I had trouble with this as well. Log scale charts in splunk appear to be broken for non-positive powers of 10: Like the above example, when my data is from 0-1 the gridlines display for powers of 10 but the chart is still linear scale (0-0.01 is 1% of the scale, 0.01-0.1 is 9% of the scale, 0.1-1.0 is 90% of the scale). For a true log scale, 0.01 to 0.1 would have the same vertical scale as 0.1 to 1.0, 1.0-10.0, 10.0.100.0, 0.001 to 0.01, etc.) When I have data from 0.001-100, the data is charted log scale but the divisions are 0-10, 10-100, 100-1000). These are equally spaced but I would expect to see gridlines for 1.0, 0.1, 0.01. The result is that data from 1-100 is easy to visualize but data from 0.001-1.0 is compressed at the bottom of the chart My workaround is to chart log(value) on a linear scale, but this is not easy to consume for most folks.
