How to find, highlight and label a data point in Excel scatter plot

The tutorial shows how to identify, highlight and label a specific data point in a scatter chart as well as how to define its position on the x and y axes.

Last week we looked at how to make a scatter plot in Excel. Today, we will be working with individual data points. In situations when there are many points in a scatter graph, it could be a real challenge to spot a particular one. Professional data analysts often use third-party add-ins for this, but there is a quick and easy technique to identify the position of any data point by means of Excel. There are a few parts to it:

The source data

Supposing, you have two columns of related numeric data, say monthly advertising costs and sales, and you have already created a scatter plot that shows the correlation between these data:

Now, you want to be able to quickly find the data point for a particular month. If we had fewer points, we could simply label each point by name. But our scatter graph has quite a lot of points and the labels would only clutter it. So, we need to figure out a way to find, highlight and, optionally, label only a specific data point.

Extract x and y values for the data point

As you know, in a scatter plot, the correlated variables are combined into a single data point. That means we need to get the x (Advertising) and y (Items sold) values for the data point of interest. And here's how you can extract them:

  1. Enter the point's text label in a separate cell. In our case, let it be the month of May in cell E2. It is important that you enter the label exactly as it appears in your source table.
  2. In F2, insert the following VLOOKUP formula to extract the number of the sold items for the target month:


  3. In G2, pull the advertising cost for the target month by using this formula:


    At this point, your data should look similar to this:
    Extract x and y values for the data point of interest.

Add a new data series for the data point

With the source data ready, let's create a data point spotter. For this, we will have to add a new data series to our Excel scatter chart:

  1. Right-click any axis in your chart and click Select Data….
    Excel scatter plot: Select Data
  2. In the Select Data Source dialogue box, click the Add button.
    Select Data Source dialogue box: Add
  3. In the Edit Series window, do the following:
    • Enter a meaningful name in the Series name box, e.g. Target Month.
    • As the Series X value, select the independent variable for your data point. In this example, it's F2 (Advertising).
    • As the Series Y value, select the dependent In our case, it's G2 (Items Sold).
  4. When finished, click OK.

Adding a new data series to the scatter graph.

As the result, a data point in a different color (orange in our case) will appear among the existing data points, and that is the point you are looking for:
The target data point is highlighted in a different color.

Of course, since the chart series update automatically, the highlighted point will change once you type a different name in the Target Month cell (E2).

Customize the target data point

There are a whole lot of customizations that you can make to the highlighted data point. I will share just a couple of my favorite tips and let you play with other formatting options on your own.

Change the appearance of the data point

For starters, let's experiment with colors. Select that highlighted data point, right click it and select Format Data Series… in the context menu. When doing so, please make sure that only a single data point is selected:
Scatter graph: Format Data Series

On the Format Data Series pane, go to Fill & Line > Marker and choose any color you want for the marker Fill and Border. For example:
Changing the color of the found data point

In some situations, using a different color for the target data point may not be appropriate, so you can shade it with the same color as the rest of the points, and then make it stand out by applying some other maker options. For example, these ones:
Circle the target data point in the scatter graph.

Add the data point label

To let your users know which exactly data point is highlighted in your scatter chart, you can add a label to it. Here's how:

  1. Click on the highlighted data point to select it.
  2. Click the Chart Elements button.
  3. Select the Data Labels box and choose where to position the label.
    Adding the data point label
  4. By default, Excel shows one numeric value for the label, y value in our case. To display both x and y values, right-click the label, click Format Data Labels…, select the X Value and Y value boxes, and set the Separator of your choosing:
    Display x and y values on a label.

Label the data point by name

In addition to or instead of the x and y values, you can show the month name on the label. To do this, select the Value From Cell check box on the Format Data Labels pane, click the Select Range… button, and choose the appropriate cell in your worksheet, E2 in our case:
Label the data point by name.

If you want to show only the name of the month on the label, clear the X Value and Y Value boxes.

As the result, you will get the following scatter plot with the data point highlighted and labeled by name:
The target data point is highlighted and labeled by name.

Define the position of the data point on x and y axes

For better readability, you can mark the position of the data point important to you on the x and y axes. This is what you need to do:

  1. Select the target data point in a chart.
  2. Click the Chart Elements button > Error Bars > Percentage.
    Add error bars to the scatter chart.
  3. Right-click on the horizontal error bar and choose Format Error Bars… from the pop-up menu.
    Format Error Bars…
  4. On the Format Error Bars pane, go to the Error Bar Options tab, and change Direction to Minus and Percentage to 100:
    Formatting the horizontal error bar.
  5. Click the vertical error bar and do the same customization.

    As the result, the horizontal and vertical lines will extend from the highlighted point to the y and x axes, respectively:
    The horizontal and vertical lines define the position of the target data point on the x and y axes.

