Dynamic y axis range in variability chart

[#1]

I have the following variability chart and I am implementing that by Parameter

nebs = {};For Each({pChoice}, parameterChoice,lub << append(Text Box(pChoice));lub << append(neb = Number Edit Box(42));Insert Into(nebs, neb););vals = nebs << get;varchart = Variability Chart(
					Y( :Value),
					X( :Time Point, :Storage Condition, :Level ),
					Std Dev Chart( 0 ),
					By( :Parameter ),
					SendToReport(
						Dispatch(
							{"Variability Chart for Value"},
							"Variability Chart",
							FrameBox,
							{Row Legend(
								:Label,
								Color( 1 ),
								Color Theme( "JMP Default" ),
								Marker( 0 ),
								Marker Theme( "" ),
								Continuous Scale( 0 ),
								Reverse Scale( 0 ),
								Excluded Rows( 0 )
							)}
						)
					)
				)

Then, some lines below in the script I add reference lines in each chart using:

obs = varchart << XPath("//OutlineBox[contains(text(), 'Variability Chart for')]");
		count = 0;
		For Each({ob}, obs,
					
			count = count + 1;
			Report( varchart[count] )[AxisBox(1)] << Add Ref Line(vals[count], "Dotted", Red, "AC", 2);				
				);

But some Reference lines can not be observed in the chart because of the scaling of the y axis.

Is it possible to change the scaling for each parameter in this loop so that the max of the y axis range is the maximum between the reference line value or the maximum value of the parameter plus 0.1

You can send << Min / << Max to axisbox to change it's min / max values.

To get the min/max value of column for example by using Col Min/Col Max functions. Optionally you can try to access the marker segment and extract the values from utilizing  << Get Y Values
