Hello,
I am trying to draw a 3D contour plot using the following Fortran code:
call PLPARSEOPTS( PL_PARSE_FULL )
call PLSFNAM( 'main_heat.png' )
call PLSDEV( 'pngcairo' )
call PLINIT( )
call PLW3D( 1.0_rp, 1.0_rp, 1.0_rp, 0.0_rp, real( size, kind = rp ), &
0.0_rp, real( size, kind = rp ), &
0.0_rp, 100.0_rp, 90.0_rp, 0.0_rp )
call PLOT3D( x, y, A, DRAW_LINEXY, .true. )
call PLEND( )
However, when I execute my code, I get the following runtime error messages:
*** PLPLOT ERROR, ABORTING OPERATION ***
plw3d: Please set up 2-d window first, aborting operation
*** PLPLOT ERROR, ABORTING OPERATION ***
The documentation for PLW3D doesn't mention that I need to call other
subroutines. Any help will be greatly appreciated.
Cheers,
Wadud.
