A wind diagram has bins that go from 0 to 360 by default but the starting angle can be adjusted as needed. To center the first bin on 0 degrees
Let's say your bins are in 22.5 degree increments and you wish to have the first bin centered over 0.
- In the Object Manager, select the wind chart.
- On the Plot tab in the Property Manager, set the Start angle to 348.75.
- Change the Bar width to 22.5.
