Visible yaxis must be sorted first in order for them to show

Explanation

Ordered is when the series and config with yaxis's show property set to true are FIRST in arrays of config AND series, while when they're set to false, they're AFTER all element with show as true.
This result in correct behaviour, 3 axis are shown.

When it's not ordered, there is some yaxis's show property set to false before another one with true, which result to that axis never displayed. If a series with yaxis show is set to false as the first axis, then no axis will be displayed at all.

I noticed that the y-axis is present, but it is outside the visible area.
Hence, this is related to #98 and will be fixed when the calculation of y-axis positions is corrected.
