Error when series contains only zeroes

[haavikko]

The error occurs at least with graph type "column".

Error can be reproduced by modifying testcase test_chart2d.html (see attached file). The relevant part is the following:

chart20.addSeries("Series A", [0,0,0,0,0], {stroke: {color: "red"}, fill: "lightpink"}); chart20.addSeries("Series B", [0,0,0,0,0], {stroke: {color: "blue"}, fill: "lightblue"});

On IE7, I get error: 'major' is null or not an object

On FF3, I get error: ticks is null
