Back in 2017, txnelson posted a nice snippet of code to do this:

```
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA\Big Class.jmp" );
Dis = dt << Distribution(
Continuous Distribution( Column( :height ), Vertical( 0 ), Density Axis( 1 ) )
);
Report( Dis )[Frame Box( 2 )] << Add Graphics Script(
mu = 63;
sigma = 3.2;
Pen Color( "Red" );
Y Function( Normal Density( (x - mu) / sigma ) / (40 / 12), x );
mu = 51.5;
sigma = .87;
Pen Color( "Blue" );
Y Function( Normal Density( (x - mu) / sigma ) / (40 / 2), x );
);
```

To scale the curve properly, you need the total number of data points divided by the data points for the maximum bar in the histogram distribution (here shown as 40/12 and 40/2) . Is there a way to calculate these? I can get the former, but not the latter.

Thanks for any help,

John
