package require BLT
# --------------------------------------------------------------------------
# Starting with Tcl 8.x, the BLT commands are stored in their own
# namespace called "blt". The idea is to prevent name clashes with
# Tcl commands and variables from other packages, such as a "table"
# command in two different packages.
#
# You can access the BLT commands in a couple of ways. You can prefix
# all the BLT commands with the namespace qualifier "blt::"
#
# blt::graph .g
# blt::table . .g -resize both
#
# or you can import all the command into the global namespace.
#
# namespace import blt::*
# graph .g
# table . .g -resize both

The barchart has several components: coordinate axes, data
elements, legend, crosshairs, grid, postscript, and markers.
They each control various aspects of the barchart. For example,
the postscript component lets you generate PostScript output.
Pressing the %%
set w $htext(widget)
button $w.print -text {Print} -command {
.bc postscript output bar.ps
}
$w append $w.print
%% button will create a file "bar.ps"
}

Hit the %%
set w $htext(widget)

$w append $w.quit
%% button when you've seen enough.%%
