[Gnuplot-info] Rotation about third axis for ‘splot’s?

[Elias A. <eli...@gm...>]

Hi,

With ’set view’ (or by dragging with the mouse), I can set two angles of 
rotation for the viewpoint in a ‘splot’: ‘rot_x’ and ‘rot_z’.  Is there 
also a way to set a “rot_y”?

By way of example, consider the following plot of a spiral around the z 
axis (my actual plot is similar, but a bit more complicated.):

set map cyl
set zzeroax ls -1
splot [-5:5] [-5:5] '+' u ($1*pi):1:(1) w l

Now, I would like to have the z axis point “diagonally into the screen”, 
so that it looks like the spiral is going “off into the distance“, if 
you will.  (Note: I am not asking about perspective projection; that 
might be nice for my plot, but is not required.)

Current gnuplot (version 4.6) allows you to attach a "pointinterval"
property, "pi" for short.
See for example the second plot in

[Gnuplot-info] Frequency of Points with Linespoints Option

[Matthew C. <mp...@gm...>]

Hi,

First, I saw a related post about my question from the late 90's, and
couldn't find anything else...so I figured I'd email the mailing list.
The problem is pretty simple: I have line plots with 10000's of data
points, so differentiating between multiple data sets on a single plot
is very difficult with setting the linetype (they all pretty much look
like solid lines). Instead, I'd like to use linespoints with symbols
popping up at a reasonable frequency. Anybody know how to do this?
Thanks for the help.

Thanks,
Matthew

You'll want to do a "3D fit" of a function that describes your equation, 
i.e., something like this:

	implicit(V,I) = I0*exp((U-I*Rs)/n/k/T - 1.0) - I
	T=297.0
	fit implicit(x,y) 'data' using 1:2:(0.0):(1.0) via I0,Rs,n,T

The drawback is that the z errors are totally bogus, and have no 
relation at all to your data's precision.  So don't put too much trust 
into the result, and none whatsoever into the parameter errors you get.

[Gnuplot-info] fitting a implicit function with gnuplot

[U M. <uli...@gm...>]

Hi,

I have the following problem for a school project.
We collected data from a diode with an resistor in series.
Now I am trying to fit this data in order to get the value of the series
resistance.
The following formula I used:
I = I0*exp((x-I*Rs)/nkT-1)  (x=V) via I0, Rs, n, T=297
I know the problem could be solved by change to V = ... but I like to keep
V on the x-axies.
Kind regards

Re: [Gnuplot-info] font handling in emf terminal

[Tom L. <tl...@cp...>]

I feel your pain..!! I can't bear to move to a bitmap format, so...

I try to espouse EPS, from the epslatex terminal.

But it requires a LaTeX install- no probs for you, since you're in Linux... And miktex is easy enough on a PC...

And then there's the problem of embedding a preview so it's not a red X in Word; either a low res one, that looks terrible, or a high res one, that makes the EPS as big as a bitmap...

And then the recipient may not send to a PS printer or virtual printer, and the horrible preview gets printed.. :-(

Every time I go around this loop, it becomes clear the problem is.... Word...!!

I wish MS and Adobe could settle whatever spat it is that means you can't just drop a PDF into Word like I do in <any other program you can name> on my Mac...

Or, I wish I could make Word vanish, to be replaced by LaTeX....

[Gnuplot-info] font handling in emf terminal

[kintantee <jes...@un...>]

Hello -

I am using the EMF terminal to create plots for insertion into Microsoft
Word documents (a necessary evil, do you have better idea?).

How are the fonts handled for this terminal? Are there environment variables
that need to be set? I have been able to apply a few basic fonts (Times,
Symbol, Arial [default?]) by trial and error.

I am using Gnuplot 4.6.3 in Linux.

Thanks!

Both awk and strcol have to actually parse the line,
so I suspect if speed is the issue then 
   plot '< grep M file'
is faster than either of them.

Do you have any suggestions?

The problem is that each output medium (svg/html/wxt/qt/x11) provides
very different basic operations and mechanisms for triggering them.
Gnuplot tries to create more or less the same result on all of them, but
the similarity is limited by the different tools that are available.

