ios - Custom Swift NSNumberFormatterStyle -

-

i'm using ios charts chart data in swift ios app including times. times stored in int variables seconds people don't want see 1 hour , 45 minutes on y axis 6300 need format it.

ios charts lets set use nsnumberformatter so

var formatter: nsnumberformatter = nsnumberformatter() formatter.numberstyle = nsnumberformatterstyle.spelloutstyle chartholder.leftaxis.valueformatter = formatter

but none of styles available suitable need. need take number of seconds , turn into, example, 1h 45m. want make custom nsnumberformatterstyle... how do this?

any appreciated.

this won't work nsnumberformatterstyle - options limited you. should do, subclass nsnumberformatter, , override stringfromnumber: function. there can string manipulation want.

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/...
