I am trying to get a dataset plotted using histograms with errorbars. My d= ata=20 is in pairs and (currently) is in the form of two columns, the first a=20 experimental value and the second the stdev thus: 1.065 0.04 1.102 0.04 1.02 0.08 1.15 0.06 and so forth. My desire is for each PAIR of rows be plotted side-by-side with touching=20 histogram boxes, a space, then the next pair plotted, etc. I have tried changing the format of the file so all the first values of eac= h=20 pair are in one column and the second in a column beneath the first with a= =20 space. Nothing is working so far. I am using the index <n> command to=20 select the pair or dataset as appropriate and I've tried playing with gap=20 size. In no case have I managed to get pairs of side-by-side histograms. How do I do this? =2D-=20 Reichstag fire is to Hitler as 9/11 is to Bush |

Hi Lorenzo, I don't have an answer to your question - your essentially plotting your data as a rectangular plot, with R and theta on the x and y axis. This is fine and a perfectly valid way of representing your data, but it seems to me that what you want is to plot your data on a cylinder. So the final image would be a coloured cylinder. While I haven't worked in cylindrical coordinates before, I know it is possible with gnuplot.... try looking at http://gnuplot.sourceforge.net/demo/world.html for some ideas.... I personally wouldn't use gnuplot to plot this data, but matlab using patches or even povray which is freely available and produces some beautiful results. Both of which will require writing a program to convert your data into essentially coloured tiles. But somebody on here might be able to do it much simpler in gnuplot - I'd be interested to see the solution! Gavin. Hello, And thanks for your suggestion. It seems there is a problem, though. Somehow gnuplot does not understand that it is working on a cylinder cross section. If I try: set dgrid3d 10,10 set hidden3d set pm3d splot "example.txt" u 1:2:3 with lines where "example.txt" is the file containing the data as shown in the email, what I get is a rectangular grid. Is it simply an artifact due to the low number of grid points or am I doing something wrong? Many thanks Lorenzo ____________________________________________________________________________________ Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. http://mobile.yahoo.com/mobileweb/onesearch?refer=1ONXIC |

That's going to be a little tricky. In particular, the seam where theta jumps by 2*pi will be apparent in the plot. > Furthermore, I do not have necessarily an equally spaced grid. It doesn't have to equally spaced as long as it's topologically rectangular, i.e. consists of N rows of M entries. You have to inform gnuplot about where one row ends and the next one begins. See 'help glossary' and 'help datafile' and watch out for 'grid structure'. |

But it isn't. Either fix the program running gnuplot, or put gnuplot on the PATH. |

Hello, And thanks for your suggestion. It seems there is a problem, though. Somehow gnuplot does not understand that it is working on a cylinder cross section. If I try: set dgrid3d 10,10 set hidden3d set pm3d splot "example.txt" u 1:2:3 with lines where "example.txt" is the file containing the data as shown in the email, what I get is a rectangular grid. Is it simply an artifact due to the low number of grid points or am I doing something wrong?

