The rise (or fall) of a SMA would be its steepness or its slope. Slope is usually expressed in terms of momentum.
The slope of a SMA can be expressed as Momentum(SMA), for example if you want to determine the slope (rise over run) of a 20-period SMA you can take the 1-period momentum of that SMA
rise over run = Momentum (SMA(20), 1)
If you have such numbers plotted on your chart, their absolute value is meaningless, as you will find larger values for a 60-min chart than for a 1-min chart. Therefore you would want to normalize the steepness by dividing it by the average bar size. In that case the steepness is displayed relative to the bar size, and you number would make sense.
But what do you need all those numbers for on your chart? That would be at best confusing.
