pyPloticus is a python wrapper for libploticus. On my Mandriva 2009.1 system I
was having trouble with an undefined symbol error after compiling libploticus
2.41 and then installing pyPloticus. It all compiled and installed OK but on
importing the python module from inside the python interpreter I would get and
"undefined symbol PLGG_pixpt" error.

A small change to the ploticus Makefile has fixed this. As Steve says in his
Makefile the shared library part of the Makefile hasn't been tested - well on
Mandriva 2009.1 at least, it now has.

The key changes to Makefile are

1. Select option 5 by commenting out line 28 (option 1) and uncommenting lines
74 to 78.
2. Lines 223 to 226 should look like this
libploticus-static: $(OBJ) api.o gd00files gd16files
	 $(RMCOM) libploticus.$(LIBEXT)
	 $(ARCOM) libploticus.$(LIBEXT) $(OBJ) api.o $(GD16) $(GD)
3. Add $(FPIC) to the compilation of gd00files and gd16files
gd00files:
	 $(CC) $(FPIC) -I./gd13 -I./ -c gdfontg.c gdfontl.c gdfontmb.c gdfonts.c
gdfontt.c
	 echo "done with gd00files" > gd00files
gd16files:
	 $(CC) -c $(WALL) $(FPIC) grgd.c -DGD16 -DPLOTICUS -I./ -I./gd16 -o grgd16.o
	 $(CC) -c $(CFLAGS) $(FPIC) devstuff.c -DGD16 -o devstuff16.o
	 $(CC) -c $(FPIC) -I./gd16 -I./ $(GD16H) gd16.c gd_io.c gd_io_dp.c gd_io_file.c
gd_png.c
	 echo "done with gd16files" > gd16files

4. Now "make clean" then "make"
5. Copy your squeaky new libploticus.a file to /usr/lib (or if like me you have
a 64 bit machine then /usr/lib64) but in the process rename the file to
libploticus.so.0.0 (you have actually created a shared library but I think
pyPloticus compilation expects a file with a ".a" extension).
6. Run ldconfig -n /usr/lib (ldconfig -n /usr/lib64 for 64 bitters)
7. You can now go to pyPloticus and first edit the setup.py file changing the
plot_src_path to point to the location of the newly created libploticus.a file
(something like plot_src_path="../pl241src/src/")
8. Run "python setup.py install"

You should now have it all set to go.
Testing
1. Start the python interpreter "python"
2. try to import the ploticus module "import ploticus"
You should get no errors at this point
3. You can now try the pyPloticus examples "python plot.py graph.html"
I get some errors listed but the graph srcc.png still get produced.

Hope this help someone please tell me if you have other errors of if this works
for you.

Thanks!  I'll include these notes, and the FPIC Makefile mods  in the next
release. -Steve

I used the second prefab dist example in the handbook as a reference:

	 http://ploticus.sourceforge.net/doc/prefab_dist_ex.html

and created my own histogram. My labels do not look like those in the
example. Specifically, while the bin labels are written vertically,
the individual
letters are horizontal . In other words my labels look like this:

l
a
b
e
l

Any idea why this would be so and how to fix it? The letters in the
Y-axis label have the same problem. Note that I do not have this
problem if I produce a GIF file -- I only see it if my output is an
X window.

Hi,

I am using ploticus 2.32 with the lines prefab to graph network bandwidth use. 
The numbers involved have many digits, typically 6 or 7.  By default ploticus is
not inserting commas into the Y axis stubs, which makes it hard to easily read,
since you have to slow down and count zeros to understand what the chart is
saying.

Is there a way to force ploticus to use commas?  Or to make it divide the
numbers it's charting by 1000?

Thanks!


-Travis

Hello Josh,

short answer - you are getting the expected behavior

ploticus uses native x11 fonts, and x11 doesn't support vertical text.

