[Gnuplot-info] How to stop gnuplot using Helvetica in eps files?

[Chris T. <C.T...@su...>]

Is there any way to stop using gnuplot from using Helvetica font for line
labels when generating eps (apart from editing the output!) This causes a
freeze-up when you try to place a gnuplot eps file in Illustrator. The only
workaround I know of at present is to open the file explicitly and copy and
paste but this is a bit of a pain.

[Gnuplot-info] How to plot each group of data points in a data file with different point style?

[Jun Y. <Jun...@ni...>]

Hi,

I am using Gnu Plot 4.0 under WindowsXP.
I want to plot each group of data points in a data file with different
point style, but I don't know how to.
I've seperated each group of data points with double blank lines
according to the manual, but it seems doesn't work.
Please somebody help!


Best Regards,

'set size ratio -1' is as much as you get.  If that does the trick, 
good. If not, sorry --- file a bug.

[Gnuplot-info] True scale isometric plots

[Alan B. <br...@co...>]

I am plotting a ray trace in 3D using splot.  Is there any simple way of
setting the three axes to the same scaling (units per inch) so that the
isometric view is not distorted except for the fact that it is an
isometric view.  I wish circles to be circles if viewed normal to the
plane they are in.

The cause of this probably is that you missed one important detail about 
gnuplot's mathematical expression syntax: just like C, it distinguishes 
between integers and floating-point numbers.  See "help expressions"

All your 'a' values are integers, and several of the constants used in 
the equations are, too.  In particular 60/a is not what you might think 
it is, if 'a' is an integer.  Your example boils down to this:

gnuplot> a=100
gnuplot> print 60*pi/a
1.88495559215388
gnuplot> print 60/a*pi
0.0

Depends on what you mean by "make a histogram".   There are two rather 
distinct things people refer two by this phrase:  binning & counting 
data into a histogram dataset, and displaying such a dataset as a plot.
gnuplot, by its nature, is really only meant to do the second part. 
Following the old Unix dogma of "one tool <--> one task", binning and 
counting is not gnuplot's job.  But it does offer rudimentary support 
for it, as of version 4.0:

	bin(x,width) = width * floor(x / width)
	plot 'data' using (bin($1,5):(1.0) smooth frequency with histeps

[Gnuplot-info] Problem of Interpretation

[<r....@ma...>]

Hi Team,

I write you let you know that Gnuplot seems to have a problem of  
interpreting mathematical expressions.

Here is the version used: Version 4.0 patchlevel 0, last modified Thu  
Apr 15 14:44:22 CEST 2004 (System: Darwin 8.6.0) Hereafter, both two  
equations (as per the plot command line) are identical but written in  
the different way.

Results depends on the location of parameter "a" in the plot command  
line. It turns out to be that the 1st plot is right, but the second  
plot (just the same equation but written differently) is wrong.

Is it a known problem?

Regards,

Raf

Not really.  The problem here is that gnuplot's "fit" command is 
designed to fit data to analytic models, i.e. those representable as a 
user-defined function in gnuplot.  You're trying to fit data to data.

You will have to look for a tool matching that job elsewhere. 
Octave/Matlab probably have something, as will most software packages 
dedicated to heavy-duty data processing.  gnuplot is not one of them.

[Gnuplot-info] Different behaviour of palette in X11, postscript and png terminals

[Mike B. <mi...@mb...>]

Hi,

I have encountered some unexpected behaviour in gnuplot while trying to 
produce a surface plot using 'splot' and a particular grayscale palette. 
The plot that I'm trying to generate involves the aspect (or azimuth) 
angles of land surface slopes in a digital terrain model. These angles 
run from 0 degrees (north), through 180 degrees (south), to 360 degrees 
(north again). Therefore, the palette that I want to use ideally needs 
to run from black (0 degrees) to white (180 degrees) to black again (360 
degrees). The problem that I have with the grayscale palette is best 
illustrated by the following commands, which gives the output exactly as 
required in an X11 terminal...

set term x11
set palette gray rgbformulae -13,-13,-13
test palette

(a screenshot of the resulting output is attached; test_palette.png).

However, when I try to produce the same thing using either the epslatex 
terminal (my preferred format) or the postscript terminal, i.e.

set term epslatex  "default" 10
set palette gray rgbformulae -13,-13,-13
set output "test.eps"
test palette
set output

the output grayscale seems to revert to simple black (0 degrees) through 
to white (360 degrees).

Hmm! So, am I doing something wrong? do the rgbformulae in fact vary 
from one terminal type to another? is this a limitation of postscript 
graphics? or is it a bug in gnuplot?

Even more curiously, when I tried to output the same figure directly as 
a PNG image (as opposed to via a screen grab) using the following commands

set term png
set palette gray rgbformulae -13,-13,-13
set output "test.png"
test palette
set output

I don't get the grayscale wedge at the bottom of the image at all.

For the record, this is the output of 'show version' on my system.
