				TESTHIST
				========

TestHist.exw is a program which demonstrates the drawing of a pie-chart and of 
a histogram for programs using EuWinGUI. The routines that do the job are in 
histo.ew, and the other include files in this folder.

The demo TestHist.exw shows how to call the routines PieChart() and Histogram()
and a model of the format that the data supplied to them should have, and has 
some other useful comments in it.

Calls to these routines may fail if you use extreme or strange dimensions for
the Picture control or the bitmap which is used for the drawing. Make them big 
enough to accommodate the pie-chart or histogram plus accompanying legend.

When you have tried the demo, look for the lines in the TestHist.exw which I 
have marked as "-- experimenting". These are experimental lines which I used 
during testing, and have now commented-out. Activate one or more of them and 
run the demo again to see the program run with different window size and "view"
size. Try some re-sizing of your own.

Andrea Cini's complete EuWinGUI package can be obtained as a download at the 
RDS website (www.RapidEuphoria.com).
