How to Draw Area or Draw line in calculator 9850??
I have x and y volume. But dont know x y must put where, then how to make it draw line or area????

Lines can be drawn using either the Line command or the F-Line command. The Line command will draw a line between the last two plotted pixels, while the F-Line requires two points to be input in the command. The following examples do the exact same thing:

Plot 3,5
Plot 5,5
Line

F-Line 3,5,5,5

Which one to use depends on what you're going to use it for.

As for drawing an area, there's no command for that. It'd make life easier at times, but Casio wasn't designed for games in the first place.

Oh yeah, make sure your coordinate plane is viewable. CASIO graph calcs usually use a command on ViewWindow to do this. Another way is to go to Graph mode, press SHIFT and then press F3 (V-Window).

To fill in an area you will need two equations that describe the upper and lower boundries of the area to fill.

Now draw an y<= graph for the upper boundary,
Now draw a y>= graph for the lower boundary,

also on the graphs put the x-axis points to contain the area, an example: a simple square:

graph y<=2,[2,3]
graph y>=1,[2,3]

^^(i dont remember what the commands look like in programming mode)

This will fill in a square in between the x-axis points of 2->3, and in between the y-axis points of 1->2

This is also usefull to fill in areas in games as it can be easier/faster/require less code/more flexable than using lots of f-lines. Enjoy!
