Hello,
I couldn’t find a solution to this:
I have an array with 3 columns:
column 1 = month
column 2 = number of female visitors
column 3 = number of male visitors
The number of rows depends on the number of months; if there are any visitors in that month and some months could have more than 1 occurrence.
For each month I need to calculate the total of female and total of male visitors; output must be something like this:
Totals month 1:
total female visitors = 15
total male visitors = 38
Totals month 2:
total female visitors = 28
total male visitors = 11
X no visitors at all in March
X visitors at all in April
Totals month 5:
total female visitors = 15
total male visitors = 38
…
I’ve managed to calculate the totals per entire column 1 and column 2, but can’t get the montly totals per column; could anyone advise pls? Thanks already for the tips.
[code]
var visitorsPerMonth = [
[1, 24, 15],
[1, 30, 22],
[3, 28, 41],
[5, 31, 58],
[5, 31, 58],
[5, 11, 58],
[7, 21, 38],
];
var totalColumn1 = 0;
var totalColumn2 = 0;
for(var i = 0; i < visitorsPerMonth.length; i++){
totalColumn1 = totalColumn1 + visitorsPerMonth[i][1];
totalColumn2 = totalColumn2 + visitorsPerMonth[i][2];
};
console.log(totalColumn1, totalColumn2);
total column 1 = 176
total column 2 = 290
