Subject: [clnuplot-devel] patch: specifying arbitrary output file location
Message-ID: <c1a665c30902072304p5516a005g6f821fa670ed9714@mail.gmail.com>

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"

Subject: [clnuplot-devel] followup: specifying arbitrary output file location
Message-ID: <c1a665c30902090805r41e8fc6cjd77508d011103630@mail.gmail.com>

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...

Hi David (Alan?).

good idea. I'll add this sometime this week.

Subject: [clnuplot-devel] Error using exponential notation?
Message-ID: <499315A9.4000404@gmail.com>

|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.
