Internal Comms Measurement 101: Choosing the Right Graph to Tell Your Data Story

Internal comms professionals are turning their attention to measurement. Internal comms measurement is key to earning a seat at the table, tracking results, and creating strategies that deliver on business objectives. But data and analytics are sometimes out of our comfort zones. So, in this blog we’re reviewing a few common types of graphs and when to use them. For a more in-depth explanation check out this chart guide from Storytelling with Data.

Line Graphs 

This chart type is best used to illustrate changes over time or to compare how several things change over time in relation to one another.

You’ll use line charts to show trends over time. So, for example, you would use line graphs to show app or newsletter opens over time. Or you can use this to show average video view duration over time. This is a great visual to see if new or modified tactics are paying off.

But do not use a line graph for:

  • Comparing parts to the whole
  • Displaying quantities of things (that’s what bar charts are for!)
  • If change over time has nothing to do with what you are trying to visually represent

Bar Charts

There are many types of bar charts. This chart variety is used to graph categorical data or data sorted into groups for comparison. The classic vertical bar chart is likely the most familiar to you, but a horizontal bar chart is useful when you have longer category names. You can also use stacked bar charts to illustrate the parts or components of a given category and compare the categories.

As an internal comms pro, a few examples of how you might use bar charts include:

  • To visualize results to Likert Scale and multiple choice survey questions that you want to share back to leadership.
  • To visualize who attended your most recent town hall based on job title, location, department, etc.

Area Graphs 

This chart type is a special type of line graph where you fill in the region between the line and the x-axis with a solid color to impact how we perceive the data. Note that you can show positive and negative data—some area charts go below the x-axis to show the fall in your data set. Unlike your regular line graph, these show part-to-whole relationships over time.

You might use area graphs to show a trend over time (like line graphs) but also what makes up that total. For instance, you might want to show content opens over time, but you also want to illustrate what types of content make up the total opens. This would let you show, for example, how your podcast, videos, and PDF/Text based content perform in relation to one another over time.

Pie Charts

This chart type is very often misused. They are used to express a part-to-whole relationship. Period. But unfortunately, they are sometimes used to compare data. But it is very difficult to compare two separate pie charts side-by-side. So, keep that in mind.

But also remember that sometimes pie charts are used and the slices aren’t different enough in size. When the parts are all similar in size, it can be difficult to see the trend or point of the data visualization. So these charts are really great for when one part is relatively small or big compared to everything else.

Pie charts can also be used to represent survey answers, especially when there is a clear top or bottom answer.
