Hi, Rick,

Thank you for your reply. I have the following comments.
1). I research on that. Thankyou.

2). I have used GROUP= following the example. But it still appears in black, not the color related to the group variable. i tried to assign values to TEXTCOLOR. But it still does not work.

3). Strange as it may sound, a lot of times, I actually find that 32-character in dataset name is insufficient. I am doing some exploratory analysis with different combination, so I actually run out of
characters to be used in a SAS dataset! Will SAS consider allowing us to have more characters in s dataset name?

4). Reducing the font size may not always help if the end of the regression lines are at almost same point. We end up adjusting the y coordinate values by a percent of its original values. We increase the higher value of Y by a certain percent, and decrease the lower value of Y by a certain percent.

Thank you so much for your response! I have learnt so much from you!

Alice
