Steema teechart html5 Javazript change view area - teechart

How can I change the view area for a graph.
I have this example below se code an image
The left axes goes from 0 to 10 because there is data from 0 to 10 , but I still would like to show only 4 to 9, almost like its zoomed.
Is it possible ?

<script src="http://127.0.0.1/charts/js/teechart.js" type="text/javascript"> </script>
<script src="http://127.0.0.1/charts/js/teechart-extras.js" type="text/javascript"></script>
<script language="JavaScript">
function draw() {
var Chart1=new Tee.Chart("canvas");
Chart1.title.text="test";
Chart1.applyTheme("minimal");
Chart1.palette.colors[0] ="green";
Chart1.addSeries(new Tee.Line([]) );
var Series1 = Chart1.series.items[0];
Series1.marks.style="value";
Series1.marks.visible=true;
Series1.colorEach="no";
Series1.format.stroke.size=3;
Series1.pointer.visible=true;
Series1.data.values[0]=6;
Series1.data.labels[0] ="Okt";
Series1.data.values[1]=9;
Series1.data.labels[1] ="Nov";
Series1.data.values[2]=10;
Series1.data.labels[2] ="Dec";
Series1.data.values[3]=0;
Series1.data.labels[3] ="Jan";
Chart1.draw();Chart1.toImage("img");canvas.style.display="none";
}
</script>
<p>
<BODY onload="draw()">
<img id="img"><canvas id="canvas" width="800" height="400"></canvas>
</html>

You should do that manually setting axis minimum and maximum values, for example:
Chart1.axes.left.setMinMax(4,9);

D3 Dimple - How to show multiple dimple charts on same page?

I'm making an html page with several examples of charts that I will be using. On the page I have a Dimple line graph, a pie chart, a wordcloud etc. When I try to add a second dimple graph - this time a bar graph, the first dimple line graph that I already have on the page is drawn on top of my bar graph:
My HTML file looks like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>D3 Graphs</title>
<link rel="stylesheet" type="text/css" href="_/base.css">
<link rel="stylesheet" type="text/css" href="_/c3CSS.css">
<script type="text/javascript" src="_/d3.min.js"></script>
<script type="text/javascript" src="_/dimple.v2.1.0.min.js"></script>
<script type="text/javascript" src="_/c3.min.js"></script>
<script type="text/javascript" src="_/d3.layout.cloud.js"></script>
</head>
<body>
<div id="chartContainer">
<h1>Hot Topics Line</h1>
<script type="text/javascript" src=CurvyLine.js></script>
</div>
<h1>Hot Topics Pie</h1>
<div id="chart">
<script type="text/javascript" src=Pie.js></script>
</div>
<div id="wordCloud">
<h1>Clickable Word Cloud</h1>
<script type="text/javascript" src=WordCloud.js></script>
</div>
<div id="bar">
<h1>Clickable Word Cloud</h1>
<script type="text/javascript" src=WeekBar.js></script>
</div>
</body>
</html>
Without adding the bar chart at the end, the line graph displays properly at the top of the page above the pie chart. However, with the bar chart added, both the line and bar graph are drawn inside the "bar" div. Can anyone help with this please? Here is my line graph js file:
var svg = dimple.newSvg("#chartContainer", 590, 400);
d3.tsv("data/tweet_example.tsv", function (data) {
//data = dimple.filterData(data, "Owner", ["Aperture", "Black Mesa"])
var myChart = new dimple.chart(svg, data);
myChart.setBounds(60, 30, 505, 305);
var x = myChart.addCategoryAxis("x", "Month");
x.addOrderRule("Date");
myChart.addMeasureAxis("y", "Tweets");
var s = myChart.addSeries("Topic", dimple.plot.line);
s.interpolation = "cardinal";
myChart.addLegend(60, 10, 500, 20, "right");
myChart.draw();
});
and here is my bar graph js file:
var svg = dimple.newSvg("#bar", 800, 410);
d3.tsv("data/tweet_example2.tsv", function (data) {
//data = dimple.filterData(data, "Owner", ["Aperture", "Black Mesa"])
var barChart = new dimple.chart(svg, data);
barChart.addCategoryAxis("x", ["Day", "Topic"]);
barChart.addMeasureAxis("y", "Tweets");
barChart.addSeries("Topic", dimple.plot.bar);
barChart.addLegend(65, 10, 510, 20, "right");
barChart.draw();
barChart.draw();
});
Your problem is that you are using the same global name svg to hold references to two different charts. When your second piece of code runs, it overwrites the svg value that you had from the first piece of code, and when the .tsv() callback returns, it finds a reference to the second graph.
Simplest solution: use different names for svg variable in both pieces of code: svg1 and svg2 will be fine.
Most elegant solution: use some kind of namespace management, such as wrapping both pieces of code in immediately called functions:
function() {
// your first chunk of code here
}()
function() {
// your second chunk of code here
}()
This way you will have two svg variables local to their own scopes

