I am new to thingspeak. I tried creating the sample Matlab visualization from templetes "Visualize the relationship between temperature and humidity". I did no code modification. When i say save and run i get the message stating successfully executed but i dont see any chart. I am able to see the Matlab output for the first two visualizations tempete only. Is there anything that i need to do to get the other visualization active?Confused

Hi Shiva, 

Thank you for your post. What browser are you currently using?  

Thanks

After creating your MATLAB visualization app, did you go back to the channels page and click the "+Add Visualizations" and select the MATLAB visualization app you just created?

Thanks all for the support.

@akhila: I tried with Chrome and IE same results. Multiple PC's also was tried same results. I am able to see graphs from the first two samples. 

@vinod: I have included the visualization but dont see anything as well.

Later i tried not using the sample  templete and create the 2-d plot from the first set of starter code. From this section i am able to plot the data. I still dont know why "Visualize the relationship between temperature and humidity" dosent work. If i print the values just before the plot code it prints but no chart

Not sure why you are unable to see a visualization. I was able to follow these steps:

1) login to thingspeak

2) Click on Apps->MATLAB Visialization

3) New->Examples (Visualize the relationship between temperature and humidity) -> Create

4) Save and Run

I see a MATLAB Plot output.

 

I wonder if you have any browser plugins installed that are blocking the visualizations. Can you try steps 1..4 on a different computer?
