Django: how to customize my data in pivot chart of chartit module -


in django view have:

females = demographic.objects.filter(gender__startswith='f') males = demographic.objects.filter(gender__startswith='m')

i use chartit have graph number of people per sex, in other words show females.count() , males.count().

do have idea how customize data chartit pivot chart?

currently code 1 below not working.

ds = pivotdatapool(     series=[         {'options': {             'source':demographic.objects.filter(gender__startswith='f'),             'categories':['gender'] },             'terms':{                 'sex_count':females.count(),                 }         }     ] )  pvcht = pivotchart(     datasource=ds,     series_options =           [{'options':{             'type': 'column',             'stacking': true},             'terms':[             'sex_count']}],      chart_options =           {'title': {                'text': 'total number'},            'xaxis': {                 'title': {                    'text': 'sex'}}} )

i found solution using django aggregate function. see below:

ds = pivotdatapool(     series=[         {'options': {             'source':demographic.objects.all(),             'categories':['gender'] },             'terms':{                 'sex_count':count('gender'),                 }         }     ] )  pvcht = pivotchart(     datasource=ds,     series_options =           [{'options':{             'type': 'column',             #'stacking': true             },             'terms':[             'sex_count']}],      chart_options =           {'title': {                'text': 'total number'},            'xaxis': {                 'title': {                    'text': 'sex'}}} )

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.
