max labels displayed

I have a chart in excel 2007 with 106 labels. I have selected the interval unit to be 1, but the chart only displays every other label. After experimenting, it appears that if I reduce the number of labels to 100 then every label will be displayed, but as soon as I go over 100 it reverts to every other. This is very annoying - does anyone have an answer please? Thanks.

ok, it seems that although I had previously tried reducing the font size (which didn't work) I have to also use a different font style eg the chart will display all labels with arial 8, but not with calibri 8 !

I am having the same problem. I've got 113 labels, but it will only display every other one. Reducing this to 100 displays every one. Changing the font, size or graph area doesn't seem to help. Must be a bug in excel.
