Summary: Tick marks not rendered: Dataset with extremely small values

Initial Comment:
Tick marks not rendered or no. of tick marks are very few when the dataset contains extremely small values (1.10E-07, 1.55E-07, ...).

Using XYDataset to store the values.

Using the following workaround suggested by Dave Gilbert to overcome this.

TickUnitSource units = new StandardTickUnitSource();
axis.setStandardTickUnits(units);

In some cases, the range is extremely large and the data is squished between 2 tick marks 

For e.g.
If the dataset range is between 1.15E-8 to 1.96E-8, then the domain axis range is ( lowerBound:9.87E-9, upperBound:2.073E-8 ) which is fine. But if the values are between 1.15E-9 to 1.96E-9, then the domain axis range is large ( lowerBound:-3.5130000000000006E-9, upperBound:6.573E-9).

Using "setAutoRangeMinimumSize()" to overcome this.
