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

Created: Sep 22, 2020 03:38 PM  |  Last Modified: Jun 11, 2023 4:06 AM (4651 views)

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

use the Fit y-by-x platform. 

There is an option to fit a special line.
