Ardu plot - plot arduino (serial) telemetry.

This processing sketch plots ASCII-encoded data from the serial port.

Format:

lines should begin with a 1 character command, followed by whitespace-delimited data

Only the "d" (data) command is required, so for a quick start, just print "d" followed by some numbers from your Arduino, separated by spaces.

serial commands:

####"d": data. numbers, float or int. all data must be on one line example: "d 1 2.5 3.6319982 0"

####"n": names. (optional) strings, in data order all names must be on one line note: re-send any range & pair data every time names are sent example: "n time rate bx by"

####"r": set range. (optional) name min max requires columns to be named include only the columns to be set to fixed range all data not set to a fixed range with this command will be auto-ranged multiple column ranges can be listed on the same line or with separate "r" commands on separate lines example: "r bx -5 5 by -5 5"

####"p": 2d pairs. (optional) pairs of x/y names to bind for 2-d plots. requires columns to be named multiple pairs can be listed on the same line or with separate "p" commands on separate lines example: "p bx by"

####"c": colors. (optional) rgb triplets (0-255) requires columns to be named multiple colors can be listed on the same line or with separate "c" commands on separate lines example: "c bx 255 0 0 by 0 255 0"

keyboard commands:

"r": print ranges.
"p": toggle pairs.
"n": toggle names.
"b": toggle background bars.
"a": toggle auto-ranging. (can be used to reset ranges)
ESC: quit.
