Hi,
I tried to build input object for the chart using official documentation. I read CSV file as one playload and using this function for creating data object from payload:
var dataval = [];
var i;
for (i = 0; i < msg.payload.length;i++){
// Convert to date
var s = msg.payload[i].Datum;
var sa = s.trim().replace(/\s/g,'').replace(" ","").split(".");
var fordat = sa[2] + "-" + sa[1] + "-" + sa[0];
var dat = new Date(fordat).getTime(); // Final date
// Create X,Y object
var one = {"X": dat, "Y": parseFloat(msg.payload[i].Hodnota)};
dataval.push(one);
}
var chart = [{"data": dataval,"labels": ["XXX"],"series": ["X"]}];
return chart;
Final object looks like this:
But there still aren't any visible data in chart. What is wrong?
EDIT:
- I am using NR v0.20.8
- I am using basic chart node for official Dashboard to create a line chart
