Well, automake is gnu automake19 from the ports tree...

OK, I substituted make with gmake in the prepare script. There are a lot of=

warnings but it finishes now and I can build gnuplot. Seems to work.

Thanks for the hint,

That should be hint enough: your gnuplot was built without the PNG 
driver.  Build a new one that has it, and you'll be in the game.

You don't include the column in an equation, you apply a function to the 
data before plotting them.   Read "help using" attentively and you'll 
understand this example:

	plot 'data' using 1:(log($5/p0)*scale+h0)

This may be a good time to complain to the FreeBSD people about

This a problem with your make: it failed to substitute "$<" in the rule 
for building Makefile.am.in.  autoconf/automake is a little picky.  It 
expects people who use it to have a fully GNUified work setup, including 
a 'make' that is actually GNU make.  Our 'prepare' script makes similar 
requirements.

So: either you do your ./prepare runs on a Linux box, or you set up a 
completely GNUish environment for running it.

I'm working with a project at school and are struggling with a task in=20
Gnuplot. I don't know if it's possible.

I have an ASCII file with about 20 columns of numbers (one of those colum=

One of the columns is some thousand samples of barometric pressure as a r=

Re: [Gnuplot-info] Gnuplot and IP Audit Installation

[<as...@ib...>]

Hi Jules,

This is because you don't have installed the needed libraries.
In order to be able to generate png (and jpeg) files, you have to
install the GD library based PNG driver (observe you have to install
the assciated "dev" packages too). Try to install that first, and then
recompile gnuplot.
I hope this helps
Cheers

[Gnuplot-info] Gnuplot and IP Audit Installation

[Jules K. K. <jul...@ya...>]

Hi,


I have installed GNUplot 4.0 on a Linux system (Red
Hat Enterprise Operating System) to have generate
graphics for IP Audit software.
I am getting the message bellow from the IP Audit home
page: the image (png format) cannot be displayed,
because it contains errors.

The IP Audit shows the statistics of the network
usage, but it cannot displays the graphics.

When running GNUplot, it says that "terminal set to
unknown", if I set the terminal to png, it says
unknown or ambiguous terminal type.

I will appreciate your help.

Jules

[Gnuplot-info] pm3d map, splotting doubts

[Adonai H. M. <ado...@ce...>]

  Dear Gnuplot users,

I'm trying to use a pm3d map to plot the isotopic distribution as a 
function of atomic number (Z) and mass number (A).

I have three main doubts:

First.- I would like to assign the colours directly onto the integer 
values (centred in the values: Z,A), extending to half a unit up and 
down in both directions.
Currently, by using corners2colors {c1|c2|c3|c4} I can obtain the value 
of the crossing points in one of the intermediate regions, but never 
centred around the crossing point (which would be useful to read the 
value as a function of Z and A).

Second.- I would like to expand the x (A) axis in order to obtain square 
pixels (not the rectangular ones I get now). That is to set a one-to-one 
scale between both axis.

Three.- To force Gnuplot to create an output file (eps or png) which 
holds the whole picture! (currently, my eps is cutting the right boundary).

I also include the macro file I use.

Thank you very much in advance!

Is is possible to use the "with filledcurves" style

If not, any hint on how to produce the results

[Gnuplot-info] axis limits adjustment

[fly a. <vic...@gm...>]

Hi all.
I was wondering if there was a way to control axis limits adjustment. My
problem is that I want to use automatic adjustment, since I don't know what
the limits will be, but gnuplot seems to not like to do it smoothly. At
least with default settings (meaning no settings) it jumps from, let's say
in my example, 16 to 18 in the upper x-axis limit whereas the maximum x
value overpassed 16 by just 0.1 or so. This creates a gap between the plot
area and the right edge of the graph box, which just doesn't look cool.

Thanks.
Victor.

[Gnuplot-info] string concatenation?

[fly a. <vic...@gm...>]

Hi all.
Is there a way to do string concatenation in gnuplot?
I've got a file (file.name) whose name is then used to generate other
filenames like file.name.1, file.name.2, etc. I would be nice if I could
just do something like:
filename1 = filename + '.1' (instead of "+" something else could be used)

Of course I could pass all filenames as input parameters, but the # of
parameters is just 10 and there are so many other options to set:)
Thanks.

[Gnuplot-info] batch mode arguments and column numbers

[fly a. <vic...@gm...>]

Hi.
If I run a gnuplot script and pass some arguments to it, then I refer to
them as $0, $1 etc up to 10, right? 
But if I want to use functions, then when plotting I refer to column numbers
in a similar way. For ex.
sin_phi(x,y) = y/sqrt(x**2 + y**2)
cos_phi(x,y) = x/sqrt(x**2 + y**2)
vx(v2,v3,x,y) = - v2 * cos_phi(x,y) - v3*sin_phi(x,y)
vy(v2,v3,x,y) = - v2 * sin_phi(x,y) - v3*cos_phi(x,y)
v(v2,v3) = sqrt(v2**2 + v3**2)
coef = 1e-2
plot file_eqa every 2:2 u
9:10:(vx($5,$6,$9,$10)*coef):(vy($5,$6,$9,$10)*coef) with vectors head title
""

So now the question is: How do I do the same thing with functions when I use
gnuplot in batch mode? Because it seems to get confused with those.

Thanks.
Victor.

Well, a line usually doesn't do a very good job of filling an area 
(special plane-filling curves like the Hilbert and Peano fractals 
excluded).  But if you really have to, a spiral should work.  You won't 
get automatic tics, though:

	factor = 100  # adjust this
	sp_x(t) = t*cos(t/factor)
	sp_y(t) = t*sin(t/factor)
	plot 'file' u (sp_x($1)):(sp_y($1))

Only if your computer's C "double" type does.  Which almost certainly it 
won't.  So you'll have to preprocess them to fit them into a less insane
dynamic range.  Just divide them all by 1e1000 or so, or logarithmize them.

[Gnuplot-info] Plotting 1D-bar

Hi all,

I'm currently trying to find out a way to do a simple plot which it
turned out not to be so simple.
I want a 1d-plot, i.e., to plot some points along a given line. The
problem comes with the points. The points range from 0 to 10^1000 and
there are hundreds of points so I probably would need to have a big
image, filling an A4 page.

Is there any way to do this with gnuplot? If not, is there any other
software able to do this?

I think the problem I face with gnuplot is the range of the numbers,
right? Can gnuplot handle numbers that big?

First you have to decide which points you want to have marked differently.
If I understand you correctly, you want all data with a line, and every some
number (for ex. 4) of data points with a different mark - then use:
plot 'file' u 1:2 with lines, 'file' every 4 u 1:2 with points (or dots or
whatever)
Hope it helps.

If I do so, one of the most valuable advantages of gnuplot - speed - will be
negated :-( I use a script to generate 3x3 multiplot images - about 400
images at a time. So extra file input-output will likely slow it down.

Didn't make any difference.

I guess for now I'll just do without contours. But any help is still
appreciated if there IS a way to do what I want.

You'll probably have to write the contours to a "table" file first.

Setting pm3d to 'explicit', and "unset surface" may also help.

That's not very likely a good idea.  "set contour surface" is more 
likely to remain visible despite pm3d output being on the base, too.
