Javascript or PHP Charts/Graphs

I need a webpage that will do some basic math calculations and draw the results on a graph on the same page.? The attached excel sheet provides the calculations needed. Basically a person enters their weight and height the rest is calculated and plotted. This will be a better version of? a bmi calullator. For more info on BMI calculator click the link below. <[login to view URL]> Plain PHP will be fine. I just assumed that I need javascript. Below is what I have right. I basically want the code expanded. <SCRIPT LANGUAGE="JavaScript"> <!-- Begin function mod(div,base) { return [login to view URL](div - ([login to view URL](div/base)*base)); } function calcBmi() { var w = [login to view URL] * 1; var HeightFeetInt = [login to view URL] * 1; var HeightInchesInt = [login to view URL] * 1; HeightFeetConvert = HeightFeetInt * 12; h = HeightFeetConvert + HeightInchesInt; displaybmi =[login to view URL]((((w * 703) / (h * h)))*100)/100; var rvalue = true; if ( (w <= 35) || (w >= 900)? || (h <= 48) || (h >= 120) ) { alert ("Invalid data.? Please check and re-enter!"); rvalue = false; } if (rvalue) { if (HeightInchesInt > 11) { reminderinches = mod(HeightInchesInt,12); [login to view URL] = reminderinches; [login to view URL] = HeightFeetInt + ((HeightInchesInt - reminderinches)/12); [login to view URL] = displaybmi; } [login to view URL] = displaybmi; } return rvalue; } //? End --> </script> ## Deliverables This code will be used in multiple websites. Please include installation instructions. Basically I only want to copy code to my php file. I have no control on the server.? When you bid, please send me a link of previous job so that I can see how the final product will look like.? Contact me if you have any calculatiom (math)? questions.