a contour plot is not so easy unless you have your data on a grid. re-binning a few data points into a grid with 'dgrid3d' doesn't work. so, either you have a reasonable number of data points - so many, that 'set dgrid3d' works - or you do the re-binning (= filling a 2d-histogram) outside of gnuplot. or, for a very low number of data points, a 'poor man's' solution could be: set xrange [-1:1] set yrange [-1:1] set view map set mapping cyl splot 'datafile' using 1:3:2 with points pointtype 5 pointsize 3 palette Lorenzo Isella wrote: > > Dear All, > I am fairly new to data plotting and visualization. > My problem should be simple, but it is not straightforward to tackle in > R or Python. > On the cross section of a pipe (i.e. on a circle) I have a temperature > reading of the kind: T=T(r,theta). > I would like to make a 2D contour plot using colors such that one can see > that the domain where I am plotting is actually a circle. > Furthermore, I do not have necessarily an equally spaced grid. > For instance, let me consider the case of 5 theta's and 7 radial > position and consequently 35 values of T (just a simple test): > > theta > R T > 0.000000000000000000e+00 0.000000000000000000e+00 5.459815003314423620e+01 > 0.000000000000000000e+00 1.666666666666666574e-01 4.853828855239110851e+01 > 0.000000000000000000e+00 3.333333333333333148e-01 4.315101251901344881e+01 > 0.000000000000000000e+00 5.000000000000000000e-01 3.836167151642037965e+01 > 0.000000000000000000e+00 6.666666666666666297e-01 3.410390059527122020e+01 > 0.000000000000000000e+00 8.333333333333332593e-01 3.031870066752165016e+01 > 0.000000000000000000e+00 1.000000000000000000e+00 2.695362096775039973e+01 > 1.570796326794896558e+00 0.000000000000000000e+00 2.396203225329512776e+01 > 1.570796326794896558e+00 1.666666666666666574e-01 2.130248067207563523e+01 > 1.570796326794896558e+00 3.333333333333333148e-01 1.893811334477913277e+01 > 1.570796326794896558e+00 5.000000000000000000e-01 1.683616770181326316e+01 > 1.570796326794896558e+00 6.666666666666666297e-01 1.496751749887080329e+01 > 1.570796326794896558e+00 8.333333333333332593e-01 1.330626922033307302e+01 > 1.570796326794896558e+00 1.000000000000000000e+00 1.182940327795447999e+01 > 3.141592653589793116e+00 0.000000000000000000e+00 1.051645503298913731e+01 > 3.141592653589793116e+00 1.666666666666666574e-01 9.349231221746512333e+00 > 3.141592653589793116e+00 3.333333333333333148e-01 8.311557855141172624e+00 > 3.141592653589793116e+00 5.000000000000000000e-01 7.389056098930650407e+00 > 3.141592653589793116e+00 6.666666666666666297e-01 6.568943029058285532e+00 > 3.141592653589793116e+00 8.333333333333332593e-01 5.839854501207304871e+00 > 3.141592653589793116e+00 1.000000000000000000e+00 5.191687680104649871e+00 > 4.712388980384689674e+00 0.000000000000000000e+00 4.615461046534314882e+00 > 4.712388980384689674e+00 1.666666666666666574e-01 4.103189942205120566e+00 > 4.712388980384689674e+00 3.333333333333333148e-01 3.647775927922803252e+00 > 4.712388980384689674e+00 5.000000000000000000e-01 3.242908421924544982e+00 > 4.712388980384689674e+00 6.666666666666666297e-01 2.882977255397825012e+00 > 4.712388980384689674e+00 8.333333333333332593e-01 2.562994933482758420e+00 > 4.712388980384689674e+00 1.000000000000000000e+00 2.278527524544009530e+00 > 6.283185307179586232e+00 0.000000000000000000e+00 2.025633220058637107e+00 > 6.283185307179586232e+00 1.666666666666666574e-01 1.800807713756398032e+00 > 6.283185307179586232e+00 3.333333333333333148e-01 1.600935643142084031e+00 > 6.283185307179586232e+00 5.000000000000000000e-01 1.423247420534685892e+00 > 6.283185307179586232e+00 6.666666666666666297e-01 1.265280855439646635e+00 > 6.283185307179586232e+00 8.333333333333332593e-01 1.124847036463023642e+00 > 6.283185307179586232e+00 1.000000000000000000e+00 1.000000000000000000e+00 > > > > How would you plot them in order to have a 2D-color plot where one can > understand we are working on a circle (well, maybe it will look like > something different since I have only a few grid points, but the aim > is clear, I hope)? > Despite its simplicity, this has been taking me a long time and I am not > done yet.

Dear All,
I am fairly new to data plotting and visualization.
My problem should be simple, but it is not straightforward to tackle in
R or Python.
On the cross section of a pipe (i.e. on a circle) I have a temperature
reading of the kind: T=T(r,theta).
I would like to make a 2D contour plot using colors such that one can see
that the domain where I am plotting is actually a circle.
Furthermore, I do not have necessarily an equally spaced grid.
For instance, let me consider the case of 5 theta's and 7 radial
position and consequently 35 values of T (just a simple test):
theta
R T

How would you plot them in order to have a 2D-color plot where one can
understand we are working on a circle (well, maybe it will look like
something different since I have only a few grid points, but the aim
is clear, I hope)?
Despite its simplicity, this has been taking me a long time and I am not
done yet. Someone has recently suggested to learn VTK, but it may be too
much for what I have in mind.
Anyone who can give me a simple script to read that data and get a
contour plot on a pipe's cross section would help me a lot (I am sure
it must amount to a few lines).
Kind Regards
Lorenzo

Dear,
I have a problem with ranges.
Attached is my example.
The blue curve (error) is an oscillation function between the error lines
at 1.67 and -1.67.
samples=101.eps:
obtained with set samples 101
As you can see the oscillating function practically
never reaches the limits. This is not because the function is wrong,
but because the sampling is insufficient. Therefore we increase the number
of sampling points.
samples=1001.eps:
obtained with set samples 1001
Much better, but still not sufficient.
Some of the extrema are not reached.
The problem is that the sampling x doesn't necessary coincides
with the x value of an extremum.
Therefore, I propose the following extension of the range of the
plot command:
plot [0:x1:x2:x3:x4:x5:x6:3.5] ln_ITcan_log(x) axes x1y1 notitle with
lines linetype 1 linewidth 5, \
log_error_log(x) axes x1y2
notitle with lines linetype 3 linewidth 5
between each consecutive x values for the range a number of samples defined
by set samples would be taken. That way one would obtain:
1) a polyline wich is continuous.
2) a polyline wich reaches the extrema. Indeed, the x values of the
extrema would be sampled.
What about the idea?
Best regards,
Francky Leyn

Hello gnuplot team, I recently installed gnuplot 4.2 on my mac osX 10.4.9. Running gnuplot from the terminal, I find it a pain to type in the directory path every time I start the program and need to 'cd' to a different location. Is there a way that I can bring up a graphical dialog box that will allow me to select the directory using the mouse by typing the 'cd' command? Thank you. -Suchit Patel -- Suchit Patel Weill Cornell/Rockefeller/Sloan Kettering Tri-Institutional MD/PhD Program 420 East 70 Street, Apt 3D New York, NY 10021 646.696.6105 |

Dear, attached a gnuplot deck. For some reason, the x2 axis is drawn incorrectly. I don't find a reason for this. Is this perhaps a bug? Hoping you will find it's not a bug. Regards, Francky Leyn |
