In your example, the chd value is e:..LoLoLoot In their example, the chd value is t:60,40 So, e = encoded, t = text. So ... $imgBinary = file_get_contents('http://chart.apis.google.com/chart?cht=p3&chs=400x200&chdl=Work%7CEat%7CCommute%7CWatch%20TV%7CSleep&chdlp=r&chco=3399CC%2C80C65A%2CFF0000%2CFFCC33%2CBBCCED%2C3399CC%2C990066%2CFF9900&chd=e%3A..LoLoLoot'); or $imgBinary = file_get_contents('https://chart.googleapis.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World'); I've been playing with Google Maps and they document the polyline encoding algorithm fairly well. I'm sure they would have done the same for the chd ... and here it is http://code.google.com/apis/chart/docs/data_formats.html So.
