Adding Trend Line to the Series

Sky Zapper · Post by **Sky Zapper** » Fri Sep 08, 2006 9:06 am

I have a "Point" series plotted, I want to add a trendline to the series. The Teechart has the feature to add the "moving average" however, I require to plot the a "linear" trendline, the one similar to Excel.

I'm using C#.Net 2003 and TeeChart Pro Version 1.1.2004.16592

Hi Sky Zapper,

Trendline function was added in TeeChart for .NET v2. If you are interested in upgrading your current v1 license to v2 you can order it here. You can also contact our Sales Dept. at sales@steema.com for further information.

Can custom function help me out? The expression I would like to use is y=mx+c. I will provide the m and c values. x and y would be from the graph plotted.

Hi Sky Zapper,

Yes, you could try this as in the What's New?\Welcome!\New Functions\Custom y=f(x) example at the features demo, available at TeeChart's program group.
