Re: how to put square root in the plotting

[Dmitri A. Sergatskov]

​if it is just simple text, you can just put char ​

√

​ inline and it

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.
