guff [-A] [-c] [-d WxH] [-f] [-h] [-l xyc]
[-m MODE] [-r] [-s|-b] [-S] [-x] [FILE]
guff reads a stream of points from a file / stdin and plots them.
Common options:
-
-d WxH: Set the dimensions (width and height). Should be formatted like "-d WxH", e.g. "-d 72x40" or "-d 640x480". -
-f: Flip X and Y axes in plot. -
-h: Print a help message. -
-l xyc: Set X, Y, and/or Count to log-scale. -
-m MODE: Set mode to dot (default), line (SVG only), or count (which tracks how densely clustered points are). -
-x: Treat the first column as the X value for the other columns. Otherwise, the row number is used for the X value.
SVG-only options:
-
-c: Use colorblind-safe default colors. -
-r: Draw a linear regression line for each column.
Rare options:
-
-A: Don't draw axes. -
-S: Disable stream mode (exit at first blank line).
Returns 0.
Read a series of number rows on stdin, and plot to ASCII once end-of-stream or a blank line is reached:
$ guffSame, but generate SVG and UTF-8 braille characters:
$ guff -s
$ guff -bRead number rows from a file:
$ guff filePlot stdin with a log-scale on the Y axis:
$ guff -lyTreat the first value on each line as the X value for all columns:
$ guff -xPlot stdin to SVG, with lines connecting the points:
$ guff -s -m lineSame, but using a colorblind-safe palette:
$ guff -s -c -m linePlot stdin to SVG, and draw a linear regression line for each column:
$ guff -s -rPlot stdin with point counts, to show point density:
$ guff -m countSame, with a log scale for the point counts:
$ guff -m count -lcSame, with SVG output:
$ guff -s -m count -lcThere isn't a way to change the plot options when a blank line resets the data.
Rather than attempt to intelligently handle strange input, guff just skips the rest of the line when strtod(3) indicates there isn't a well-formatted number.
