Regression Line on Line Series

[Phil]

I have a graph that shows the values of certain measures by time.  I wanted to create a regression line that I can toggle on and off.  I think i can handle the toggle on and off.  But wanted to know if there is any clever or easy way to do the regression line?

The only way I can see to do it is calculate the long way for each value in the series.

 

Thanks

Hi Phillip,

You will have to make custom calculations per X point and provide the final value in the Graph item's DataSource. then you can add LineSeries displaying the value.
The calculation can be done in the data-retrieval method, as a calculated field per row of data, or as an expression of the series' X|Y property.

Such calculations are not included in the graph item's functionality. Please feel free to log a feature request for having an option to add series based on specific formula and the graph's data.
