User (Legacy) Posted April 8, 2004 Report Share Posted April 8, 2004 My clients have asked me about trend lines but I am not sure what they are and if Chartfx supports them. Does Chartfx support them? Thanks Dan Reber Link to comment Share on other sites More sharing options...

Do some searching for "least squares linear regression" to see how it's done. Basically, you need to calculate the Y intercept and slope of the best fit line through your data points, and create a series that represents this line.

Software FX Posted April 9, 2004 Report Share Posted April 9, 2004 Statistical is only available for the .NET platform at this time. Another way you can do a trend line is by calculating it yourself and using an annotation object (Arrow) to draw it. You need to calculate the logical x,y position (in X and Y axis units) for the beginning and end of the line and then attach the annotation arrow to these points (ATTACH_ELASTIC). Check out the annotation extension docs. for details. -- FP Software FX, Inc. Link to comment Share on other sites More sharing options...
