A new version of Plotr is out: version 0.1.4. A lot users asked me to implement a method that parses a table and plot a chart from the parsed data. So today I added it and it seems to work quite well. You can download the latest version at google project hosting. Here’s an example of the addTable function:

var options = {
	padding: {left: 30, right: 0, top: 10, bottom: 30},
	backgroundColor: '#dbdbdb',
	colorScheme: 'red'
};

/**
 * Plotr.Chart.addTable(table, xcol, yrow, xticks_row)
 * The upper left corner of the table is at (x=0, y=0).
 *
 * The following function call adds the data of element with id 'table'.
 * The data parsing starts at x=1 and y=1, so we avoid the headers. The
 * fourth argument is the row number of the row containing the labels
 * for the xticks.
 */

//initialize a new bar chart
var bar = new Plotr.BarChart('plotr1',options);
//parse the table and add is as a dataset
bar.addTable('table',1,1,0);
//render the barchart
bar.render();
