Hello, I’m trying to work out a method of displaying a pie chart depending on the values in an array by looping for a different value of $i, here’s what I have so far:
for($i = 0; $i < 11; $i++)
$colour = $i;
$fraction = ($pie_data[$i]/$total);
$pie_angle = $fraction*360;
ImageFilledArc($myImage, 100, 100, 200, 180, STARTANGLE, ENDANGLE, $colour, IMG_ARC_PIE);
As you can see I’ve got fractions, which I’m converting into an angle. However, I can’t think of a way to have the startangle and endangle parameters of the ImageFilledArc function depend on all of the previous pie angles, because currently the only thing I can do is have all of the wedges begin from the same angle, which does not look much like a pie chart. Can anybody help with this?
Thank you so much for your help, if any clarification is needed please tell me.
