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
