This applet reads in a formatted data file and displays the results in a nice pie chart; useful for survey results and such. This applet is not used to gather or store any voting results, it assumes that there are other mechanisms or scripts in place to do that; it is for display purposes only.
The applet may be downloaded for free by clicking on the TAR-file link below (read the FAQ if you're not sure what to do with a TAR file). The FAQ also has step by step instructions on how to embed an applet into your own webpage.
Once unTARed, you should find the following classes (plus a '.jar' file if you want to use the archive= attribute in the <applet> tag):
Below are descriptions of all the parameters you may use to customize the applets to your webpages. Be sure to enclose any parameters that contain white space in double-quotation marks. Most parameters have default values in case you do not specify your own values, but the first two parameters (AUTHOR and COPYRIGHT) are necessary. If you are not sure how to incorporate an applet into a webpage (with its parameter names and values), looks at the source of this webpage and the applet embedded for an example, or read the FAQ page.
AUTHOR: This parameter must appear exactly as follows:
<param name=AUTHOR value="Eric Harshbarger, http://www.ericharshbarger.org">
COPYRIGHT: This parameter must appear exactly as follows:
<param name=COPYRIGHT value="PieChart applet, Copyright 1998, Eric Harshbarger">
BGCOLOR: This parameter indicates the background color of the applet. Consult the FAQ page if you are unsure what format to use for the parameter's value.
FGCOLOR: This parameter indicates the foreground color of the applet. Consult the FAQ page if you are unsure what format to use for the parameter's value.
FONTNAME: This value indicates the fontface used by the applet. Java1.0.2 has the following values from which to choose (must be spelled exactly): TimesRoman, Dialog, Courier, Helvetica, DialogInput, Symbol.
FONTSIZE: This value indicates the size of the font used by the applet.
FONTSTYLE: This value indicates the style of the font used by the applet. The value should be one of the following: plain, bold, italic, bolditalic.
DATA.FILE: This parameter points to a plain text file that indicates the names, 'vote count', and color of each entry for the pie chart illustration. Each line of the file should have the following information separated by the DELIMITER character (which defaults to a '|' symbol):
Entry Name/Title | vote count | color
Excellent | 12 | 255,255,0
Good | 6 | 255,0,0
Fair | 7 | 0,255,0
Poor | 3 | 0,255,255
DELIMITER: This is the character separator used in the DATA.FILE to separate the pieces of data. The default is the pipe symbol, '|'.
