Since the log of 0 is -Infinity, we can't show 0 on a pure log scale chart
unless it is infinitely long. However, you can get what you want, if I
understand you correctly, by using a different log scale which shows values
close to zero in a linear scale.
vAxis: {scaleType: 'mirrorLog'}
which looks like this:

This mode also shows the log of negative values as the negative of the log
of the absolute value.
