There is an unhandled exception in the box plot view. See the stacktrace below.

I had a similar error in the bubble chart today, maybe it's related to the error in the box plot.

Reproduce:

1. Create new Random Forest Classification
2. Load small dataset (e.g. wine)
3. Use the experiment creation dialog to create a small experiment (tick M, R, and NumberOfTrees) - it should run long enough to test the effect
4. Execute the experiment and while it is calculating open a bubble chart.
5. In the bubble chart select y and x axis (I used accuracy for y and R for x).
6. Then click and drag the x-jitter slider
7. When the experiment is still calculating an exception dialog should appear

Very strange code in BubbleChartView:

      } else {
        axis.Minimum = axis.Minimum;
        axis.Maximum = axis.Maximum;
        axis.MajorGrid.Interval = axis.MajorGrid.Interval;
        axis.MajorTickMark.Interval = axis.MajorTickMark.Interval;
        axis.LabelStyle.Interval = axis.LabelStyle.Interval;
      }

r8832: suggested fix for strange method SetAutomaticUpdateOfAxis(). Exception is gone but don't know if originally intended functionality is still intact.

r8835: Refactored jittering in BubbleChartView to calculate axis range before the data points are modified and removed 'strange' method.

Reviewed r8835.
