Question

Using flow chart lib I’m plotting a graph. Below is the x and y coordinates of the graph as an array.

var plottingPoints  = [[0, 3], [4, 8], [8, 5], [9, 23], [10, 2]];

I just need to pick largest value of the y coordinate (ie 23). Please need support of expertise.

Answer 1

var plottingPoints  = [[0, 3], [4, 8], [8, 5], [9, 23], [10, 2]];
var length = plottingPoints.length;
var maxY = -Infinity;
for(var i = 0; i < length; i++)
    maxY = Math.max(plottingPoints[i][1], maxY);
