Bug 179913 Meter Chart color by categories with null values does not work correctly [0001]
Description: Meter Chart color by categories with null values does not work correctly. Build number: 2.2.0.v20070329-1055 Steps to reproduce: 1. New a Meter Chart with values as follows: Moto, null; Nokia, 58; null, 66; Benq, null. 2. In "Format Chart" tab, select "Series" node, choose "Color by Categories". 3. Preview. Expected result: 1. The needle which shows the second value should take the second color. 2. There should be four in the legend area and the third name is null. Actual result: 1. The needle which shows the second value should take the first color. 2. There should be three in the legend area. Error log: N/A
