Don,

 

I was referring to Tomasz’s earlier post.   Here’s a copy of that post.

 

Regards,

 

Dan.

 

 

~~~~~ Snip ~~~~~~

Hello,

 

There is easier to use technique, which is already shown by built-in volume code:

 

Plot( Volume, _DEFAULT_NAME(), ParamColor("Color", colorBlueGrey ), ParamStyle( "Style", styleHistogram | styleOwnScale | styleThick, maskHistogram  ), 2 );

 

 

This '2' in the end controls how tall volume histogram is. 2 means 1/2 of pane. 3 would mean 1/3 of pane.

You can parametrize it to allow free-scaling:

 

Plot( Volume, _DEFAULT_NAME(), ParamColor("Color", colorBlueGrey ), ParamStyle( "Style", styleHistogram | styleOwnScale | styleThick, maskHistogram  ), Param("1/n Height", 2, 1, 10, 0.25 ) );


Best regards,
Tomasz Janeczko

Dan:

Could you possibly supply an example of some code using the minvalue
and maxvalue?  This might help me accomplish something.
