svn trunk has a new plotting facility that includes a scheme api
similar to the (gnuplot ...) function in CM2. the new plotter window
is much improved and simplified (it now looks bascially like the x-
windows gui i had in cm2...)
Plot windows can display/edit multiple layers of points, each with
their own color and style.
Points can have more than 2 fields of data (ie arities greater than 2 )
Plots can be saved to disk. Plot files store contents in XML data so
you can edit these too.
WIndow: Control-click adds points, Delete key delete points, Click-
Drag on axis to zoom
The (plot ...) function opens a new window with data you pass to it
The (plot-data ...) function returns data from an open plot window
back to scheme
Documentation is in: cm/res/doc/cm.html#plotting
(plot :title "Hi Ho!" '(0 0 .25 1 .75 1 1 0) '(0 0 1 1))
<plot title="Hi Ho!>
<axis name="x" range=" 0 1 0.25 5"/>
<axis name="y" range=" 0 1 0.25 5"/>
<points title="Layer 1" style="lineandpoint"
color="ffff0000"><point>0.00 0.00</point><point>0.25 1.00</
point><point>0.75 1.00</point><point>1.00 0.00</point></points>
<points title="Layer 2" style="lineandpoint"
color="ff008000"><point>0.00 0.00</point><point>1.00 1.00</point></
the easiest way to see how it works is to try out the new examples in
the Help menu: Help>Examples>Plotting
todo next weeks: sonification of point sets, axis and layer
I plan on making a major binary release of CM3 in about two weeks
including support for the new C version of Fomus that David Psenicka
has been working on the past year.
