serializing data with google charts api
- by Patrick
I have the following google chart code that im working with as an example:
Type: Line
Dimensions: 270x150
283,285,295,204,340,#41C0E4
64,120,130,170,175,180,#3962C2
1,2,5,12,28,34,#005E91
Bottom Label: test
The following is the URL which generates the image below
http://chart.apis.google.com/chart?chs=270x150&cht=lc&chtt=&chd=s:zz1l9,LWXffg,AABCFG&chco=41C0E4,3962C2,005E91&chxl=0:|test|&chxt=x
My question is that i dont see the actual data in the url, but i see this
chd=s:zz1l9,LWXffg,AABCFG
That looks like serialized data, but im wondering how exactly that works, or how to encode/decode that to make the input of chart data dynamic via php.
