# straight line graphs with no axes don't show up

### Description

- 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:

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.

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

**Note:**See TracTickets for help on using tickets.

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