Hey, so I made an app on app designer that reads and writes data to a thingspeak channel. So what I want to do is make a filed on my thingspeak channel that is going to be a map, I want to upload my latitude and logitude data to that map and plot the points. I have been looking for a long time and all I can find was the channel location, but I don't want that, I want to plot multiple points when I click the upload button on my app designer. Any idea on how to do that?

Okay, so I was able to make the map and to plot it I first uploaded latitude and longitude to a filed in my channel and then made a matlab Visualizations that reads the latitude and longitude from those fields then plots the map. My problem now is that it doesn't automatically update, I have to go in manually and lick save and run for it to plot it, is there anyway for it to auto update?
this is my code,
readChannelID = channelId;
fieldID1 = 2;
fieldID2 = 3;
readAPIKey = 'APiKey';
%% Read Data %%
% Read first data variable
[data1, time1] = thingSpeakRead(readChannelID, 'Field', fieldID1, 'NumPoints', 30, 'ReadKey', readAPIKey);
% Read second data variable
[data2, time2] = thingSpeakRead(readChannelID, 'Field', fieldID2, 'NumPoints', 30, 'ReadKey', readAPIKey);
gx = geoaxes;
geoplot(gx,data1,data2,'-*');
geobasemap(gx,'streets');

If you have a paid license of ThingSpeak, you can enable the "Auto Update" checkbox on the MATLAB visualization that will cause the visualization to be automatically updated up to once every 5 minutes.
If you don't have a paid license, you will need to manually refresh your browser page every 5 minutes (or less frequently) to have the map updated.

Hello i would like to make something similar to what you did but can you please explain how you made the matlab visualization and where to use that code?
Thank you.
