javascript - A few tables in one chart use amchart -


i have 1 question you. data chart looks like:

var chartdatafull=[] chartdata1=[{category:1, value:2},{category:2, value:3},{category:3, value:6}]; chartdata2=[{category:1, value:5},{category:2, value:1},{category:3, value:2}]; chartdata3=[{category:1, value:3},{category:2, value:9},{category:3, value:7}];  chartdatafull.push(chartdata1, chartdata2, chartdata3);

i 3 table put on 1 chart (different "value" same field "category") amchart. each represented separate column. how can do this?

using code fill graph (access multidimensional array index):

var chartdatafull=[] chartdata1=[{category:1, value:2},{category:2, value:3},{category:3, value:6}]; chartdata2=[{category:1, value:5},{category:2, value:1},{category:3, value:2}]; chartdata3=[{category:1, value:3},{category:2, value:9},{category:3, value:7}];  chartdatafull.push(chartdata1); chartdatafull.push(chartdata2); chartdatafull.push(chartdata3);

first solution:

display 1 dataset inside graph option of switching in between them.

code:

chart.dataprovider = chartdatafull[1]; //switch index here if want graph based on datasets. range (0-2).

  chart = new amcharts.amserialchart();     chart.automarginoffset = 0;     chart.dataprovider = chartdatafull[1]     chart.categoryfield = "category";     chart.startduration = 1;

second solution

this solution get's closest need's. done concataneting array's. you've mentioned arrays not static, still can adjust concat() function suit needs.

code:

chartdatafull.push(chartdata1); chartdatafull.push(chartdata2); chartdatafull.push(chartdata3); var children = chartdata1.concat(chartdata2,chartdata3);

official example

fiddle example:

you can see when displaying other dataset, placing in chart.

conclusion:

unfortunately once populate dataset using dataprovider attribute that's pretty it. you've created graph , can not modify in way insert additional data. once operation attribute filled done data population.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
