Implemented part of WB-377: Matrix Charting Updates: Matrix chart 'auto scales' to fit window unless the chart is manipulated by the user (panned, zoomed, or cell size changed).  Pressing the Reset button returns to 'auto scale'.
Correction for reopened WB-375: Identification symbol size on dialog was mistakenly set to the symbol color which caused the wrong size symbol.
Removed print statement
Resolve reopened WB-406 Chart Y Axis... Number of ticks was fixed and it causes some problems with axis scaling.  Number of ticks is now variable and corrects the problem with two '1' values in a particular scene.
For non-modal dialogs, when the dialog is closed, save its position but not size.  Since the dialog is not destroyed, only hidden, there is no need to save the size.  And, if the dialog's content changes, the old size my be inappropriate.
