Well, this whole mess comes from the fact that gnuplot, it seems, can not read 
A COLUMN in an arbitrary formatted way. 

There is a substitute for time, i.e. 'timefmt' where this thing with a sign is 
probably a bug and has to be fixed in such a way that it is taken into account 
when it sits only before the %tH. Otherwise, it has no meaning.

But it would be cool to make a formatted reading available:

set xdata format "%tH:%tM:%tS"
set ydata format "%tH:%tM:%tS"
plot 'datafile' using ($1.1+$1.2/60+$1.3/3600):($2.1+$2.2/60+$2.3/3600)

where dotted notation indicates a positional value according to a format 
string.

Thanks,
Sergei

A little bit of both, I'd say: %tH does work, but not for a value of 
minus _zero_ hours.

 From a user point-of-view that's a bug, but I see how it might be 
tricky to get the implementation to do what this wants to achieve, given 
that plus zero and minus zero are somewhat hard to distinguish.

So the sign of the hours field extends over to the minutes and seconds.

I'll assume (although the documentation doesn't say so) that this was 
meant to work like that.

Hmm, so there's no way to flip the minutes back to positive once the 
hours are negative.  That IMHO casts doubt on the whole idea of 
inheriting the sign from one field to the other (not to mention what 
might happen if some devious mind decided to use these fields in reverse 
order, i.e. "%tS:%tM:%tH").

> gnuplot> print strptime(myTimeFmt,"01:-02:03.4")  
> 3483.4

But if you start with positive hours, the minutes alone can be negative, 
while the seconds still default to positive.  The seconds can be 
negative all by themselves, though:

[Gnuplot-info] strptime() fails to recognize negative hours

[Sergei N. <vo...@ra...>]

Hi!
posting a question on https://stackoverflow.com/questions/60985800/reading-formatted-column-in-gnuplot it came out that strptime() does not recognize 
negative sign in cases like the following:

gnuplot> myTimeFmt = "%tH:%tM:%tS"
gnuplot> print strptime(myTimeFmt,"-00:24:25.3")
1465.3
gnuplot> print strptime(myTimeFmt,"00:-24:25.3")
-1465.3
gnuplot> 

Is there a bug or it should work like this? If it does, how one would take 
this minus into account?

Thanks,
Sergei

[Gnuplot-info] Fitting a curve to time data

[Reginald B. <pul...@ya...>]

I'm trying to do a fit and plot the line with a time axis.  I can do the fit with an ordinal axis (i.e. 0:2), but can't figure out how to make a fit with time or display the ordinal fit in time.

plt2.pdf shows what I'm trying to fit so I can show the date the line meets 0%.

plt2a.pdf shows the result for:

g(x) = a + b*x
fit g(x) 'b' u 0:2 via a,b
set term post lw 3
set out 'plt2a.ps'
plot 'b' u 0:2,g(x)

I just want to do the same thing but with the time axis as shown in plt2.pdf.  I've read the help and demos, but just don't quite get it.  I'm running 5.0 patch level 6 on OpenIndiana.  If this is better done with a more recent version I'll build that from source and install it.

Thanks,
Reg

[Gnuplot-info] Starting the element count (x-axis) at 0 even when plotting data not at the start of file

[Dario S. <san...@gm...>]

Hello, list.

I have a large .csv file and I need to plot only 500 of its elements which
are towards the end.

I would still like to have the x-axis to count the elements starting from 0.

I have the following script which generates this error: "all points y value
undefined!". It must be a problem with the operation that I perform on $0
because I can plot if I remove the subtraction.

Would you please help me understand what I'm doing wrong and, generally,
what is the best practice to start counting the elements from zero even
when the elements do not start from the zero-position?

Thanks,
Dario

Re: [Gnuplot-info] Clogged tics in high-res pngcairo terminal

[Ethan M. <eam...@gm...>]

That output looks similar to previous reports that traced back to a bad
version of the pango/cairo libraries on the affected machines.  In other
words, to fix it you need to replace those libraries. No need to change
anything in gnuplot per se.  Previous reporters said that "downgrading" the
libraries fixed it for them but I do not remember the specific versions
involved.  Or if you are working in a LaTeX friendly environment, I suggest
using the tikz terminal to generate pdf output for use with pdflatex.

[Gnuplot-info] Clogged tics in high-res pngcairo terminal

[Dario S. <san...@gm...>]

Hello, dear list.

I am plotting a two-column, 1000-element-each CSV file using the script
attached.

I am using pngcairo with enhanced font times 40 and a resolution of
4096x2160.

