Invalid dimansion-line chart of linear regression using 'Advanced Analutics Toolbox' extension

[danielmor1993]

Hello,

I am creating my first linear regression in Qlik Sense,

I used this tutorial: https://github.com/mhamano/advanced-analytics-toolbox/blob/master/docs/analysis/simple_linear_line.m...

In the dimenstion I put a date field (DD/MM/YYYY) and in the measure I put a numeric (Sum()) field (like in the example in the URL)

I got 'Invalid dimension' error (attached pic):

In a regular line chart with the same fields, I see the results (attached pic):

What am I doing wrong?

Thank you,

Daniel
