chart line style problem

[Guest]

I am making a scatter chart (with lines) in Excel 2007 under
Vista. I can select a line style, for example, long dashes.
However, if I try to change the axis (change from "automatic" to
"fixed" on the horizontal axis), the line on the chart immediately
becomes solid again. The legend still shows the proper dashing.
I can get the dashing partly back by making the line thinner,
but only where the variation is fastest - regions where
the derivative is near zero are still solid even for thin lines.

I'll appreciate any help!

I was not able to reproduce this.
Can you send me a sample file (private email, not to newsgroup)
