[Plplot-general] Problem with error bars (segfault)

[Tiago P. <tm...@me...>]

Hi there,

	I've been using plplot for a few weeks. Today I tried to include
error bars in a plot, without much success. Every call that I make to
plerry ends up invariably in a Segmentation Fault. I have tried to do some
simpler tests to plerry, but the result is always the same. Is
plerry/plerrx working? Could anybody post a working example?
	I am calling plerry in the following manner (python syntax):

    plsdev("xwin")
    plinit()

    [some code to create the arrays]

    plenv(xmin, xmax, ymin,ymax, 0, 0)

    plpoin(x,y, 20)
    plerry(n,x,y-errminus,y+errplus)

    pleop()
    plend()

	Help would be much appreciated. I'm really stuck on this one.

Thanks in advance,

Tiago Pereira
