I would like to plot a 3D picture from data (below). All axis should have equal scale. However resulting picture is too small relative to canvas size.
How can I fill most canvas with the plot?
I tried changing canvas size, or setting size 1,1.
Data (5 squares):

I am using gnuplot 4.4 patchlevel 3,
commands:
set term pdfcairo size 2,1;
set xrange [-1.05:1.05];
set yrange [-0.05:1.05];
set zrange [-0.05:1.05];
unset key; unset border; unset tics;
set lmargin 0; set rmargin 0; set tmargin 0; set bmargin 0;
set view equal xyz;
set output 'address';
splot 'data.txt' w l;
unset output;
Thank you.
The "set view" command contains two scale factors. The first scale factor scaless the entire plot, the second one scale the z axis only.
Syntax:
set view <rot_x>{,{<rot_z>}{,{<scale>}{,<scale_z>}}}
The easiest way to adjust this is using an interactive terminal. Click and drag with the middle mouse button to adjust the scale factors to taste. Then use show view to note the current values. Add those to your script. For example to scale the whole thing by a factor of two:
set view ,,2.0

I am trying to plot the graph using gnuplot, but I am getting strange result. gnuplot for some reason makes larger gaps at two dates and places January 29th over January 31. The commands I use:
set terminal pngcairo size 1600,800 enhanced font "Helvetica,16"
set output 'Pic.png'
set timefmt '%Y-%m-%d %H:%M:%S'
set xdata time
set format x '%Y-%m-%d %H:%M:%S'
set title "Title"
set xlabel "Date"
set ylabel "Level"
set xtics timedate
set xtics rotate
nth(countCol,labelCol,n) = ((int(column(countCol)) % n == 0) ? stringcolumn(labelCol) : "")
plot 'data.txt' using 1:6:xtic(1) with l title 'V' lw 3, \
'data.txt' using 1:2 with l title 'D' lw 3, \
'data.txt' using 1:3 with l title 'H' lw 3
Output:
Note - nth is just for fun - I tried to get the xtick at every nth date, but failed.
Behaviour is the same with gnuplot 5.0.3/64 and 5.2.2/64 on linux (I can provide the data file - do not see it fit to post 60 lines of data I use)

How can one set different heights for two or more plots in multiplot-mode using set size <x>,<y> respecting correct arrangement for the x-axes of the plots? Following problem: I've got a heatmap plot and another linespoint plot with the same time axis. The heatmap plot contains way more information and should use e.g. 80% of the canvas height. Using
set multiplot layout 2,1 margins .1,.8,.05,.95 spacing .05
sets the plots in perfect arrangement but without the possibility to change heights; or at least I didn't manage to get it right. Here are two examples using code from the gnuplot demopage:
$map2 << EOD
0 0 5
0 1 4
0 2 3
0 3 1
0 4 0
1 0 2
1 1 2

4 4 3
EOD
set multiplot layout 2,1 margins .1,.8,.05,.95 spacing .05
plot '$map2' using 2:1:3 with image
plot sin(x)*cos(x)**2, tan(x)
unset multiplot
which results:
Setting explicit sizes and origins before the plotting commands doesn't have any effect.
Plotting without the margins/spacing option and instead setting explicit sizes and origins for each plot one could only guess the correct x-width for the second plot. Guessing it between .85 and .9 in the code:
$map2 << EOD

