Qt version 4.6.2

Code:

from cranvas-ex.R

library(cranvas) data(tennis) str(tennis)

the first step is always to create the data object

qtennis = qdata(tennis, color = serve.speed, size = aces)

then create plots

qhist(serve.speed, data = qtennis)

Problem:

data does not display unless a bar region is selected (highlighted).

is is possible for you to upgrade to Qt 4.7.4? Tengfei and I are using Ubuntu 11.10.
