You need a special component to do this for you, if you don't want to code each dot of the graph by yourself directly to a canvas...

My Delphi 7 has a built-in DBChart componet on the DB control palette, drop one on your form, select it, and press F1 to know how to fill it with your data... or download one of the many free tee chart components out there if this one doesn't match your needs.
