Dzięki, ale nadal mam problem.
Dokładniej..
Kod:
this._fn = {
lng: function(d) { return d[0]; },
lat: function(d) { return d[1]; },
MeasureValue: function(d) { return d[2]; },
fill: function(d) {
var val = this._fn.MeasureValue(d);
var color;
if(val == -1){
color = this.options.color;
}else if(val >= 0 & val < 25){
color = '#6bc926';
}else if (val >= 26 & val < 50){
color = '#d1cf1e';
}else if (val >= 51 & val < 90){
color = '#efbb0f';
}else if (val >= 91 & val < 180){
color = '#ef7120';
}else if (val >= 181){
color = '#ef2a36';
}
return color;
}
};

tablica data.o powinna mieć3 kolumny [0],[1],[2] dlaczego kod daje mi taki błąd ?
z tego kodu co wstawiłem na początku. Co robię źle ?
