I want to know how can I plot this type of graph to compare experimental data.
Appreciate
A line code for gnuplot

I have a dataset that has x,y,z columns. I have created surface plot using gnuplot and contour on top and bottom as see below. Here is the dataset: https://www.dropbox.com/s/8evj5da7yco1xmo/datx.dat?dl=0
Below is the plot from the data in the link.
I'm trying to create a contour plot like the one below with contours on the side, how do I accomplish this in gnuplot?
Here is the solution http://gnuplot-tricks.blogspot.com/2010/ but I'm unable to replicate it for my dataset.
I am exporting the 3D plot data from Mathematica and trying to plot it in gnuplot. I would like to put color gradient like we do in pm3d. But the constraint of pm3d is that we need a space each time when there is a sign change. Since I have a large collection of points and the format of the Mathematica output is different, is there any alternatives to pm3d?
So, here I am trying to plot heatmaps in gnuplot. I have a matrix-formatted text file (with row and column headers), and the command I am using to plot it is
plot "file.txt" matrix rowheaders columnheaders using 1:2:3 w image notitle
The output is this graph:
Obviously, the X and Y labels are useless like this. I believe the problem here is that gnuplot is extracting all labels from the file and plotting them. How would I go about reducing the amount of clutter in here, e.g. plotting every 10th label or so?
Thanks in advance.
Or just make the picture resolution bigger... for instance like 1920,1080 or bigger... like this:
set term pngcairo size 1920,1080
or make the tics numbers like 1000000 smaller and make a label to show that the numbers written on the tics are 1000000 bigger... or both:)
Sorry for my english...
Since stats on datafile containing two columns in gnuplot 4.6 provides mean and sd, I was wondering if I can plot errorbars on the fly instead of creating a third column? Thanks!
Assuming a file data.dat with two columns, you could get those error bars with a command like:
stats 'data.dat' nooutput
plot 'data.dat' using 1:2:(STATS_stddev_y) with errorbars
What would this mean, however? All the points have the same standard deviation, which is the value for the whole data set.
I could provide a more complete answer if you describe your data format/data sets in more detail.
How do you make an horizontal box-and-whiskers plot in gnuplot? Similarly to this one:
Gnuplot can easily be used to produce vertical box-and-whiskers plots with the 'candlesticks' and 'whiskerbars' keywords, but I have not managed to find any example of an horizontal candlesticks/box-and-whiskers horizontal plot produced via gnuplot online.
Example of a vertical plot produced by gnuplot:

Gnuplot generally doesn't switch directions well... for example you can't plot rows instead of columns, and it's hard to make histograms (or any other kind of plot) go horizontal instead of vertical.
People have made horizontal histograms, however, and you might be able to modify the code found at this site.
