Curve Fitting

Hello,

I have never used the curve fitting feature so I first need to check with you guys :) I have a scatter plot of points and I need to fit these points with the curve : y=a*X^b. Is this possible?

Re: How to calculate Y from X value (LineSeries with Smoothing)

Hello Urank, I am guessing that your series values will contain all additional points calculated by the smoothing function so you can find Y as the intersection of 2 line segments. You just need to find the index value so that XValues < Your_X < XValues[i+1] and test the intersection of this line se...

Re: A problem with bar color, please help.

Hello,

I tried to modify the example so that it can work with 2 Horizontal lines series but it does not work as expected. Is it too much to ask for a sample code? I need to paint the hatched region only. Maybe this could also included in the Tools section?

Re: A problem with bar color, please help.

Hello Narcis,

Would it be possible for you to arrange an example for Horizontal Line Series? I tried to implement this solution to a chart with THorizLineSeries but it looks like the CrossPoint function fails to find the cross points?
