## Add a horizontal average line to a chart with a helper column

In Excel, charts are an effective way to visualize and analyze data. Sometimes, it can be helpful to add specific lines to a chart to highlight important information or trends. One of the commonly used lines is the horizontal average line, which represents the average value of the data points on the chart. In this tutorial, we will explore how to add a horizontal average line to a chart by utilizing a helper column.

Step 1: Prepare your data and create a chart: To begin, make sure you have the data you want to display in the chart ready in an Excel worksheet. Select the data range including both the category labels and the values. Then, go to the “Insert” tab and choose the desired chart type from the Chart group. Select the appropriate chart type that suits your data.

Step 2: Calculate the average using a helper column: To add a horizontal average line, we need to calculate the average value. To do this, create a helper column next to your data. In the first cell of the helper column, enter the formula “=AVERAGE(range)” without the quotes. Replace “range” with the actual range of data values. This formula calculates the average of the selected range.

Step 3: Add the helper column to the chart: Now, we will include the helper column in our chart. Right-click on the chart and choose “Select Data” from the context menu. In the “Select Data Source” dialog box, click on the “Add” button under the “Legend Entries (Series)” section. A new dialog box will appear.

Step 4: Configure the series settings: In the “Edit Series” dialog box, specify the following settings:

• “Series name”: Enter a suitable name for the series; for example, “Average.”
• “Series values”: Click on the icon next to the input field and select the range of values in the helper column you created earlier.
• “Series X values”: If your chart has categories, enter the corresponding range of category labels.

Step 5: Format the average series: To make the average line distinct, you can format it differently from the other data series. Click on the “Format” button in the “Edit Series” dialog box. Adjust the line color, style, and thickness to your preference. You can also customize other visual aspects such as marker style and fill color if desired.

Step 6: Apply the changes: Click “OK” to close the “Edit Series” dialog box. Then, click “OK” again in the “Select Data Source” dialog box. The average line will now be visible on the chart as a separate series.

Step 7: Fine-tune the appearance (optional): If necessary, you can further customize the average line’s appearance. Right-click on the average line in the chart and choose “Format Data Series” from the context menu. Experiment with different formatting options such as line type, color, or marker styles until you achieve the desired look.

Conclusion: By following these steps, you can easily add a horizontal average line to a chart by incorporating a helper column in Excel. This feature helps you highlight the average value within your data and provides valuable insights for analysis and comparison. Feel free to experiment with different chart types and formatting options to enhance the visual representation of your data.

## How to Add a Line to an Existing Excel Graph

Adding lines to an existing Excel graph can help emphasize specific data points, highlight trends, or display reference values. In this tutorial, we will explore how to add a line to an existing Excel graph step-by-step.

Step 1: Open your Excel workbook and select the graph: Open the Excel workbook containing the graph to which you want to add a line. Navigate to the worksheet that contains the graph and click on the graph to select it. The selected graph will be surrounded by a border.

Step 2: Activate the “Chart Tools” tab: Once the graph is selected, the “Chart Tools” tab will appear in the Excel ribbon at the top of the window. Click on the “Chart Tools” tab to access additional chart-related options.

Step 3: Select the “Layout” tab: Within the “Chart Tools” tab, you will see multiple tabs. Click on the “Layout” tab to reveal a variety of chart customization options.

Step 4: Choose the “Lines” category: In the “Layout” tab, locate the “Lines” group, which contains various line-related options for modifying the graph. Click on the small arrow icon located at the bottom-right corner of the “Lines” group to open the “Format” pane.

Step 5: Add a new line series: In the “Format” pane, you will find an option labeled “Series Lines.” Click on the “+” button next to it to add a new line series to the graph. This line series will be displayed as a line on the graph.

Step 6: Customize the line series: After adding the new line series, you can customize its appearance and data source. Use the available options within the “Format” pane to modify the line’s color, style, thickness, and more. You can also specify the data range or values for the line series by clicking on the “Select Data” button in the “Format” pane.

Step 7: Adjust the line position: To adjust the position of the line on the graph, you can use the data values or categories it represents. Depending on your requirements, you can select a specific data range or manually input values for the line series.

Step 8: Apply changes and review the graph: Once you have finished customizing the line series, click on the “Close” button in the “Format” pane to apply the changes. Take a moment to review the updated graph and ensure that the line has been added in the desired location.

Step 9: Fine-tune the line appearance (optional): If necessary, you can further refine the appearance of the added line by right-clicking on the line in the graph and selecting “Format Data Series” from the context menu. This will open a dialog box where you can make adjustments to the line style, color, marker options, and other visual properties.

## How to Add Average Line in Excel Pivot Chart

To enhance the insights gained from a pivot chart, it can be helpful to add reference lines like an average line. In this tutorial, we will explore how to add an average line to an Excel pivot chart.

Step 1: Create a PivotTable and PivotChart: First, ensure you have the data ready in a suitable format. Select the data range, including column headers, and go to the “Insert” tab. Click on the “PivotTable” button and choose the desired location for the PivotTable. In the “Create PivotTable” dialog box, select the data range and specify the destination for the PivotTable. Finally, click “OK” to create the PivotTable. Once the PivotTable is created, select any cell within it and go to the “Insert” tab again. Choose the appropriate chart type from the “Recommended Charts” section to create a PivotChart based on the PivotTable.

Step 2: Calculate the average in the PivotTable: To add an average line to the PivotChart, we need to calculate the average in the underlying PivotTable. In the PivotTable, locate the field that you want to find the average of (e.g., a numeric field). Drag that field to the “Values” area in the PivotTable Field List pane. By default, Excel summarizes the field values using the sum. To change this, click on the drop-down arrow next to the field name in the Values area and select “Value Field Settings.” In the “Value Field Settings” dialog box, choose the “Average” calculation method and click “OK” to apply the changes. The PivotTable will now display the average value for the selected field.

Step 3: Add the average line: To add the average line to the PivotChart, right-click on any data point in the chart and select “Select Data” from the context menu. In the “Select Data Source” dialog box, click on the “Add” button under the “Legend Entries (Series)” section. In the “Edit Series” dialog box, enter a suitable name for the series, such as “Average.” For the series values, select the cell containing the average value calculated in the PivotTable. Click “OK” to close the dialog boxes.

Step 4: Format the average line: To make the average line more visible, you can format it to differentiate it from other chart elements. Right-click on the average line in the PivotChart and choose “Format Data Series” from the context menu. Customize the line color, style, thickness, and other visual attributes according to your preference. You can also modify other aspects of the line, such as marker style and fill color if desired.

Step 5: Fine-tune the appearance (optional): If necessary, you can further refine the appearance of the average line by adjusting its position or adding additional formatting options. Right-click on the average line and choose “Format Data Series” from the context menu. Experiment with different formatting settings until you achieve the desired visual effect.
