Graph being rendered with very low values, this can cause the Y axis to be rendered with different points for the same value of "0", causing multiple "0" on the Y Scale.
This appears to be being caused by the relatively low granularity of the Y-axis of the graph and the high granularity of the data being plotted (.e.g. 0.000032, 0.000064).
This sort of graph rendering will only really occur if there is very low values needed to be plotted, my problem is that I need very large values and very small values on the same graph as the data can change.
It is possible to change the Y axis scale to to allow for floating points when the values become very small?
This sounds like a bug, would it be possible for you to post a screenshot? And what version of Splunk are you using?
In the meantime, there are a couple of potential work-arounds. If your data is all very small numbers, you could set an explicit minimum/maximum/interval for the y-axis. You could also try setting the y-axis to log scale.
