Hi Joe,

Graphs with gaps are not implemented in ROOT and we have no plans
to implement this feature in the short term. This has several
implications (lin/log scales, picking, superimposed fitted functions, etc)

The only possibility that I see is to call the basic primitives
or use an index (what you already do if I understand).
For the axis values, you have to draw the individual axis labels one by
one.
