I am trying to get a graph from my roomtemperature.
I found some examples and it took me a while to get them working but I managed.
I have a database with an ID, sensornumber, value and a sql generated timestamp.
Whatever I try, I don't see anything on my graph.
This is my flow:
```auto
[{"id":"57ae6962.0687b8","type":"tab","label":"Grafiek kamertemp","disabled":false,"info":""},{"id":"4bfec7e1.b008c","type":"template","z":"57ae6962.0687b8","name":"format query wk","field":"topic","fieldType":"msg","format":"handlebars","syntax":"mustache","template":"SELECT mw_data \nFROM meetwaarden \nWHERE mw_se_id = 1\n AND mw_timestamp > \"{{payload}}\"","output":"str","x":660,"y":80,"wires":[["a7458f1c.229c78","78527ea9.9c2d68"]]},{"id":"e555e6b6.6a363","type":"debug","z":"57ae6962.0687b8","name":"1","active":false,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":630,"y":40,"wires":[]},{"id":"a7458f1c.229c78","type":"debug","z":"57ae6962.0687b8","name":"2","active":false,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":870,"y":80,"wires":[]},{"id":"9abd05c0.629ab","type":"function","z":"57ae6962.0687b8","name":"convert","func":"if ( !msg.timestamp ) msg.timestamp = Math.round(+new Date());\n\nvar dt = new Date(msg.payload);\nvar Y = dt.getFullYear().toString();\nvar M = (dt.getMonth() + 1).toString();\nif((dt.getMonth() + 1)<=9){M='0'+M}\nvar D = dt.getDate().toString();\nif(dt.getDate()<=9){D='0'+D}\nvar H = dt.getHours().toString();\nif(dt.getHours()<=9){H='0'+H}\nvar m = dt.getMinutes().toString();\nif(dt.getMinutes()<=9){m='0'+m}\n//var S = dt.getMilliseconds().toString();\nmsg.payload = Y+'-'+M+'-'+D+' '+H+':'+m+':'+'00';\n\nreturn msg;","outputs":1,"noerr":0,"x":440,"y":80,"wires":[["e555e6b6.6a363","4bfec7e1.b008c"]]},{"id":"6ef19a5d.2508d4","type":"inject","z":"57ae6962.0687b8","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":100,"y":80,"wires":[["84775b33.2d0af"]]},{"id":"77b08af2.e488d4","type":"ui_chart","z":"57ae6962.0687b8","name":"Kamer temperatuur","group":"d3e2514d.48f4c","order":1,"width":0,"height":0,"label":"Kamer temperatuur","chartType":"line","legend":"false","xformat":"HH:mm","interpolate":"linear","nodata":"","dot":false,"ymin":"","ymax":"","removeOlder":"24","removeOlderPoints":"","removeOlderUnit":"3600","cutout":0,"useOneColor":false,"useUTC":false,"colors":["#1f77b4","#aec7e8","#ff7f0e","#2ca02c","#98df8a","#d62728","#ff9896","#9467bd","#c5b0d5"],"useOldStyle":false,"outputs":1,"x":610,"y":180,"wires":[["4373954c.03ee0c"]]},{"id":"8525cd85.66fa48","type":"change","z":"57ae6962.0687b8","name":"Format data WK","rules":[{"t":"set","p":"payload","pt":"msg","to":"(\t $series := [\t { \"field\": \"mw_data\", \"label\": \"Kamertemp\" }\t];\t $xaxis := \"timestamp\";\t [\t {\t \"series\": $series.label,\t \"data\": $series.[\t (\t $yaxis := $.field;\t $$.payload.{\t \"x\": $lookup($, $xaxis),\t \"y\": $lookup($, $yaxis)\t }\t )\t]\t }\t ]\t)","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":340,"y":180,"wires":[["ab2f4d1e.a881f8","77b08af2.e488d4"]]},{"id":"78527ea9.9c2d68","type":"mysql","z":"57ae6962.0687b8","mydb":"98a864b9.d0edb","name":"MYSQL","x":120,"y":180,"wires":[["2b2c2b71.f0d6cc","8525cd85.66fa48"]]},{"id":"2b2c2b71.f0d6cc","type":"debug","z":"57ae6962.0687b8","name":"3","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":310,"y":240,"wires":[]},{"id":"ab2f4d1e.a881f8","type":"debug","z":"57ae6962.0687b8","name":"4","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":530,"y":240,"wires":[]},{"id":"84775b33.2d0af","type":"function","z":"57ae6962.0687b8","name":"Criteria","func":"var timeE = msg.payload;\n//Restrict the query to pull the last 24hrs\n//of data instead of the whole db\nmsg.payload = (timeE - (1000*60*5));\n node.status({text:msg.payload});\nreturn msg;","outputs":1,"noerr":0,"x":260,"y":80,"wires":[["9abd05c0.629ab"]]},{"id":"4373954c.03ee0c","type":"debug","z":"57ae6962.0687b8","name":"5","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":810,"y":240,"wires":[]},{"id":"d3e2514d.48f4c","type":"ui_group","z":"","name":"Grafieken","tab":"e62eb9b.f9d3cc8","order":2,"disp":true,"width":"6","collapse":false},{"id":"98a864b9.d0edb","type":"MySQLdatabase","z":"","name":"","host":"127.0.0.1","port":"3306","db":"Huismanager","tz":""},{"id":"e62eb9b.f9d3cc8","type":"ui_tab","z":"","name":"Grafieken","icon":"dashboard","order":2,"disabled":false,"hidden":false}]
```
this is what is displayed by debug3:
```auto
5-4-2020 13:36:24node: 3
SELECT mw_data FROM meetwaarden WHERE mw_se_id = 1 AND mw_timestamp > "2020-04-05 13:31:00" : msg.payload : array[6]
array[6]
0: object
mw_data: "21.84"
1: object
mw_data: "21.85"
2: object
mw_data: "21.84"
3: object
mw_data: "21.85"
4: object
mw_data: "21.87"
5: object
mw_data: "21.92"
```
I tried to modify the javascript in the "Format data WK" but I am sure I do something wrong (otherwise it would have worked)
Can anybody give me some hint how to get this working?

If you want to display an array of data, you need to provide the x-axis (time) and a value for the y-axis.
See [the documentation](https://github.com/node-red/node-red-dashboard/blob/master/Charts.md)

I cannot figure out how to do it with that info.
I tried the JSONata excercise but I do not understand anything of it

The chart accepts 3 types of data:
timebased, non-time based, (and/or) live data
Do you want a line or barchart ?
For a timebased line chart `msg.payload` needs to be formatted like (example has 3 series, you have only 1):
```auto
[{
"series": ["A", "B", "C"],
"data": [
[{ "x": 1504029632890, "y": 5 },
{ "x": 1504029636001, "y": 4 },
{ "x": 1504029638656, "y": 2 }
],
[{ "x": 1504029633514, "y": 6 },
{ "x": 1504029636622, "y": 7 },
{ "x": 1504029639539, "y": 6 }
],
[{ "x": 1504029634400, "y": 7 },
{ "x": 1504029637959, "y": 7 },
{ "x": 1504029640317, "y": 7 }
]
],
"labels": [""]
}]
```
So your array with objects needs to be reformatted as such, either with a function node or jsonata.
On google you can find many examples on how to deal with arrays/objects and rewriting them. The `x` values are unix timestamps. The query should include the timestamps (eg. SELECT mw\_timestamp,mw\_data) to make it easier, the database can also convert the timestamp directly in the correct format (ie; select UNIX\_TIMESTAMP(mw\_timestamp) - depending on the type of database and correct timestamp format)

Sorry, but all I can find as examples are different layouts. I tried JSONata but that gives no output either. And the problem is that now the timestamp has a label UNIX\_TIMESTAMP(mw\_timestamp).
I am getting desperate.
And there are a lot of beginners who have problems with this so this is not easy. I think I have to skip graphs.

Provide the following and we'll show you how...
- Your SQL query (include TOP 10 to limit size to small sample)
- Sample output data - as copied from the a debug output
- What graph style you want (line/bar)
- What field the X value is, what field the Y value is

Which gives me at debug 4:
```auto

array[1]
0: object
series: "Kamertemp"
data: array[6]
0: object

y: "23.65"
1: object

x: 1586355249
y: "23.67"
5: object
x: 1586355309
y: "23.67"
```
I now have the x and the y and still the graph is empty...
Is now the timestamp (x) too small?
This is what I have in my Format data WK:
```auto
(
$series := [
{ "field": "mw_data", "label": "Kamertemp" }
];
$xaxis := "UNIX_TIMESTAMP(mw_timestamp)";
[
{
"series": $series.label,
"data": $series.[
(
$yaxis := $.field;
$$.payload.{
"x": $lookup($, $xaxis),
"y": $lookup($, $yaxis)
}
)
]
}
]
)
```
I was a little desperate, but cannot give up 😉 And time enough through covid-19....

Forgot you need to have the timestamp in nano seconds, could you try UNIX\_TIMESTAMP(mw\_timestamp)\*1000

I found this to multiply by 1000:
```auto
(
$series := [
{ "field": "mw_data", "label": "Kamertemp" }
];
$xaxis := "UNIX_TIMESTAMP(mw_timestamp)";
[

}
]
)
```
Now I have 🙂 (yes, 13 digits)
```auto
data: array[6]
0: object
x: 1586363049000
y: "23.54"
```
and still no line in the graph....

Don't forget the labels field (even if not used).
And series needs to be an array (same for labels)

Hi Warnert, I've got it cooking here, this is the raw data off my temperature sensor (a Philips Hue Motion sensor)
`{"celsius":19.44,"fahrenheit":66.99,"deviceValue":1944.0000000000002,"updated":"2020-04-08T19:34:01+01:00"}`
I then pass this to a function node
```auto
return [
{ payload: msg.payload.celsius },
];
```
and then to a dashboard gauge and chart.
Hope this helps

Yes but he wants timeseries, not a single value.

Ok, I found something. This is now my JSONata:
```auto
(
$series := [
{ "field": "mw_data", "label": "Kamertemp" }
];
$xaxis := "UNIX_TIMESTAMP(mw_timestamp)";
[
{
"series": [$series.label],
"labels": [$series.label],
"data": $series.[
(
$yaxis := $.field;
$$.payload.{
"x": $lookup($, $xaxis)*1000,
"y": $lookup($, $yaxis)
}
)
]
}
]
)
```
In the debug window I get now:
```auto
8-4-2020 22:37:05node: 4
SELECT UNIX_TIMESTAMP(mw_timestamp),mw_data FROM meetwaarden WHERE mw_se_id = 1 AND mw_timestamp > "2020-04-08 22:32:00" : msg.payload : array[1]
array[1]
0: object
series: array[1]
labels: array[1]
data: array[5]
0: object
x: 1586377929000
y: "22.08"
1: object
2: object
3: object
4: object
```
So as you said series and labels are now arrays, but still no line 😥

```auto
[{"series":["Kamertemp"],"labels":["Kamertemp"],"data":[{"x":1586379130000,"y":"22.02"},{"x":1586379190000,"y":"22.01"},{"x":1586379250000,"y":"21.98"},{"x":1586379310000,"y":"21.99"},{"x":1586379370000,"y":"21.98"},{"x":1586379430000,"y":"21.99"}]}]
```

the values are strings, should be numbers
