using LinearReg function

[dtrosty]

My goal is to chart a line consisting of the last points for each bar of the LinearRegression() function. This can be done using, for example, the ema() function.

LinearRegression() function behaves differenly. Examples:
middleLinearReg(20,1) returns a line of 20 poits ending with bar 0
middleLinearReg(20,1,0) returns nothing
middleLinearReg(20,1,-15) returns a line of 20-15=5 points ending with bar 0
middleLinearReg(20,1,-19) returns a single point for bar 0
middleLinearReg(20,1,10) returns a line of 20 points ending with bar -10.

How can I construct a stetement that will achieve my goal?
contrary to what the functional reference says about this function, the function does not return a single value for a bar specified in the nBarIndex parameter.

Thank you

But the example code posted above that is correct so use that. In this example you would use the myStudy2 series variable and pull single values from it with the .getValue() function.
