[Plplot-general] A Quick question about plline()

[Yuan, F. <fan...@tt...>]

I installed plplot11 in Ubuntu 11.10.

I use plline() in the subroutine xy_plt1 of  "gsa.h" file, they keep warned me as follows:

./gsa.h: In function ‘xy_plt1’:
./gsa.h:167:4: warning: passing argument 2 of ‘c_plline’ from incompatible pointer type [enabled by default]
/usr/include/plplot/plplot.h:1260:1: note: expected ‘const PLFLT *’ but argument is of type ‘float *’
./gsa.h:167:4: warning: passing argument 3 of ‘c_plline’ from incompatible pointer type [enabled by default]
/usr/include/plplot/plplot.h:1260:1: note: expected ‘const PLFLT *’ but argument is of type ‘float *’


 void    xy_plt1 ( int nn, float xn[], float yn[])

The commends I used in plline is:
plline( nn, xn, yn);

The plline only draw one string line.

Does anyone know how to fix it?
