matplotlib - Plot sphere with Julia and PyPlot -


recently tried plot sphere using pyplot/julia , unfortunately harder thought. there's wrong points generation, can't figure out why implementation didn't work. although fine original python code.

i've tried adapt demo2 matplotlib surface plot doc mwe:

using pyplot u = linspace(0,2*π,100); v = linspace(0,π,100);  x = cos(u).*sin(v); y = sin(u).*sin(v); z = cos(v);  surf(x,y,z)

and i'm getting this instead of the right one.

so, what's wrong in julia implementation?

x, y , z should matrices, not vectors -- otherwise have curve drawn on sphere, instead of surface itself.

using pyplot n = 100 u = linspace(0,2*π,n); v = linspace(0,π,n);  x = cos(u) * sin(v)'; y = sin(u) * sin(v)'; z = ones(n) * cos(v)';  # rstride , cstride arguments default 10 surf(x,y,z, rstride=4, cstride=4)

the curve drawn corresponds diagonal of matrices.

plot( diag(x), diag(y), diag(z), color="yellow", linewidth=3 )

sphere+curve

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
