1. Right click on the chart, select Chart Type from the pop up menu, and
choose either Line Chart or XY Scatter Chart, depending on whether you
want a categorical or numerical axis. For more info:

Scatter Chart or Line Chart?

2. To do this you need to massage your data, and to skip a range on your
axis, you need to construct a dummy axis:

Thanks for your answer.
1. But is it possible for me to change its scaling style
(eg change X-axis or y-axis into fixed scale or
non-fixed scale?

2. Also is this previous question solvable:
===========
how can I omit some values in X-axis or y-axis?
Eg: I just wish to show values of "1-10", "25-30" in y-
axis, others (ie "11-24") should be hidden.
