To plot the variation of pressure along the axis of rotation:, follow the steps below. You may also want to review this video from our laminar pipe flow tutorial which shows how to use the chart feature.

1. Create a line to represent the z-axis (axis of rotation)
   1. Select 'Location' > 'Line'
   2. Name it 'AxisRotation'
   3. Set Point 1 to (0,0,90)
   4. Set Point 2 to (0,0,-180)
   5. Change # of samples to 200
2. Create a chart
   1. Select 'Create chart'
   2. Under 'data series', create a new data series
   3. Set location to the line 'AxisRotation'
   4. Under 'x axis', set variable to Z 
   5. Check 'invert axis' because wind is traveling in -Z direction
   6. Under 'y axis', set variable to Pressure
