Re: [Gnuplot-info] Everything but the function is not appearing

[Thomas S. <t.s...@fz...>]

did you realize the
 line 30: warning: Skipping unreadable file "vels1and12.txt "
messages when plotting?

remove the trailing blank from the filename and everything should work.

and, change the range and tics set commands:

set yrange [0:30]
set xrange [-1.00:1.00]
set xtics 0.40
set mxtics 5
set ytics 5
set mytics 5

[Gnuplot-info] date format on x axis

[fretagi <fr...@mc...>]

Hi All!

I have an issue with x axis, in which from a data file should show every
singla day from 3 of dec 2010 to 31 of the same month as below:
set xdata time
set timefmt "%m/%d/%Y"
set x range ["12/03/2010 09:00:00":"12/31/2010 19:00:00"]
set format x "%m/%d"
set timefmt "%m/%d/%Y %H:%M"

But my png file (graph) only shows 3 dates, so the plot is compacted.

How do I make to show evry single date?

regards

F.R.

[Gnuplot-info] Spacing between candlesticks

[Ker N. <ker...@gm...>]

Hi,
I use gnuplot to draw candlestick chart images. When they are being plot,
the space between each candlestick is either 2 or 3 pixels. How can I change
that so the pixel width between candlesticks is always the same?

I need it that way because I am writing a web page that will recognize on
which candlestick the user made a click. So if the image is , say 500 pixels
and the user clicked at the image with coordinate X=100 , provided that the
width of the candlestick is 5 pixels (which is always the same from what I
have been testing), that was a click at the candle number 20 (100/5=20)

Will appreciate any ideas on how to do this.
Regards
Ker

I tried a high-res bitmap output thinking more pixels might help.  It was
essentially the same.  Postscript didn't help either.

Hmm, can't say I agree with that assertion.  My thinking is that if the
whitespace gets too small, it should disappear, not take over.  In other
words, data should win, not whitespace.  These plots are currently done in
Matlab, and they look very good (some parts do become solid color -- and
that's okay).

That's at least partly caused by 300x300 being way too high a resolution 
for this plot.  That plots consists of just about nothing but sub-pixel 
fragments of lines, the tiniest of which apparently the drawing engine 
refuses to actually output.

For a wireframe drawing to make sense, both technically and visually, 
there has to be at least a bit of white space between the lines.  At 
300x300 isosamples for that function, there just about isn't any.

[Gnuplot-info] perpendicular and parallel signs

Hi all,
I'm looking for a way to print in the postscript terminal, the signs for
perpendicular and parallel.
The first looks like this:

and the second like this:

I'm using the Helvetica font but will change it if necessary.

Thanks a million!

[Gnuplot-info] Windows version of 442...

Hi -

Don't know where else to send this, I don't have a 'news' account.

With the new 442 version for MS Windows (32 bit), any plot comes up with 
weird hyroglyphics for the axes labeling numbers. Also, the legend has 
weird characters.

I'm using Win XP pro; can you advise?

[Gnuplot-info] hidden3d rendering -- hiding too much?

[macro <tw...@gm...>]

Hi folks,

First, many, many thanks to the creators of the excellent gnuplot.  I'm new
to gnuplot but quickly realizing it's a great tool.

I have a matrix that I want to 'splot' 'with lines palette'.  It works just
beautifully if I limit the x & y range.  However, when I splot the entire
matrix (300 x 300 ish), hidden3d causes some of the mesh to disappear.  Here
is a simple script that does the same:

  reset
  set hidden3d
  set isosamples 300
  splot sin(sqrt(x*x+y*y))/sqrt(x*x+y*y) with lines palette

I'm running:
        G N U P L O T
        Version 4.4 patchlevel 2 (Gentoo revision r0)
        last modified Wed Nov 10 22:40:48 EST 2010
        System: Linux 2.6.36-gentoo-r5

Any tips appreciated.  Is it possible to use "pm3d at s depthorder" but with
white fill?  (This is analogous to an approach I've used in the past.)

Thanks!

