Timeline.js is a lightweight JS library to plot graphs using Timeline. As it uses Timeline, you can add event listeners on the plotted graph very easily.
I coded it because I couldn't find any basic JS library to do this, without any external dependencies and extra features. Timeline.js is only 13k once minified, and can be reduced under 10k with obfuscation. Better results may be obtained with a little refactor, but that's enough for me. Plus it can be very easily customised to fit your needs.
Then, you need to init the Timeline drawing, using `Timeline.init({'id': 'holder', 'height': '100%', 'width': '100%', 'grid': 'both', 'x_axis': true, 'rounded': false, 'x_callback': false});`. The arguments are all optional and are:
*`id` : the id of the parent element that will contain the Timeline
*`width` / `height` : width and height of the created Timeline
Then, you can add as many graphs as you want, with `Timeline.addGraph(NAME, COLOR);` where COLOR must be a valid CSS color.
And you can add points using `Timeline.addPoints(GRAPH_NAME, POINTS);`. Points is an array of point objects, which are of the type `{'x': ABSCISSA, 'y': ORDINATE, 'label': LABEL}`. LABEL is the text to display in the infobox when the mouse is over the point. You can use '%x' and '%y' in labels and they will be automatically replaced by the coordinates. You can also use `<sup>` and `<sub>` HTML tags. You can add another (optional) element `click` which must be a ffunction to bind to onclick event on this point.
_Note_ : You don't have to sort the points inside a same list of points in a Timeline.addGraph call. They will be sorted for you. But, if you call Timeline.addPoints multiple times, you must sort the points yourself between each call. The script won't do it for you and it will result in weird graphs if you don't do it.
