User Problem

Trend lines are not available in Line charts, scatter plots, or bar charts in Analytics.

We'll have to use a Bar line chart and calculate the trend in separate columns to show the line. 

Suggested Solutions

Similar to Annotations, I would like to add trend line to all the possible chart types with click of a button

Current Workarounds

Use a bar line chart to show the trend in a separate column and show that using the line. 

1. Create a third column in a bar line chart.
2. Group it using Average or Mean based on your requirement.
