Re: how to put square root in the plotting

[john wang]

Dmitri , how do you put char ​√ ​ inline, the special char cannot be typed from  the regular keyboard.

JokerOne, I tried gnuplot enhanced text mode, I can get the squre root, but the squre root doesn't have  the hyphen line in  the generated plotting,

it doesn't look pretty.

will "just work" with any modern gnuplot terminal (wxt, qt, pdfcairo, pngcairo, epscairo).

E.g.:
 x=linspace(0,100,101);
 y=sqrt(x);
 plot(x,y)
 text(30,7, "y = √x")
 title("y = √x")
 # Or
 #print("sqrtx.pdf","-dpdfcairo","-FCambria:18")
 print("sqrtx.png","-dpngcairo","-FCambria:18")

Should produce the attached file.
