Where is the trend function?

Hello all,

I'm searching for the Trend function in TeeChart for .Net, but I can't find. Isn't it there or has it another name?

In the case there's no Trend function like in the VCL version, has somebody created a custom trend function?

Regards,

Jaap

Hi.

The latest release does not include the trend function. However, we've already implemented it in the latest souces I'm testing here - trend (and many other functions) will be included in next major TeeChart .NET release (planned for early 2005).

Hi,

That's a pitty. I'm rebuilding an Intraweb Delphi 7 application in ASP.NET Delphi 8. In that Intraweb application I used the Trendfunction of the TeeChart VCL. The new version must be live in november.

Can you say if it's simple to create my own temporaly trendfunction. I have the source code of the VCL version? ((Or can I test your beta trendfunction

))

"Custom" functions are easy to derive in .NET – see:
Tutorial 7 - Working with Functions -> Deriving Custom Functions

You will already have the math in the VCL source.
