sgplot with a macro variable and

[LOLO12]

Hi All, I have this part of a large data set that I have estitmated the slope and intercept and the break point on the x axis 

the issue that I'm facing I'm not able to generate a graph that has the slope on it and the slope value, and the break point on the x axis. 

the issue when I try to assign a macro the variable will read the same slope value and draw the same slope bc the slope value was repeated many times for the same case.

So this is a scatterplot of x=parcat3n y=value. Are you trying to plot a scatterplot?

I think you want to plot the line-graph. I'm assuming here that you've used a regression model?

You've output a dataset with model estimates so you should be able to plot the regression directly

proc sgplot data=sashelp.class noautolegend;
   title "Regression Line with Slope and Intercept";
   reg y=weight x=height;
run;

If it's not a regression, then what model are you using?
