也在z轴上查找自定义zticklabel和fontsize。最值得注意的是,使用zticks([-(R + r),0,R + r],[“-R-r”,“ 0”,“ R + r”],fontsize = 16)的直观方法无效。我使用的是Julia 4.3.0,因为这是一个较旧的项目,目前我无法完全转换为较新的版本。下面的注释行包括我尝试的其他命令,但未成功。
我这里的最终目标是在z轴上获得-0.8、0、0.8值,分别改为说“ -r”,“ 0”和“ r”。 >
using PyPlot
colormapp = "nipy_spectral"
R = 1.6;
r = 0.8;
N = 256;
dx = 2*pi/(N-1);
y = zeros(N,1); # y = phi (col) toroidal
x = y.'; # x = theta (row) poloidal
for ix = 2:N; y[ix] = (ix-1)*dx; x[ix] = (ix-1)*dx; end
cosxsqr = cos(x) .+ 0.0*y;
sinxsqr = sin(x) .+ 0.0*y;
sinysqr = 0.0*x .+ sin(y);
cosysqr = 0.0*x .+ cos(y);
Rrcosxsqr = R+r*cosxsqr;
rRrcosx = r*Rrcosxsqr[:];
Xsqr = Rrcosxsqr.*cosysqr;
Ysqr = Rrcosxsqr.*sinysqr;
Zsqr = r*sinxsqr;

pmeshtor = pcolormesh(x,y,Zsqr+r,cmap=colormapp);

zticks([-r,0,r])
#zticklabels([-r,0,r],["-r","0","r"])
#setp(ax[:get_zticklabels](),fontsize=16);
#setp(ax[:set_zticklabels](["-r","0","r"]))#,fontsize=16);
答案 0 :(得分:0)
注释命令
setp(ax[:set_zticklabels](["-r","0","r"]),fontsize=16);
有效,但仅当插入丢失的投影选项时(如图99所示)
figure(99)
ax = subplot(111, projection="3d")
