<para>
Here you can see the logical location of the device. If you have more
than one game controller, you can also select which one to configure.
</para>
<para>If no game controller is automatically found on your computer
and you know that there is one attached, you can enter the correct device file here.

<varlistentry><term><guilabel>Position</guilabel></term>
<listitem>
<para>
The plotted location of the X and Y axes of the game controller's joystick. Enable <guibutton>Show trace</guibutton>
to plot the path of the joystick from one point to another.
</para>
<tip><para>
If the joystick cannot reach every point on this graph, or if it does not center correctly, you need to calibrate your device.

<varlistentry><term><guilabel>Buttons</guilabel></term>
<listitem>
<para>
A place to see the pressed state of buttons on your game controller and if the buttons
are mapped correctly. When a button is pressed, <guilabel>PRESSED</guilabel> will appear
next to the logical number (as the computer sees it) of the button which was
pressed.

<varlistentry><term><guilabel>Axes</guilabel></term>
<listitem>
<para>
This displays the numerical values of the axis positions. 0 is centered and the
maximum and minimum values depend on the game controller and the particular axis.

<para>
Each axis will have to be moved to the minimum position, then the center, and finally the
maximum position. A meter in the bottom left corner of the dialog will help
determine which way increases and which way decreases the values.
