hello visad users,

i have two functions:
a) bucket       -> standard deviation
b) index                -> (bucket, deviation)          // where i mean by
deviation: observed value - average

and i want the values of function a) to be plotted as a thick line over and
under the corresponding bucket's 0-value
and the sample points of function b) just as points in the same display. of
course i want both to use the same scale on the y-axis. so that one can
clearly see when the deviation of a sample point is bigger than the standard

it seems that i can't use the same RealTypes for mappings to ShapeScale and
YAxis, because that way the shapes of function a) are drawn at the
corresponding y-value instead of 0. if i use different RealTypes instead
there seems to be no way to scale the shapes of function a to match the
scale of function b) (i mean if if standard deviation is 0.5 and the
observed deviation is also 0.5 the point of function b) should be exactly on
top of the shape).

can somebody help me?
