Here I am trying to trend two data vectors in a time series but it doesn't work in my node-red dashboard. I have communicated with someone who said otherwise. Can someone try it to see if the following plot is different: [image] [{"id":"2874c9cd.0b97d6","type":"inject","z":"15b37612.f7127a","name…

Here I have x being the vector of 4320 data point that is replaced t as it is used in the function node t =toTimestamp(Data+" 14:30:00"); also the return msg is msg.t=t; return msg; [image]

All I can do is repeat exactly the answer I gave the last time you asked about this , at which time you marked this answer as the solution. [image] Colin: the problem is clear. You can see that the first item in the array has x as a string containing " 1" whereas it should be the timestamp eithe…

Colin, I try to attach the csv file but it says "the file is too big (maximum size is 4096KB)." I understand that you pointed where the issue is. As I explained above there was a communication with someone whose able of running the file with ` if(payload[i].col1=="u") { var temp1={ "x": (payload…

[image] Munier: I try to attach the csv file Just post a few lines of the file. Paste it in using the </> button at the top of the forum entry window. [Edit] The flow you posted earlier is not importable, it stops in the middle. Try that again.

Sorry, but I had an internet issue. !@rProfit_Value @rPerformance1_Value @rPerformance2_Value @rPenalty_Value @rTotal_Value ! 0.0000000000E+000 0.00E+00 0.00E+00 0.00E+00 0.00E+00 !@rProfit_Value @rPerformance1_Value @rPerformance2_Value @rPenalty_Value @rTotal_Value !sisoarxdatau.csv …

(And.... please use the </> button as requested)

You did ask me to post a few lines of the file. This is how the csv file looks like. I am trying to plot u and y value with the 20 points (x) index being the timestamp Here t is the timestamp [image]

[image] Munier: I am trying to plot u and y value with the 20 points (x) index being the timestamp You say the u values are a timestamp, but they are just integer values 1, 2, 3 so what times do those values represent? Assuming, that is, that they do represent timestamps, which is a question…

Colin - as I understand it they want to plot both y and u values (as different topics) against the index in the array as a virtual timestamp. (ie number from 0 to 20). Nothing wrong with that - would be sensible to re-label the x axis format to be X to just show it as the epoch value to match.

Can someone try this flow to see if the following plot is generated without the straight line

Can you explain what that means? I don't see the timestamps in there.
