I started off with this example: https://www.amcharts.com/demos/floating-bar-chart/ but want the floating-aspect also cover a date axis. This way I will be able to color a rectangular area in my charts.
I made the following changes:
Changed the x-axis to a date axis
Changed the y-axis to a value axis
Changed the data correspondingly
Changed the data-fields in the series-definition to use openValueXField, valueXField for the dates and openValueYField and valueYField for the values
Something (vertical colored lines) are displayed in the most left part of the chart but no colored areas.
When using values for both axes it works perfectly but not with dates. I hope some of you knows what is wrong here. The Amcharts Demo's only provide example with one axis.
The two source codes are included hereafter.

I try to bind a click event on symbol in a svg.
When a element spinns in the symbol, the click event is not fired, stops/pauses the animation, the click event fires.
How can i fix this, that the click events get fired every time i click on it, regardless if the animations run or not.

As written above, when the fans spin, no click fires.
Thanks for any advise.
I tried the code:
paper.rect(100, 100, 300,300).animate({transform :"t0,0r120t-0,0"}, 2000, "bounce");

And I'm sorry about all the Swedish comments, hope that dosen't matter for you to understand my code.
In this particular case you would need to get it to rotate around its center by specifying the centre points, so the transform would look like...
blueRect.animate({transform:"r120,60,45"}, 2000, "bounce")
If its variable where it will be, you could get the centre point from getBBox()

I need to use kinetic in order to transform one image using the anchors. I found this example:
http://www.html5canvastutorials.com/labs/html5-canvas-drag-and-drop-resize-and-invert-images/
I then need to save just one image - the yoda image (id: myImg) and send off to a web service. I'm having trouble with the saving portion.
Can anyone help? I'm not sure everything is correct, as I'm getting this error on when btnsave - Object #Class has no method 'replace' index.html:187

You might need to stringify everything,
For example:
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "/WS/SaveObject.asmx/fSaveToDB"),
data: JSON.stringify({ _obj: this }),
dataType: "json"
});
I had a huge problem before myself, started to work after i stringified it

Here I'm not sure about how to call the dojo code in enyo.
and
depends.js :
enyo.depends(
"source/charts1.js",
"lib/Chart2D.js",
"lib/widget/Chart2D.js",
"lib/blue.js",
"lib/dojo.js"
);
Now I'm getting the following errors :
error: Uncaught ReferenceError: dojo is not defined, Chart2D.js:1
[20110818-09:33:13.136736] error: Uncaught ReferenceError: dojo is not defined, widget/Chart2D.js:1
[20110818-09:33:13.138227] error: Uncaught ReferenceError: dojo is not defined, blue.js:1
[20110818-09:33:13.150707] error: Uncaught TypeError: Cannot read property 'graphs2' of undefined, index.html:10
It is working fine when I use it as a .HTML file with the same code in browser.
Chart.html :

Please help me in working with this in Enyo.
Thanking You.
Kind Regards,
Harry.
I don't think you have to modify the Dojo code. In Enyo, you have to tell the framework where it has to look for included JS files. Yo do so editing the depends.js file.
The index.html:
<!doctype html>
<html>
<head>
<title>Canvas Demo</title>
<script src="../../../../1.0/framework/enyo.js" type="text/javascript"></script>
</head>
<body>
<script type="text/javascript">
new enyo.Canon.graphs2().renderInto(document.body);
</script>
</body>
</html>
and depends.js:
enyo.depends(
"lib/dojo/dojo.js" ,
"source/charts1.js"
);
You'll have to copy everything Dojo needs to work (dojo, dojox, dijit) into lib, and check enyo paths.
I get a Dojo error when creating the new Chart2D object, and I'm not a Dojo expert to fix this. It's in the line:
var chart1 = new dojox.charting.Chart2D("simplechart");
I've modified your code:
enyo.kind({
name: "enyo.Canon.graphs2",
kind: enyo.Control,
components: [
{kind: "PageHeader", content: "bargraph"},
//{style: "padding: 10px", content: "Note: In the browser, you can press ctrl-~ to display the app menu."},
{kind: "Button", caption: "display graph", onclick: "displayGraph", flex: 1},
],
displayGraph: function() {
dojo.require('dojox.charting.Chart2D');
dojo.require('dojox.charting.widget.Chart2D');
dojo.require('dojox.charting.themes.PlotKit.green');
/* JSON information */
var json = {
January: [12999,14487,19803,15965,17290],
February: [14487,12999,15965,17290,19803],
March: [15965,17290,19803,12999,14487]
};
/* build pie chart data */
var chartData = [];
dojo.forEach(json['January'],function(item,i) {
chartData.push({ x: i, y: json['January'][i] });
});
/* resources are ready... */
dojo.ready(function() {
//create / swap data
var barData = [];
dojo.forEach(chartData,function(item) { barData.push({ x: item['y'], y: item['x'] }); });
var chart1 = new dojox.charting.Chart2D("simplechart"); // HERE IS THE PROBLEM
chart1.setTheme(dojox.charting.themes.PlotKit.green);
chart1.addAxis('x', { fixUpper: 'major', includeZero: false, min:0, max:6 });
chart1.addAxis('y', { vertical: true, fixLower: 'major', fixUpper: 'major' });
chart1.addPlot('default', {type: 'Columns', gap:5 });
chart1.addSeries('Visits For February', chartData, {});
var anim4b = new dojox.charting.action2d.Tooltip(chart1, 'default');
var anim4c = new dojox.charting.action2d.Shake(chart1,'default');
chart1.render();
// var legend4 = new dojox.charting.widget.Legend({ chart: chart1 }, 'legend3');
});
}
});
The object doesn't get instantiated. Got null pointer :-(
