<h2>Ploticus 2.31 - 5 Feb '05 - New features</h2>
<ul>
<li> <b>datematic</b> - when working with date, datetime, or time data,
datematic will automatically determine a reasonable default axis range, stub format, stub increment,
and will enable <tt>autoyears</tt>, <tt>automonths</tt>, or <tt>autodays</tt> as appropriate.
In <a href="axis.html">proc axis</a> this is used by specifying <tt>stubs: datematic</tt>.
In proc areadef <a href="autorange.html">autorange</a>, it is used by specifying <tt>nearest=datematic</tt>.
<br>
Example:
<pre>
#proc areadef
xautorange: datafield=1 nearest=datematic
xaxis.stubs: datematic
...
</pre>
<br><br>
<li> <a href="autorange.html">autorange</a> - lots of new <tt>nearest</tt> options
<br><br>
<li> 64 bit Linux supported. Version 2.31 compiles and runs on AMD64.
The source code now gives an (almost) clean -Wall compile .
<br><br>
<li> <a href="lineplot.html">lineplot</a> - new feature - <tt>gapmissing: auto</tt>
detects omitted data points without requiring missing data codes be present..
heuristic is based on interval between 1st 2 data points.
<br><br>
<li> <a href="pl.1.html">pl command line</a> - new option <tt>-noshell</tt> disables
all internal shell invocations, useful ie. when testing a script from a non-trusted source.
<br><br>
<li> <a href="axis.html">proc axis</a> - new features <tt>stubs: minonly</tt>, <tt>stubs: maxonly</tt>, and
<tt>stubs: minmaxonly</tt> to render stubs only at the axis minima, maxima, or both.
<br><br>
<li> <a href="axis.html">proc axis</a> - new attribute - <tt>arrow</tt> for placing an arrowhead at the axis maxima.
<br><br>
<li> <a href="line.html">proc line</a> - new attribute <tt>anchor</tt> allows drawing relative
a figure relative to an anchor location (useful when drawing the same figure repeatedly
in different locations).
<br><br>
<li> <a href="axis.html">proc axis</a> - new attribute <tt>nolimit</tt> that can be used to disable
the axis drawing "circuit breaker" for those special cases where it is a hinderance.
<br><br>
<li> <a href="processdata.html">proc processdata</a> - action:stats - can now produce one set of
stats based one or several data fields (values all taken together).
<br><br>
<li> clickmap is now automatically disabled in direct cgi mode, since it's not applicable there.
<br><br>
<li> <a href="page.html">proc page</a> - new attributes <tt>map</tt> and <tt>csmap</tt> - allow clickmap
generation to be turned on from within a script instead of on the command line.
<br><br>
<li> win32 - when PNG/GIF/JPEG image output is written to stdout, stdout should now be set to the
appropriate coding.
<br><br>
<li> proc rect - to get no fill color you can now say <tt>color: none</tt> (used to have to say just <tt>color:</tt> )
</ul>
<br>
<br>
<br>
<h2>Bug fixes</h2>
<ul>
<li> due to a Makefile problem (pl command only) no imagemap output was produced with
-map or -csmap when producing gif, png, or jpeg. libploticus unaffected.
<a href="http://groups.yahoo.com/group/ploticus/message/1244">More info here</a>.
<br><br>
<li> dates - bug involving incorrect day-of-week computation.
Plots that used <tt>omitweekends</tt> omitted the wrong days of the week.
<br><br>
<li> proc curvefit - wasn't discarding input data points where Y component was a non-numeric
(eg. a missing data code).
<br><br>
<li> very long category names used as axis labels.. some long labels were being omitted on axis..
<br><br>
<li> autorange - big datafield list using fieldnames, was causing overflow
<br><br>
<li> arrow color sometimes incorrect - fixed
<br><br>
<li> in X mode, the yellow [End.] or [more..] button is not affected by <tt>-scale</tt>
<br><br>
<li> bounding box incorrect with vertical text when a <tt>-scale</tt> was set
<br><br>
<li> proc usedata - was giving error when current data set was the original data set; also made more lenient on the "original" name
<br><br>
<li> svg - "bad CSS property or descriptor declaration" error - fixed (?)
<br><br>
<li> font names w/ embedded spaces - these are parsed correctly everywhere (-font, proc page, proc settings, textdetails font=)
but these are problematic with some drivers.. SWF definitely won't handle these.
In a test, GD/Truetype doesn't seem to work with them either. Not sure about SVG.
