Question

当我第一次使用JUNO在JULIA中运行Plots时 savefig（路径）给出了以下错误。当我第二次运行长模拟时，错误消失。任何线索为什么会发生这种情况？

CODE

Characteristic curve
            gr()
            Plot1= plot(Se, 10.*log10.(H_vg), label= "Vangenuchten")
            plot!(Se, 10.*log10.(H_kg), label= "Kosugi")
            plot!( title= "THETA(h)", xlabel= "Se [-]", ylabel= "log10 h [cm]", linewidth=4)


            # Unsaturated curve
            Plot2= plot(Se, Kr_vg, label= "Vangenuchten")
            plot!(Se, Kr_kg, label= "Kosugi")
            plot!(title= "K(theta)", xlabel= "Se [-]", ylabel= "Kr [-]", linewidth=4)

            #Infiltration
            Infiltration_Inv2= Infiltration_Inv[i_Sample, 1: Infiltration_N[i_Sample]]
            Infiltration2= Infiltration[i_Sample, 1: Infiltration_N[i_Sample]]
            Infiltration_Hydro2 = Infiltration_Hydro[i_Sample, 1: Infiltration_N[i_Sample]]
            T2=  T[i_Sample, 1:Infiltration_N[i_Sample]]
            Plot3= plot(T2, Infiltration2, label= "Observed")
            plot!(T2, Infiltration_Hydro2, label= "Best")
            plot!(T2, Infiltration_Inv2, label= "Simulated")
            plot!(title= "INFILTRATION METHODS", xlabel= "Time [minutes]", ylabel= "Infiltration [mm/minute]", linewidth=4)

            #DθDh
            Plot4= plot(Se, DθDh_kg)
            plot!(title= "Pore Size Distribution", xlabel= "Se", ylabel= "Probality Distribution", linewidth=4)

            plot(Plot1, Plot2, Plot3, Plot4, layout=(4,1))
            savefig(Path)

据我了解，GR后端存在一个错误，它与＃34; @eval import＃backend＆＃34;相关联。在Plots代码中，如here所述现在的解决方法是在使用Plots模块的命令之后使用导入后端的附加行（在您的情况下为GR），类似于下面的代码：

＆＃13;

using Plots
import GR

#your code here

＆＃13;
