Still having the same output, even with that call:

load wind

ymin = min(y(:));
ymax = max(y(:));
zmin = min(z(:));
xrange = linspace(xmin,xmax,8);
yrange = linspace(ymin,ymax,8);
zrange = 3:4:15;
[cx,cy,cz] = meshgrid(xrange,yrange,zrange);
coneplot(x,y,z,u,v,w,cx,cy,cz,5);

fig2plotly(gcf, 'offline', false, 'TriangulatePatch', true);
