I have a simple gnuplot question. I have a set of points (list of x,y,z values; irregularly spaced, i.e. no grid) that I want to plot. I want the plot to look like this:
- map view (no 3D view)
- color of each point should depend on z-value.
- I want to define my own color scale
- plot should... (1 Reply)
What does the term units mean in the context of server racks, for instance 4U? It is an indication of height, so does that mean the amount of disks the rack can hold or can the rack hold multiple motherboards / processors? (8 Replies)
Hi,
I am trying to arrange my graphs with GNUPLOT. Although it looked like simple at the beginning, I could not figure out an answer for the following: I want to change the style of my data points (not the line, just exact data points) The terminal assigns first + and then x to them but what I...

I was looking at the examples that show how to fit data using gnuplot (ex: gnuplot / misc (2E)) but I can't find a place that shows what to do if I have ranges for the x and y error bars. I tried the common sense:
gnuplot> fit f(x) "data.txt" using 3:6:4:5:7:8 via a,b

My input data has occasional holes in it, spots where a sensor couldn't be read. These are ERR in the data file instead of a floating point number. What should I change them to, for gnuplot to ignore these values instead of whining about them? (1 Reply)

UNITS(1) General Commands Manual UNITS(1)NAME
units - conversion program
SYNOPSIS
units [ -v ] [ file ]
DESCRIPTION
Units converts quantities expressed in various standard scales to their equivalents in other scales. It works interactively in this fash-
ion:
you have: inch
you want: cm
* 2.54
/ 0.393701
A quantity is specified as a multiplicative combination of units and floating point numbers. Operators have the following precedence:
+ - add and subtract
* / x -:- multiply and divide
catenation multiply
2 3 ^ exponentiation
| divide
( ... ) grouping
Most familiar units, abbreviations, and metric prefixes are recognized, together with a generous leavening of exotica and a few constants
of nature including:
pi,n ratio of circumference to diameter
c speed of light
e charge on an electron
g acceleration of gravity
force same as g
mole Avogadro's number
water pressure head per unit height of water
au astronomical unit
The is a unit of mass. Compound names are run together, e.g. British units that differ from their US counterparts are prefixed thus: Cur-
rency is denoted etc.
The complete list of units can be found in /lib/units. A file argument to units specifies a file to be used instead of /lib/units. The -v
flag causes units to print its entire database.
EXAMPLE
you have: 15 pounds force/in2
you want: atm
* 1.02069
/ .97973

BUGS
Since units does only multiplicative scale changes, it can convert Kelvin to Rankine but not Centigrade to Fahrenheit.
Currency conversions are only as accurate as the last time someone updated /lib/units.
