the values will show how, but i ran into another problem while trying to 
input the labels, labels need to be strings so I input them as an array 
such as the following: ["2014-07-28 14:24:11", "2014-07-28 14:24:11"] I 
saved it as a simple json in django and pass it to the webbrowser and then 
conver the json to a javascript value and pass that as the labels. Normally 
labels is ['sdfsdf','sdfsfs'] which is exactly how I pass mine Ive passed 
with "" and '' it doesn't matter. I'm trying to use the datetimes as the 
graph labels.


 
var dates = JSON.parse("{{ date_values }}");
var lineChartData = {

Re: I don't understand whats wrong with the way im passing django list to json

> Tom, I have done alot actually,


I have put the data into a json array, a list, a tupple, a dictionary. I 
have tried the following:
my data has been passed in every possible way I can think of. What I need 
to know how to do is convert a python list I pass with django to a 
javascript list because I believe that will correct the problem. Yes you 
are correct if I look at the second one [1,2,3,45,5] is how the data is 
ordered ie it is a list, however my data passes exactly the same.



var randomScalingFactor = function(){ return Math.round(Math.random()*100)};
var lineChartData = {
labels : ["1000","2000","3000","4000","5000","6000","7000", "8000", "9000", 
"1", "11000", "12000", "13000", "14000", "15000",],
datasets : [
{
label: "CPU Usage in MHZ",
fillColor : "rgba(220,220,220,0.2)",
strokeColor : "rgba(220,220,220,1)",
pointColor : "rgba(220,220,220,1)",
pointStrokeColor : "#fff",
pointHighlightFill : "#fff",
pointHighlightStroke : "rgba(220,220,220,1)",
data : [{{Json_data}}]
data : {{json_data}}
data : {{tupple_array}}
data : {{ list }}
data : [ {{tupple_data }} ]
data : [ {{ list }} ]

} 
]

}

window.onload = function(){
var ctx = document.getElementById("canvas").getContext("2d");
window.myLine = new Chart(ctx).Line(lineChartData, {
responsive: true
});
}

It doesn't seem like you have done much to debug this yet.

When you look at the generated javascript, does your "data" property
look the same type as the examples, or does it look different. Hint,
in your "My Second dataset", "data" is an array of values - is it an
array of values in "My First dataset".

Cheers

Tom
