Kendo UI Angular 2+ Chart - Series Tooltip Template - Access to Category Value and Other Data -


i'm using kendo chart component series items of type "line".

according documentation here it's possible use current value placeholder within series tooltip template.

is there possibility access current category within template well? , in case i'm binding objects instead of primitive values possible access current data item not value?

thanks

there way. documentation provided not straightforward , found confusing well.

current category can accessed declaring variable , setting category.

if using object set data of kendo-chart-series-item, other properties of object can used tooltip. use dataitem property here access other properties of data have set.

  <kendo-chart-series-item-tooltip>         <ng-template let-value="value" let-category="category" let-dataitem="dataitem">           number of children: {{ dataitem.number }}         </ng-template>   </kendo-chart-series-item-tooltip>

here each dataitem object array can set tooltip complete list of properties of tooltip can accessed can found here.

working code

<kendo-chart>       <kendo-chart-tooltip>         <ng-template kendochartseriestooltiptemplate let-value="value">           default content {{ value }}         </ng-template>       </kendo-chart-tooltip>       <kendo-chart-title text="% children conscientious objection recorded"></kendo-chart-title>       <kendo-chart-category-axis>         <kendo-chart-category-axis-item           [categories]="['1999', '2000', '2001']"           [title]="{ text: 'years' }">         </kendo-chart-category-axis-item>       </kendo-chart-category-axis>       <kendo-chart-series>         <kendo-chart-series-item type="column" [data]="testdata" field="percent" >           <kendo-chart-series-item-tooltip>             <ng-template let-value="value" let-category="category" let-dataitem="dataitem">               number of children: {{ dataitem.number }}             </ng-template>           </kendo-chart-series-item-tooltip>          </kendo-chart-series-item>       </kendo-chart-series>  </kendo-chart>

declare testdata object below in typescript file 

testdata = [{       date: 1999,       percent: 0.23,       number: 4271     },     {       date: 2000,       percent: 0.41,       number: 7624     },     {       date: 2001,       percent: 0.55,       number: 9987     }]

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
