ios - Only one label appearing on a BarChart created with Charts -


i want create barchart charts library. working except labels on x axis. first label "jan" appearing on line. code 

override func viewwillappear(_ animated: bool) {         dobarchart()     }      func dobarchart(){           barchartview.drawbarshadowenabled = false         barchartview.drawvalueabovebarenabled = true         barchartview.chartdescription?.enabled = false          barchartview.maxvisiblecount = 60          let xaxis  = barchartview.xaxis         xaxis.axislinecolor = uicolor.black         xaxis.labelposition = .bottom         xaxis.drawaxislineenabled = true         xaxis.drawgridlinesenabled = false         xaxis.granularity = 1.0         xaxis.labelcount = 1        // xaxis.setlabelcount(7, force: true)         let months = ["jan", "feb", "mar", "apr", "may", "jun", "jul",]          xaxis.valueformatter = indexaxisvalueformatter(values:months)         //also, want add:            let leftaxis = barchartview.leftaxis;         leftaxis.enabled = false         leftaxis.drawaxislineenabled = false;         leftaxis.drawgridlinesenabled = false;         leftaxis.axisminimum = 0.0; // replaces startatzero = yes          let rightaxis = barchartview.rightaxis         rightaxis.enabled = false;          rightaxis.drawaxislineenabled = true;         rightaxis.drawgridlinesenabled = false;         rightaxis.axisminimum = 0.0; // replaces startatzero = yes          let l = barchartview.legend         l.enabled =  false          barchartview.fitbars = true;         barchartview.animate(xaxisduration: 0.2, yaxisduration: 1.0, easingoptionx: .easeinexpo, easingoptiony: .easeinexpo)          setdatacount(count: 7, range: 50)      }       func setdatacount(count: int, range: double){          let barwidth = 7.0         let spaceforbar =  10.0          var yvals = [barchartdataentry]()           yvals.append(barchartdataentry(x: double(0) * spaceforbar, y: 44.5))         yvals.append(barchartdataentry(x: double(1) * spaceforbar, y: 78.1))         yvals.append(barchartdataentry(x: double(2) * spaceforbar, y: 50.3))         yvals.append(barchartdataentry(x: double(3) * spaceforbar, y: 56.6))         yvals.append(barchartdataentry(x: double(4) * spaceforbar, y: 20.5))         yvals.append(barchartdataentry(x: double(5) * spaceforbar, y: 44.3))         yvals.append(barchartdataentry(x: double(6) * spaceforbar, y: 54.4))          var set1 : barchartdataset!           if let count = barchartview.data?.datasetcount, count > 0{             set1 = barchartview.data?.datasets[0] as! barchartdataset             set1.values = yvals             set1.colors = [uicolor.black,uicolor.orange,uicolor.red,uicolor.green,uicolor.yellow,uicolor.blue,uicolor.gray]             barchartview.data?.notifydatachanged()             barchartview.notifydatasetchanged()          }else{             set1 = barchartdataset(values: yvals, label: "dataset")             set1.colors = [uicolor.black,uicolor.orange,uicolor.red,uicolor.green,uicolor.yellow,uicolor.blue,uicolor.gray]               var datasets = [barchartdataset]()             datasets.append(set1)              let data = barchartdata(datasets: datasets)               data.barwidth =  barwidth;              barchartview.data = data          }     } 

add following delegate method of "iaxisvalueformatter"  , assign these delegate.  class xyz :  iaxisvalueformatter{  weak var axisformatdelegate: iaxisvalueformatter?  //add these line in func...  func dobarchart{   let xaxisvalue = linechartview.xaxis         xaxisvalue.valueformatter = axisformatdelegate         linechartview.xaxis.granularityenabled = true         linechartview.xaxis.granularity = 1.0 }  //add these method..   func stringforvalue(_ value: double, axis: axisbase?) -> string {         return yvlaues[int(value) % yvlaues.count]   } }

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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

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() .
