e.g.
x-axis data -> 5/1, 5/2, 5/3, 5/4
x-axis data -> 6/6, 6/8
y-axis data -> 100, 200, 300 (belongs to MAY)
y-axis data -> 400, 500, 600 (belongs to JUNE)
on x-axis i ONLY want to show MAY, JUNE NOT 5/1, 5/2, 5/3, 5/4, 6/6, 6/8
so in this e.g im grouping months, im not sure if im using right term or not...but this is what im looking for..
sorrry i couldn't draw chart visually
