How to Normalize a Histogram Y axis to 0-100% instead of cumulative frequency.

Hi Guys,

I need to plot a histogram of decisions taken by logic of a vehicle ECM parameter

Currently this plots according to frequency using

hist(parameter name)

Instead of frequency I need it to normalise the Y axis so that it plots between 0 and 100%

I have looked at several examples and have not been able to make them work.

Using minitab I have been able to do this so I know that the data can be presented like this.

Any help would be greatly appreciated.

I would also like to add a fit line to the Histogram if anyone can help with that.
