[Gnuplot-info] Default font file

[Martin W. <ma...@gk...>]

I am using gnuplot to generate a png file with default font settings.

On my main PC I get a plot with a nice sans-serif font,
while on a Raspberry Pi I get a different font which has
slightly wider and lighter characters.

How do I find out which font gnuplot is using and what package
I need to install on the Raspberry pi to get it to use
the same font?

Re: [Gnuplot-info] log color bar: out of range data --> invisible

[theozh <th...@gm...>]

Hi John,

it is absolutely clear to me that negative values cannot be displayed in
log scale. If I wanted them to be displayed I would use the absolute
value abs(x). That should work for column data:
plot "ColumnData.dat" u 1:(abs($2))

Actually, I couldn't tell how one could do abs(x) on matrix data???

Nevertheless, I want to *ignore* negative values. And I do not want to
change all datafiles.
Why is gnuplot displaying negative values in log scale as maximum value?

Theo.

That's not a function unless you have both a previously defined function 
y_(), and a previously defined variable y.

[Gnuplot-info] fit function ?

[Sunil M. D. <sm...@gm...>]

Hi,


Sorry about my ignorance about gnu, as I am newbie ...


I am confused about following type of function



f(x) = b/x**nb * exp(y_(y)/k)


f(x,y) = (b/(x**nb))*exp(y/k)


Any help to  understand the difference or similarity is appreciated


Thanks

Re: [Gnuplot-info] log color bar: out of range data --> invisible

[BBands <bb...@gm...>]

As far as i know, negative values are a show stopper when using log
scaling. A fellow by the name of John McGinley devised a hack to plot data
that spanned 0 on opposing log scales by skipping near zero values and
using a mirrored (inverted) scale for negative values, but for normal folks
negative values are not defined for log scales.

[Gnuplot-info] log color bar: out of range data --> invisible

[theozh <th...@gm...>]

Hi there,

In a matrix plot with logarithmic colorbar scale it is clear that
negative numbers cannot be displayed.

set logscale cb
set cbrange[1e-10:1e-4]
set palette rgbformulae 7,5,15
plot "Matrix.dat" matrix with image

Therefore, I would like to display the negative values as "missing
values", i.e. invisible (white or transparent).
However, it seems that gnuplot gives these negative datapoints the color
of the maximum value instead of the minimum value or treating it as
missing data. How can I achieve that?

Thanks for any hints. Theo.

[Gnuplot-info] 3d plots with error

[smdogra <sm...@gm...>]

Dear Experts,
I am learning the gnu plotting.

I have a simple problem.
I have data file  like this 
x y value_at_x_y error_on_value

I would like to have the 3D plot with errors on the points 

Another question 
I fit this data with function of the type f(x,y). 
Now I would like to have plot  of data points with the fit values for each
bin of y  so that my plots look like two dimensional ( in other words, I
would like to have the projections of y on x)  

Any help will be appreciated. 

Thank you 
sunil

Same with 5.0.0.  Am I the only one with this problem, and if so, what 
could be so special about me?

Ok, I tested this again (removing the color column and lc var) and it did the 
right thing.

all three graphs contain the same data elements, therefor the same colors 
(moderate is always the column 4, severe is always column 5 critical is always 
6)

Is there any way to specify what colors are used for the keys?

I'd be happy to let it default on the colors, but fear was that it would end up 
doing each graph as a different set of colors.


Or am I just on the wrong track for the way to generate these graphs?

I'm trying to make a pie graph for each row in the file, using the columnheaders 
for the names of each section.

oops - sorry not "as a palette color" - that should be "as a linetype

Re: [Gnuplot-info] problem with legend in svg pie-chart

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

> anyone have any idea what's going wrong here?

You have told gnuplot to plot with "lc variable",  which means
"interpret the final using spec as a palette color".  That's fine for
the plot itself.

But how are you expecting the program to know what color you want in
the key sample?
You have made three plots, each containing multiple colors.  The key
sample for each plot can only be one color, so where would this come
from?   I don't actually know myself, but in any case I don't see how
it can be expected to come out as some particular color among the
several that appear in the corresponding plot.

I haven't had time to seriously look at this.  There may or may not be
a simple way to do what you want, but at the moment I (like the
program itself) don't exactly know what that is.

No.  Because the point interval is expressed in terms of point _count_, 
not x axis _value_.  I.e. if you want log-spaced points, you'll have to 
prepare a log-spaced data set.

Re: [Gnuplot-info] Logarithmically Spaced Points

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

John,

Thanks for the reply. To be clear, I am not referring to the tics on the 
x-axis, but the points on a linespoints curve in the graph. 
Specifically, I want to be able to set the point interval for the points 
on the line in an exponential fashion, rather than a linear option for 
"point interval". In other words, if I have have 1000 (x,y) points to 
plot, I would like a linespoints curve with point markers at (x1,y1), 
(x10,y10), (x100,y100), (x1000,y1000).Is it possible to do that?

Thanks,
Matthew

[Gnuplot-info] Logarithmically Spaced Points

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

Hi,

I am using the epslatex terminal available in gnuplot for making plots. 
I am plotting data on a linear y axis and logarithmic x axis. I would 
like to plot the data with linespoints so the different curves can 
easily be differentiated from one another. Specifying the point interval 
option, however, does not look very good on a logarithmic x axis, 
because for large x values you essentially get many points overlapping 
each other. Is it possible to use a logarithmically-spaced point 
interval, so that points will become evenly spaced in the x direction on 
a logarithmic x axis? To give an example, instead of point every 10 
units (which will become very crowded for x > 100), can I place the 
points at x=1,10,100,1000,10000?

