Improved Axis/Grid Engine
The new Axis/Grid Engine is the biggest update to HanengCharts 3.0. Where HanengCharts 2.x
used a fixed number of axis marks for each chart, HanengCharts 3.0 now dynamicaly tests
and selects the number of axis marks that best fits the chart. Also the selection of the
maximum and minimum values used for the axis is now more dynamic and smarter resulting
in charts that looks better and are easier to read.
Example 1: Percentages
In the first example we see that when charting percentages HanengCharts 2.x shows an y-axis
with a maximum value of 120, while the HanengCharts 3.0 maximum is 100 which looks much better
when we are dealing with percentages.

Example 2: Better maximum values
In the next example we can see how HanengCharts 3.0 chooses a higher maximum value
than HanengCharts 2.x so that the resulting intervals between values on the y-axis looks better.
You can also see how HanengCharts 3.0 uses more axis marks to draw a better axis.
