Trend is missing data points

Problem

Some transitions are skipped and corresponding data points do not show on the trend.

Cause

The trend object might be polling and updating with data periodically, rather than on change. For example, if data values change every second but the

Refresh Rate

is set to once per minute, changes in data will be missed.

Solution

On the General tab, change the chart update mode to

On Change

, or increase the speed of the

Refresh Rate

.
