I have little routine to plot a compass circle and a line showing the
heading to a radio source. I want to plot the letters N, E, S, W and a
legend giving the distance to the source. Here's a bit of the code:
xc=. }: 1p1*int01 2000
sx=. 0.85*sin xc
cx=. 0.85*cos xc
pd 'reset'
pd options
pd 'titlefont Arial 16 Bold'
pd sx;cx
pd (-sx);cx
headx=. 0.9*sin y
heady=. 0.9*cos y
pd 'pensize 5;color red'
pd (0,headx);(0,heady)
pd 'textfont Arial 14 Bold' NB. this has no effect
pd 'textcolor green'
pd 'text _0.03p 0.97p N'
pd 'text _0.03p _0.97p S'
pd 'text 0.93p 0p E'
pd 'text _1p 0p W'
pd 'textcolor blue'
T=. '350 700 Distance to beacon ',(":x),' miles.'
pd 'text ',T
pd 'pdf'
The problem is with the line (copied from the wiki)
pd 'textfont Arial 14 Bold'
The font type or size can be set to anything and there is no change in the
text on the plot. The titlefont command works as expected.
The situation is the same for j807, j901 &j902 on my Mac and under
Ubuntu linux.
Any suggestions would be appreciated.
