<b>1. What is EasyCharts?</b>
</font>
<p>
EasyCharts is a Java<sup>tm</sup> based charting library that enables you to
add charts to your java applications and web pages. The library contains AWT
based chart components, applets, and a chart servlet.
<p><br>
<a name="chart_types"></a>
<p><font color=darkred>
<b>2. What chart types do EasyCharts support?</b>
</font>
<p>
EasyCharts supports horizontal and vertical bar charts, stacked bar charts,
pie charts, line charts, stacked line charts (area charts), and overlay
charts. All charts can be displayed in 2D or 3D.
<p><br>
<a name="install"></a>
<p><font color=darkred>
<b>3. How do I install EasyCharts?</b>
</font>
<p>
Unzip the EasyCharts distribution file to your disk. You should now be
able to test the chart demos opening the demo files with your web browser.
<p>
For applet use, copy the chart.jar file to the web directory where your file
containing the applet will be, then set the applet tag to the following:
<p>
<applet code=com.objectplanet.chart.BarChartApplet<BR>
archive=chart.jar width=300 height=200><BR>
</applet>
<p>
If you need the applets to run on older browsers (older than Internet
Explorer 4.0 and Netscape 4.06) create a directory called
com/objectplanet/chart102 in the directory where the applet file will be.
Then copy the *.class files from the same directory in the EasyCharts
distribution to this directory, and set the applet tag to the following:
<p>
<applet code=com.objectplanet.chart102.BarChartApplet<BR>
codebase=./ width=300 height=200><BR>
</applet>
<p>For java applications, import the chart.jar file into your development
environment, or add the file to your CLASSPATH environment variable.
<p><br>
<a name="license"></a>
<p><font color=darkred size=2>
<b>4. What is the licensing polisy for EasyCharts?</b>
</font>
<p>
You need one license for each developer using EasyCharts. If you have 2 people
developing your application and one tester, you need three licenses. You need a
source license for each person having access to the source code.
<p>
If you are developing an application for a client, you need to purchase a
license on behalf of the client.

<p><br>
<a name="royaltee"></a>
<p><font color=darkred>
<b>5. Can EasyCharts be distributed without royaltee fees?</b>
</font>
<p>
Yes! The purchase of a developer kit, includes a license to distribute the
chart binaries without royaltee fees as long as they are distributed as an
integral part of your end user java or web application installed on a web
server or client computer and executed solely on the client machine.
<p>
You must purchase valid development licenses for each developer
working with EasyCharts.
<p>
If any EasyCharts software is executed on a server, you need to purchase
a server installation license for each installation in addition to a developers
kit that includes the software.
<p><br>
<a name="which_license"></a>
<p><font color=darkred>
<b>6. Which EasyCharts license(s) do I need?</b>
</font>
<p>
If you want to use EasyCharts as applets or in java applications without
modifications the EasyCharts binary developers kit should cover your need.
<p>
If you want to use EasyCharts in java applications and modify the charts
in any way you need to purchase the EasyCharts source developers kit.
<p>
If you want to execute any EasyCharts software on a server such as running it
as a servlet generating images of the charts, you need to purchase one
EasyCharts server installation license per server in addition to any of the
above two licenses.
<p><br>
<a name="pricing"></a>
<p><font color=darkred>

<a name="difference_applets"></a>
<p><font color=darkred>
<b>13. What is the difference between EasyCharts and ObjectPlanet's Bar/Line/PieChartApplet</b>
</font>
<p>
EasyCharts is a complete java chart library that includes components with
a full java API to be used in java applications, applets to be used
in web pages, and a servlet to generate charts as jpeg images.
<p>
The applets found at
<a href="http://objectplanet.com/comp/BarChartApplet">
http://objectplanet.com/comp/BarChartApplet</a>,
<a href="http://objectplanet.com/comp/PieChartApplet">
http://objectplanet.com/comp/PieChartApplet</a>, and
<a href="http://objectplanet.com/comp/LineChartApplet">
http://objectplanet.com/comp/LineChartApplet</a>
are optimised for applet use and has a smaller footprint and better
compatibility than the applets in EasyCharts.
<p>
However, these standalone applets do not support all features found
in EasyCharts.
<p><br>

<a name="examples"></a>
<p><font color=darkred>
<b>16. How do I run examples from the examples directory?</b>
</font>
<p>
There is a file called runexample.bat in the examples directory.
To run an example type <i>runexample example_name.</i><br>

</font>
<p>

<p><br>
<a name="applets"></a>
<p><font color=darkred>

applet tag like the following:
<p>
<applet code=com.objectplanet.chart.BarChartApplet<BR>
archive=chart.jar width=300 height=200><BR>
</applet>
