[PyX-user] outward pointing ticks on x2

[Arnd B. <arn...@we...>]

Hi,

I have a presumably very simple question,
but cannot see the solution:
How can one get get ticks pointing outward on the y2 axis?

The following does not work:
########################################
import pyx

xpaint = pyx.graph.axis.painter.regular(innerticklength=0,
           outerticklength=pyx.graph.axis.painter.ticklength.Long)
ypaint = pyx.graph.axis.painter.regular(innerticklength=0,
           outerticklength=pyx.graph.axis.painter.ticklength.Long)
y2paint = pyx.graph.axis.painter.regular(innerticklength=0,
           outerticklength=pyx.graph.axis.painter.ticklength.Long)

g = pyx.graph.graphxy(width=10,
      x=pyx.graph.axis.linear(min=0, max=5, painter=xpaint),
      y=pyx.graph.axis.linear(painter=ypaint),
      # Q: how to get ticks pointing outward here?
      #y2=pyx.graph.axis.linear(painter=y2paint)
                      )

g.plot(pyx.graph.data.function("y(x)=sin(x)"))
g.writeEPSfile("test_painter.eps")
########################################

Uncommenting the line
  #y2=pyx.graph.axis.linear(painter=y2paint)
gives
    raise RuntimeError("incomplete axis range%s" % errorname)
RuntimeError: incomplete axis range for axis y2

Can one somehow get a couple range for y2,
but specify a different painter?

Usually the plan to post a question leads to the answer,
but this time it did not work...;-)

Many thanks,

Arnd
