A GraphiC Picture Gallery
||This example shows an advertisement for GraphiC
made entirely using GraphiC. The plot illustrates GraphiC 's
ability to insert one plot within another, and its sophisticated
treatment of text.
||GraphiC can create your plot legends
||This simple bar chart illustrates stacked bars and a legend that
can overlay the plot area.
||Polar contour plots and curves can be combined to
illustrate several quantities at once.
||Three-dimensional line plots enable you to visualize complicated 3-D
||Pollution data (as measured from an airplane) are easy to display
using a "plume" plot.
||With GraphiC, you can combine 3-D surface and stacked contour
||Note how curve labels can be projected into 3-D
||GraphiC uses a palette of 248 colors and 16 geometric patterns to
The next series of plots illustrates how GraphiC was used to
help understand air traffic flow.
||This unique plot illustrates the air traffic performance
throughout a day at the Knoxville airport. It also illustrates
that GraphiC is a vector graphics package. GraphiC
plots can be zoomed to display small details.
||A snowstorm in Boston causes delays to increase as the day goes
on. Since most delays are small (less than 1 hour), the radial scale
is nonlinear. Note also the ability to draw character strings on an
Note especially GraphiC's
ability to create complicated contours with thousands of sides, internal
holes, and multiple disconnected regions. Also, GraphiC can print
these contours to output devices such as PostScript printers, which have a
limit of about 400 sides per panel.
These three plots illustrate different ways to plot the same
||This plot is called a "patch" plot. It assigns the average
of the corners of each grid cell to the center of the grid cell.
Patch plots are best for illustrating data that may be discontinuous
(such as in this case).
||Discontinuous data must be smoothed to create a contour plot.
The plot is prettier, but perhaps less informative.
||Finally, the same data can be plotted as a 3-D contour plot.
In this case, we used GraphiC's 16 levels of gray to make a
black and white plot. The ability to illustrate your point without using
color is important if your journal does not allow color pictures, or if it
charges extra for them.
