The lowest three vertical axis labels have the same value of zero

SUMMARY
Net Worth Graph with automatically calculated range has multiple zero labels if
in some point in time the net worth was equal to zero and logarithmic vertical
axis is used.

STEPS TO REPRODUCE
1. Prepare an account that in it's history has months of zero and positive
balance.
2. Go to Reports -> Net Worth Graph and click the 'Configure' button.
3. In the Report -> Chart tab enable 'Logarithmic vertical axis' checkbox.
4. In the Report -> Range tab select Range: Automatic and Labels precision
equal to 2. Select a Date range wide enough to let zero and positive account
balance be shown.
5. In the Filters - > Account tab select the previously prepared account.
6. Click the Apply button.

OBSERVED RESULT
The lowest three vertical axis labels have the same value of zero.

EXPECTED RESULT
The chart should be cropped to the precision limit which in this case would be
10^(-precision) = 10^(-2) = 0.01. This should be the value of the lowest axis
label.
