What is a chart?

A chart is a graphical representation of tabular data. Visualizing data through charts helps to uncover patterns, trends, relationships, and structure in data that may otherwise be difficult to see as raw numbers in a table. Use charts together with maps to explore your data and help tell a story.

In ArcGIS Pro, you can do the following:

  • Make a chart of any map layers with tables, rasters, or standalone tables.
  • Interact with charts to explore your data dynamically across related maps, tables, and other charts created from the same layer.
  • Manage the charts associated with the layers in your maps.
  • Share a chart by exporting it as a graphic, adding it to a layout, or by packaging its source layer, map, or project.

Example

Below are two maps of United States counties showing information about Medicare beneficiaries in 2011. The map on the left shows variation in Medicare spending per capita, and the map on the right shows variation in the overall health of the population. Through a visual comparison we start to get a sense of the relationship between the two variables by noting where the maps have similarities and differences.

By creating a scatter plot of the same variables, we now have a clearer understanding of how Medicare spending and the health of the population are related. Based on the upward slope of the trend line, we can tell that there is a positive relationship between the two variables. And based on the R2 we know that the health of the population explains roughly 41.5 percent of the variation in Medicare spending per capita.
