Yes, i have done something like that before: generating jpeg graphics
from data file.
For example, let says we are using the Android Serial Adapter to talk
to the Android phone or tablet. We can just build the jpeg image in "/
sdcard/DCIM/Camera", Many apps can display images there directly.
Since it is tricky to pass with standard input stream, we can build
everything in the command line.
/data/local/bin/edit /sdcard/DCIM/Camera/graph.dat create 0666
/data/local/bin/edit /sdcard/DCIM/Camera/graph.dat append x-axis TIME
/data/local/bin/edit /sdcard/DCIM/Camera/graph.dat append y-axis ECG
/data/local/bin/edit /sdcard/DCIM/Camera/graph.dat append 0 100
/data/local/bin/edit /sdcard/DCIM/Camera/graph.dat append 1 200
...
/data/local/bin/jped /sdcard/DCIM/Camera/graph.jpg from /sdcard/DCIM/
Camera/graph.dat
The adapter can also hookup an LCD or VGA monitor directly.

Bad benchmark as one would assume a "smart" display would have
commands like "fill region" (even if only "fill rectangle").
A better choice would be copying a full-screen bitmap to the
display (assuming you are interested in pixel write rate).
OTOH, the OP might find using a "draw polyline" more appropriate
for his application (ECG).

No. but I would like to know your through-put using a serial interface.
If you do go this route, but time how long it takes to fill the entire
screen with one color, then how long it take to fill the entire screen
with another color.
If you use async serial what baud rate ?
Thanks

Yes, that will work, but isn't it better to have single chip
integrated controller?
With the PIC24FJ256DA, you get 256K Flash, 96K SRAM, 16 channels A2D,
640x480 VGA, USB OTG. All that for $6 to $9 (qty 1).

Thank you everyone for your suggestions!
I took the cues for better searching on the web and found this, with an
integrated controller.

Looks good to me, but since I haven't worked with displays before I can't
be sure. Talking to the guys who make this, they say it should be
straightforward for my application of displaying medical waveforms.
Anyone used this before?

Yes, no PIC lower than PIC24.

I guess it depends.

What country or state are you in, to get this kind of service ?
I have heard about people having problems like this, but have not talked
to anyone that actually have been involved.

I'd never recommend a PIC to anyone after my last experience. Buggy C
compiler, buggy programmers, errors in documentation, reps who won't
return phone calls, long waits for tech support via e-mail. It's not
worth it.

Or get the $6 PIC24FJ256DA206, It comes with 16 bits graphic
controller.
