using FinancialFormula we can use only one RegressionType like Linear , Exponential , Logarithmic , Power will display in single chart (asp.net chart control). Is it possible to add all these four regression types to chart. How can we do that? or is there any free chart control that support these?
From your description, It sounds like you're using Microsoft's chart control. These forums are for Infragistics controls only. You should post this question on Microsoft's forums.
Our chart control currently doesn't have built-in regression formulas, but it is possible to plot multiple regression lines if you're willing to calculate the regression yourself.
