*The tutorial shows how to insert vertical line in Excel chart including a scatter plot, bar chart and line graph. You will also learn how to make a vertical line interactive with a scroll bar.*

In the modern versions of Excel 2013, Excel 2016 and Excel 2019, you can add a horizontal line to a chart with a few clicks, whether it's an average line, target line, benchmark, baseline or whatever. But there is still no easy way to draw a vertical line in Excel graph. However, "no easy way" does not mean no way at all. We will just have to do a little lateral thinking!

To highlight an important data point in a scatter chart and clearly define its position on the x-axis (or both x and y axes), you can create a vertical line for that specific data point like shown below:

Naturally, we are not going to "tie" a line to the x-axis because we don't want to reposition it every time the source data changes. Our line will be dynamic and will react to any data changes automatically.

To add a vertical line to Excel scatter chart, this is what you need to do:

- Select your source data and create a scatter plot in the usual way (
*Inset*tab >*Chats*group >*Scatter*). - Enter the data for the vertical line in separate cells. In this example, we are going to add a
**vertical average line**to Excel chart, so we use the AVERAGE function to find the average of x and y values like shown in the screenshot:**Note.**If you'd like to draw a line at some**existing data point**, extract its x and y values as explained in this tip: Get x and y values for a specific data point in a scatter chart. - Right-click anywhere in your scatter chart and choose
**Select Data…**in the pop-up menu.

- In the
*Select Data Source*dialogue window, click the**Add**button under*Legend Entries (Series):*

- In the
*Edit Series*dialog box, do the following:- In the
*Series name*box, type a name for the vertical line series, say*Average*. - In the
*Series X value*box, select the independentx-value for the data point of interest. In this example, it's E2 (*Advertising*average). - In the
*Series Y value*box, select the dependenty-value for the same data point. In our case, it's F2 (*Sales*average). - When finished, click
*OK*twice to exist both dialogs.

**Note.**Be sure to**delete the existing contents**of the*Series values*boxes first - usually a one element array like ={1}. Otherwise, the selected*x*and/or*y*cell will be added to the existing array, which will lead to an error. - In the
- Select the new data point in your chart (orange in our case) and add the
**Percentage**error bars to it (*Chart Elements*button >*Error Bars*>*Percentage*).

- Right-click on the
**vertical**error bar and choose**Format Error Bars…**from the context menu.

- On the
*Format Error Bars*pane, switch to the*Error Bar Options*tab (the last one) and set**Percentage**to 100. Depending on your needs, set**Direction**to one of the following:- Set
*Direction*to**Both**if you'd like the vertical line to go**upwards**and**downwards**from the data point. - Change
*Direction*to**Minus**for the vertical line to go only**downwards**from the data point.

- Set
- Click the
**horizontal**error bar and do one of the following:- To
**hide**the horizontal error bars, set**Percentage**to 0. - To
**display**a horizontal line in addition to the vertical line, set**Percentage**to 100 and choose the desired**Direction**.

- To
- Finally, switch to the
*Fill & Line*tab and choose the**Color**and**Dash**type for the currently selected error bar. You can also make the line thinner or thicker by changing its**Width**.

Done! A vertical line is plotted in your scatter graph. Depending on your settings in steps 8 and 9, it will look like one of these images:

If you'd like to compare the real values with the average or target you wish to achieve, insert a vertical line in a bar graph like shown in the screenshot below:

To create a vertical line in your Excel chart, please follow these steps:

- Select your data and make a bar chart (
*Insert*tab >*Charts*group >*Insert Column or Bar chart*>*2-D Bar*). - In some empty cells, set up the data for the vertical line like shown below.
X Y Value / formula 0 Value / formula 1 Since we are going to draw a

**vertical average line**, we calculate the**X value**as the average of cells B2 through B7:`=AVERAGE($B$2:$B$7)`

This formula is inserted in both X cells (D2 and D3). Please notice that we use absolute cell references to ensure that the formula copies to a second cell without changes.

- Right click anywhere in your bar chart and click
**Select Data**in the context menu:

- In the popped-up
*Select Data Source*dialog, click the**Add**button:

- In the
*Edit Series*dialog box, make the following changes:- In the
*Series name*box, type the desired name (*Average*in this example). - In the
*Series values*box, select the cells with your**X values**(D2:D3 in our case). - Click
*OK*twice to close both dialogs.

- In the
- The new data series is now added to your bar chart (two orange bars). Right click it and pick
**Change Series Chart Type**in the pop-up menu.

- In the
*Change Chart Type*dialog window, do one of the following depending on your Excel version:- In Excel 2013, Excel 2016, Excel 2019 and later, select
**Combo**on the*All Charts*tab, choose**Scatter with Straight Lines**for the*Average*series, and click*OK*to close the dialog. - In Excel 2010 and earlier, select
*X Y (Scatter)*>*Scatter with Straight Lines*, and click*OK*.

- In Excel 2013, Excel 2016, Excel 2019 and later, select
- In the result of the above manipulation, the new data series transforms into a data point along the primary y-axis (more precisely two overlapping data points). You right-click the chart and choose
**Select Data**again.

- In the
*Select Data*dialog, select the**Average**series and click the**Edit**button.

