Hello,

Normally this set-up provides a black surface but for this input-file the Facecolorsentences seems inactive since I get the same plot if I remove the two sentences. I like the way of the plot but the coloors are not right. A drayscale would be best

load thermoeqall

x3=thermoeqall(:,1)

y3=thermoeqall(:,2)

z3=thermoeqall(:,3)

xv = linspace(min(x3), max(x3), 1000);

yv = linspace(min(y3), max(y3), 1000);

[X,Y] = meshgrid(xv, yv);

Z = griddata(x3, y3, z3, X, Y);

A =  mesh (X, Y, Z);

set(A(1),'FaceColor','k')

meshc(X,Y,Z)

grid on

xlabel('Temperature (K)','Fontsize',8)

ylabel('Pressure (Bars)','Fontsize',8)            

zlabel('Hydrate Gibbs free energy (kJ/mole)','Fontsize',10)            

set(gca,'fontsize',10)

I'm unable to reproduce your results. Obviously I don't have the starting dataset (hyd3D). but if I try to produce a meshc with a dummy dataset, and then follow the meshc with your annotation commands, I get results that show the axis labels. 

[X, Y] = meshgrid (linspace (-3, 3, 40));
Z = sqrt (abs (X .* Y)) ./ (1 + X.^2 + Y.^2);
meshc (X, Y, Z);
xlabel ("Delta x",'Color',"k",'fontsize',10)
ylabel ("T (K)",'Color','k','fontsize',10)          
zlabel ("Diff. (kJ/mole)",'Color','k','fontsize',10)          
set(gca,'fontsize',10)

What version of Octave, operating system, and graphics toolkit are you running?     (type graphics_toolkit at the command line).  Can you try the plot using other toolkits?  

graphics_toolkit('qt')

graphics_toolkit('fltk')  

graphics_toolkit('gnuplot')  

and see if you get the same or different results?  On my system (Octave 6.2.0 on windows) i get the same results showing axis labels using all three with all three toolkits, but it might help us determine what's causing your error.
