Hi,

I am having a problem with version 0.9.10 of Graphite when applying a logarithmic scale (base 10) on the y axis and specifying a minimum value of 1 to the axis.

The series data has a value of about 42k and it renders correctly without the scale or the minimum value.

If I apply a minimum value of zero to the y-axis it renders correctly, but if I specify a minimum value of 1 Graphite chooses a maximum value of 40k so the series it not visible. I'm not too bothered about this but thought it was worth mentioning.

If I apply a logarithmic scale (base 10) on the y axis without a minimum set the series renders  correctly but if I specify a minimum value of 1 the series is rendered below the 10k line which is incorrect.

Any help would be greatly appreciated,
Campbell
