I have this XY Chart panel
I’d like to add a 1:1 line to it:
I couldn’t find a way to do it, it doesn’t seem to be possible “natively” but I also couldn’t find a way to hack it, e.g. add a second series with 2 points (0,0) and (max_value, max_value).
Thoughts?

This would be a great toggle feature. Discussion related to regression support (and ideally 1:1) here:

Hey!
As user of plugin [XY Chart](https://grafana.com/grafana/plugins/xychart/) I'd like to request support for **regression lines** for this plugin.
Finally, a regression line should look e.g. like this:
**Expected Benefit**
A regression line transports the key message of a scatter plot to dashboard viewers **at a glance**.
It would be good to support different kinds of regression lines (Linear, Exponential, Power, ...) similar to the ones provided by the plugin [Scatter](https://grafana.com/grafana/plugins/michaeldmoore-scatter-panel/):
The **icing on the cake** would be the possibility for the dashboard creator to define the formula that is used to calculate the regression line.

Did you try Regression analysis transformation?
You may try Grafana’s Regression analysis transformation:
[Regression analysis]
To be able to use it you need to enable regressionTransformation feature toggle:
[feature_toggles]
enable = regressionTransformation
