Hatch a plot in MATLAB -


i use code in order generate graph:

and must hatch outside square.

pos = [3.75 5.6 53.5 29.5];  %spatiul nemasurat axis([0 61 0 45]) %axele set(gca,'yticklabel',{'0', '7.5','11.85', '16.2', '20.55', '24.9', '29.25', '33.6', '39.3', '45'})  rectangle('position',pos,'edgecolor','black')

figure

i made function hatch_coordinates can return hatch pattern coordinates (get code @ bottom of anwser). that, plot hatch pattern on axis, plot rectangle on top of it. have set face color of rectangle hide pattern behind.

xlim = [0 61] ; ylim = [0 45] ; [x,y] = hatch_coordinates( xlim , ylim ) ; %// return coordinates plot hatch pattern plot(x,y,'k')                              %// , plot pattern, attributes want (color, linespec, etc ...) hold on ; grid off  pos = [3.75 5.6 53.5 29.5];  %spatiul nemasurat axis([0 61 0 45]) %axele set(gca,'yticklabel',{'0', '7.5','11.85', '16.2', '20.55', '24.9', '29.25', '33.6', '39.3', '45'}) rectangle('position',pos,'edgecolor','black','facecolor','w')

that give you: hatchedfig

note hatching can varied in multiple ways. angle can set changing ratio xstep/ystep, , linestyle properties available. quick example of few variations: 

xl = [0 5] ; yl = [0 5] ;  %// simple hatch, angle changed [x,y] = hatch_coordinates( xl , yl , 0.2 ) ; subplot(1,4,1) ; plot(x,y) ; grid off  %// heavy line hatching [x,y] = hatch_coordinates( xl , yl , 0.5 ) ; subplot(1,4,2) ; plot(x,y,'k','linewidth',2) ;grid off  %// light color hatching, flatter angle, dotted lines [x,y] = hatch_coordinates( xl , yl , 1 , 0.1 ) ; subplot(1,4,3) ; plot(x,y,'color',[.7 .7 .7],'linewidth',1,'linestyle',':') ;grid off  %// multi color hatching, (specify option "merge=false" ) [x,y] = hatch_coordinates( xl , yl , 0.5 , 0.5 , false ) ; subplot(1,4,4) ; plot(x,y) ;grid off

multihatch

code:

function hatch_coordinates.m :

function [x,y] = hatch_coordinates( xlim , ylim , xstep , ystep , merge ) %// function [x,y] = hatch_coordinates( xlim , ylim , xstep , ystep , merge ) %// %// return coordinates plotting hatch pattern %// angle of lines can adjusted varying ratio xstep/ystep  %% // set default options if nargin < 3 ; xstep = 1     ; end if nargin < 4 ; ystep = xstep ; end if nargin < 5 ; merge = true  ; end  %% // define base grid xpos = xlim(1):xstep:xlim(2) ; nx = numel(xpos) ; ypos = ylim(1):ystep:ylim(2) ; ny = numel(ypos) ;  %% // create coordinates nanline = nan*ones(1,nx+ny-3) ; x = [ [ xpos(1)*ones(1,ny-2) xpos(1:end-1) ] ; ...       [ xpos(2:end) xpos(end)*ones(1,ny-2) ] ; ...       nanline ] ; y = [ [ypos(end-1:-1:1) zeros(1,nx-2)]  ; ...       [ypos(end)*ones(1,nx-1) ypos(end-1:-1:2)] ; ...       nanline ] ;  %% // merge if asked if merge     x = x(:) ;     y = y(:) ; end

java - How to filter a backspace keyboard input -

i have code gives message when key number pressed: txtvalueofclause.addeventfilter(keyevent.key_typed, new eventhandler<keyevent>() { @override public void handle(keyevent t) { char ar[] = t.getcharacter().tochararray(); char ch = ar[t.getcharacter().tochararray().length - 1]; if (!(ch >= '0' && ch <= '9')) { system.out.println("the char entered not number"); t.consume(); } } }); now if press on wrong button , press backspace remove it, error message. how can add backspace input if statement? i have found answer: txtvalueofclause.addeventfilter(keyevent.key_typed, new eventhandler<keyevent>() { @override public void handle(keyevent t) { char ar[] = t.getcharacter().tochararray(); char ch = ar[t.getcharacter().tochar

java - Show Soft Keyboard when EditText Appears -

i have code in android app, alert dialog , keyboard, , when dialog shown want keyboard appear. not , not sure why? here code: final alertdialog.builder alert = new alertdialog.builder(this); alert.settitle("title"); alert.setmessage("message"); final edittext input = new edittext(this); input.setinputtype(inputtype.type_class_number); alert.setview(input); input.setonfocuschangelistener(new view.onfocuschangelistener() { @override public void onfocuschange(view v, boolean hasfocus) { if (hasfocus) { log.i(tag, "in focus"); inputmethodmanager inputmethodmanager = (inputmethodmanager) getsystemservice(context.input_method_service); inputmethodmanager.showsoftinput(input, inputmethodmanager.show_implicit); } } }); but keyboard not appear though edit text in focus, , tell appear why, doesn't come up? thanks in advance.
