It sounds like you are using an XY chart.
For XY trend charts, I often run into the issue you are talking about
frequently. I use a few formatting tricks:
For my X Axis number format I double click the X axis to get Format Axis
window. I select number tab and enter my date format. For monthly data
spanning years, I use "mmm'yy" which will show up as Mar'06 on the chart X
axis.
For my interval, I use 32 days to make sure that I get my months to
increment.
I have several trend chart examples at
