I have a file 'test.data' having the following data:
0 0 "no yes"
1 3 "yes no"
4 6 "th"
7 9 "fo"
I can run gnuplot command from linux:
plot 'test.data' using 1:2:3 with labels hypertext point pt 7
It works with the mouse over showing the hypertext from 3rd column. But when I use svg as term, the hypertext doesn't show.
set term svg mouse jsdir "http://.../TEST/"
set output "test.svg"
plot 'test.data' using 1:2:3 with labels hypertext point pt 7
The I load http://.../TEST/test.svg
It plots the data but no hypertext. Please help! Thanks!
(I also tried adding, set label at 4,6 "th" hypertext point pt 1)

I would like only the title in the legent without point.
When I plot yerrorbar, there is an error:
duplicated or contradicting arguments in plot options

If something is missing in my question, let me know please.
In recent gnuplot versions there is a separate option keyentry (introduced in version 5.2.6).
The documentation says
gnuplot> help keyentry
Normally each plot autogenerates a single line entry in the key. If you need
more control over what appears in the key you can use the `keyentry` keyword
in the `plot` or `splot` command to insert extra lines. Instead of providing
a filename or function to plot, use `keyentry` as a placeholder followed by
plot style information (used to generate a key symbol) and a title.
Example
set key box width 3
plot 'file.txt' with points pt 7 notitle, keyentry title "Some Title"
In older gnuplot versions a work-around is to plot some function that lies entirely outside the plot and give it the desired title. This may generate warning messages such as "all points out of range" but it does place the title in the key. Example below. Note that the pointtype is given as an empty string.
set yrange [0:*]
plot 'file.txt' with points pt 7 notitle, -1 with points pt '' title "Some Title"
Is there a easy way to get points with black outline in gnuplot? I'm using standard color filled point types, for example:
set style line 3 lc rgb '#4682B4' pt 9 ps 0.65
but I need to make sure that the plot will be easily readable in black & white version too. Black outlines would help, how can I add them?
The simplest "quick and dirty" solution that comes to mind is to plot the data set twice, once with the full symbol style and then with an empty symbol style. For instance:
plot "temp" pt 9 ps 2, "temp" pt 8 ps 2 lc 0 lw 2
I'm trying to get a linespoints plot with the points being hypertext. So far, I've managed to get linespoints working but without hypertext and I've split it into two plots overlaid, one with lines one with hypertext points. While the second "works", it results in an extra key for the points. Ideally, I want linespoints key entries for each line and points combination, not a line key and a points key.
That may be possible with a bit cheating. Usually the hypertext is shown only if also points is set. Since the area which is active for the hypertext depends on the point size, you can draw all points with linespoints and then use a transparent point when plotting the labels:
set samples 11
set xrange [0:10]
plot '+' using 1:1:1 with linespoints pt 7 ps var title 'mytitle',\
'+' using 1:1:(sprintf('(%d,%d)', $1, $1)):1 with labels hypertext point pt 7 lc rgb '#ff000000' notitle
Note for other users: The hypertext option was introduced in version 5.0.
In the official document in page 44 it says, to draw a boxplot
# Place a boxplot at x coordinate 1.0 representing the y values in column 5
plot 'data' using (1.0):5
I cannot get it work, when I do above gnuplot only draws points, not a box. Anybody knows how to do it? In the guide, the example shows a box plot (page 44 the figure on the right)
I am using gnuplot 4.6 patch level 4. I am not getting any errors, but the box is just not there.
When I use the demo script
plot 'silver.dat' using (1):2, '' using (2):(5*$3)
it works, what does the second part after the comma mean? ( '' using (2):(5*$3) )
I was specifying box widths, but finally found that this should be added at least
set style data boxplot
optionally, you can add
set style fill solid 0.25 border -1
set style boxplot outliers pointtype 7
How to change point size and shape and color in gnuplot.
plot "./points.dat" using 1:2 title with dots
I am using above command to plot graph ,but it shows very small size points.
I tried to use command
set pointsize 20
but still point size is same.
Use the pointtype and pointsize options, e.g.
plot "./points.dat" using 1:2 pt 7 ps 10
where pt 7 gives you a filled circle and ps 10 is the size.
See: Plotting data.
The pointsize command scales the size of points, but does not affect the size of dots.
In other words, plot ... with points ps 2 will generate points of twice the normal size, but for plot ... with dots ps 2 the "ps 2" part is ignored.
You could use circular points (pt 7), which look just like dots.