That said, the intent is that the active area for toggling the plot consists
of (1) the symbol itself, which in your case is very small, and
(2) the rectangular bounding box for the text associated with that symbol.
So it should work to click on the plot label text.

It is certainly possible.  Different browsers use different svg
interpreters,
so you might get better response with a different browser.

[Gnuplot-info] scatterplot legend mousing: sample points too small

[Alan E. D. <ln...@gm...>]

I am plotting 12 sets of data, with mousing enabled, in distinct colors.
In order to turn off the plot for one of the datasets, one clicks on the
legend line for that dataset's color.   This is a large dataset,
relatively, with thousands of points for each set, plotted in an extremely
small size of 0.04 or 0.05.

I have not found a way to independenly specify the legend to display a
sample of the color in any other manner than as a colored point.   I have
seen some kludges mentioned, such as to plot an empty set first, then plot
over it with the data.  The issue here is that I am plotting 12 different
files at one time.

Is there some way to use a square or rectangle of color as the sample, of
arbitrary size?

Another problem: for different terminals, the legend should be clicked at
some different part of the line in the legend.  For the svg terminal, this
seems to not be the sample, while in the wxt terminal, it is the sample (of
course, it is spotty, because the samples are also of the small size
0.05mm.

I also notice that with the svg terminal, when viewed with a browser, the
response is slow.  Is it possible this is due to the large size (5MB) of
the file?

This is a very interesting capability.   Can anyone shed light on how to
get this working properly?

Re: [Gnuplot-info] margin and ratio -2. for instance

[cédric o. <ced...@gm...>]

I think I am wrong,

it is likely that setting the size for one dimension (say Y) implies,
by the given ratio and a given x range, a size for X. So margins are
to be well set in accordance.

[Gnuplot-info] margin and ratio -2. for instance

[cédric o. <ced...@gm...>]

Hi,

I am going on plotting with gnuplot.

I face a difficulty in setting with accuracy the positions of plots in
a multiplot session.

When I do not use set size ratio -5. for instance, no problem my plots
are very well located, one close to each other. To do that, I used set
{l,r,t,b}margin as explained in the demos.

However, I need to use the ratio option in order to plot vectors of a
given field but on axis with different units. For instance, I plot the
components of the speed u(z,t) v(z,t) as a function of time and
vertical position z. The scale for the vector representation needs to
be the same for the two components so I set the ratio (-5 for
instance) and then multiply the u component by 5.

Margins are not respected anymore. In fact, they are for the upper and
lower plots. But for the left and right plots, they are not.

I have read "set size" was ignored when setting margins at screen
although the ratio seems to be respected.

Any hint?

Thank you by advance,

Cédric

[Gnuplot-info] landscript does not work

[Jian-Ming Z. <jm...@gm...>]

Hi,

I set landscript to the plot orientation of the postscript terminal,
but it seems not working correctly.

gnuplot> set terminal postscript landscape enhanced
Terminal type set to 'postscript'
Options are 'landscape enhanced defaultplex \
   leveldefault monochrome colortext \
   dashed dashlength 1.0 linewidth 1.0 butt noclip \
   nobackground \
   palfuncparam 2000,0.003 \
   "Helvetica" 14  fontscale 1.0 '

gnuplot> set output 'terminal.eps'
gnuplot> test terminal

I use evince to see the file terminal.eps, but the orientation is
portrait, not landscape.

I checked terminal.eps and saw "%%Orientation: Landscape" in the file.
Is anything wrong?

Thanks.

[Gnuplot-info] multiplot and animation - large data file on one subplot

[cédric o. <ced...@gm...>]

Dear all,

I am trying to make animations with multiplot.

On the first plot, I would like to plot the whole time serie u(x,t)
while on the second one, I'd like to plot the profile u(x,t0). I would
like to make an animation of that by updating the profile at each
iteration of a loop.

I have been able to do that with multiplot but since the time serie is
large (in fact, I plot vectors), I would like gnuplot not to replot
the first plot for each iteration. On this plot, I would like only to
plot a line indicating at which time t0 we are.

Thank you by advance,

Cédric
