How to create stacked bar chart using C3 for string data? -


i trying created stacked bar chart using c3 chart. facing problem trying plot graph string values. data looks 

var data1=["country", "denmark", "india"] var data2=["value", 1, 1] var x=["item",'item1','item2]  c3.generate({              data: {                 x:'item',          columns:[[data1],[data2]],                  type: 'bar' ,         groups: [             ['data1', 'data2']         ]     },);

i want display values using tooltip functionality of c3-chart.is there way make bar chart independent of y-axis?

thanks

if understand correctly, this: http://jsbin.com/dowogejose/1/edit?html,js,output

basically set value of 1 each country:

columns: [   ['denmark', 1],   ['india', 1] ]

then set callback function on tooltip format value lookup:

tooltip: {   format: {     value: function(value, ratio, id, index) {       var lookup = {         'denmark': 123,         'india': 456       };       return lookup[id];     }   } }

you store lookup value outside of tooltip callback, , generate columns array using object.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
