Statistical tests view throws exception before opening

[abeham]

To reproduce:

• Open GA-TSP sample
• Change MaximumGenerations to 10, change PopulationSize to 10
• Make 6 runs
• Change PopulationSize to 20
• Make 6 runs
• Open statistical tests view on RunCollection

In my case I got this exception and the view didn't open:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

r12173 fixed bug in HistogramControl when the interval is zero

[abeham]

The histogram page now is just empty. The legend is displayed, but no chart is actually drawn. Please put a message on the view that displays the reason for the missing chart...

Take a look at the bubble chart for example. A similar message is displayed there when you first open it.

r12458 show label when no data is displayed and don't show the legend

[abeham]

Tested the functionality, it works. I think we may run into a merge conflict with ticket #2270. They should be released together.

r12725: merged r12173, r12458, r12077, r12599, r12613, r12112, r12116, r12117, r12131, r12631, r12672, r12684, r12690, r12692 into stable
