How do I change time axis labels?

[barney99]

I have a few data plots that show some parameter on the y-axis versus time on the x-axis.  The data spans several months (sometimes years).  Currently my x-axis shows date labels for the left and right side of the plot and one value inbetween (happens to be 12-31-09).  How can I set the axis format to show a label for each month or each major grid interval?  Anything would be an improvement over just one date label.

Thanks

Try right-clicking directly on the axis label and select your desired style.  You must click right on the label text or you will not get the correct pop-up menu.
