Bug 214077 [Automation][Regression]Chart Y-axis step size is changed
Description: Chart Y-axis step size is changed to 1 when set the chart step size as default. Test Date: 20080102 Test Build: BIRT2.3.0 Daily Build: v20080102-1021 Step to reproduce: 1. Use the report attached 2. Preview it. Expect result: The step size should be 1000. Actual result: The step size is 1.