Hi,
i'm looking for a simple way to draw arrays directly in png format. I thought a
"proc array" would exist in Ploticus but i didn't find it. I tried to do it with
"proc bars" but it doesn't go well for variable width of columns based on text
length and other customisable items...
Does anybody have ideas ?
Thanks
dp

Hello,

use something like this:   yinc="100 1000"

this should put a stub every 100,000  but show numbers in the 100's (native
value divided by 1000)... you then ould need to label the yaxis by saying eg.
"counts (in thousands)"

Is there a way (using prefabs) to create a bubble plot which is essentially a
scatterplot in which the plotting symbol diameter or area is proportional to a
third variable?  Maybe a better way to think about it is a heatmap where the 
"contentfield" contains
the variable that controls the plot symbol size, and instead of
'colorlist', something like 'pltsymsizelist' provides the mapping between the 
'cutofflist' and the "contentfield".


What might even be cooler is a stick as the plotting symbol with the height of
the stick related to "contentfield" magnitude so the graph would be quasi-3d.

have a look at http://www.thregr.org/~wavexx/software/trend/

or you might be able to modify
http://gapcmon.sourceforge.net/

( I know this group is for ploticus, but sometimes the most elegant solution is
the fastest one )

Hello,

The underlying engine has this capability but the scat prefab does not.  You can
easily add it... go into your ./prefabs directory and edit scat.pl... and add
lines 209, 210, and 211 as shown below.

    198  //// do the data points last so they are on top of the rest of the
stuff..
    199  #proc scatterplot
    200  xfield: @x
    201  yfield: @y
    202  symbol: shape=@ptshape style=@ptstyle radius=@ptsize color=@ptcolor
    203  #ifspec clickmapurl
    204  #ifspec clickmaplabel
    205  legendlabel: @name
    206  #ifspec ptselect select
    207  #ifspec cluster
    208  // the following 3 added scg 8/13/09
    209  #ifspec sizefield
    210  #ifspec sizescale
    211  #ifspec colorfield

Then use pl -prefab scat ... sizefield=... and sizescale=... on your prefab
command line.

-----------

sizefield      dfield

     If specified, the size of data point symbols, lines, or text are controlled
by this data field, effectively allowing another variable to be presented. For
symbols or text the value in dfield will be taken to be a character point size
(see also sizescale). For line segments, the value in dfield will scale the
length of the lines, ie. a data value of 2.0 doubles it and 0.5 halves it.

sizescale     n

     May be used with sizefield when the size of data point symbols or text is
being controlled by a datafield. This attribute may be used to scale the size of
the point symbols to the desired range. Scaling is based on symbol area rather
than diameter. A value of 2.0 doubles the resulting size; 0.5 halves it.

colorfield dfield

     If specified, the color of data point symbols, lines, text, or rectangles is
controlled by this data field, effectively allowing another variable to be
presented. The data field should contain color specifications. (New in 2.41)

Hello Ben,

I tried your example and the colors seem to work here, using x11 and image
output formats... see attached img.

echo "3 3 20.45 black
5 1 1.00 blue
0 2 40.66 black
1 1 7.63 black
2 0 8.27 black
1 3 20.80 black
2 2 7.86 black" |
pl -gif -prefab scat data=stdin x=1 y=2 sizefield=3 \
colorfield=4 \
rectangle=" 1.05 1.15 4.15 5.25" \
sizescale="1" \
xrange="-1.0 5 " yrange="-1.0 5 "


?

Is ps/eps output incompatible with colorfield?  I searched and did not yet find
that restriction.

I am making a concept chart using the #proc annotate method based on the "simple
E-R diagram" example on http://ploticus.sourceforge.net/doc/clickmap.html

When I add several concepts wide, the image seems to truncate at x=1024 (any
backingbox, or text stops at 1024). Is there an easy way around this? Even 1280x
would help.

I have messed with the -scale to get it to fit, but the font gets very small.

Hello,

did you try increasing -pagesize ?

Hello,

Are you able to get the desired results if you produce an img?  If so, then it
indicates that the problem may be specific to ps/eps.  Let me know, meanwhile I
will set up a test when I have the chance.

Steve

Thanks.  I experimented with the pagesize option and found that I need to
increase the pixsize option appropriately to make it all work out pretty.

In my case, -pagesize 13,6  -pixsize 1220,500  works.  I obviously need to
re-read the explanation of those parameters so I don't have to use brute-force
experimentation to get it right.
Thanks

Hi folks! I respectfully submit the following patch for the next release of
ploticus. It makes some super-trivial but useful changes to a prefab script.

