Dear supporters,
again thanks for the great support.
One thing I am missing (or simply not understanding) is 3dplotting
without automatically scaled up range of the function value.
(This is just my first example at hand and surely not a good one:
y, x = var ('x,y')
plot3d(lambda x,y : (bessel_Y(y,x,"scipy",53)).real(), (-0.002,0.002),
(-1,1))
#Put some broader x-range in to see what I mean.)
Please excuse this sloppy written description: Jmol and Sage seem to
try to plot the whole graph even at singularities, then "give up" (at
a level I don't know how to fix) but leave the picture with the scaled
up value range.
Use this link to see what I mean would be useful sometimes (and please
do not blame me because my plot above is another thing as seen there -
I am just playing around and I just took the first example at hand):
http://mathworld.wolfram.com/ModifiedBesselFunctionoftheSecondKind.html
There the value range is simply cut at some point. In the german
wikipedia article on the exponential function it is done in a similar
way by Maple and the whole picture is scaled equally in all
dimensions:
http://de.wikipedia.org/w/index.php?title=Datei:Exp_re.png&filetimestamp=20050215210532
(Put the two lines together without intermedate space.)
Is there a way to limit the value range in a 3dplot other than
limiting the input range (I want to see, say, the region around the
singularity)?
Yours, littlemathteacher
