Icons are a great way to visualize ideas and compare different variables. Now you really can compare apples, oranges, and even bananas!
To use different icons in the pictorial charts:
❶ Click to select your chart;
❷ Expand the Icons tab in the right sidebar.
From there, you can change icons for each of your data categories (represented by rows in your chart's data table).
To change icon size:
❶ In the right side settings panel expand the Chart properties tab.
❷ In the Icon size tab, choose Small, Medium or Large.
And if you want to use different icons for each tab in your chart, check out the article about Changing settings for each data sheet.
