[Gnuplot-info] Load strings

[GnuFrank <the...@ya...>]

I would like to load strings from a file, put them in a variable and them
print them on-screen with "set label" command.

Does anyone know how I could load strings and keep them in memory ?

Thanks

[Gnuplot-info] Add comment to a graph

[GnuFrank <the...@ya...>]

Hi,


I would like to add comments to a graph. Like a custom "key".

Like a new box with text placed where I want it to be.

Does anyone know how I could do this ?

Thanks

Gentlemen,

It would be a very good thing, when in parametric mode, if the parameter =

Please give this your consideration.

Did you check that these options were actually accepted by your version 
of gnuplot?

Your build logfile probably can.  The printout of "show version long" 
also should.  The most likely explanation is that you didn't have GD 
installed where ./configure would have found it.

By putting the day into the data file, and telling gnuplot where to find it.

That would only happen if you used option 'smooth uniq' or something. 
gnuplot doesn't summarize y values unless explicitly asked to.

Either by setting up a long-form 'set xtics' statement (works with every 
version you're likely to have), or using the 'with labels' plot style 
new with version 4.2

The postscript driver doesn't support that, and for good reason, too --- 
it's not nice to whoever's paying the toner in your printer to fill 
printouts with solid black.  If you really need the plots inverted, you 
can always do it outside gnuplot.  Ghostscript or pstoedit spring to 
minds as tools for this job.

That's because gnuplot.ini has nothing to do with it.  Colours are 
controlled by wgnuplot.ini for the windows terminal, or directly via 
linecolor options.

As far as I know the postscript terminal does not provide 
this feature directly. I would solve this problem by 
producing a regular postscript output with the terminal 
option monochrome (black lines on a white surface), which I 
then would open in my favourite picture editor (e.g. The 
Gimp, http://www.gimp.org ) to revert the colors, so that 
black becomes white and vice versa. Some hints can also be 
found in gnuplots help, see "help editing postscript".


> 2. In windows I do
> not succees to control the colors thru gnuplot.ini
I suppose, your problem is, that gnuplot under Windows uses 
wgnuplot.ini for the settings of the colors and other 
things (notice the w in front). See "help wgnuplot.ini" for 
more detailled information.

Lars

Dear Gnuplot
First let me thank you for the Gnuplot code which has been very helpful during my work. I have two quesyions:
1. When I use 'postscript' terminal, how can I get a black background with white lines? I can do it on the screen but unable to get a postscripy.
2. In windows I do not succees to control the colors thru gnuplot.ini

Sure it does, since it was designed to plot x/y-datafiles 
and your datafile only contains x-values from 1 to 24. But 
there ist hope: You may read more about gnuplots facilities 
to deal with timeseries. Please see "help format" and "help  
timefmt". 
If your datafile is filled completely with values given for 
_every_ hour, one other way of plotting it would be to use 
the line number of the datafile as x-value. I would solve 
your problem by something like this:
  plot "file" using ($0*24):2
$0 stands for the line number. By this you can use it like 
every other variable within mathematical expressions, that 
may be used as one of the arguments of the using-option.

For this there are special values "0", "-1" and "-2" within 
the using-option, see "help using". 

If you want to use the special names of the lines given as 
column one for the names of the xtics, you may use the 
various features given by the scanf-library in combination 
with "set xtics". Some of the facilities of scanf are also 
described in the help-text of using.

[Gnuplot-info] Steps on X axis

[Ilya E. <ily...@gm...>]

    Hi, folks!
There is gnuplot 4.0 patchlevel 0 under FreeBSD 5.5, installed from ports
with default options.
Data file contains records like following:
09 13.62
10 27.55
..where first column is a hour.
Total count of records is more than 24 (data for many days).

How to display data without summarizing records with the same hour value?
Currently, "plot 'datafile' using 1:2" displays 24 steps only,
each summarizes Y-values from records for Nth hour.

More widely, how to use non-numeric values for X axis (or implicitly
interpret them as non-numeric)
and display Y values with fixed step?
For example,
WakeUp 1.234   # display at X=1
GotoHome 5.678 # display at X=2
...

Sir,

I send one mail regarding non working of -rv option in gnuplot. but i

i found the problem some how. but i dont know how to correct it.  
Previously to enable the screen savers, in my .profile i added  
/usr/X11R6/bin to PATH variable.
after that gnuplot is not taking -rv option.

Please do the necessary action.

You'll have to use pre-fixed ranges then.  gnuplot doesn't do 
interdependency between axes.  The new (in upcoming 4.2) feature of 
exporting the range end values to variables may help here, if you're OK 
with doing a "dummy" plot first, to find the numbers and copy them to 
the other axes.

See 'help ticslevel'.  That's all gnuplot can do for you about this. 
Note that zero-axes are already a problem in 2D plots, which gets 
considerably worse in 3D.  They end up in a region where data should be, 
tending to make the scale, the data, or even both of them unreadable.
