3 Histograms on one axis - Matplotlib python -


i trying create graph has 3 histograms on 1 axis. want them overlap each different color. insides semi-transparent.

whenever use multiple colors rgb alpha 0.5, colors overlap , create nasty color.

how portray 3 graphs without producing nasty color? still want graphs overlap in same nature, in way aesthetically pleasing. have seen graphs overlap, can still see each histograms color distinctly. thanks

you may use colors call "good graph" follows:

import matplotlib.pyplot plt import numpy np; np.random.seed(42)  x1 = np.random.rand(15)*3 x2 = np.random.rayleigh(size=15) x3 = np.random.binomial(3,0.7,size=15)  bins= np.linspace(0,4,11) kw = dict(bins=bins, histtype='step', fill=true) plt.hist(x1, fc=(.14,.57,.14,.4), ec=(.14,.57,.14, 1), **kw) plt.hist(x2, fc=(.16,.16,1.0,.4), ec=(.16,.16,1.0, 1), **kw) plt.hist(x3, fc=(1.0,.14,.14,.4), ec=(1.0,.14,.14, 1), **kw)  plt.show()

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
