ecopetition Posted September 8, 2010 Share Posted September 8, 2010 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 I'm hoping this pie chart can vary as pieces of data forming each wedge (and each fraction) change. Can anybody help with this? Thanks so much for your help. Quote Link to comment Share on other sites More sharing options...
