[/chart]

Line Chart

[chart type="line" backgroundColors="#36A2EB, #FFCC66" title="Line Chart" xAxisTitle="xAxisTitle" ]

You can apply transparency to hexadecimal colors by appending 2 digits at the end which define the opacity of the color. This allows you to create more appealing line charts or colors. The list of hex codes are listed at the bottom of this README.
