I've checked the other similar questions, but still can't track down the source of this problem.
Here's the code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="resources/jquery/jquery.jqplot.js"></script>
<link rel="stylesheet" type="text/css" href="resources/jquery/jquery.jqplot.css" />
</head>
<body>
<div id="chart2" style="height:300px;width:500px; "></div>
</body>
<script type='text/javascript'>
$(document).ready(function() {
var line1 = [['Nissan', 4],['Porche', 6],['Acura', 2],['Aston Martin', 5],['Rolls Royce', 6]];
$('#chart2').jqplot([line1], {
title:'Bar Chart with Varying Colors',
seriesDefaults:{
renderer:$.jqplot.BarRenderer,
rendererOptions: {
// Set the varyBarColor option to true to use different colors for each bar.
// The default series colors are used.
varyBarColor: true
}
},
axes:{
xaxis:{
renderer: $.jqplot.CategoryAxisRenderer
}
}
});
});
</script>
</html>
The problem is, nothing displays other than the chart canvas. There are no errors logged in the console, and the source files were loaded. I moved the call the .jqplot to below the chart2 div because a user believed this was necessary, though I don't believe that to be the case since we're using $(document).ready(function()...
Any idea where the problem lies?
Resolved.
Needed to include the additional renderers which had been specified in the call the .jqplot.

<script type="text/javascript" src="resources/jquery/plugins/jqplot.categoryAxisRenderer.js"></script>

I am developing a Radial Gauge and I need to add dynamic data to it. The following is the code that i have done with dynamic data. Can some one help me with it to add dynamic data. My code example is given below.
var arrGauge_360 = [
{key:"data-type",value:"radial-gauge"},
{key:"data-width",value:"400"},
{key:"data-height",value:"400"},
{key:"data-max-value",value:"100"},
{key:"data-value",value:"50"}, //this value has to be dynamic. not a static data.
{key:"data-animate-on-init",value:"true"},
{key:"data-major-ticks",value:"0,20,40,60,80,100"},
];
function myFunction_gauge_360(){
debugger
$("#gauge_360").append("<canvas id='ht_gauge_360'></canvas>");
arrGauge_360.forEach(function(item,index){
debugger
$("#ht_gauge_360").attr(item.key,item.value);
});
};

I am trying to make my Dygraphs graph resizable, and to add to the page a button where one can choose if the graph has to be linear or logarithmic. The examples are both described in the Dygraphs documentation page (respectively here and here), but I don't know how to implement the changes in my html code. Do you know how could I do it? Javascript illiterate here.

g2 = new Dygraph(
document.getElementById("graphdiv"),
"combined_file.csv", // path to CSV file
{ title: 'Title',
xlabel: 'Time',
ylabel: 'Space',
legend: 'always',
labelsDivStyles: {'textAlign': 'right'},
});

I am trying to render the Y-axis label rotated 90 degree. Quoting the jqplot example
By including the "jqplot.canvasTextRenderer.min.js" and "jqplot.canvasAxisLabelRenderer.min.js" plugins, you can render label text directly onto canvas elements.
Here is the error i get from Firebug
TypeError: a.jqplot.CanvasFontRenderer is not a constructor
Here is my whole code

var plot1 = $.jqplot('chart', [cosPoints], {

},
yaxis:{

});
});
I am clueless, I don't understand what I am doing wrong since I am following the basic tutorial of this API. Thank you for your time
match your text renderer file with the file from this link: jqplot.com/deploy/dist/plugins/jqplot.canvasTextRenderer.js
I think this is the correct file and it has the jqplot.CanvasFontRenderer inside it. Maybe your file doesn't have that
I am trying to display bar chart using jqPlot bar chart. I have doing code which display chart in Internet Explorer. But for same code chart does not displayed in Crome and Mozilla browser.

Why this code does not work for Crome and Mozilla browser?
I was able to get the graph displaying in IE9, FF and Chrome by:
Removing the <style> tag. This tag prevented anything displaying in all browsers.
Adding <!DOCTYPE html> at the top of the file. This prevented an error in IE9.
Also, the way you are linking to json2.js is actually retrieving the Github page that displays the file, not the actual file itself.
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 can see here:
Here is my html file:

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