Thanks,
Matthew

both items are leftovers from prior work.

if I didn't have the wc at the end of this and just output the first element on 
each line, gnuplot would disregard the newline and run them all together into 
one string, adding a space on the end of each line avoids this.

In my case, the data is already sorted by the SQL, so I wouldn't need to sort it 
again (although in the case of creating the pie charts, it's only one line per 
datacenter, so the uniq and the sed are not needed. As I said, leftovers from 
prior work)

Re: [Gnuplot-info] problem with legend in svg pie-chart

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

Doing some more digging, I'm finding that the colors used for the key legend are 
not the colors used for the linetype definitions that are used to make the graph

I changed the lines to
set linetype 1 lc "purple" lw 5 pt 3 ps 3
set linetype 2 lc "green" lw 5 pt 3 ps 3
set linetype 3 lc "yellow" lw 5 pt 3 ps 3
set linetype 4 lc "blue" lw 5 pt 3 ps 3
set linetype 5 lc "orange" lw 5 pt 3 ps 3
set linetype 6 lc "red" lw 5 pt 3 ps 3
set linetype 7 lc "brown" lw 5 pt 3 ps 3
set linetype 8 lc "gold" lw 5 pt 3 ps 3
set linetype 9 lc "cyan" lw 5 pt 3 ps 3
set multiplot

plot for [i=4:6] "site_summary.data" u (x+column(0)*250):(y):(r):(360*(sum 
[col=4:(i-1)] column(col))/(sum [col=4:6] column(col))):(360*(sum [col=4:i] 
column(col))/(sum [col=4:6] column(col))):(i) title columnhead(i) with circles 
lc var

and while the pie segments are blue, orange, and red. the legend colors are 
brown, gold, gold

so why is the key showing different color codes than what was used to make the 
graphs

and why is color 8 used twice?

Just a minor point: "uniq" works best with sorted input (or use "sort 
-u").  And why are you appending a blank to each line?

[Gnuplot-info] problem with legend in svg pie-chart

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

I'm using the following script to generate pie charts for each line in a file. 
The problem is that the legend at the bottom ends up just having three solid 
black circles instead of colored circles.

I'm using gnuplot v5.0 (compiled from source)

What can I do to fix this?


linecount = "`cut -f 1 -d '|' site_summary.data |uniq| sed s/$/' '/ |wc -l`"
sitecount = value("linecount")-1
set term svg size (sitecount * 250),300 dynamic noenhanced
unset tics
unset border
unset colorbox
set key autotitle columnheader
set key center bottom horizontal samplen 5
set xrange [-(125*sitecount):(125*sitecount)]
set yrange [-150:150]
set angles degree
x=0

r=100.0

Version 5 is different in a lot of ways.
Hence the bump in major version from 4.* to 5.0

Read the Release Notes, the "What's New" section in the User Manual, etc.

All this and more available to browse on

[Gnuplot-info] Suggestion for "test" command

[Dave H. <da...@ho...>]

Could it be made to show the version of Gnuplot, so that the various 
outputs can be readily compared?

[Gnuplot-info] Gnuplot 4.6 -> 5.0 diffs

[Dave H. <da...@ho...>]

Mac OS/X, Yosemite 10.10.2.

Is there a guide to what changed in Gnuplot 5?  I was wondering why my 
default colours changed e.g. "lt 1" used to be red, and is now a sort of 
purple.

I discovered this after restarting the Mac; I had changed the order of 
plots on one graph, restarted the Mac following a network problem, plotted 
an unrelated graph, and noticed it.  In the meantime I must've done quite 
a few updates to Macports, whilst keeping a Gnuplot window open all the 
while (silly me).

I didn't know I was running Gnuplot 5.0.0 until just now, when I went to 
confirm the version (I think it used to be 4.6.5 or something).

Comparing the result of "test" with an old one that I'd printed (and 
laminated), there's a few small differences such as points now being black 
instead of the line colour and pattern fill "9" has disappeared, but the 
colours have changed somewhat, for no apparent good reason.

As a result I know have to change *all* of my scripts, except in those 
cases where I was using RGB colours.

So, what little surprises may I expect in 5.0?

[Gnuplot-info] Meaning of "fit ... error"

[Philipp K. J. <ja...@ie...>]

I am having difficulties understanding the
precise meaning of the "error" facility 
within the fit command. Can someone clarify?

1) The documentation mentions three "keywords":
	zerror
	yerror
	error z
Are the synonyms? Or are there semantic 
differences? Is "error z" a fixed phrase,
or is it also possible to have "error x"
or something like that?

2) In the demos I found an example using
"xyerror", which is not mentioned in the
docs. What does that do? How does weighting
the x-values enter into the calculation of
the error (=SSR)?

3) What does the presence of zerror actually
tell me (or gnuplot)? Is it correct to say 
that WITH "zerror" the last entry in the 
"using" spec is interpreted as the error 
column, whereas with "noerror", the last 
column is interpreted as the "y-value", and 
errors (=weights) are set equal to 1? Are
there exceptions to this rule?
