Vertical max calculations for stacked-plot axes not consistent with how values are populated

[mcchriste]

In the dojox.charting.plot2d.common.js file, in the collectStackedStats function, the calculation uses only the value of the series?.data[i] to compute the max value instead of possibly getting the value of the series?.data[i].y value, like the stacked plots do. This leads to improper scaling on the vertical axes so that data is badly cut off when series are specified as [(y:1},{y:5}]

Current:

var v = series[0].data[i];
if(isNaN(v)){ v = 0; }

and

var t = series[j].data[i];
if(isNaN(t)){ t = 0; }

Both need to be changed by appending another line here like so:

var value = series[0].data[i];
var v = typeof value == "number" ? value : value.y;
if(isNaN(v)){ v = 0; }

Bumping from non-existant 1.5.1 to 1.6.
