What steps will reproduce the problem? Please provide a link to a
demonstration page if at all possible, or attach code.

1. replace

actually, it's mathematically impossible to have a zero on a logscale axis - so
please remove both zeros!!!

I assume the playground uses v1.1 so this is still an issue. Replace the drawVisualization()
method with attached.

This seriously limits the quality of presentation of scientific data which often involves
small numbers. Scale should continue down below 1 as 0.1, 0.01, 0.001...

The attached example has fairly small y values (e.g. 10^-8; also common) and 0.00000001
is an inappropriate label so labels should automatically switch to exponent notation
or a property should be exposed to control label formatting.
