<p>Odometer graphs uses the metaphor of an old fashioned speedometer for cars. It is
|
|||
|
|
normally used to give a quick overview of one specific parameter. Experience have shown
|
|||
|
|
that this type of metaphor is easily and quickly understood by most people. By adding
|
|||
|
|
color indications to the odometer it is very quick to see whether or not a specific
|
|||
|
|
value is within a allowed range or outside. </p>

<p>Odometers produced with this package have a wide range of functionality and as you
|
|||
|
|
would expect almost every bit of visual layout is in one way or the other
|
|||
|
|
customisable. For simple use there are suitable default values for most parameters
|
|||
|
|
which will make creation of simple Odometer just a matter of a few lines of code. </p>
