I am very new to this application, but have managed to successfully plot some coordinates onto a map. Now, I am trying to see if there is a way to change the size of the pins or label them with how many occurrences there are at each coordinate.
For reference, my chart has zip codes, a count of zip codes, and lat and long.
Changing size, no. There is a concept of “Cluster Size” in the Map View configuration. Pins that are close together will be grouped under a single pin with a number indicating how many in the cluster. As you Zoom in the cluster will break up into additional smaller pin clusters until the zoom allows all pins to be shown individually.
As for the Label, ON A MOBILE DEVICE, when you tap a pin, there will be a panel shown at the bottom of the view with details about that pin. It is a Deck View. If you create your OWN Deck View for that data, it will be shown instead of the default one and you can then control what info is shown.
ON A DESKTOP VERSION of your app, a specialized Detail View panel is shown. I am not as familiar with how to customize this but I believe you can customize in the same way - create your own Detail View.
CAUTION - Once you start customizing these views it becomes a bit of an art form to get the exact view you want with each use case in your app. If you have such issues come back here for assistance.
I hope this helps!
