This script will add trend and average lines to any column chart (as far as I've tested)
It calculates the average for each point on the x axis and then the trend line for the chart.
Copy and paste the attached script to the widget's custom script to see!
- Sometimes the dashboard needs to be refreshed with F5 to display the lines
- Selecting a section of the dashboard does not mute the rest of the line, the whole line is fully visible.
