openlayers 3 - How to update cluster source on wfs source -

-

i have wfs source , cluster source in vector layer. time time know changed in serverside wfs source, want update vector layer show new features. how can trigger update of wfs layer without interaction of user (especially change resolution)? clear() on cluster source or vector source or combination of did not help. changed() or map.render() did not work. trigger somehow loader-function of vector source. help!

this related known issue: https://github.com/openlayers/ol3/pull/3917

i'd suggest using change pull request above in custom build, should enable reload layer (and cluster) calling clear on base source.

alternatively, initialize new cluster source each time call clear on base source, , replace cluster source calling setsource on layer.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
