This is the Plotr Configurator tool. Here you can configurate a chart by changing the values in the form on the left side of the page. After every change, the code to plot the chart is inserted in the dark-grey box at the bottom of the page. You can use the code to plot charts on your own pages (don't forget to include all javascript files).

Buy me a beer!

I recommend using Firefox to generate the code. Due to some IE incapabilities the generated options object has redundant key:value pairs.
