How can I make a moving graph like a NT CPU usage history?

Hi experts!
How can I make a moving graph like a NT CPU usage history at NT task manager?

I can draw line at canvas but I have no idea like that.
The NT task manager's CPU usage history graph is moving
right to left and it keeps old cpu usage data.

Would help me step by step or would you tell me where is
free component?

The TChart component (which comes with Delphi 4 or is downloadable from Delphi Super Page) does moving charts as you describe.

There are teechart components for all versions of Delphi.

If you have Delphi3 you must have it if it's C/S or Prefesional edition... If it one of either two then look under the Active X tab in the palette. and you'll find TChart there,,,

Have a look at TGraph and TChartFx. They come with Delphi in the ActiveX component page.

Alternatively, here are some more from Delphi Super Page (use the search engine to find the filename):

grapheur.zip, piggraph.zip

Cheers,

Raymond.

Thanks rwilson and thanks for comment Viktor.

I found some free component at Torry's delphi page.
The component is Tloggraph and it looks like what I wanted.

THANKS!
HAVE A NICE DAY!!!
