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.
