javascript - Emulating multiple click functions or have separate clicked values based on specific areas below or above dataMin and dataMax - highcharts -


i using highstock highcharts.

i want capture min , max values based on area of chart clicked.

let's current instance of graph have min of 15 , max of 80 range of 1-100 data set. now, if click on area below 15 should able set min value in code. want 

click: function(e) {      ctrl.minselected = e.yaxis[0].value;  }

similarly if click on area above value 80, want fire same or click handler capture max value.

first, possible in highcharts? please guide if yes else let me know hwo can achieve ? thanks!

i made basic example showing how values need. actual code , logic should not hard figure out here.

the following code give clicked yvalue, , current extreme values in console. working fiddle

chart: {     events: {         click: function (event) {             console.log(event.yaxis[0].value);             console.log(chart.yaxis[0].getextremes());             this.update({yaxis: {max: event.yaxis[0].value}})          }     } }

to explain bit more:

event.yaxis[0].value gives yvalue according yaxis, see api on chart.events.click.

chart.yaxis[0].getextremes() gives yaxis extremes, both graph area extremes , data(points) extremes, see api on axis.getextremes

this.update refers chart, update lets update whatever may want on chart, see api on chart.update. here use set yaxis max value of location clicked.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
