Features
| Features |
| Small footprint |
The
applet comes with a footstamp of about 27 KB.
This is of importance when users have small download
bandwidth.
|
| Simple configuration |
The
configuration of the applet is very simple. Only very
few of the parameters are needed to show a useful
graphic. |
| Specialized |
The
specialization of this applet to show only bar chart
allows for the simple configuration and small footprint. |
| Compatibility |
The
applet is entirely written in Java 1.1. This allows
it to be shown also by the most founded versions of
browsers like Netscape Navigator or Microsoft InternetExplorer. |
| Automatic range calculation |
The
applet automatically calculates a useful number of
ticks on the x-axis |
| Automatic scale calculation |
The
applet automatically calculates a useful minimum and
maximum of the x-axis |
| Automatic border scaling |
The
border for the labels is adjusted automatically to
the length of the labels you provide. |
| Individual color for bars |
Each
bar has its individual color, either provided by applet
parameters or randomly assigned by the program |
| Data labels |
You can switch data labels
on and off. This means, that the value of a bar is
printed inside or besides the bar in the graphic,
dependent on the bar size. The color of the labels
can separately set for labels inside the bars and
outside the bars. |
| Background colors |
You can assign a color to the
applet background and to the chart background. By
default, both are set to white. |
