I have a file with a number of matrices separated by a newline. I can plot any one of these matrices as a heatmap as shown in http://gnuplot.sourceforge.net/demo/heatmaps.html
However, now I would like to visualize all the matrices together on the same graph by plotting each matrix at increasing values of z, where each point is a coloured dot. I am trying to achieve something similar to the following question,
Plot 3D Grid Data as Heat Map using gnuplot
but without the cubes, as dots are sufficient.
This is the data for one matrix:

I am not sure if I understood correctly, but it seems that you want each matrix as a heatmap at a fixed (arbitrary) z-value.
As mentioned on the link you posted, making a plot like that one would require (at least to my knowledge) a lot of scrambling around on gnuplot. However, you could have a rough idea by doing:
set term png
set out "tmp.png"
set view 80,30
splot "tmp" matrix u 1:2:(2):3 w p pt 5 ps 0.75 pal,\
"tmp" matrix u 1:2:(1):3 w p pt 5 ps 0.75 pal,\
"tmp" matrix u 1:2:(0):3 w p pt 5 ps 0.75 pal
Which would give you:
Not pretty, but works. You'd have to play around with the labels, tics and view parameters depending on how many matrices you have. Hope it helps!
You could splot each matrix with image:
set ztics 1
set ticslevel 0
stats "data.dat" matrix nooutput
set xrange [-0.5:STATS_size_x - 0.5]
set yrange [-0.5:STATS_size_y - 0.5]
splot for [i=1:3] "data.dat" matrix using 1:2:(i):3 with image notitle
Or, depending on your need, you can also splot ... with pm3d:
set view 70,23
set ztics 1
set ticslevel 0
set pm3d interpolate 5,5
set autoscale xfix
set autoscale yfix
splot for [i=1:3] "data.dat" matrix using 1:2:(i):3 with pm3d notitle

I want to get a map using gnuplot like map1.
There are my code and part of the data.When I do set set timefmt "%Y/%m/%d/%h" set xdata time``set format x "%m/%d", it responded error in map2. I didn't know how to figure out it. Hope you can help me.
set style data lines
set style fill solid 1.00 noborder
set boxwidth 0.75 absolute

I'm not sure whether this question is fully answered.
I cleaned up your code a little. I don't know why you used \$2. If you put the below code into a text file and load this text file to gnuplot it should work.
Edit: to make the plot command a bit shorter and more clear you can:
define a function myTime(col) = timecolumn(col,myTimeFmt)
instead of filling the area between 2 curves, fill the area between a curve and the x-axis, but start with the upper curve.
why do you unset key? don't you want a legend?
Code:

I want to use gnuplot to do a log-log plot of the data using atomic units in the left y axys and using another units in the right y axys. Attemting to do so using the command:
p 'Freq_vs_Intensity_TDPT_AU.dat' u 1:2 w l, '' u 1:($2*3.51e16) w l axes x1y2
Produces two lines that are not superimposed as I want. How can I do this log-log plot?
should the rescaled column represent the same data expressed in different units, then there is probably no need to plot it twice. One could merely set the corresponding y2range and show the y2 axis, e.g.,
fac = 3.51e16
ymin = 1E-7
ymax = 1E5
set yr [ymin:ymax]
set y2r [ymin*fac:ymax*fac]
set ytics nomirror
set y2tics
p 'Freq_vs_Intensity_TDPT_AU.dat' u 1:2 w l
#, '' u 1:($2*3.51e16) w l axes x1y2
I have data recorded in time. But some data lines are missing and gnuplot replace them with long lines in these intervals.
How can i set gnuplot to draw nothing instead of draw lines in these intervals?
PS. I don't have free cells in these lines, I dont have these lines at all.
lines:
column 1 ... col 195
13:30:20.8 0.78061899
13:30:21.8 5.969546498
13:32:19.8 17.21257881
13:32:20.8 6.922475345
If you don't want to draw a line between two points you must insert an empty line in the data file between the two point entries, so that effectively you have
13:30:20.8 0.78061899
13:30:21.8 5.969546498
13:32:19.8 17.21257881
13:32:20.8 6.922475345
This cannot be done with gnuplot directly, but you can use e.g. awk to do the processing on-the-fly:
set timefmt '%H:%M:%S'
set xdata time
filename = 'data.txt'
plot 'awk ''{split($1,d,":"); t_prev = t; t = (d[1] * 60 + d[2])*60 + d[3]; if (t_prev && (t - t_prev > 10)) print ""; print }'' '.filename with lines
Here, the gap threshold is 10 seconds.
I suppose your miss data identifier is "NaN", then you can use the following command
plot "data" using 1:($2) with linespoints
instead of
plot "data" using 1:2 with linespoints
The former one will ignore the missing data and treat it as blank line and therefore not draw a connecting line across the gap while the latter one will draw continuous, unbroken line.
Just for the records: there are later questions about the same/similar issue.
Avoid connection of points when there is empty data
How to remove line between "jumping" values, in gnuplot?
Removing vertical lines due to sudden jumps in gnuplot
However, my solutions there require transparent color, which was not available in at the time of OP's question (gnuplot 4.6.5, Feb 2014). Nevertheless, there is a solution without external tools like awk or changing the data.
First solution for gnuplot 4.6.: Instead of a transparent line you use a white line which, however, will cover the grid lines, although it will be hardly visible.
Second solution for gnuplot 4.6 is using vectors. This really interrupts the line and will work for gnuplot 5.x as well.

The problem is, when I use
plot "lastframe.dat" using 1:2:3 with image t ''
I get the following error
warning: Number of pixels cannot be factored into integers matching grid. N = 60 K = 25
warning: Number of pixels cannot be factored into integers matching grid. N = 60 K = 25
Is there a way to plot using pm3d and get a color-map?
To get a color map using pm3d, try this:
set pm3d map
set dgrid3d
splot "lastframe.dat" using 1:2:3
Check out http://lowrank.net/gnuplot/plot3d-e.html for useful tips and tricks.
I use gnuplot to plot execution times measured on the CPU and GPU depending on the data size. So I have two files with the execution times in it. Plotting them is straight forward.
set title "CPU vs GPU"
set xlabel "Number of Particles (* 10'000)"
set ylabel "Time in Microseconds"
plot "cpuTimes.txt" title "CPU" with linespoints, \
"gpuTimes.txt" title "GPU" wit
The resulting plot can be found here: 1
I tried to use xtics however it doesn't shift the x-axis to start at 1 but just starts the ticks at 1. How can I shift the x-axis so it starts at 1 and ends at 50?

xtics are only to "label" the x-axis. What you are looking for is some sort of "data manipulation". I'd suggest making use of using like so:
plot "cpuTimes.txt" u ($0+1):1 t "CPU" w lp, \
"gpuTimes.txt" u ($0+1):1 t "GPU" w lp
To make the plot end at 50 there are two ways:
You could specify the x-range with set xrange [1:50] or with
plot [1:50] "cpuTimes.txt" u ($0+1):1 t "CPU" w lp, \
"gpuTimes.txt" u ($0+1):1 t "GPU" w lp
You need to include every like so:
plot "cpuTimes.txt" u ($0+1):1 every 1::::50 t "CPU" w lp, \
"gpuTimes.txt" u ($0+1):1 every 1::::50 t "GPU" w lp
See every for documentation for further reference.
I haven't used gnuplot in awhile, but I believe you can use set xrange to adjust what is plotted.
In your case the command is:
set xrange [ 1 : 50 ]
Give an axis range in your plot command:
plot [1:50] "cpuTimes.txt"
