# Pen is missing from the trend chart

## Problem

A configured pen does not show on the trend.

## Possible solutions

On the Pens tab, make sure that:

- The Visible option is On.
- The pen line color is not the same color as the chart's background color specified on the Display tab.
- The pen has a marker assigned, if the Data Point Connection option on the Display tab is set to Show Only Markers.

On the Y-Axis tab, check the chart range, as defined by the Minimum / Maximum Value options. If the pen's data is all outside of the specified range, the pen's trend line draws at the top or bottom of the chart, where it might not be noticeable.
