Bug 192585 The Tube/Cone/Pyramid Chart Y Axis type will be Date/Time after change type to Gantt then change back [0001]
Description: The Tube/Cone/Pyramid Chart Y Axis type will be Date/Time after change type to Gantt then change back Build number: 2.2.0.v20070614-0939 Steps to reproduce: 1. Drag a chart from the Palette to the Layout. 2. Select chart type as Gantt, then change to Tube/Cone/Pyramid. Expected result: The Chart in the preview pane is the same as the one when chart builder first opened. Actual result: Their Y Axis type change to Date/Time(see the screenshot). Error log: N/A
