Range on trend chart is not as expected

Problem

The range of values shown on a trend chart is not what you expect it to be. For example, the pen's minimum and maximum values are configured as 1 and 100, but the chart shows a range from -50 to 50.

Cause

The trend object offers a variety of range options, controlled by options set on the Y-Axis tab. The pen's minimum and maximum values might fall outside of the specified range or outside of the specified scale configured on the Y-Axis tab.

Possible solutions

On the Y-Axis tab, check the following:

  • Which Minimum / Maximum Value option is selected.
  • Which Scale option is selected.