  6. Finally, you can change the color and style of the error bars so that they better fit the colors of your chart. For this, switch to the Fill & Line tab of the Format Error Bars pane and choose the desired Color and Dash type for the currently selected error bar (vertical or horizontal). Then do the same for the other error bar:
    Changing the color and style of the error bars

And here comes the final version of our scatter graph with the target data point highlighted, labeled and positioned on the axes:

The best thing about it that you have to perform these customizations only one. Due to the dynamic nature of Excel charts, the highlighted point will change automatically as soon as you input another value in the target cell (E2 in our example):
The highlighted point on the scatter chart changes automatically.

Show a position of average or benchmark point

The same technique can also be used to highlight the average, benchmark, smallest (minimum) or highest (maximum) point on a scatter diagram.

For example, to highlight the average point, you calculate the average of x and y values by using the AVERAGE function, and then add these values as a new data series, exactly as we did for the target month. As the result, you will have a scatter plot with the average point labeled and highlighted:
A scatter plot with the average point labeled and highlighted

That's how you can spot and highlight a certain data point on a scatter diagram. To have a closer look at our examples, you are welcome to download our sample workbook below. I thank you for reading and hope to see you on our blog next week.

  1. You automatically assume that the graph will show every row of data in it when you click on the chart and try and find values using the Series Points x symbols on the chart. I have 194 rows of data conforming to weekly results and yet the line chart just show 5 July 2021 then the next data point on the line graph is 2 Nov 2021? Why won't it show all WEEKS as Series Points on the graph so I can easily see what the weekly prices were when I hover over the line chart?

  2. Is it possible to change the size of data points in a graph?
    e.g. make them larger than the default size

  3. When selecting a single point on a chart, then Data Labels | Options, as you show "Label Options" and then "Label Contains" show up. Under "Label contains" I see 5 things, not 6. The item missing, as compared to your screen shot, is "Value From Cells". The boxes that i can check under "Label Contains" are "Series Name", "X Value", "Y Value", "Show Leader Lines" and "Legend Key".

    Do you know if a recent Excel release eliminated "From Cell" as an Option here, or do you know any other reason why "From Cell" might be missing for me? I wish i could post a screen shot, but i've described it as best i can.

    What i want is "From Cell" if you know any way i can get to it, to workaround this, please let me know.

    Thank You!

  4. In scatter (bubble) plots there are often groups separated by breaks in the numerical values in the x axis. It might be useful to have a vertical line separating these groups that goes from the x axis to the top of the chart. In this way the horizontal axis can be labeled and identified more clearly

    It is easy to do this with the select line in objects and simply draw the vertical line from the top to bottom between groups. But, the line does not move with the chart.

    It doesn't seem the examples given here work for this situation.

    Thank you. I'm probably not the best excel person. Ha!! I may be wrong in my assessment. Mike

  5. thx

  6. Good afternoon,
    Im wondering if there is any way to label the peaks of Y values. like in chromatography. My chart has 3000 points so I need to highlight only some of the highest values. Thank you in advance and have a great day

    • Yes, I also would like to know this.
      And also whether you can have point series labels appear only when you hover over the point.

  7. I graphed my blood pressure readings with 4 columns of data. The first column is the date, second is the diastolic reading, third is the systolic reading, and fourth is the heart rate. I successfully graphed the diastolic and systolic readings as a LINE graph, but I wanted to display the heart rate readings on that same graph as a SCATTER plot. All data IS graphed correctly, BUT, there are ADDITIONAL points on the scatter plot that I DID not include in the columns of data.

    When I put the cursor on those additional points, it shows point, and a number, and value, and a number. The VALUE matches where that point is on the graph, but I have no idea where the POINT number comes from. All these additional points are vertical, and they are all on the first date of my information,

    Can anyone tell me where these addition points and values came from, and how I can delete them from my graph?

    Your help will be greatly appreciated and ease my frustration immensely.

  8. How to plot two different labels other than X,Y from values in different columns in XY scatter graph. One value above data point and second value below data points.

  9. Thanks for saving my life. I appreciate it.

  10. excellent explanation regarding excell graphics, plots, etc.

  11. How can I format multiple points like this at the same time (but not the entire data set)?

  12. I created a chart in excel with multiple lines. I have added the legend. I would like to know how I can add the latest data point of each series to its legend, i.e. in the legend box, not to the lines of the chart. Can you help?

    • Hi Floris,

      You can change the legend labels in this way:

      1. Right-click the legend, and click 'Select Data…'

      2. In the 'Select Data Source' box, click on the legend entry that you want to change, and then click the Edit button.

      3. The 'Edit Series dialog' window will show up. The 'Series name' box - it's where Excel takes the label for the selected legend entry. You can either type the desired text in that box, e.g. ="Apples 10", or you can add a reference to the cell that contains the latest data point (click in the box, and then click the cell). If you add a cell reference, the legend label will updated automatically as soon as you change the corresponding value in the source table.

      4. Click OK twice to close both dialog windows.
