Hello,

On my chart, I have a curve data and a linear regression line, and I’d like to display the results of the regression formula on the chart type
A.X = Y + B.
How does one on FlexPro?

Thank you in advance for your reply

Use the analysis object [b]Linear Regression[/b] (New|Curve Fitting|Linear Regression) to calculate the linear regression. Choose the result type [b]Dynamically calculated regression coefficients[/b]. Rename the analysis object into “Regression”.
Insert a label in the 2D-diagram with the content: Y = %{Regression[0]} + %{Regression[1]} * x

Why when I use “Calculate regression” coefficients calculated are accurate
(in our example a = 0.2359 …, and b = -4.4705 …)[img]uid6438_linear regression1.bmp[/img]

But showing on the curve, the result is not the same!

The script is correct. We cannot reproduce your problem. Perhaps the diagram is not up-to-date. Please click on [b]Update[/b] or [b]Force Update[/b].

If this suggestion doesn’t solve your problem, please send your database together with the information about your FlexPro version (8.0.xx) to support@weisang.com.

I found the problem, I had not checked the right option that is “the result type Dynamically calculated regression coefficients”
thank you for everything
