Ryo san,

The first method worked for me after I set color for each label. 😸 Like

set text/font=Helvetica/color=blue

Otherwise, Ferret won't let me use the colored label function.

The second method is a little harder for me because I didn't find some symbols for angled brackets.

By the way, are there some tricks to "draw" a longer line in a label but without really plotting the line?

Say I use

label 0 -12 0 0 .2 - -<OLR>

to label a line (-) using a negative OLR -<OLR>. They both come out as the same length. I am currently using

label 0 -12 0 0 .2 _ -<OLR> to distinguish these two lines.

Let me know if there are better tricks.

Thank you very much and stay healthy,

Xiaoyu

Dear Xiaoyu,

I am using

label 100 -12 0 0 .2 @P4- -<OLR>

to label one variable which is an integral. Turned out to be Ferret processed the brackets as single quotation marks. So it came out as -'OLR'. Any ideas on how to solve this problem?

Two solutions.

1. Use a system font:

set text/font=Helvetica
label . . .

2. With the native font, use the character codes. Look up "font" in the official manual
