Description Laurent Balland 2014-01-09 21:04:32 UTC 
Created attachment 91776 [details]
Example of trenline equation which is nonsense

Problem description: 

Steps to reproduce:
1. Insert data X=1, 4, 8; Y=11, 12, 13
2. Create a *Line* type chart (no XY scatter) with X data as Categories
3. Insert trend line and check Show equation

Current behavior:
The equation shown (f(x) = x + 10) is not informative as its X-values are Categories which values are integers 1, 2, 3. User may think that X-values in equation are its X-data which is wrong.

Expected behavior:
Equation (and R^2) must not be displayed if chart type is not XY scatter.

However trendline can be shown, even if chart type is not XY scatter, as it can be interesting to show the trend.

This has been discussed on the qa list and was rejected. You can disable the equation if you don't want it.
