1.First install Ruby on Mac
Actually Ruby-1.8.7 is preinstalled on Mac OS X, so you no need to install.
Just run $ruby -v in your mac Terminal to check your ruby version:
2.Edit your ruby program file
You can use Textwrangler to edit, save your program file with .rb postfix
For example you create a file rubytest.rb under directory Document.
Inside rubytest.rb only include one line
puts "My first ruby program."
Then on your Terminal, you can run
$ruby Document/rubytest.rb
That's it, very simple.

Using Highcharts with CodeIgniter| The easiest way to draw chart
These days I'm doing CodeIgniter project, need chart library. I tried pChart, chartdirector,Highcharts etc.
I have to say Highcharts is the easiest to use, other tools like pChart, chartdirector need to write a extra library in CodeIgniter to use them,it's not convenient, but Highcharts no need.
Highcharts is a charting library written in pure JavaScript, all you need is down load Highcharts and jquery then put them into your CodeIgniter directory.
How to use? Look at here: http://www.highcharts.com/documentation/how-to-use

<script src="/js/jquery.js" type="text/javascript"></script> <script src="/js/highcharts.js" type="text/javascript"></script>
<script type="text/javascript">
var chart1; // globally available jQuery(document).ready(function() { chart = new Highcharts.Chart({ chart: { renderTo: 'container' }, title: { text: 'Combination chart' }, xAxis: { categories: ['Apples', 'Oranges', 'Pears', 'Bananas', 'Plums'] }, tooltip: { formatter: function() { var s; if (this.point.name) { // the pie chart s = ''+ this.point.name +': '+ this.y +' fruits'; } else { s = ''+ this.x +': '+ this.y; } return s; } }, labels: { items: [{ html: 'Total fruit consumption', style: { left: '40px', top: '8px', color: 'black' } }] }, series: [{ type: 'column', name: 'Jane', data: [3, 2, 1, 3, 4] }, { type: 'column', name: 'John', data: [2, 3, 5, 7, 6] }, { type: 'column', name: 'Joe', data: [4, 3, 3, 9, 0] }, { type: 'spline', name: 'Average', data: [3, 2.67, 3, 6.33, 3.33], marker: { lineWidth: 2, lineColor: Highcharts.getOptions().colors[3], fillColor: 'white' } }, { type: 'pie', name: 'Total consumption', data: [{ name: 'Jane', y: 13, color: '#4572A7' // Jane's color }, { name: 'John', y: 23, color: '#AA4643' // John's color }, { name: 'Joe', y: 19, color: '#89A54E' // Joe's color }], center: [100, 80], size: 100, showInLegend: false, dataLabels: { enabled: false } }] }); });
</script>
<div id="chartcontainer"></div>
The above script will draw a combination of column line pie chart like bellow.
