[clnuplot-devel] common-lisp.net darcs link
by david thompson 21 Jul '09

The darcs download directions on common-lisp.net may be in need of clarification: darcs get http://common-lisp.net/project/clnuplot gives me an error. However, darcs get http://common-lisp.net/project/clnuplot/darcs seems to work fine. - Alan

[clnuplot-devel] patch: xticlabels for box plot
by david thompson 21 Jul '09

21 Jul '09

Thanks for putting together CLNUPLOT. I had some interest in putting labels on the x axis with a box plot -- i.e., being able to do something like CLNUPLOT> (write-plot (clnuplot:make-plot :bar '((1 2 "a") (2 2.5 "b") (3 3.1 "c")) :linewidth 3.0 :key "off" :filename "bar12" :xlabel "Bin Number" :ylabel "Dance Partners" :x-coord #'first :y-coord #'second :title "Bin Number versus Dance Partners" :ymin 0.0) :postscript) #<GNUPLOT {B5EFB49}> CLNUPLOT> If interested, the attached diff should support the above syntax... The main changes: - extending the data points for the box plot type so that there is a fourth 'column', the label column - altering the plot command to use xticlabels Thanks again, Alan

[clnuplot-devel] Error using exponential notation?
by Olav Fossgaard 11 Feb '09

11 Feb '09

|There seems to be a bug plotting small numbers using exponential notation. For example: (clnuplot:write-plot (clnuplot:make-plot :lines-points '((1 0.10) (2 3.0E-5) (3 4.0E-5)) :pointsize 2.0 :linewidth 3.0 :filename "simple-example" :xlabel "foo" :ylabel "bar" :x-coord #'first :y-coord #'second :title "foobar" :ymin 0.0) :pdf) The plotted points are ((1 0.10) (2 3) (3 4)), and it seems the exponential parts are ignored. However, if we increase the exponents a couple of orders of magnitude (replace E-5 with E-3), the points are plotted correctly. Olav Fossgaard|

[clnuplot-devel] followup: specifying arbitrary output file location
by david thompson 09 Feb '09

09 Feb '09

It would give users even more flexibility if they had the capability not only to explicitly define the location of the gnuplot 'data' file ( http://common-lisp.net/pipermail/clnuplot-devel/2009-February/000008.html) but to also have the capability to explicitly specify the location of the rendered (graphical) version of the chart/plot. Something like (defun fullname-rendered (plot type) (let ((fullpath (fullpath plot))) (namestring (make-pathname ;; strip type info :name (pathname-name fullpath) :directory (pathname-directory fullpath) :type type)))) and then a modification of each 'set output' line for gnuplot (in the various WRITE-PLOT definitions) to something like (format out "set output '~A'~C" (fullname-rendered plot "ps") #\Linefeed)) seems like it would do the trick... - Alan

[clnuplot-devel] patch: specifying arbitrary output file location
by david thompson 08 Feb '09

08 Feb '09

There may be circumstances when it is desirable to specify the output location of the gnuplot file in a direct fashion (the current code uses ASDF to determine the output file location). The attached patch (hopefully...) allows the user to specify an arbitrary location for the gnuplot file output by WRITE-PLOT. Examples: CLNUPLOT> (clnuplot:write-plot (clnuplot:make-plot :bar '((1 2) (2 2.5) (3 3.1) (4 3.4) (5 4.2)) :linewidth 3.0 :filename "bar123" :pathdir "/tmp/" :xlabel "Bin Number" :ylabel "Dance Partners" :x-coord #'first :y-coord #'second :title "Bin Number versus Dance Partners" :ymin 0.0) :postscript) #<GNUPLOT {B5FE309}> CLNUPLOT> (fullpath #<GNUPLOT {B5FE309}>) #P"/tmp/bar123.data" or CLNUPLOT> (clnuplot:write-plot (clnuplot:make-plot :bar '((1 2) (2 2.5) (3 3.1) (4 3.4) (5 4.2)) :linewidth 3.0 :filename "bar123" :pathdir (make-pathname :directory '(:absolute "tmp")) :xlabel "Bin Number" :ylabel "Dance Partners" :x-coord #'first :y-coord #'second :title "Bin Number versus Dance Partners" :ymin 0.0) :postscript) #<GNUPLOT {B0A4D99}> CLNUPLOT> (fullpath #<GNUPLOT {B0A4D99}>) #P"/tmp/bar123.data" The original behavior of WRITE-PLOT seems to still be there: CLNUPLOT> (clnuplot:write-plot (clnuplot:make-plot :bar '((1 2) (2 2.5) (3 3.1) (4 3.4) (5 4.2)) :linewidth 3.0 :filename "bar123" :xlabel "Bin Number" :ylabel "Dance Partners" :x-coord #'first :y-coord #'second :title "Bin Number versus Dance Partners" :ymin 0.0) :postscript) #<GNUPLOT {AC0DA99}> CLNUPLOT> (fullpath #<GNUPLOT {AC0DA99}>) #P"/root/.sbcl/site/clnuplot/plots/bar123.data" - Alan
