Tutorial for Data-Driven Charts 005 – Bubble Charts

Working with Bubble Charts

Bubble charts plot three variables: two variables based on the x and y axes and also volume, which is shown as bubble size. If you plot the data to show different colors for the bubbles, a fourth variable is added. Use legends to identify the what the colors mean (use to009 to create legends).

When a template from this series is put into your company's presentation template, the colors will change to your template's color scheme. Since the the bubble template will assume the defaults set in your company's presentation template, you may need to make some adjustments to the font size, color, whether it has bullets, etc.


Customizing data-driven charts

Adjust size

To adjust the size of a data-driven chart, you must double click on it and then adjust it by pulling the corner handles. Do not size without double-clicking on the chart. The text will skew and the chart may even eventually corrupt if you size incorrectly. This is important. The text may scale as you do this (which is an option you can choose or not choose). We recommend that you do not scale your text, as font size consistency is important for readability.


Color variations

The colors for data-driven charts are determined by your template's color scheme or palette. Your template needs to reflect the branded colors of your template or your charts will fail to do so. If you need to augment the colors in your template, select complementary or contrasting colors that work well with your palette. Then use them consistently.


3D variations

3D is okay to use with this type of chart. The 3D effect makes the circles look like spheres. It's very nice in certain circumstances. Make sure, however, that if you're using different colors for bubbles, there is enough difference between the colors. Adding the 3D effect slightly obscures the color due to the use of the gradients.


Shadows

Apply shadows carefully if at all. It's probably better to apply gradients, patterns, and pictures. You don't want anything to obscure the values or make them ambiguous.


Gradients, patterns, and pictures

Add gradients through the use of the 3D option.


Animations

Animate with a purpose. Simple reveals are much more effective than the more "startling" animations, unless of course you are trying to startle your audience. Add pizzazz by way of content, not by adding sparkly accessories.
