How to Create Powerful Graphs & Charts in Microsoft Excel

Gavin Phillips 19-02-2016

The power of a good graph is undeniable.


Taking numerical concepts and displaying them in an easy to digest, comprehensible visual representation can be the difference between someone grasping your idea, and someone grasping for the phone. To call security. Because your big pitch sucked. Your potential investors didn’t engage with what you were talking about, and I’ll tell you what – you should have used a graph.

Graphs and charts do not have to be all bells and whistles, either. Remember the graphs you made in Excel when you were nine? Exactly. Lime-green Comic Sans is not the way to go. But we can set you right, right here, right now.

I’m using freely available UK government data. Of course, if you have your own data, please feel free to use that.

The Quick Graph Use Outline

One of the biggest crimes against any chart or graph is its improper use. Here is a jolly quick outline of what to use, and when:

  • Use a line chart to display and emphasize trends in data over time
  • Use a bar chart or pie chart to compare categories, though the latter usually compares parts of a whole
  • Use an area chart to highlight the change of values over time
  • Use a scatter chart to plot multiple data points

These cover the core charts you may encounter, and equally, the charts you are most likely to use. There are other chart types – bubble, sparkline, bullet, and more – but we’ll focus on formatting How to Make Your Graphs & Tables Look More Professional Tired of your data tables and graphs looking like they were made by a high schooler? Here's how to make them look more professional. Read More these.

I’ve highlighted the first two columns.

Now, head to the Insert tab, and select Insert line chart – it’s the small box with plotted lines. You should now have a nice new plain chart. From here you have two options: use the inbuilt Excel styles, of varying quality, or customize the chart yourself.


Excel Basic Line Chart

Chart Styles

Chart Styles can be accessed to the right of the chart area, as illustrated below. You can choose from a number of styles, as well as colors. Our graph currently only features one set of data, so the color choice will have little effect, but as more are added, colors will help your potential audience discern between different sets of information.

Excel Preset Styles

Axis Formatting

Note the vacuous space underneath our line? It is space we could be putting to better use. Click the vertical axis. It will open the Format Axis window. Here we can change the bounds, units, tick marks, labels, and more. We can see the bounds of our data range from around 50,000 to just over 62,000, meaning we can raise the minimum bound from 0.0 to 50000.


See the immediate effect this has on the graph? The rising population is now pronounced, whereas before it could be considered a gentle increment.

Excel Reduced and Increased Bounds

We should also give our axis a title. Press the plus symbol to the right of the chart, then Axis Titles, followed by Primary Horizontal and Primary Vertical. You can now edit each title to match your chart. I’ve used Population for my vertical, and Period for my horizontal. I’m also going to increase the font by one point, and make the titles bold so the audience can actually read them.

Adding a Secondary Axis

Now, we’d like to add additional data series to our chart, but simply expanding the data selection range won’t do the job. Why? The values in the first column are in the tens of thousands. However, the values in the following columns are only in the hundreds, and at points down to single digits. Our current vertical axis range cannot accommodate the lower values – so we will add a secondary axis.


First of all, I’ll expand the data selection range to encompass Live Births and Deaths. Next, right-click the chart area and select Change chart type. Select Combo from the left-hand column. It should all become clear now! I can now select the chart type and axis for each data series. I’m going to use line chart, and add the final two data series to the secondary axis, as per the below image:

Excel Combo Chart

And the chart itself:

Now that we’ve plotted our new data series, we’ll need a legend. In some cases, a legend is unnecessary, but when you have intersecting lines, using two axis, it is worth giving your audience a chance of understanding your data. Turn on the legend by pressing the plus symbol to the right of the chart, then legend. If you press the small arrow, you’ll be able to select the legend location. In this case the legend should be placed at the bottom of the chart.

Excel Legend Location

To change the legend titles, right-click the chart area and click Select Data. In the left-hand column of the new window you should spot your unnamed data series. Select the first one and press Edit. You can now enter your preferred name for the data series.

Excel Select Data Range


When you’re ready, press OK, and your legend should automatically update How to Create Self-Updating Microsoft Excel Charts in 3 Easy Steps Self-updating Excel charts are huge timesavers. Use these steps to add new data and watch them automatically show up in a chart. Read More .

