# tkextlib/tcllib/plotchart.rb
# by Hidetoshi NAGAI (nagai@ai.kyutech.ac.jp)
#
# * Part of tcllib extension
# * Simple plotting and charting package
#
# (The following is the original description of the library.)
#
# Plotchart is a Tcl-only package that focuses on the easy creation of
# xy-plots, barcharts and other common types of graphical presentations.
# The emphasis is on ease of use, rather than flexibility. The procedures
# that create a plot use the entire canvas window, making the layout of the
# plot completely automatic.
#
# This results in the creation of an xy-plot in, say, ten lines of code:
# --------------------------------------------------------------------
# package require Plotchart
#
# canvas .c -background white -width 400 -height 200
# pack .c -fill both
#
# #
# # Create the plot with its x- and y-axes
# #
# set s [::Plotchart::createXYPlot .c {0.0 100.0 10.0} {0.0 100.0 20.0}]
#
# foreach {x y} {0.0 32.0 10.0 50.0 25.0 60.0 78.0 11.0 } {
# $s plot series1 $x $y
# }
#
# $s title "Data series"
# --------------------------------------------------------------------
#
# A drawback of the package might be that it does not do any data management.
# So if the canvas that holds the plot is to be resized, the whole plot must
# be redrawn. The advantage, though, is that it offers a number of plot and
# chart types:
#
# * XY-plots like the one shown above with any number of data series.
# * Stripcharts, a kind of XY-plots where the horizontal axis is adjusted
# automatically. The result is a kind of sliding window on the data
# series.
# * Polar plots, where the coordinates are polar instead of cartesian.
# * Isometric plots, where the scale of the coordinates in the two
# directions is always the same, i.e. a circle in world coordinates
# appears as a circle on the screen.
# You can zoom in and out, as well as pan with these plots (Note: this
# works best if no axes are drawn, the zooming and panning routines do
# not distinguish the axes), using the mouse buttons with the control
# key and the arrow keys with the control key.
# * Piecharts, with automatic scaling to indicate the proportions.
# * Barcharts, with either vertical or horizontal bars, stacked bars or
# bars side by side.
# * Timecharts, where bars indicate a time period and milestones or other
# important moments in time are represented by triangles.
# * 3D plots (both for displaying surfaces and 3D bars)
