i am working on showing data in a bar chart with chart.js
. my json response is already ready there but chart says its undefined values.
here is jquery with json
$(document).ready(function(){
$.ajax({
url: "<?php base_url();?>/charts/getsome",
method: "GET",
success: function(data) {
console.log(data);
var month = [];
var customers = [];
for(var i in data) {
month.push("Customer in" + data[i].apply_month);
customers.push(data[i].no_customers);
}
var chartdata = {
labels: month,
datasets : [
{
label: 'monthly customers',
backgroundColor: 'rgba(200, 200, 200, 0.75)',
borderColor: 'rgba(200, 200, 200, 0.75)',
hoverBackgroundColor: 'rgba(200, 200, 200, 1)',
hoverBorderColor: 'rgba(200, 200, 200, 1)',
data: customers
}
]
};
// alert(chartdata);
var ctx = $("#mycanvas");
var barGraph = new Chart(ctx, {
type: 'bar',
data: chartdata
});
},
error: function(data) {
console.log(data);
}
});
});
below is a snap for json response in console
And here is also a snap for chart with error
Please guide me where i am wrong. Thanks
You are getting response as a string. you should parse using JSON.parse(data)
success: function(data) {
console.log(data);
data = JSON.parse(data)
//the rest of your code
}
