Changing ScrollPager.ColorBandTool StartValue and EndValue doesn't affect the main chart.

It could be interesting to add some method to both set the ColorBandTool values and the Parent Chart Axis Range with onw unique call.

At the moment, if you do this:

  ScrollPager.ColorBandTool.StartValue:=500;
  ScrollPager.ColorBandTool.EndValue:=600;

The main chart doesn't set its bottom axis min and max; you still have to do it manually:

  Chart1.Axes.Bottom.SetMinMax(500, 600);

Implemented.

ColorBand tool has now a new event "OnChanged" that is called whenever the color band Start or End values are modified.

This event is now used internally by ScrollPager tool to refresh the parent chart.
