Examples of org.jfree.chart.axis.CyclicNumberAxis

org.jfree.chart.axis.CyclicNumberAxis
This class extends NumberAxis and handles cycling. Traditional representation of data in the range x0..x1
```
 |-------------------------| x0                       x1 
```
Here, the range bounds are at the axis extremities. With cyclic axis, however, the time is split in "cycles", or "time frames", or the same duration : the period. A cycle axis cannot by definition handle a larger interval than the period :
```
x1 - x0 >= period
```
. Thus, at most a full period can be represented with such an axis. The cycle bound is the number between x0 and x1 which marks the beginning of new time frame:
```
 |---------------------|----------------------------| x0                   cb                           x1 <---previous cycle---><-------current cycle--------> 
```
It is actually a multiple of the period, plus optionally a start offset:
```
cb = n * period + offset
```
Thus, by definition, two consecutive cycle bounds period apart, which is precisely why it is called a period. The visual representation of a cyclic axis is like that:
```
 |----------------------------|---------------------| cb                         x1|x0                  cb <-------current cycle--------><---previous cycle---> 
```
The cycle bound is at the axis ends, then current cycle is shown, then the last cycle. When using dynamic data, the visual effect is the current cycle erases the last cycle as x grows. Then, the next cycle bound is reached, and the process starts over, erasing the previous cycle. A Cyclic item renderer is provided to do exactly this.
