Not sure why following code (basically a cut & paste from example) is returning error.
var textWhy = new THREE.TextGeometry( "Why", { size: 10, height: 5, curveSegments: 6, font: "helvetiker", weight: "normal", style: "bold" });
Cannot read property 'normal' of undefined
I am new to webgl, hope someone can point me to a solution.
Thanks.
Tried with this simplest snippet. Result is the same.
<html>
<head>
<title>Three.js Why Text</title>
<script src="typeface-0.15.js"></script>
<script src="helvetiker_regular.typeface.js"></script>
<script src="helvetiker_bold.typeface.js"></script>
<script type="text/javascript" src="Three.min.js"></script>
<script type="text/javascript" src="jquery-1.7.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
textWhy = new THREE.TextGeometry( "Why", { size: 10, height: 5, curveSegments: 6, font: "helvetiker", weight: "normal", style: "normal" });
});
</script>
</head>
<body>
</body>
</html>
Found that I should not use "typeface-0.15.js" but only the font helvetiker_*.typeface.js. The 'load' function is provided in Three.js. So it should be:
<html>
<head>
<title>Three.js Why Text</title>
<script type="text/javascript" src="Three.min.js"></script>
<script src="helvetiker_regular.typeface.js"></script>
<script src="helvetiker_bold.typeface.js"></script>

this code is working now..
I am not able to find the tickOption for dateAxisRenderer.
I've tried it in the following way:
axes:{
axesDefaults:{tickRenderer : $.jqplot.CanvasAxisTickRenderer, tickOptions :{angle: -30}},
xaxis:{
renderer: $.jqplot.DateAxisRenderer,
tickOptions:{
angle: -30,
formatString:'%H:%M'
},
}
}
but this din't seem to work. Can someone please help me with this.
You need to add rendererOptions: {tickRenderer: $.jqplot.CanvasAxisTickRenderer} in xaxis definition :
axes:{
axesDefaults:{
tickRenderer : $.jqplot.CanvasAxisTickRenderer,
tickOptions :{angle: -30}
},
xaxis:{
renderer:$.jqplot.DateAxisRenderer,
rendererOptions:{
tickRenderer:$.jqplot.CanvasAxisTickRenderer
},
ticks: xTicks,
tickOptions: {
angle: -30,
formatString: '%H:%M'
},
}
}
Please see working example here

The File helloworld.pdf is in the same folder as the view, but when I run the project nothing gets rendered, just a small rectangle. Have I missed something? Any special considerations? Thanks for any help.
Figured it out eventually. What an awesome library PDF.js is.
I've taken the liberty of creating a sample MVC3 project using PDF.js. It follows 90% of the PDF.js demo on github, except a tiny, self explanatory (explained in the comments in the code) change in assigning PDF file paths to the viewer.
my json file looks like
{"items":[

I am getting uncaught exception- No data error
Before plotting the chart, I am printing the array and there are all the values that I need.
What is missing? Where am I doing wrong?
Thanks for your help.
I don't understand why you are feeding data to the objArrayData array in the way you are doing here. The data doesn't become an array just because there are square brackets surrounding them (it will only appear pretty and satisfying and confusing in the cosole.log).
Use array.push() instead of the way you are doing it here.
And also make sure you make the data.scoreAverage a number before parsing it to the array.
You can do it using parseFloat() function.
So finally you can feed the data to the array like this.
objArrayData.push([data.date,parseFloat(data.scoreAverage)]);
Here's the modified working code.

Hope this helps.
PS: Make sure you learn about arrays a little more.
Has anyone had any luck with this?
I copied and pasted the exact example code here http://www.jqplot.com/deploy/dist/examples/barTest.html into my text editor. I added all the .js files and .css file required. when I run the page in any browser, I am not seeing the bars or the animation. I have looked at the source code on the above URL as well to see how it works. Could someone tell me why I can the animated bar chart on the URL but not from my desktop? What's different? Here is the exact code I copied:

here is what I see in the browser after running that code:
Thanks
For anyone interested, I've found the answer. The example code taken from the barchart.html page in my post doesn't appear to need the conditional syntax (below) in order to animate the bars:
$.jqplot.config.enablePlugins = true;
// Only animate if we're not using excanvas (not in IE 7 or IE 8)..
animate: !$.jqplot.use_excanvas,
From the animate example on the examples page , the following code will do the trick:
animate: true,
// Will animate plot on calls to plot1.replot({resetAxes:true})
animateReplot: true,
I read the entire documentation and was doing a lot of playing around with the code. Eventually, I got to the full "examples" page (not the few listed on the tests and examples page which I initially viewed since it was listed first in the documentation). I really wanted to understand the plugin code since the developer took so much time to really provide a ton of info, comments and updates to his code base.
