maybe you should choose another filename for the
output file, other than the name of the input file...
actually you are overwriting the input file.

[Gnuplot-info] autoscale in x1y1 and x1y2 axis

[goffart <Kla...@we...>]

Hi,

I'm trying to plot two sets of data into a histogram. The fist set has
values between 0 to 100, the second set has values between -100 to +100.
Each set has its own axis, the x1y1 and x1y2 axis. Autoscale scales the axis
independent, but I need the origin of both axis to be coupled. This means
the zero on the left should be on the same hight as the zero on the right.
Otherwise, the bars of the histogram start at different hight.

I can achieve that by plotting the data using just one axis, but extremly
small values in one data set and great values in the other one lead to
inacceptable results.


Is there a way to achieve what I want?

BR,

goffart

hello everybody, i've got a problem plotting data with gnuplot:
i want to plot data which are in the format "##,##" but i can't manage how
to tell gnuplot that the comma is not a separator but a decimal separator;
is there a way to do it?

[Gnuplot-info] Gnuplot3.7 help

[<sch...@UD...>]

I would be very grateful if you could help me.
I had been using gnuplot3.7 because it has hidden line removal in splot. I think that all newer versions have a bug in hidden3d.
Now I see that x11 is not an acceptable terminal type any more in gnuplot3.7. How do I get the
plot to display on the terminal screen?

Thanks very much.

[Gnuplot-info] Line plots

[Richard G. <rlg...@or...>]

I am trying to figure out how to change the line style for my plots, running
gnuplot on mac os-x.  I have tried several things, with nothing working so
far, so I am missing something obvious.  I tried putting
 gnuplot*line1Dashes: 42
in my .Xdefaults file and in my .gnuplot file , and have had no luck.  I am
running 
        G N U P L O T
        Version 4.2 patchlevel 3
        last modified Mar 2008
        System: Darwin 8.11.1

I am trying to get the line styles to be more distinct, so that small black
and white plots will be easier to understand than with what I get with the
default line types.

I have used things like:
   set style line 4 lt 4 lw 5 pt 6 ps 1
and it does not quite get me what I want.

Any hints would by appreciated.

Thanks,
Rich
   

[Gnuplot-info] Clipping a range of an axis

[mikpol <mik...@gm...>]

Hi,

I have time data spanning only a small fraction of a day, for example, from
2-4pm. I have such data for several consecutive days. When I plot this, the
actual data takes up a very small portions of the plot canvas, while most
space is taken by the straight lines connecting the last data point on day
N-1 to the first point on day N. I would like to clip those portions of the
x-axis so only the relevant time ranges 2-4pm are displayed, with small gaps
in between representing the rest of the day.

More generally, this corresponds to the following: I want to divide by axis
into several non-overlapping ranges, spanning the whole range of my data,
and then assign different scales to them. For the particular case described
above, this means dividing the time axis into two types of ranges: one
spanning 2-4pm and other spanning 4pm of day N-1 to 2pm of day N. I want to
keep the scale of the former normal, but make the scale of the latter very
small, so it takes up only a small portion of my graph.

Is this possible? Does anyone have any suggestions?

Any help is greatly appreciated!

Thanks.

[Gnuplot-info] problems loading data for contour display

[holle <hol...@ib...>]

Hello,
i'm having trouble loading a simple data file for displaying in gnuplot.
The data is a simple ramp with values from 0 to 1 and the file contains
50x200 values.
These values are not loaded correctly into gnuplot because i mainly see only
values between 0.2 and 0.8 and it is not a ramp!
Here you can see a screenshot of the plot:
http://www.nabble.com/file/p17364183/plot.jpg 

Please have someone a look at this easy sample and tell me what i am doing
wrong.
The data is here:  http://www.nabble.com/file/p17364183/rampe.dat rampe.dat 
and here is the .plt file i'm using for loading: 
http://www.nabble.com/file/p17364183/hanning.p1.xzres.plt
hanning.p1.xzres.plt 

thx a lot!
greetings from germany

Your strings (i.e. m_{10}) look like math, do you need to include $'s

[Gnuplot-info] 3D PLOTS ALWAYS HAVE A SQUARE BASE!! x_X

[swharden <swh...@gm...>]

Whenever I try to plot a 3d graph [splot "data.txt" matrix with lines], the
base of the graph is always a square.  My data is a matrix of 25 columns and
5 rows, so my base SHOULD be a rectangle.  How do I make gnuplot do this for
me???

Re: [Gnuplot-info] dashed line

[Thomas S. <t.s...@fz...>]

> Is it possible to plot a straight line like x=3,  1<y<2, without using "set

gnuplot is able to plot functions and data.
a vertical line isn't a function, but it may be plotted by giving its two
endpoints:

------------------------------------------------------------

set xrange [-pi:pi]
set yrange [-1.1:1.1]

# function plus
# 3 lines:
# from  3.0,-0.5 to  3.0,1.0
# from  2.0,-0.8 to  2.0,0.9
# from -1.0,-1.0 to -1.0,1.0

plot sin(x), "-" with lines
3.0 -0.5
3.0 1.0

2.0 -0.8
2.0 0.9

-1.0 -1.0
-1.0 1.0
e

Re: [Gnuplot-info] dashed line

[Thomas S. <t.s...@fz...>]

> Is it possible to plot a straight line like x=3,  1<y<2, without using "set

yes, in parametric plotting mode, see 'help parametric'

but then all of your functions need to be specified as a
pair of x(t),y(t)-functions, e.g.:

instead of:

set xrange [-pi:pi]
plot sin(x)

it would be:

set parametric
set trange [0:1]
f(x)=x*2.*pi-pi ; # just for convenience
plot f(t),sin(f(t))

plus a vertical line (x=2, -0.7<=y<=0.5):

plot f(t),sin(f(t)), 2.,t*1.2-0.7

I appreciate all the contributers to gnuplot.  Could some guru add a

the set of currently available "line and point types")?  If it is not proper
for public release, could I have a modified copy?  Many thanks.

Please note: Please kindly reply to my email address.  I am not subscribed
