r - plotting data with a series of start end dates -


how go plotting data series of start end date bands?

i have dataframe looks like:

start<-as.posixct(c("2017-07-13 01:40:00 mdt", "2017-07-21 06:00:00 mdt", "2017-07-21 14:00:00 mdt", "2017-07-24 11:00:00 mdt",         "2017-07-24 12:00:00 mdt", "2017-07-25 05:00:00 mdt", "2017-07-25 17:00:00 mdt", "2017-07-26 12:00:00 mdt",         "2017-07-30 12:00:00 mdt", "2017-07-31 04:00:00 mdt", "2017-07-31 15:00:00 mdt", "2017-08-03 18:30:00 mdt",         "2017-08-03 23:30:00 mdt", "2017-08-09 05:00:00 mdt", "2017-08-09 20:00:00 mdt", "2017-08-14 09:00:00 mdt",         "2017-08-16 05:00:00 mdt", "2017-08-16 07:00:00 mdt", "2017-08-16 19:00:00 mdt", "2017-08-17 18:00:00 mdt",         "2017-08-20 05:00:00 mdt", "2017-08-23 06:00:00 mdt", "2017-08-23 14:00:00 mdt", "2017-08-24 17:00:00 mdt",         "2017-08-28 00:00:00 mdt"))  end<-as.posixct(c("2017-07-21 06:00:00 mdt", "2017-07-21 14:00:00 mdt", "2017-07-24 11:00:00 mdt", "2017-07-24 12:00:00 mdt",     "2017-07-25 05:00:00 mdt", "2017-07-25 17:00:00 mdt", "2017-07-26 12:00:00 mdt", "2017-07-30 12:00:00 mdt",     "2017-07-31 04:00:00 mdt", "2017-07-31 15:00:00 mdt", "2017-08-03 18:30:00 mdt", "2017-08-03 23:30:00 mdt",     "2017-08-09 05:00:00 mdt", "2017-08-09 20:00:00 mdt", "2017-08-14 09:00:00 mdt", "2017-08-16 05:00:00 mdt",     "2017-08-16 07:00:00 mdt", "2017-08-16 19:00:00 mdt", "2017-08-17 18:00:00 mdt", "2017-08-20 05:00:00 mdt",     "2017-08-23 06:00:00 mdt", "2017-08-23 14:00:00 mdt", "2017-08-24 17:00:00 mdt", "2017-08-28 00:00:00 mdt",     "2017-09-28 13:00:00 mdt"))  rate<-c(1485, 0, 1485,  880, 1485, 0, 1485, 1100, 1485, 0, 1485, 1483, 1485, 0, 1485, 1419, 880, 0, 1419, 1485, 1419, 0, 1100, 419, 1100)  df<-data.frame(start, end, rate)

i plot 'rate' on y-axis , dates on x-axis. there method go doing in ggplot or plotting package?

note: end date when next rate starts. also, line chart.

i think it...

library(ggplot2) ggplot(df)+     geom_rect(aes(xmin=as.posixct(as.character(start)),                   xmax=as.posixct(as.character(end)),                   ymin=0,                   ymax=rate))

enter image description here

alternatively, line plot, try

ggplot(df)+     geom_segment(aes(x=as.posixct(as.character(start)),                      xend=as.posixct(as.character(end)),                      y=rate,                      yend=rate), size=2)

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
