Elevation Y Axis

Would it be possible to add the undocumented options yAxisMin and yAxisMax to allow similar y axix scales to be shown on elevation profiles displayed in multiple posts/pages?

I have done this in my copy of the code by duplicating the height section of php/elevation.php :-

// Line 83 src/options.js
		// yAxisMax
		array(
			'param' => 'yAxisMax',
			'shortdesc' => __('y Axis Max',"extensions-leaflet-map"),
			'desc' => "",
			'default' => "0",
			// form input type,  pattern, help
			'values' => 'type="text" pattern="^[0-9]+$" title="'.__('number','extensions-leaflet-map').'"',
			'typ' => array('changeable','look','multielevation'),
		),

		// yAxisMin
		array(
			'param' => 'yAxisMin',
			'shortdesc' => __('y Axis Min',"extensions-leaflet-map"),
			'desc' => "",
			'default' => "0",
			// form input type,  pattern, help
			'values' => 'type="text" pattern="^[0-9]+$" title="'.__('number','extensions-leaflet-map').'"',
			'typ' => array('changeable','look','multielevation'),
		),

I am not sufficiently knowledgable to be sure if this is the correct way to do it and what the defaults should be (‘undefined’ in src/options.js). It would also be nice not to have to remember to redo this if I update the WP plugin.

Many thanks,

Simon
