fix non visible 0% tick axis since the switch to swtchart 0.14

[mierin12]

Hello,

Issue : #4312 (comment)

Since switching to swtchart 0.14, the tick on chart axis for 0% does not appear anymore. As per the linked comment, it may be already fixed by swtchart but only available in the next release ? I am not sure.

I do not know why this works, but noticing than chart axis with the ThousandAmountFormat did not had this issue, I tried to use a similar approach. On my Windows it works. Maybe there is a simpler way to get it done ?

Maybe the naming could be improved for maintainability point of view ? PercentNumberFormat -> AxisTickPercentNumberFormat ?

Very interesting fix. I really do not understand why this works, but it works.

I understand that SWTChart ist about to publish a 1.0.0 that would fix it, see eclipse/swtchart#410. But I plan to publish a new version this weekend. And that is a big change in an upstream library to include on such a short notice. The last release is 2 years old! I'll merge it and we can remove it once we adapt 1.0.0 .

I'll also take up your suggestion for renaming.
