Nice graph Jim :-)

The labelling of your x y axis would be better (mathematically correct) by
using / instead of ( )

Current / mA instead of Current (mA)

Oddjob ;-)


I've never bought this theory - that the axis of a graph is the other
side of an equation. As far as I am concerned the graph axis is the
current in milliamps - not one-over-milliamps (or current per milliamp
as you have it, which is dimensionless).

So it is Current (mA) - a good label
Not Current / mA - an incorrect representation of what is on the
graph.

But the axis is the description of the quantity on the graph, so that:

Current / mA = 300 therefore

Current = 300 mA this is correct :-)


Current (mA) = 300 transposes as:

Current = 300 per mA this is not correct

The above must be correct :-))


No what I want from an axis label is a description of the units I must
attach to the value I read on the graph. If the value is 300, and the
unit is mA of current, then current (mA) is the label I want to read.
It is not a formula - it is a description.
