# 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.
