Problem locating

This problem exist here:

echarts/src/scale/Log.ts

Lines 74 to 76 in 5cf53e2

	powVal = (val === extent[0] && this._fixMin)
	? fixRoundingError(powVal, originalExtent[0])
	: powVal;

When Echarts tries to obtain the extent of data and set ticks, it's trying to use the precision of originalExtent to fix powVal. This behavior is to fix the problem of #4158, where precision issue is caused by logarithm and exponentiation. However here powVal can be user-set min/max, which is 0.01 here and originalExtent is the real extent of data, which is 44 here. When using the precision of 44 to fix 0.01, tick value becomes 0 and it has nowhere to go on log axis. That's the reason why there's a big 0 up there.

Plan to fix

The way to fix #4158 is not fixing it completely (a user-set max of 2000000000000 still displays wrongly) and it also causes #16992. My plan is to change the way to fix #4158 and can fix #16992 in the same time.