plot '$map2' using 2:1:3 with image
set size .85,.25 # <---
set origin 0.025,0
plot sin(x)*cos(x)**2, tan(x)
unset multiplot
lets me plot it like that:
I hope I could explain my question and thanks a lot for your help! It is highly appreciated!
If I have understood your question, you have to only change rmargin and lmargin:
set size 1,1
set origin 0,0
unset bmargin, unset lmargin, unset tmargin, unset rmargin
set multiplot
set size 1,0.8
set origin 0,0.2
set lmargin at screen 0.1
set tmargin at screen 0.95
set rmargin at screen 0.9
plot 'map2.dat' using 2:1:3 with image
set size 1,0.2
set origin 0,0
set tmargin 0
set lmargin at screen 0.1
set bmargin at screen 0.1
set rmargin at screen 0.9
plot[GPVAL_X_MIN:GPVAL_X_MAX] sin(x)*cos(x)**2, tan(x)
unset multiplot
This question was answered partly in couple of places, like Create a gif in Gnuplot from a single file.
Yet there is a problem, the provided answer is going to plot only points at each index.
lets say I have the following data set:
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 1 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
my code for creating the gif is :
set terminal gif animate delay 50
set output 'foobar.gif'
set style line 1 lc rgb '#0060ad' lt 1 lw 2 pt 7 ps 1.5
stats 'Datafile' nooutput
do for [i=1:int(STATS_blocks)] {
splot 'Datafile' index (i-1) matrix with p ls 1
}
This code will generate a gif that just contains the data of each index. while I want the second dataset to be added to the first one the animation.
How should I do that?
Well I managed to find the answer by my own, and sorry #Christoph the easiest answer is always erasing the question. Yes it is possible with adding a second loop. I knew that I needed to add a second loop, but I was not sure how to:
set terminal gif animate delay 50
set output 'foobar.gif'
set grid
set style line 1 lc rgb '#0060ad' lt 1 lw 2 pt 7 ps 1.5
stats 'Datafile' nooutput
set ztics 1
set zrange [-2:7]
do for [i=1:int(STATS_blocks)] {
splot for [j=1:i] 'Datafile' index (j-1) matrix notitle with p ls 1
}
This will generate what I want.
My data file is a 9800x128 matrix of floating point values, and I'm having trouble plotting a surface graph, that should look similar to MATLABs surf() plot.
Using:
splot '/directory/data.txt' every ::1:1 matrix with lines
works fine, but everything is in one color which makes it impossible to see what's going on. The color palette that I've imported is:
set palette defined (0 0 0 0.5, 1 0 0 1, 2 0 0.5 1, 3 0 1 1, 4 0.5 1 0.5, 5 1 1 0, 6 1 0.5 0, 7 1 0 0, 8 0.5 0 0)
Which is similar to the default one used in MATLAB. Drawing just a 2D contour using this palette:
plot '/directory/data.txt' matrix notitle with image
works just fine as well, it's as soon as I try to marry the color map with a surface plots, as follows:
splot '/directory/data.txt' every ::1:1 matrix with image
I get the following warning message and I'm left with an empty plot.
warning: Number of pixels cannot be factored into integers matching grid. N = 1244473 K = 762
If your data is saved as matrix format, i.e. arranged as
z00 z10 z20 z30 ...
z01 z11 z21 z31 ...
z02 z12 z22 z32 ...
z03 z13 z23 z33 ...
...
then you can plot you data with
set palette defined (0 0 0 0.5, 1 0 0 1, 2 0 0.5 1, 3 0 1 1, 4 0.5 1 0.5, 5 1 1 0, 6 1 0.5 0, 7 1 0 0, 8 0.5 0 0)
splot 'data.txt' matrix with pm3d
I have the below gnuplot script, I'm trying to display the third column when the mouse hover over a point of the plot.
set title "Cloud"
set xlabel "Date"
set ylabel "Number"
filename ='data.dat'
stats filename using 4 nooutput
set xdata time
set timefmt '%Y-%m-%d'
set format x '%Y'
rand_x(x) = x + 60*60*24*7 * (rand(0) - 0.5)
rand_y(y) = y + (rand(0) - 0.5)
set xrange [ "1995-01-19":"2013-12-12" ]
plot for [i=0:int(STATS_max)-1] filename \
using (rand_x(timecolumn(1))):(i < $4 ? rand_y($2) : 1/0):3 pointtype 7 linecolor palette notitle
u 0:1:2 with labels hypertext point pt 7 ps var lc rgb "#ffee99"
And the data file looks like below:
1999-01-19 21 0 1
2009-07-01 0 1 1
2008-08-20 2 1 1
2008-12-18 1 1 1
2004-05-12 4 1 1
2009-07-29 2 1 1
2008-08-07 0 1 1
2006-03-08 1 1 1
2004-08-31 9 1 1
2001-03-27 12 1 1
2009-08-19 0 1 1

2009-11-11 0 1 1

2012-02-22 0 1 1
2011-05-11 0 1 1
2011-03-03 0 1 1

2011-10-05 0 2 1
2013-01-09 0 2 1
2011-06-03 0 2 1
So can you please tell me what's wrong with my script?
Thanks.
First a remark for the readers: hypertext works only with the 4.7 development version.
To your problem: For plotting the labels, you must also use the same x and y columns 1 and 2 (you use 0 and 1). And you need the third column for the labels and a fourth one for the ps var. So your plot part for the labels is:
plot for [i=0:int(STATS_max)-1] filename \
using (rand_x(timecolumn(1))):(i < $4 ? rand_y($2) : 1/0):3 pointtype 7 linecolor palette notitle,\
'' u 1:2:3:3 with labels hypertext point pt 7 ps var lc rgb "#ffee99"
