viewWindow ignored in log-log plots

[rmhubley]

The viewWindow min/max range does not appear to control the extremes shown on a graph when scaleType is set to 'log'. For example the following doesn't set the scale explicitly:

var opt_DF0000058 = {
title: 'data1',
vAxis: {
scaleType: 'log',
viewWindowMode: 'explicit',
viewWindow: { min: 0, max: 10000000} },
hAxis: {
scaleType: 'log',
viewWindowMode: 'explicit',
viewWindow: { min: 0, max: 100000} },
width: 200, height: 200
};
