I have a graph where the Y axis is logarithmic, from 10^1 down to 10^-4. Right now the labels on the axis read from 10 to 0.0001 (though really it's 0.00009999 repeating, not good), and I'd like it to read as 10 to the power of x. How can I format my labels to do that? Or at the very least, fix the last label so it doesn't look like the screenshot...
