I have numerous graphs wherein the X Axis represents the DATE.

When I scroll my mouse along the graph line (searching for data points), I
often see the accompanying data as...

Series 1 Point "39409"
Value 209
instead of:

Series 1 Point "22-Nov"
Value 209

HOW CAN I AVOID THE REFERENCE ON THE DATA LINE FROM REFLECTING THE
SERIAL NUMBER INSTEAD OF THE DATE ITSELF??? (such as "22-Nov".)

Thanks,
