Dear Community,
Since few weeks it looks like I have lost the ability to move cards order in the channel view. I used to be able to to so.
I tried with different browser and even on mobile and it does not work anymore. Did missed something ? Is this feature been removed ?
Thanks.
Hello everyone,
Im trying to simulate an 3-phase inverter, and for analysis of semicondcutor switches cuurent and voltage, I witness some unusal behaviour. I have connected a current sensor to the drain to calculate and visialize drain current, but the waveform is lookibg something like in picture if instaneous overshooting when going form high to low or vice versa, and the magnitude of the overshooting pulse can reach upto 500 Amps.
Kindly, guide me what am i doing here wrong? and one more thing is that I have set the Ids current to be 63Amps for N-channel Mosfet, but the output is 42-44 Amp max, what could be the reason behind it?
Thank you in advance!!

I cannot get any of my charts to be interactive using matlab. I need to be able to zoom into a chart and I cannot get any interactivity. In its purest from shouldnt this allow me to zoom into a chart?
plot(time, data);
% Enable zooming
zoom on;

I am trying t set up a cellular Particle Boron and Sensor to track my well water levels but the data is not showing up in Thingspeak. I have activated and flashed code to the device, created a Particle account, a Thingspeak account (and channel), and a Webhook. Things mostly work as they should and I can even see the data from the sensor in my Particle Console "Events", but nothing seems to arrive in the Thingspeak Channel. I am looking for technical advice.

Ich habe das Problem das ich immer nur 1 Tag aufzeichnen kann (siehe Anhang), obwohl ich den Parameter au 15 tage gestellt habe.
Hello,
it's been a couple weeks that the webrowser client seems to have issues for me.
I can't move the chart with my mouse anymore. And the Average option doesn't do anything, it is always displaying all the datapoints.
Same with the type of points, it is stuck on line type whatever I ask.
Also it will not update the page automatically when new points are uploaded, I have to hit F5 to refresh myself.
I can still control the number of days displayed though.
I tried on brave, firefox and edge and it all behaves the same.
Edit : I see that there are already multiple threads referencing some of those issues already. So the moderator can delete the thread if he feels like it is unecessary.
Tengo semanas trabajando con la app y al subir informacion me aparece que la ultima entrada fue hace menos de un minuto pero las gráficas no se actualizan, ya intente abrir la app desde diferentes navegadores,y dispositivos, en modo incognito, desabilitar extenciones y no obtengo resultados.
Hi! I'm new to pk modeling and Matlab. Can someone guide me through how to conduct population pk modeling based on pk parameters from non-human primate studies? Much thanks!!!!
Is MathWorks going to spend 5 years starting in 2024 making Python the #1 supported language?
I'm not sure it's authentic information, and am looking forward to a high level of integration with python.
Reference:

how can I do to get those informations?
I get the following error message when using a DELETE command.
I am using the correct api_key and channel ID Error Response: { "status": "401", "error": { "error_code": "error_auth_required", "message": "Authorization Required", "details": "Please provide proper authentication details." } }
I just cannot find out what I'm doing wrong. I've used Postman and Curl apps.
Can anyone help?
I noticed a couple new replies show up on the recent poll a day or so ago, but since then, the page can't be loaded anymore in any browser I've tried.

Ich erinnere mich, dass die Visualisierungsfenster verschoben werden konnten. Das geht nicht mehr? Wer kennt den Trick?
Looking for an opportunity to practice your AI skills on a real-world problem? Interested in AI for climage change? Sign up for the Kelp Wanted challenge, which tasks participants with developing an algorithm that can detect the presence of kelp forests from satellite images.
Participants of all skill levels from anywhere in the world are welcome to compete!

This is not a question, it is my attempt at complying with the request for thumbs up/down voting. I vote thumbs up, for having AI.....
I am not sure if specific AI errors are to be reported. Other messages I just read from others here and the AI Chat itself clearly state that errors abound.
My AI request was: "Plot 300 points of field 2"
AI Chat gave me, in part:
data = thingSpeakRead(channelID, 'Fields', 2, 'NumPoints', 300, 'ReadKey', readAPIKey);
% Extract the field values
field1Values = data.Field1;
% Plot the data
plot(field1Values);
The AI code failed due to "Dot indexing is not supported for variables of this type"
So, I corrected the code thus to get the correct plot:
data = thingSpeakRead(channelID, 'Fields', 2, 'NumPoints', 300, 'ReadKey', readAPIKey);
% Extract the field values
%field1Values = data.Field1;
% Plot the data
plot(data);
I see great promise in AI Chat.

TimeControl Ran, but it didn't appiied it to channel (chart has not been updated in the right time and in the end, it did not ran, had to manually run the script by myself). And I would like to request to MathWorks to fix (modify) my chart to right time and value and investigate this problem.


I am sending data to Thingspeak chanels from an ESP8266. I am saving data on the ESP memory which is collected at 5 minute intervals . I have created a trigger function which sends the data on demand in batches from the memory, which means there could be varying number of Data points from say 10 to 50.However I have notice recently whilst my code tells me the data points have been transmitted not all get recorded in thingspeak, are there restrictions which cause this problem and if so what is the solution please?
Hi, while I can download data from the thingspeak page as csv older than 5 months, I can't read history data older than one month.
The data exists on the database.
This are my requests:
https://api.thingspeak.com/channels/667773/fields/1.json?start=2023-11-23T01:01:10.000Z
The same results. Every day the older value date is higher by one day.
Today the older value day is: 2023-11-25T02:13:46Z
Why? Is there a limit to history data loading?
This person used computer version to build a keyboard input, and used standard flag semaphore for the positions.
Flag semaphore is used mostly by sailors to be able to communicate optically over a distance; it does not need anything more than make-shift flags (but binoculars or telescopes can help.) Trained users can go faster than you might guess.
A research team found a way to trick a number of AI systems by injecting carefully placed nonsense -- for example being able able to beat DeepMind's Go game.
