i trying create line chart in d3.js.the color of axes chart available @ runtime , can vary in vast set of colors.it possible set colors axes using css classes this . but since range of colors chart can take vast , available @ runtime, not feasible use solution.using call(yaxis).style("stroke",usercolor) sets color font use on axes labels , ticks not color of axis itself. is possible set color of axis in d3.js axis dynamically using javascript? i think might want following: d3.selectall('.axis path') .style("stroke", usercolor) .style("fill", usercolor) in case, .axis path should identifying css on axis lines (possibly put in d3 in yaxis function). need 1 of fill , stroke , try out see works you. should operate on actual axis line, rather text element

how create own class behaves like: std::cout & std::cerr . i writing mini operating system , requirement, having these modules there. the code like: mynewcoutclass mycout; // create cout behavioral class mynewcerrclass mycerr; // create cerr behavioral class mycout << somestring << endl; // prints string mycerr << somestring << endl; // prints string error these objects std::ostream s. can create own std::ostream . precisely how that'll work depends entirely on data sink, haven't specified, std::ostringstream enough started on testing code uses it. however, if literally wish reinvent std::cout , don't . data sink magic file handle stdout , can't recreate it's provided os. create std::ostream steals buffer std::cout what's point?

is there way remove title of button items in all view controllers of app? note : important thing all word. closest i've been this solution : [[uibarbuttonitem appearance] setbackbuttontitlepositionadjustment:uioffsetmake(0, -60) forbarmetrics:uibarmetricsdefault]; but mention in comment there's issue large titles being pushed right solution not valid. just set title of button "" here's example in swift self.navigationitem.backbarbuttonitem = uibarbuttonitem( title: "", style: uibarbuttonitemstyle.plain, target: nil, action: nil) to in view controllers, make baseviewcontroller include line in viewdidload method. when have viewcontroller subclass baseviewcontroller . your solution work if move x value -150, me sounds hack because still showing time, off view bounds.

i'm writing program integer input user cin>>iusersel; . if user puts in letter, program goes infinite loop. tried prevent code below, program goes infinite loop , prints out "wrong! enter #!". how can fix program? cin>>iusersel; while (ivalid == 1) { if (cin.fail()) { cin.ignore(); cout<<"wrong! enter #!"<<endl; cin>>iusersel; }//closes if else ivalid = 0; }//closes while i found information on @ correct way use cin.fail() , c++ cin.fail() question , didn't understand how use them fix issue. after cin fails need clear error flag otherwise other input operation non op. clear error flags need call cin.clear() . code become cin >> iusersel; while (ivalid == 1) { if (cin.fail()) { cin.clear(); // clears error flags cin.ignore(); cout << "wrong! enter #!" <...

when add node example, named "bob" in insert method: public void insert(string alabel){ //left recursion: if(this.getlabel().compareto(alabel) <= 0) { if (childrenleft == null) { bstreenode anode = new bstreenode(alabel,this); return; } else { childrenleft.insert(alabel); } } //right recursion else { if (childrenright==null) { bstreenode anode = new bstreenode(alabel,this); return; } else{ childrenright.insert(alabel); } } } my tree adds blank node no label on left side of treee only. there wrong (bstreenode anode = new bstreenode;)? because when hard code nodes like: bstreenode louis = new bstreenode("louis", treeroot); bstreenode bonny = new bstreenode( "bonny", treeroot); bstreenode sue = new bstreenode("anne", bonny); bstreenode sam = new bstreenode("sam",louis); bstr...

we have had occurrences sonarqube job running hours, appears hung no eta on completion in our ci environment. have used workaround solution of not aborting build job, there seems secondary process executing sonarqube on ci agent itself. have read specifying sonar.forceanalysis=true should resolve issue has been deprecated of version 3.x , there no need use analysis parameter. able proactively address , not have respond after team running sonarqube notifies of issue. there way of specifying timeout process running analysis terminate? if looking killing analysis running in ci environment after time, suggest feature offered ci environment. there no such thing in sonarqube. as side note, should have upcoming 5.2 release of sonarqube. have cut connection database analyzer means error “the project being analyzed” can not occur more. in addition, quite bunch of work done analysis job has been moved server allow run faster.
