how to use JSON Data in chart.js?

Question

hi i have been trying to use data from MYSQL database and use them to create graphical chart with chart.js. i encoded data into JSON data( through a php file name data1.php), no

Answer 1

So this a JSON data example,

var data = '{"name":"tom","Second":"smith","age":"20","height":"180"}'

Create a Variable to Parse the data

var obj9 = JSON.parse(data);

Then make another Variable to store your specific data. (.age, this is relative to your data set, eg .name, .height)

var cat = obj9.age;

Then you can use the the variable cat in your graph data.

data : [cat9,randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor()]

Hope that helps.

I am not quite sure if you mean this:

var chartjsData = [];
for (var i = 0; i < json.length; i++) {
    chartjsData.push(json[i].present_worth);  
}
