Steps to reproduce:
- Hover over "Edit" and click on "WYSIWYG"
- Click on "Macro>Insert Macro..."
- Click on the "Chart" macro
- Click "Select"
- Fill in the required fields
- Click "Insert Macro"
The macro won't be visible in WYSIWYG mode, but if you click on "Save & View" the chart is displayed. This bug doesn't exist on IE8/9 and Firefox. I've attached screenshots.
