How to create an editable map on thingspeak?

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.
