Dear All,

I've figured out that I can use LinearLocator and set ylim manually to 
fix the number of ticks. But I still don't know to set the display 
precision of the scientific notation. Currently I can only work around 
this by choosing proper limits and number of ticks manually. Is there 
anyway to fore the display precision (i.e, "3.33x10^-6" instead of 
"3.33333333333 x10^-6") ?

Thanks very much!

Sincerely yours
Xing

The example here:

will probably help.
