Show zero percent in bar chart

[#1]

Hi,

I build a bar chart in percent and need also to display zero percent (in the sniplet group2).

Names Default To Here( 1 );
dt = New Table("Test");
dt << new column ("C", numeric, Continuous);
dt << new column ("D", numeric, Continuous);
dt << new column ("E", numeric, Continuous);
:C << set values([1,2,3]);
:D << set values([1,2,3]);
:E << set values([1,0,0.5]);
dt << new column ("Percent", numeric, Continuous, Format( "Percent", 15, 3 ), Formula(:E/:D));

dt << Graph Builder(
	Size( 534, 454 ),
	Show Control Panel( 0 ),
	Variables( Y( :Percent ), Group X( :C ) ),
	Elements( Bar( Y, Legend( 4 ), Label( "Label by Value" ) ) ),
	SendToReport(
		Dispatch(
			{},
			"Percent",
			ScaleBox,
			{Min( -0.113265306122449 ), Max( 1.08673469387755 ), Inc( 0.2 ),
			Minor Ticks( 0 )}
		)
	)
);

Thanks for any help!

Hi @TWE,

I'm not aware of a way to force JMP to display the label for a truly 0 value. It's a bit of a workaround, but what I've done in the past is add a tiny amount to a value so that jmp will round to 0 and display that rounded value. For instance, using your example, by setting the value of :E[2] to 0.000000000000001 rather than 0, the 0% label displays on the graph:

Names Default To Here( 1 );
dt = New Table("Test");
dt << new column ("C", numeric, Continuous);
dt << new column ("D", numeric, Continuous);
dt << new column ("E", numeric, Continuous);
:C << set values([1,2,3]);
:D << set values([1,2,3]);
:E << set values([1,0.000000000000001,0.5]);
dt << new column ("Percent", numeric, Continuous, Format( "Percent", 15, 3 ), Formula(:E/:D));

dt << Graph Builder(
	Size( 534, 454 ),
	Show Control Panel( 0 ),
	Variables( Y( :Percent ), Group X( :C ) ),
	Elements( Bar( Y, Legend( 4 ), Label( "Label by Value" ) ) ),
	SendToReport(
		Dispatch(
			{},
			"Percent",
			ScaleBox,
			{Min( -0.113265306122449 ), Max( 1.08673469387755 ), Inc( 0.2 ),
			Minor Ticks( 0 )}
		)
	)
);

Thanks this works well!

Another possible approach can be found in this link:

It should apply to percents, but I have not tried that.
