Forcing Y-intercept to zero when using line of fit in Graph builder

Yawovi — Sun, 11 Jun 2023 11:06:05 GMT

Hello all,
any idea how to force the y-intercept to zero when using line of fit in graph builder? I know this is possible in Bivariate plots but I would like to use graph builder for my purpose since I can get grouping in one single graph (with Bivariate you get mutliple plots after you specify your "by" variable)...below my code. Any suggestions very welcome! thanks!

Best regards,

Yawovi

Graph Builder(
	Size( 745, 526 ),
	Variables(
		X( :Power ),
		Y( :Name( "Concentration" ) ),
		Group X( :Location ),
		Overlay( :Color )
	),
	Elements(
		Points( X, Y, Legend( 7 ) ),
		Line Of Fit( X, Y, Legend( 12 ), Equation( 1 ) )
	)
)

use the Fit y-by-x platform.

There is an option to fit a special line.
