Logarithmic Y-axis doesn't work with 0 value points

[josephruscio]

There are several issues with Highcharts 2.2.0 when attempting to use a logarithmic Y-axis with a datetime X-axis. If the Y-axis extremes are not explicitly set to something like [0.1, 10000.0], it fails to render at all. Even if you set that and it renders the series initially, subsequent calls to series.setData with an updated series does not render the new points, and the console has lots of errors like this:

JS Fiddle example using one of your the Time Series demo's from the Highcharts website.

[TorsteinHonsi]

The error is in the data - the data set in this example contains 0 values, which don't apply to a log axis. When you omit setting yAxis.min, Highcharts correctly throws this error in the console. However, when you set min to 0.1, it slips the error checker and tries to plot the 0 values. So the bug fix is to extend the error check to look for zero or subzero dataMin as well as axis min.

PS: The connection to datetime x axis is a coincident, it doesn't really have anything to do with the real issue.
