text function in 3d plots

I have a plot with 4 subplots, all of which are 3d surface plots. After I plot them, I need to insert text to the plot, showing the regression equations, Rsquare, name for each subplot.

The issue is that the coordinate system seems to be very weird. Instead of horizontal and vertical, the axis has an angle.

Is there a better solution than "text"?

Thanks.

You could put your equation as the title of the plot if you don't have one.

Thank you for the tip. That will work, although I want more flexibility :-)

What's more flexibility?

You can vary the axis orientation with the view function. (It’s easy to come up with aesthetically pleasing orientation using the tools in the figure window itself. The azimuth and elevation coordinates display in the lower left corner of the window.)

You can also use the 'Rotation' attribute in text to change the (apparent) orientation of the displayed text.

For example:

[X,Y] = meshgrid(-10:10);
Z = (X-5).^3 + (Y+3).^3;

figure(1)
surf(X,Y,Z)
grid on
text(-5,-5,3100, '\bff(x,y) = (x-5)^2 + (y-2)^2', 'Rotation',+15)
view([-53 +26])

Thank you. Looks like that's the only way to go.
