I’ve managed to code my first heart-rate graphic. And it’s CUTE!
By looping through the big data file I can isolate the heart-beats, take the different values to draw lines and put in the dots at the right coordinates. The next step is to draw a big graph in Flash and move it to the right at certain intervals (500 milliseconds for example). Now it still is a drawing that is animated from left to right. It disappears from view after a while, as you can see in the picture.