[Gnuplot-info] Making my default font choice stick

[Christian S. <csc...@uo...>]

Hello,

I'm using Gnuplot 4.4.2 in XP. On some of my machines, I start the windows terminal and get this illegible font. I can change the size and font to something workable without a problem using the options menu that appears when I click the little icon on the top left corner of the gnuplot window, but then when I quit and restart gnuplot, the same horrible font that I had previously comes back.

How can I make my font choice stick?

Thanks!

'help timecolumn' says:

"To find the right `timefmt` string to use, `timecolumn` searches for a
`using` specification with the same column number as its argument.
If one is found, `timefmt` pattern of the target axis for this specifier
is used.  Otherwise, `timecolumn` chooses the x axis `timefmt` per default."

this means, one column for the y axis.

column2 and column3 are the same format, so why can't it use that format

Re: [Gnuplot-info] Need help: Time/date format

[Thomas S. <t.s...@fz...>]

plot 'datafile.dat' using 1:($3-$2)

doesn't work with time data.

use
... using 'timecolumn(3)-timecolumn(2)'
instead, BUT since you are using different time formats for
x and y this will not work, too.
'timecolumn()' can only use the time format of one column, which is
assigned to one coordinate, but you are dealing with two columns.

you could use something like in my previous reply, a little bit extended:

unset ydata
plot "ts.dat" using 1:( \
   s=stringcolumn(2),n=strstrt(s,":"), \
   t=stringcolumn(3),m=strstrt(t,":"), \
   t[1:m-1]+t[m+1:]/60.-s[1:n-1]-s[n+1:]/60.) w lp

[Gnuplot-info] how to write & as a label

[sezgin s. <1se...@gm...>]

Dear all,
I am searching to write & in the label as

set label " 788 & 1690" at 1170,100

but I could not manage since 2 hours.
Is there any person who can help me?

Re: [Gnuplot-info] Need help: Time/date format

[Steffen <st...@on...>]

Wonderful! That works and is even smarter.
But I stumble over the next problem connected with time data:
If a have a file with date, sunrise and sunset time in three columns 
like this:
2010-12-02 7:53 15:55
2010-12-03 7:55 15:54
2010-12-06 7:59 15:53
2010-12-07 8:00 15:53
2010-12-09 8:02 15:52
2010-12-10 8:04 15:52
and I want to plot the length of the day, i.e. sunset-sunrise then
plot 'datafile.dat' using 1:($3-$2)
does not produce the desired result. It seems that every calculation on 
time formatted columns does not produce the expected results. How should 
calculations with dates/times be done?

Pretty much since forever.  The documentation just never picked up on 
the axis argument to 'set timefmt'.  You get a hint that something might 
be afoot if you inspect the timefmt:

gnuplot> set xdata time
gnuplot> show timefmt

         read format for time on x axis is "%d/%m/%y,%H:%M"
         read format for time on t axis is "%d/%m/%y,%H:%M"
         read format for time on u axis is "%d/%m/%y,%H:%M"

gnuplot> set ydata time
gnuplot> show timefmt

         read format for time on y axis is "%d/%m/%y,%H:%M"
         read format for time on x axis is "%d/%m/%y,%H:%M"
         read format for time on t axis is "%d/%m/%y,%H:%M"
         read format for time on u axis is "%d/%m/%y,%H:%M"
         read format for time on v axis is "%d/%m/%y,%H:%M"

There would be no point showing so many timefmt strings if not at least 
some of them were independent...

Re: [Gnuplot-info] stacked histograms with date X axis

[<da...@la...>]

I never got an answer back on this.

one thought I had, but havn't had a chance to try is if it could be done 
with repeated newhistorgram calls, giving the time as the X location.

is there some easier way to do this?

as of what release? the 4.4 documentation says that the both axis can be 
time (which I had missed), but it says that they must use the same 
timefmt.

No.  This works:

gnuplot> set xdata time
gnuplot> set ydata time
gnuplot> set timefmt x '%Y-%m-%d'
gnuplot> set timefmt y '%H:%M'
gnuplot> p '-' u 1:2 w lp
