I have a problem. My chart doesn't render at all.
this is the JSON data that the service is returning.
[{"label":"A","y":0},{"label":"B","y":5},{"label":"C","y":2},{"label":"D","y":0},{"label":"T","y":7}][{"label":"A","y":0},{"label":"B","y":5},{"label":"C","y":2},{"label":"D","y":0},{"label":"T","y":7}]
[{"label":"A","y":0},{"label":"B","y":10},{"label":"C","y":4},{"label":"D","y":0},{"label":"T","y":14}]
here is my code
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<script src="jquery/jquery-1.11.1.js"></script>
<script src="jquery/jquery.canvasjs.min.js"></script>
<script type='text/javascript'>
$(document).ready(function () {
$.getJSON('data.php', function (result) {
var chart = new CanvasJS.Chart('Container', {
title:{
text: 'Results of Survey',
},
data: [
{
type: 'column',
dataPoints: result
}
]
});
chart.render();
});
});
</script>
</head>
<body>
<div id="Container" style="width: 800px; height: 380px;"></div>

Your data is malformed. If you are trying to do multi-series, see this doc:
http://canvasjs.com/docs/charts/basics-of-creating-html5-chart/multi-series-charts/
This:
[{"label":"A","y":0},{"label":"B","y":5},{"label":"C","y":2},{"label":"D","y":0},{"label":"T","y":7}]
[{"label":"A","y":0},{"label":"B","y":5},{"label":"C","y":2},{"label":"D","y":0},{"label":"T","y":7}]
[{"label":"A","y":0},{"label":"B","y":10},{"label":"C","y":4},{"label":"D","y":0},{"label":"T","y":14}]
Should be:
[{"label":"A","y":0},{"label":"B","y":5},{"label":"C","y":2},{"label":"D","y":0},{"label":"T","y":7},{"label":"A","y":0},{"label":"B","y":5},{"label":"C","y":2},{"label":"D","y":0},{"label":"T","y":7},{"label":"A","y":0},{"label":"B","y":10},{"label":"C","y":4},{"label":"D","y":0},{"label":"T","y":14}]
You have repeating column labels though which is why I mentioned the docs above. Are you trying to do multiple series instead of a column chart?
Edit:
This code displays your data fine assuming you are doing a straight column chart:
<!DOCTYPE HTML>

I appreciate any and all help as I am very new to JS. I am trying to make a chart with 2 lines that have independent y-axes ranges so that one line doesn't look so flat. The data is from a CSV. The graphs are here: http://achouman-com.stackstaging.com/tester2-highcharts.html

The CSV looks like this. It's example data. The real data is millions of rows, so I can't hardcode the data in the code.

How can I make the second DIV into an on click event? I have both of them displaying right now. I want to display one then when you click it displays the second one and back and forth.
I have never used HTML or JavaScript before so bear with me.

If you want them to switch visibilities you should give them each a seperate id.
Then you will need to use javascript (jquery is an easy way to work with javascript)
The jquery code would look something like this
$('#div1').click(function(){
$('#div2').show();
$('#div1').hide();
});
$('#div2').click(function(){
$('#div1').show();
$('#div2').hide();
});
To use jquery get the library here: http://jquery.com/
If you don't want to use jquery here are simple show/hide functions:
<script>
function show(id) {
if(document.getElementById(id).style.display=='none') {
document.getElementById(id).style.display='block';
}
return false;
}
function hide(id) {
if(document.getElementById(id).style.display=='block') {
document.getElementById(id).style.display='none';
}
return false;
}
</script>
then just add those to your div onclick: <div id='div1' onclick='show("div2");hide("div1")'></div>
Ok if you want a div to be hidden when the page loads you can do (in jquery) $('#idOfDiv').hide() then to get the div to toggle you can do a $('#idOfDiv').toggle() Now if you want something to be an onClick even all you have to do is put it all in a
$("#secondDiv").hide();
$( "#firstDiv" ).click(function() {
$('#secondDiv').toggle();
});
$( "#secondDiv" ).click(function() {
$('#firstDiv').toggle();
});

In this code I am using jqplot plugin which I took from this site http://www.jqplot.com/deploy/dist/examples/line-charts.html. What I want is to change the size of height and width. How to do this ?

The size of the plot drawn depends of the dimensions of the container DIV, just change the CSS for width and height (instead of 600px and 250px).
<div id="chart1" style="width:600px; height:250px;"></div>
The width and height need to be specified for the container div itself.
Check out the source of the example.
<div id="chart1" style="height:300px; width:500px;"></div>
Ok, I've got a bar chart.
And it basically works... but the labels on the y-axis are kinda long and wrap and then run into each other.
I've tried changing the css, but it gets overidden by JS.
I tried scanning thru the jqplot library to find out where it happens but i got lost.
Any ideas? is there just an option i can set?

You could try this in your css:
.jqplot-yaxis {
margin-left:-80px !important;
width:80px !important;
}
