Not possible to update category axis completely using load() if number of new categories > number of categories used when generating the chart

**Version**: 0.4.11
**Browser**: Chrome Version 50.0.2661.94 (64-bit)

Let **N** be number of categories used when generating a chart with a category axis. Let **n** be the new number of categories you want to use when updating the chart with new data, using _load()_.

If **N >= n**, everything works correctly
If **N < n**, only the first **N** categories will be updated. The rest of the categories are not shown.

Here's a fiddle demonstrating the problem: https://jsfiddle.net/e50czn7r/2/
