct format, right-click on the secondary axis and select “Format Axis.” The “Format Axis” pane will appear on the right side of the Excel window.
In the “Format Axis” pane, you can customize the appearance of the secondary axis. You can choose a different scale, adjust the units, and modify the appearance of the ticks and labels. Make any desired changes and click “OK” to apply them.
In conclusion, adding a secondary axis in Excel is a valuable feature that allows you to present multiple sets of data with different units of measurement on the same chart. By following these simple steps, you can create informative and visually appealing charts that efficiently convey complex information. So, go ahead and start exploring this feature to enhance your data analysis capabilities in Excel.
