Greetings. Would you please show me how to plot data on the probability window on Excel? I am working with numbers(1-39) and dates, they vary. What is X_range, Prob_range,Lower_limit and Upper_limit? If you can't or won't help me with this, direct me to where I can find the answer to this problem. Thanks.
