python - Heatmap with varying y axis -


i create visualization upper part of this image. essentially, heatmap each point in time has fixed number of components these components anchored y axis means of labels (that can supply) rather first index in heatmap's matrix.

i aware of pcolormesh, not seem give me y-axis functionality seek.

lastly, open solutions in r, although python option much preferable.

i not sure if understand meaning correctly, looking @ picture have linked, might best off roll-your-own solution.

first, need create array heatmap values have on row each label , 1 column each time slot. fill array nans , write whatever heatmap values have correct positions.

then need trick imshow bit scale , show image in correct way.

for example:

# create masked data a=cumsum(random.random((20,200)), axis=0) x,y=meshgrid(arange(a.shape[1]),arange(a.shape[0])) a[y<15*sin(x/50.)]=nan a[y>10+15*sin(x/50.)]=nan  # draw image along curves imshow(a,interpolation='nearest',origin='lower',extent=[-2,2,0,3]) xd = linspace(-2, 2, 200) yd = 1 + .1 * cumsum(random.random(200)-.5)  plot(xd, yd,'w',linewidth=3) plot(xd, yd,'k',linewidth=1) axis('normal')

gives:

javascript - RequestAnimationFrame not working when exiting fullscreen switching space on Safari -

request animation frame stops working when exiting fullscreen clicking on original space's safari window. fine if fullscreen mode canceled escape key or calling cancelfullscreen(). steps reproduce: open https://dl.dropboxusercontent.com/u/769042/prezi/safari-fullscreen.html click "draw raf", kittie appears click "fullscreen", go fullscreen click "draw raf", kittie appears go space original safari was, showing "click exit fullscreen mode", click anywhere, out fullscreen click "draw raf", nothing happens what handling click calling: window.requestanimationframe(draw); which draws on canvas context: function draw() { ctx.drawimage(img, math.random()*500|0, math.random()*400|0, 100, 100); } i checked .hidden , .visibilitystate, updated correctly. tested on osx 10.9.3, safari 7.0.4 (9537.76.4). has workaround/solution other switching old settimeout? this sounds webkit bug 88940 : using reque

Python ctypes access violation with const pointer arguments -

i have api i'm trying wrap in python (2.7.6 on win7) code using ctypes. here's api: client_dllfunc bool clientapi search_exporttoclipcopy(clienthsearch handle, int channel, lpctstr filename, const time_t& from, const time_t& to, const bool* cameras, int length, bool usepassword, lpctstr password, bool includetextin = false, bool excludeplayer = false); the issue i'm having cameras argument; , i've had issue other const pointer arguments well. here's how i'm wrapping api: def search_exporttoclipcopy(self, hsearch, csearch, filename, tfrom, tto, cameras, length, usepassword, password, includetextin=true, excludeplayer=false): exporttoclipcopy = self.sdkdll.search_exporttoclipcopy exporttoclipcopy.argtypes = [c_int, c_int, c_wchar_p, c_long, c_long, pointer(c_bool), c_int, c_bool, c_wchar_p, c_bool, c_bool] exporttoclipcopy.restype = c_bool exporttoclipcopy(hsearch, csearch, filename, tfrom, tto, cameras, length, usepassword, pass
