straight line graphs with no axes don't show up

[nazanin]

1. Create a graph with no axes with these values: (0,10), (1,10),(2,10),(3,10),..
Result: the graph doesn't show up since the max y value minus min y value becomes zero and scale which is span/(max - min) will become NaN.

Fixed it with this patch:

Use Dojo 1.2.2 or the trunk. Set min/max parameters on the axis.

[nazanin]

well that's the point. This happens when you graph with no axis''' in dojo/dojox/charting/plot2d/Base.js _calc function decides whether the graph has axis or not. So this problems doesn't occur when there are axis.

[elazutkin]

Yep, missed the point. Thank you for reopening.

Moving open tickets to the future.

bumping tickets that didn't make the 1.4 cut, but most likely to go in the next point release.
