how can i pass 2 arrays as datas in googlechart

Question

I'm using google charts easy php class (here's the link of it) and i want to draw Multiple Vertical Bar Chart, as the documentation says "Separate multiple data sets with |" so i try this , but nothing happens

 $chart1=new googleChart($a | $b ,'bary' );

*note that both $a & $b are arrays

i would appreciate any help :)

Answer 1

try $chart1=new googleChart(implode(',', $a).'|'.implode(',',$b) ,'bary' );

or see "CHART WITH 3 DIFFERENT DATA SETS" here http://code.google.com/p/googlechartseasyphpclass/wiki/Documentation where it creates an array with all your data arrays and then passes it to the Google Chart object with the smartDataLabel function
