Using the lcd for drawing…

I apologize for such a basic question, I’ve searched through the PDF and Archive and cannot figure out how I can control messages being sent to the lcd in a particular order. It’s probably due to my background of programming in WinAPI, OpenGL and other API’s with graphic packages, so it’s possible the paradigm that I am trying to analyze it with is why I’m not getting it.

I want to:

Clear the background to a color (to erase previous image)
Draw a waveform (series of lines)
Draw a line
Draw a circle

If somehow I missed where this was, please point me in the right direction!

I believe what you are looking for is the trigger object.
It works wonders for sequencing events.
