Problem with 2 line charts

Dashboard
1

i have 2 line charts with on one tab:

grafy
grafy.png399×691 23.9 KB

the top chart is fine. 2 shows the measured quantities - indoor temperature and humidity. displayed values are highlighted above the graph.
the lower graph does not display moisture even when using the same data as in the upper graph
:frowning:

script for chart input (from DHT11):
var msg1 = {};
var msg2 = {};

msg1.payload = Number(msg.payload);
msg1.topic = "Teplota";

msg2.payload = Number(msg.humidity);
msg2.topic = "Vlhkosť";

return [msg1, msg2];

It might be elpful if you were to provide the entire flow so people could look at it to help figure out what is going wrong. Make sure to start with a line of three backtic's then your flow then another line of three backtic's

Or maybe not your entire flow, but enough to see exactly what you are doing, preferably a self contained flow that we can run to see the problem

yes. sorry. i am a new here :wink:

Not sure what is happning since i works fine for me. Try swapping the dot pin numbers and see if it flips the graphs and still shows the error.

Do you have another dht22 you could replace the one going to the second graph to check if it is a sensor problem?

hmmm .... I deleted it and re-created - it works:slight_smile:
