Plotting in a chart

Olivia · 3 March 2022 10:03

Hi everyone,

I'm making a script in which I want to process data in a chart. I've already read on the forum that if you want to plot something over a specific time base you should pass it in the form below.

However, I can't figure out how to do this. I would like to plot L1 over the corresponding time in this script.

Someone who can help me please? (If it is easier, L1 and L2 and L3 can be in 1 chart to)

this is how i tried to do it:

and lastly, I was also wondering if there is a fixed range on the Y axis. eg 0 - 250.

Thanks in advance !

Hi Olivia, there are lots of examples around this forum of transforming a dataset to send to a chart.

Your task is just a JavaScript or JSONata transformation from

Olivia:

it passes the function

to this format..

Hi @Steve-Mcl , When i change it to that format, i think i get the correct outcome but the chart isnt what it should be...

Do you see what i did wrong ?

Difficult to test without sample data but this should get you closer...

const rotated = {
    Tijd:[],
    L1: [],
    L2: [],
    L3: [],

}

const chartData = [{
    "series": ["L1", "L2", "L3"],
    "data": [ ],
    "labels": [""]
}]

const APIdata = msg.payload.consumptions;
for (var i = 0; i < APIdata.length; i++) {

    rotated.Tijd[i] = APIdata[i].timestamp
    rotated.L1[i] = APIdata[i].voltages[0]
    rotated.L2[i] = APIdata[i].voltages[1]
    rotated.L3[i] = APIdata[i].voltages[2]

    chartData[0].data.push([
        { "x": rotated.Tijd[i], "y": rotated.L1[i] },
        { "x": rotated.Tijd[i], "y": rotated.L2[i] },
        { "x": rotated.Tijd[i], "y": rotated.L3[i] },
    ])
}

msg.rotatedData = rotated;
msg.payload = chartData;

return msg;

Olivia · 4 March 2022 09:41

There is sampledata in the first mesage

Steve-Mcl · 4 March 2022 09:44

No, the first export is a function only. The 2nd is a chart only.

Steve-Mcl · 4 March 2022 09:46

Try the function i wrote - does it work?

PS: I just corrected a typo 10 secs ago (you might need to copy the function again)

Olivia · 4 March 2022 09:52

It kinda works... The timestamp does work but i should get 3 lines, 1 for L1 1for L2 and 1 for L3 and now it gives met 19 different lines.

This is the data comming from the API:

Hi @Steve-Mcl , one more question, do you know what all those undefined labels are ?

Steve-Mcl · 4 March 2022 10:55

Not without seeing your final flow.

Can you capture the payload, add it to an inject and re-create this consistently as a demo flow?

If so, share that demo flow & I will have a look.

Replace your function code with this...

const rotated = {

    L1: [],
    L2: [],
    L3: [],

}

const chartData = [{
    "series": ["L1", "L2", "L3"],
    "data": [
        [],
        [],
        []
    ],
    "labels": [""]
}]

const APIdata = msg.payload.consumptions;
for (var i = 0; i < APIdata.length; i++) {

    rotated.Tijd[i] = APIdata[i].timestamp
    rotated.L1[i] = APIdata[i].voltages[0]
    rotated.L2[i] = APIdata[i].voltages[1]
    rotated.L3[i] = APIdata[i].voltages[2]

    chartData[0].data[0].push({ "x": rotated.Tijd[i], "y": rotated.L1[i] })
    chartData[0].data[1].push({ "x": rotated.Tijd[i], "y": rotated.L2[i] })
    chartData[0].data[2].push({ "x": rotated.Tijd[i], "y": rotated.L3[i] })

msg.rotatedData = rotated;
