In this simple plot
plot(x,0,2,gridlines=([1],[]))
the gridline is plotted alright. However, if I put sqrt(2) instead of 1
plot(x,0,2,gridlines=([sqrt(2)],[]))
does not work. It is strange, because I think that gridlines should behave similar as ticks. For instance, the following both two expressions work
plot(x,0,2,ticks=([sqrt(2)],[])) plot(x,0,2,ticks=([sqrt(2)],[]),gridlines=true)
Does anybody know what is the reason or how to fix it? Thanks. Javier Pérez.
