A datasheet on the device would be a good start.

LCD's usually have an initialisation sequence.
Make sure the timing is correct as some LCD's need delays between the first few bytes to them.

Once the LCD is initialised you can set about drawing graphs and text on them.

On a purely graphic one you might need to design your own character set.
