Have you tried formatting the source data to show all 6 decimal places?
Heres how...
Highlight the source cells
Right click and select format cells
on the number tab;
Category: Number
Decimal places: 6
Then click Ok

One other thought is that the chart may be to narrow to display all the
digits..if so,
try making the chart wider or making the text size smaller

I have a trend chart, its data table showing 6 digits for 12 periods. But it
won't show all digits on the chart, what's the best way to show all digits in
the data table?
