Hi IDL gurus,
One more time an iTools question...
I am getting very confused. I simply try to plot one value in a polar
plot. However, it appeared that this didn't work, whatever azimuth
value chosen. Using a 2-value array was even more mysterious On
IDL6.3, a little playing with some arbitrary chosen R & azimuth values
resulted in the following:
R=[25,30]; arbitrary zenith
Rmax=50
Azi=[200,230]*!DtoR; arbitrary azimuth
iplot, R, Azi, /POLAR, linestyle=6, sym_index=7,$
XRANGE=[-Rmax,Rmax], YRANGE=[-Rmax,Rmax], /no_saveprompt
..nothing is shown (?)
but when using Azi=[210,230]*!DtoR
... one 'x' is shown (??)
and when using Azi=[280,230]*!DtoR
... the two 'x' are shown (???)
Has anybody an explanation for this odd behavior? An moreover, how do
I manage to plot just one point on a polar plot?
(ps, A string, like ixyouts in polar coordinates would even be
better.)
a troubled itools user
