Bar Chart 2 decimals

[Mrous]

Hi,
I made a bar chart with this data. And I would like to have the value CUMULWATT with only 2 decimals.
Here is my code, but it doesn't work ..

Edit Function Node

var m = {};
m.labels = ;
m.data = ;
m.series = ["Euros"];
var arrayLength = msg.payload.length;
for (var i = 0; i < arrayLength; i++) {
m.labels.push((msg.payload[i].fecha3));
m.data.push(msg.payload[i].CUMULWATT*0.00018).toFixed(2);
}
return {payload:[m],topic:msg.topic};

Thank you

I understand that value.toFixed(2) will give you a string. As you want to get a number probably you have to convert the result to float again. Something like
parseFloat(value.toFixed(2)). I can´t test right now though.

@Mrous

m.data.push(msg.payload[i].CUMULWATT*0.00018).toFixed(2)

You would be converting the length of the array you just pushed to. As push will return the array length.

The toFixed needs to be inside the push ( ). Would probably be better to use Math.round()
