gnuplot development

more elaborate object specification:

set object 1 circle at 0,0 size 0.4 fc rgb "red" fs transparent solid 
0.3 border lc rgb "blue" lw 3.0

For me, too. 

Which is not good. lt 0 should be a minimally dotted line.

Are all these options documented somewhere?
Neither help object, nor help circle seem to
produce information on "border", for instance.

"help fillstyle" gives some info.

Thanks.

Hi James

does the demo http://gnuplot.sourceforge.net/demo/heatmaps.html explain 
what you are looking for? see last two examples.

Argh.  I missed that.

I thought I had tried using 1:2:3:4, but perhaps only with the existing files
(which lack blank lines; they are just lists of points).

I take it then that all I need to do is to sort the files to create iso-lines
and add blanks between those, yes?

Sort(1) should handle the sorting; I'll just need to write a simple program
which adds a blank line whenever a specified column changes value.

Thanks.

for the last two examples at 
http://gnuplot.sourceforge.net/demo/heatmaps.html, i think the "splot" 
command needs an argument of 1:2:3:4 which is a regular grid of 
parameter 3 and parameter 4 at 1:2, with no blank lines.

other important instructions are:
set pm3d ...
set view ...
set contour ...

the examples are straightforward and understandable but very concise so 
be careful.

Not really.  It just does exactly what you asked it to.  So whatever 
madness may have ensued: it was caused by you.

What did you expect to happen when you added "xticslabels(1)", other 
than what the documentation clearly says it does: put a tick label at 
every data point?  On what basis did you conclude this would be a useful 
thing to do in this use case?

> How can I force gnuplot to thin textual labels out?

Only by thinning out the data.  See "every".

This works for the most part:

plot DATAFILE using 4:1:5:(0):3:ytic(2)  with vectors notitle nohead lc
palette

but still wondering if there is a why to the the whole line style and not
just the color (so I could change widths or ps based on data)

Thanks.
