Mutliple major units in excel axis

Hello.
I am plotting a x-y scatter chart..
Is it possible to have mutilple major units for the axis.

For eg
From 1 to 100 I have many points so I want the major unit to be 5 in this case, but then i have some values in 250 to 700 range.
So from 100 to 700 i want the major unit to be 100.
Is it possible.