We use chron prefabs to create "mrtg-style" network graphs every 5 minutes. We
use "xnearest=exact" so that we dont have these disconcerting "gaps" at the
start and end of our graph. However, this means that the first stub says "00"
even though it's actually "00:15"... and we don't want to change the stub format
to display minutes.

The right way to solve this is to use "stubround", but the current prefabs don't
allow passing that through. The current patch solves this with only two
additional lines.

Hello everyone,

I want to generate a gif-file using 'proc scatterplot'. Further I want to use
the clickmap-mouseover-feature of ploticus, so that a label appears when moving
the mouse-pointer over a datapoint of the plot, like it is described. This label
should contain further information concerning the datapoint. E.g. I have
following data in a file (<perl_out_msg.txt>):
<15 1 18082009 16:45 P 193.500 193.500 mA>. On xaxis datetime is set (using 3rd
and 4th entry of file), on yaxis the value is set (using 7th entry , and 5th
entry for the data-driven appearance of val). Now I want to give in the
(clickmap)label the value of the 2nd entry of the file, like following (part of
ploticus-script <board_val.pl> ):
...
#proc getdata
file: perl_out_data/perl_out_msg.txt
delimit: space
pf_fieldnames: datetime nbytes res nr
filter:
 	 ##set TIME = @@4
	 @@3.@@TIME @@7 @@5 @@2
...
#proc legendentry
sampletype: symbol
tag: P
details: shape=square radius=0.04 style=filled fillcolor=green
label: P

#proc scatterplot
xfield: datetime
yfield: nbytes
symfield: res
clickmaplabel: nr
...

When I run batch with cmd

"..\pl" -gif ploticus_scripts\board_val.pl -csmap -mapfile stdout

I get the plot/gif-file, but the mouseoverlabel doesn't work. Following messages
are given:
<area shape="rect" nohref coords="998,213,1006,221" title="nr" alt="nr"  />

What do I make wrong/forget ?
There seems to be missing the reference ?
I tried already to set up "white" bars, but this didn't work either.
Or is clickmaplabel not intended to work with scatterplot as I want ?

Thanks a lot,

best regards,
Berthold

I am a musician tracking my daily practice time in four categories.  I would
like to have a graph that represents one day's practice as a stacked bar
totalling up each category.  The data looks like this

<date>  <cat1>  <cat2>  <cat3>  <cat4>
090918    .3           .1         1.1        .6
090919     0           .5           0         .1
.
.
.

I'm getting close to what I want with this command:

ploticus -png -prefab stack  data=/data/personal/prac_data.dat  y=2 y2=3
y3=4 y4=5  color=red  tab=day  title="Hours of practice per day" name="Cat1"
name2="Cat2" name3="Cat3" name4="Cat4" -o /tmp/ploticus_stacked_graph.png

which generates this:
http://onensemble.org/krisShare/ploticus_stacked_graph.png

But as you can see, the x-axis text is overlapping and unreadable.

Is there some way to either fix the dates, or remove all x-axis labels
entirely?

Thank you in advance for any advice you're able to provide.

Kris

ploticus,

Trying to make the world's simplest bar graph here, with this script:

#proc getdata
file:  wine.dat
showdata: yes
delim: whitespace
fieldnames: wine score

#proc areadef
title: Wine Scores
rectangle: 1 1 5 2
//xrange: 0 30
//yrange: 0 4
xautorange: datafield=wine
yautorange: datafield=score
yaxis.stubs: incremental 1

#proc bars
lenfield: 1
//color: rgb(.8,1,.7)
//longwayslabel: yes
//labeldetails: align=R adjust=0,-0.1

When I run it I see:

1026 ~/tmp>pl -png winebars.pl
// proc getdata has read & parsed these data:
// field names are: wine|score|
Wine:1|3|
Wine:2|2|

Wine:27|3|
Wine:28|4|
Wine:29|1|
Wine:30|2|
// end of data set
pl proc areadef: error 5709: autorange: all data out of range

And the resulting *png has a y axis with 1,2,3,4, no x axis and no bars. I've a
few different variations - what am I missing?

Thanks again,
