You can now customize the appearance of markers in a 2-D plot exploration as well as fix one of the coordinates of a marker.
To customize the appearance of a marker, use the plot options color, symbol, and symbolsize in the markers options sequence. By default, all markers have the same customizations, but you can override the default customization by setting customizations for individual markers. For example, in the following Explore command call, all of the markers have their appearance set to color=blue, symbol=solidcircle, and symbolsize=25, except for the first and th markers (where the color=red option overrides the color=blue option).
To fix one of the coordinates of a marker, specify a fixed numeric value for that coordinate. In the following example, all of the markers have fixed horizontal positions (specified by the list xini). Their vertical positions, however, are set to variable parameters. In the exploration, you can change the vertical position of any of the markers but you cannot change their horizontal positions.
