Bounded Logarithm Scale for Particle Count Data

When graphing or plotting count data from particle sensors, there is always the problem of handling zero values if a logarithmic scale is desired. The one plotting (or programming) may skip the offending values, leaving all values equal to 1 across the bottom of the graph. Or, a constant may be adde...

description When graphing or plotting count data from particle sensors, there is always the problem of handling zero values if a logarithmic scale is desired. The one plotting (or programming) may skip the offending values, leaving all values equal to 1 across the bottom of the graph. Or, a constant may be added to all the counts to provide an offset from zero. We offer an approach with the advantage of changing only one label on the graph, yet allowing all values between 0 and 1 to be plotted automatically. The change is simple to program and can be equally easily used in manual plotting.
