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

Example:
October 12, 2009 at 10:58 pm #8765Bernhard KantzParticipantUse the analysis object Linear Regression (New|Curve Fitting|Linear Regression) to calculate the linear regression. Choose the result type Dynamically calculated regression coefficients. Rename the analysis object into “Regression”.
Insert a label in the 2D-diagram with the content: Y = %{Regression[0]} + %{Regression[1]} * xOctober 13, 2009 at 8:10 pm #8766sylvain bressieuxMemberWhy when I use “Calculate regression” coefficients calculated are accurate
(in our example a = 0.2359 …, and b = -4.4705 …)But showing on the curve, the result is not the same!
October 14, 2009 at 6:26 pm #8767Bernhard KantzParticipantThe script is correct. We cannot reproduce your problem. Perhaps the diagram is not up-to-date. Please click on Update or Force Update.
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.

thank you for everything -
