Proc Power: Plot Statement- Labeling Groupproportions in Graph

[daszlosek]

Hello Everyone,

I am trying to rename the labels for my graph so that they read "Cohort I," "Cohort II" instead of "Proportions 0.09648 0.06272," "0.09365 0.06555,", etc. Is there an easy way to do this?

Here is my code and I have also attatched a PNG of the graph:

Proc power;
twosamplefreq test = pchi
sides = 2
alpha = 0.05
groupproportions = (0.09648, 0.06272) /*35*/
(0.09365, 0.06555) /*30*/
(0.09097, 0.06823) /*25*/
(0.08844, 0.07076) /*20*/
(0.08605, 0.07315) /*15*/
(0.08379, 0.07541) /*10*/
(0.08164, 0.07756) /*05*/
ntotal = 0 200 400 600 800 1000 1200 1400 1600 1800 2000 2200 2400 2600 2800 3000 3200 3400 3600 3800 4000 4200

16800 17000 17200 17400 17600 17800 18000 18200 18400 18600 18800 19000 19200 19400 19600 19800 20000
power = .;

title 'Cohort 1 / 35% - 5% RRR';
plot
x =N
min = 200
max = 8000
xopts = (ref = 3514 crossref = yes)
vary(color);
/*ODS Output PlotContent = want;*/

run;

Thank you!

To control plot appearance I would be tempted to sent the plot info to a data set and plot that where I could and a label variable and have more control over legends and axis appearance.
