Try an Example
Before getting started with your own dataset, you can check out an example. First, select the 'Type' menu. Hovering the mouse over the chart type icon will display three options: 1) Charts like this by Plotly users 2) View tutorials on this chart type 3) See a basic example.
Clicking the 'See a basic example' option will show what a sample chart looks like after adding data and editing with the style. You'll also see what labels and style attributes were selected for this specific chart, as well as the end result.
You can also use the data featured in this tutorial by clicking on 'Open This Data in Chart Studio' on the left-hand side. It'll open in Chart Studio.
Head to Chart Studio and add your data. You have the option of typing directly in the grid, uploading your file, or entering a URL of an online dataset. Chart Studio accepts .xls, .xlsx, or .csv files. For more information on how to enter your data, see this tutorial.
After adding data, go to the 'Traces' section under the 'Structure' menu on the left-hand side. Choose the 'Type' of trace, then choose 'Atlas Map' under 'Maps' chart type.
Now, within the panel, choose either the option 'Lat/Lon' or 'Location', based on the data format.
If 'Lat/Lon' is chosen, specify the latitude (in degrees East) and longitude (in degrees North) cooordinates from the dropdown menus.
If 'Location' is chosen, specify the coordinates in terms of location IDs (i.e., abbrevations) or names using the dropdown menu available next to the 'Locations' attribute. The coordinates, in this case, correspond to the centroid of each given location. The attribute 'Location Format' determines the set of locations used to match entries in 'Location' to regions of the map.
In this example, 'Lat/Lon' is chosen and the resulting mapbox plot can be seen below.
Notice that the data used in this example contains data points only for the USA, hence the points are populated around the USA region.
To change the view to just the USA, go to the 'Subplots' section under the 'Structure' menu and select 'USA' from the dropdown next to the attribute 'Region' under the property 'Map Projection'. This simply changes the region to the USA as opposed to a global map. Below, the 'Projection' dropdown will automatically default to 'Albers USA' then.
The 'Style' menu displays many options to modify characteristics of the overall chart layout or the individual traces. To see more options about styling the chart visit the style and layout section of the Chart Studio documentation.
Use the 'General' section under the 'Style' menu to set the plot title, and other layout properties.
To set the plot title, type the title text within the textbox provided under the 'Title' property.
Another approach is to click and then enter the title directly on the plot interface.
Use the 'Traces' section under the 'Style' menu to change the properties of the trace such as the marker (points) symbol, color or size and hoverinfo.
To change the color of the traces, choose either the option 'Constant' or 'Variable'.
If 'Constant' is chosen, all the points of the trace are colored in the same color. Then choose the color by clicking on the color palette.
If 'Variable' is chosen, each point in the trace is colored according to the data specified. Then choose the desired colorscale from the respective dropdown menu. In this plot, the option 'Variable' is chosen, as seen below.
Use the 'Color Bars' section under the 'Style' menu to change the properties of the color bar such as title, size and position, etc.
Similar to the plot title, the color bar title can also be entered directly on the plot interface.
Save and Share
To save the plot, click the 'Save' button on the left-hand side. A save modal will appear, as seen below, where you can specify the filenames and privacy settings for your plot and data grid.
