Learn about tips to create clean charts in PowerPoint.

The biggest bane of charts seen on PowerPoint slides is that they are too crowded, include too much detail that’s much more than what audiences want, and have so little white space. By white space of course, we don’t just mean space that is colored white – rather we mean empty, breathing space. If we had to sum up what we need in two words, then those two words would be “clean charts”.
To bring attention to what a clean chart is, we must first look at a chart that is not clean! Look at Figure 1, where you can see
a moderately bad chart. Why do we call this a moderately bad chart? That’s because we have seen charts that are so much worse than this specimen.

If we just follow a few guidelines and five minutes of effort, the same chart you saw earlier can be transformed into what you see in
Figure 2, below.
Figure 2: A better chart
There’s such a huge difference between the charts you see in Figures 1 and 2. First of all, we abandoned the 3D chart type in favor of a cleaner, flat look. We also removed the value axis altogether since we already have data labels. It makes no sense to include individual data labels and then also provide a value axis, since that’s essentially duplicated information. We moved the legend to the top right so as to give more white space in between the column groups. Finally, we reduced the opacity of gridlines to make them less prominent.
Whenever possible, try to make your charts clean – here are some guidelines that will help you:
- Imagine a clean, harmonious background for your slide that you don't want to crowd -- this will make it easier for your chart to stand out
resulting in the audience being able to review the chart more attentively.
Have you ever tried doing a very important project on a very cluttered desk? Chances are you realized that a clean desk can help you create a better project because you can concentrate more. It's the same with the audience -- they can assimilate information presented on a slide better if it contains a clean chart on a clean background.
- To create a clean chart, only retain chart elements that are needed. Yes, you
must add the actual chart but not much else.
You don't always need a legend, data labels, axes labels, titles, plot lines, too much data, or even too much extra text. And you most certainly do not need them all at the same time! Limit yourself to the fewest number of chart elements as you can.
- Some slides have many charts. Even four charts in a single slide may be too many, but we have seen slides that had sixteen charts! If your audience cannot decipher the chart content at such a small size, is there any sense in following this approach? Think about it!