- In the
*Edit Series*dialog box, do the following:- For
*Series X values*, select two X cells with your Average formulas (D2:D3). - For
*Series Y values*, select two Y cells containing 0 and 1 (E2:E3). - Click
*OK*twice to exit both dialogs.

**Note.**Before selecting the cells with your X and Y values, please remember to clear the corresponding box first to prevent errors.

A vertical line appears in your Excel bar chart, and you just need a few finishing touches to make it look right. - For
- Double-click the secondary vertical axis, or right-click it and choose
**Format Axis**from the context menu:

- In the
*Format Axis*pane, under*Axis Options*, type 1 in the**Maximum bound**box so that out vertical line extends all the way to the top.

- Hide the secondary y-axis to make your chart look cleaner. For this, on the same tab of the
*Format Axis*pane, expand the*Labels*node and set**Label Position**to**None**.

That's it! Your bar chart with a vertical average line is finished and good to go:

- To
**change the appearance**of the vertical line, right click it, and select*Format Data Series*in the context menu. This will open the*Format Data Series*pane, where you can choose the desired dash type, color, etc. For more information, please see How to customize the line in Excel chart. - To add a
**text label**for the line like shown in the image at the beginning of this example, please follow the steps described in How to add a text label for the line.

To insert a vertical line in a line graph, you can use either of the previously described techniques. For me, the second method is a bit faster, so I will be using it for this example. Additionally, we will make our graph interactive with a scroll bar:

To add a vertical line to an Excel line chart, carry out these steps:

- Select your source data and make a line graph (
*Inset*tab >*Chats*group >*Line*). - Set up the data for the vertical line in this way:
- In one cell (E1), type the text label for the data point at which you want to draw a line exactly as it appears in your source data.
- In two other cells (D3 and D4), extract the
**X value**for the target data point by using this formula:

`=IFERROR(MATCH($E$1,$A$2:$A$7,0), 0)`

The MATCH function returns the relative position of the lookup value in the array, and the IFERROR function replaces a potential error with zero when the lookup value is not found.

- In two adjacent cells (E3 and E4), enter the
**Y values**of 0 and 1.

With the vertical line data in place, please follow steps 3 - 13 from the bar chart example to plot a vertical line in your chart. Below, I will briefly walk you through the key points.

- Right-click anywhere in the chart, and then click
**Select Data…**. - In the
*Select Data Source*dialogue box, click the**Add**button. - In the
*Edit Series*window, type any name you want in the*Series name*box (e.g.*Vertical**Line*), and select the cells with**X values**for the*Series values*box (D3:D4 in our case).

- Right click anywhere in the chart and choose
**Change Chart Type**from the pop-up menu. - In the
*Change Chart Type*window, make the following changes:- On the
*All Charts*tab, select**Combo**. - For the main data series, choose the
**Line**chart type. - For the
*Vertical Line*data series, pick**Scatter with Straight Lines**and select the**Secondary Axis**checkbox next to it. - Click
*OK*.

- On the
- Right-click the chart and choose
**Select Data…** - In the
*Select Data Source*dialog box, select the*Vertical**Line*series and click**Edit**.

- In the
*Edit Series*dialog box, select the X and Y values for the corresponding boxes, and click*OK*twice to exit the dialogs.

- Right-click the secondary y-axis on the right, and then click
**Format Axis**. - On the
*Format Axis*pane, under*Axis Options*, type 1 in the**Maximum bound**box to ensure that your vertical line extends to the top of the chart. - Hide the right y-axis by setting
*Label Position*to**None**.

Your chart with a vertical line is done, and now it's time to try it out. Type another text label in E2, and see the vertical line move accordingly.

Don't want to bother typing? Fancy up your graph by adding a scroll bar!

To interact with the chart directly, let's insert a scroll bar and connect our vertical line to it. For this, you will need the Developer Tab. If you don't have it on your Excel ribbon yet, it is very easy to enable: right-click the ribbon, click *Customize Ribbon*, select *Developer* under *Main Tabs*, and click *OK*. That's it!

And now, perform these simple steps to insert a scroll bar:

- On the
*Developer*tab, in the*Controls*group, click the*Insert*button, and then click**Scroll Bar**under*Form Controls*:

- On top or at the bottom of your graph (depending on where you want the scroll bar to appear), draw a rectangle of the desired width using the mouse. Or simply click anywhere on your sheet, and then move and resize the scroll bar as you see fit.
- Right click the scroll bar and click
**Format Control…**.

- Link your scroll bar to some empty cell (D5), set the
**Maximum Value**to the data points total and click*OK*. We have data for 6 months, so we set the*Maximum Value*to 6.

- The linked cell now shows the value of the scroll bar, and we need to pass that value to our X cells in order to bind the vertical line to the scroll bar. So, delete the IFERROR/MATCH formula from cells D3:D4 and enter this simple one instead:
`=$D$5`

The *Target month* cells (D1 and E1) are not needed any longer, and you are free to delete them. Or, you can return the target month by using the below formula (which goes to cell E1):

`=IFERROR(INDEX($A$2:$A$7, $D$5, 1), "")`

That's it! Our interactive line chart is completed. That took quite a bit of time, but it was worth it. Do you agree?

That's how you create a vertical line in Excel chart. For hands-on experience, please feel free to download our Excel Vertical Line sample workbook. I thank you for reading and hope to see you on our blog next week!