Excel Data Range Name Data Series

Now, go ahead and add a title to the second axis using the same method we explored earlier. Again, I would make the font one point larger, and make the title bold.

Our newly introduced data series are looking a little flat. In the raw data, we can see a couple of major variances in both births and deaths, so let’s make sure the chart reflects that. As we did with the first data series, we’ll adjust the secondary axis options. Click on the secondary axis. I’m going to adjust the minimum bounds to 400, and the minor unit to 100.

Excel Axis Bounds Options

Margins and Titles

Next, we’ve got some large margins at either end of our chart, and that won’t do. Double-click the horizontal axis – Period – and change the Axis position from Between tick marks to On tick marks. Our lines will now fill the entire chart area, rather than denying the passage of time.

Excel Chose Axis Postion

Finally, choose a snappy, descriptive title, and do not be afraid to use a sub-title to convey exactly what your chart is showing. I’ve gone for UK Population Change 1951-2011; United Kingdom Population Change in Thousands. Okay, so maybe it isn’t that snappy, but my audience will know exactly what they’re looking at, and what values the numbers are expressing.

That was a line chart, good for emphasizing trends over time. Now we’ll look at the bar chart. This time, using the same table, we are going to look at the Live Births, Deaths, Net natural change, and the Overall Change.

Start by selecting each of the aforementioned columns, and heading to Insert > Clustered Bar.

Upside Down?

You’ll immediately notice your chart is upside-down. That is to say, Excel has reversed the organization of your chart categories. My chart begins with 2010-2011, and finishes with 1951-1961. This won’t do, as most people will logically read the chart from top to bottom. Double-click the vertical axis (or press Ctrl+1 when the axis is selected) to bring up the Axis Options. Locate and select Categories in reverse order.

Excel Categories in Reverse Order

You’ll now spot your horizontal axis has jumped to the top of your chart. In the same Axis Options panel, select At maximum category.

Axis and Chart Area Formatting

Double-click the horizontal axis to open the Axis Options. Our data doesn’t contain a value higher than 1000, so reduce the Maximum Bound to 1000. You now have two options: keep the Major Unit as 200, which is quite suitable for our chart, or reduce this to 100, which also works. I’m going with 100 as we have a number of data series with similar values between the two potential units. This will make it easier to discern between the similar values.

Our bars are quite thin, too. Make them stand out by clicking one of the data series and, in the Series Options sidebar reduce the Gap Width to 125%, adding some visual weight to our data.

Excel Axis Gap Width

Title and Legend

As our table contains more than one form of data, Excel has kindly supplied a legend detailing each data series. Increase the font size of the legend by one point.

Give your bar chart a snappy, descriptive title. If your chart is part of a series, make sure the title reflects the rest of your data. In this case, I’m going to use the same title as our line chart – UK Population Change 1951-2011 – but we’ll give it a contextual subtitle: Annual Averages: Live Births, Deaths, and Overall Change.

Chart Styles

Our chart is now formatted, and if you were to show it to an audience, they’d understand the data. But we haven’t looked at Excel’s built-in styles. Some are slightly useless, their colors and general formatting the antithesis of useful, while others are surprisingly handy.

Excel Styles Side by Side

We can also choose from a range of color schemes.

Excel Colour Presets

To the right of the chart is a paintbrush icon, located underneath the plus symbol. Depending on your audience, move through the preset styles and consider if this would make the impact you need, and if the style allows your data to do the talking. Consider the preset colors, too. I’ve changed my chart from the standard blue, yellow, orange, grey affair to a color-set exemplifying the differences between Live Births, Deaths, and the Net Natural Change.

Chart Experiments

We’ve shown you a nice range of Excel charts, and we’ve given you some tips on when to deploy them. If you’re still unsure of the power of graphs, consider this recent experiment where individuals were presented with clear, factual information contradicting their world view, but the data was displayed in a more compelling format. The researchers tested three strategies:

  • Presenting a paragraph of text that summarized the factual evidence
  • Presenting the evidence in a chart
  • Building up subjects’ self-esteem so they’d feel less threatened.

The most effective method of data transmission? Simple, clean charts, displaying information in a language that was easy to understand.
