If your talking about built in AFL functions like PlotOHLC() etc then they have built in abilities to plot beyond the end of the last bar... so wondering about how much space in there is not something you have to worry about.
If it's low level gfx, then I'm not sure I can help. I do use low level gfx quite a bit but it is either 'on or off' my chart... I tend to use it for display buttons & grids etc..etc...
There may well be a way to get back the info you want... maybe someone else can point you in the right direction...?
As a point of note Conrad, I wouldn't worry so much about code speed right now... my advice is to get down what you want, then worry about removing any superfluous calculation afterwards...
