Supported Sensors: Sensors with both 1x Phase and 1x Magnitude or 2x Phase and 2x Magnitude features.

You can use a polar plot to display data in polar coordinates, enabling you to see phase changes in the range of zero to 360 degrees. The polar plot zero degree point is always located at the angular position of a transducer. You can compare data from orthogonally-mounted displacement probe pairs with a polar plot.

What do you want to do?

Task Action
Change the angle direction between clockwise and counterclockwise. On the Properties tab of the Asset Configuration page, set the Rotation Direction as either clockwise or counterclockwise.
Remove the slow-roll value from sensor data so the plots start at 0. To compensate for slow-roll in magnitude and phase data, configure the 1x Magnitude Reference and 1x Phase Reference sensor properties on the Properties tab of the Asset Configuration page. These are properties of the sensors that acquire data.
Tip  If you notice that the configured reference values are incorrect or you want to temporarily use different values, you can override the properties with values that are calculated from sensors data.

Change the order of the magnitude. Click Order on the viewer toolbar and select either 1x Magnitude or 2x Magnitude.
Select the source sensor. If you have more than one feature selected in the asset tree, you can select the source sensor for the viewer by clicking Choose Assets on the viewer toolbar.
Disable auto-scaling to manually set the scale for the viewer. Click Set Scale on the viewer toolbar. Uncheck Auto-scale and set the maximum and minimum values you want the viewer to use.