Error in Kartograph.js

I'm using Kartograph.js to load svg map. But I get the following error when page loads:
Uncaught TypeError: Cannot read property 'getAttribute' of undefined
View.fromXML
Kartograph._mapLoaded
j
k.fireWith
x
b
Here is my Code:
<html>
<head>
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="raphael-min.js"></script>
<script type="text/javascript" src="kartograph.js"></script>
<script type="text/javascript">
function loadMap(){
var map = kartograph.map('#map', 600, 0);
map.loadMap('World.svg')
}
</script>
</head>
<body onLoad="loadMap()">
<div id="map"></div>
</body>
</html>
You need to define the metadata on the svg file.
For example:
<metadata><views><view h="604.816027229" padding="0" w="1000"><proj id="laea-usa" lat0="45" lon0="-100"/><bbox h="321.76" w="532.88" x="746.23" y="918.78"/></view></views></metadata>
If you created the svg with kartograph.py, you might need to add the layers added in the svg as follow:
function loadMap(){
var map = kartograph.map('#map', 600, 0);
map.loadMap('World.svg', function() {
map.addLayer('your_first_layer');
map.addLayer('your_second_layer');
});
}
To find the name of the layers to be added:
Open your svg file as text, for exemple in Firefox and use rightclick, page inspector.
On the second line you'll see : svg > g#something > ...
The name of one of the layer is the "something" after "g#". In the code it is the "id" of the "g" element.
Hope this might help you...

D3 example not working

I just copy pasted this from the first example in here:
http://www.recursion.org/d3-for-mere-mortals/
<!DOCTYPE html>
<meta charset="utf-8">
<body>
<!--<script src="d3/d3.v3.js"></script>-->
<script src="/d3/d3.v3.js"></script>
<div>
<script>
var rectDemo = d3.select("#rect-demo").
append("svg:svg").
attr("width", 400).
attr("height", 300);
rectDemo.append("svg:rect").
attr("x", 100).
attr("y", 100).
attr("height", 100).
attr("width", 200);
d3.selectAll("body").append(rectDemo) ;
</script>
</div>
</body>
and it shows nothing on the page. I am sure I am doing something stupid here but this is my first example and can't figure out what is going it....
The script attempts to draw the rectangle in a svg element that's added inside the (already existing) element with id="rect-demo".
Therefore, you need to have an HTML element (for example a <div>) with the appropriate id:
<div id="rect-demo"> </div>

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.

how to animate jqplot bar chart like example

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:
<html>

var s1 = [2, 6, 7, 10];
var ticks = ['a', 'b', 'c', 'd'];
plot1 = $.jqplot('chart1', [s1], {
// Only animate if we're not using excanvas (not in IE 7 or IE 8)..
animate: !$.jqplot.use_excanvas,

$('#chart1').bind('jqplotDataClick',
function (ev, seriesIndex, pointIndex, data) {
$('#info1').html('series: '+seriesIndex+', point: '+pointIndex+', data: '+data);
}
);
});
</script>

<div><span>Moused Over: </span><span id="info1">Nothing</span></div>
</body>
</html>
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.