The resulting .png has the correct plots but the numbers of the values of
the tics are overlapped. See this image:
https://www.dropbox.com/s/w1a9ch0emh3l1zl/singleplot.png?dl=0.

If using the eps terminal, there is no problem with the tics, although I
don't seem to be able to use 'times', and I happened to have a hard time
loading eps files in the latex template of my uni so I'd prefer to stick to
.png files.

I have generated several .png files in the past using the same pngcairo
terminal as in the script and it was fine.

If I had accidentally set something wrong, shouldn't the 'reset' at the end
get rid of that?

Thank you so much for your help.

Dario

    set palette defined (0 "white", 1 "dark-blue")
    set cbrange [2:N]
    plot for [i=2:N] "input.dat" using 1:i with lines lc palette i

[oops] that should be

    plot for [i=2:N] "input.dat" using 1:i with lines lc palette cb i

The keyword "cb" means to map the palette through the colorbox range.

    plot for [i=2:N] "input.dat" using 1:i with lines lc palette i

[Gnuplot-info] Coloring multi-column plot by column number

[t.sefzick <t.s...@gm...>]

Hi,

you could specify the linecolor as ARGBvalue by adding the "linecolor"
option to your plot command:

plot for [i=2:N] "input.dat" u 1:i with lines title "" linewidth 2 \
  linecolor rgb ((255-i) << 16) + ((255-i) << 8) + 255

starting from (nearly) white and ending with dark blue.
Works, if N is around 250 but below 255, otherwise you have
to add a scaling factor to the color computation.

[Gnuplot-info] Coloring multi-column plot by column number

[Debostuti G. <deb...@gm...>]

Hi

I have a data set (input.dat) which looks as below:

#C1     C2    C3 ...   C250
1          -2.1    -1.9...  -1.1
2
.
.
.
10       -0.9    1.3        1.7

My intention was that points 1 to 10 will be joined in each column to form
each plot, and therefore I'll have a 249-line plot. This I am able to
achieve by the following:

N = system("awk 'NR==1{print NF}' input.dat")
plot for [i=2:N] "input.dat" u 1:i with lines title "" linewidth 2

Using this I obtain a plot where each line is plotted with a different
color. I want the plots to be colored by a defined palette where the range
is the column number itself, i.e., C2 will be the lightest blue and C250
the darkest blue, since the columns are arranged based on a factor.

Appreciate any help in this regard.

Thank you

[Gnuplot-info] Changing the default plot color in multi column plot

[Debostuti G. <deb...@gm...>]

Hi

I have a data set (input.dat) which looks as below:

#C1     C2    C3 ...   C250
1          -2.1    -1.9...  -1.1
2
.
.
.
10       -0.9    1.3        1.7

My intention was that points 1 to 10 will be joined in each column to form
each plot, and therefore I'll have a 249-line plot. This I am able to
achieve by the following:

N = system("awk 'NR==1{print NF}' input.dat")
plot for [i=2:N] "input.dat" u 1:i with lines title "" linewidth 2

However, each line in the plot has a different color. I want the plots to
be colored by a defined palette where the range is the column number
itself. E.g., C2 will be the lightest blue and C250 the darkest blue. I
require this because the columns are arranged based on a factor.


Thanks in advance for any help in this regard.

You can read 'help plot with table' and ponder what that default format

[Gnuplot-info] Truncation

[Patrick D. <pd...@gm...>]

Hello,

When I do
plot "SPANF138-1.asc"
my plot is correct.
When I do
set table $DATA;  plot "SPANF138-1.asc" u 1:2 "%lf %lf" w table; unset table
and
plot $DATA

The plot is wrong because the data of the x-axis are truncated

print $DATA

7174.09 	 0.789246
 7174.1 	 0.782853
 7174.1 	 0.777181
 7174.1 	 0.77275
 7174.1 	 0.769426
 7174.1 	 0.767722
 7174.1 	 0.767362

At least 3 digits are missing.

How can I fix the issue?

Thanks

There are no attachments. If you want help resolving lots of errors, you
should quote at least a representative subset of them in your post.
Anything else just wastes other users' time as they have to spend it asking
you what you're trying to explain.

[Dhara R. <rav...@gm...>]

Hello everyone,

First i had work in the gnuplot old version, and i made scripts for lots of

???

[Gnuplot-info] A new C++ library that uses Gnuplot

[Vincent P. <pic...@gm...>]

Hello all,
That is my first post here.
I just wanted to point out that I just wrote a small C++ library that makes
it easier to create scripts for Gnuplot.
https://github.com/vincent-picaud/GnuPlotScripting
If you find it interesting, feel free to add a link in the "external link"
section. I intend to maintain this library which is simple and easy to use.
Best,
Vincent
