Creating Overlay Graphs

You can apply SuperGIS Desktop Graph Add-on to create overlay graphs. Overlay graphs refer to create a graph composed of more than two types of graphs. Integrating different numeric data into a graph can visually display the data clearly. For example, overlay graphs can plot the relationship between the estimated house prices and the real house prices in some city or the population variances in recent year within a district.

When you want to create a mixed graph by Create Graph, you can click the New Series and a new graph tab is added. Switch the graph tab, and you can set the properties of the new graph, like the layer, color, etc. To create an overlay graph, you need to decide the graph type first. For example, the first tab uses Vertical Bar, and the second tab uses Vertical Line. Then, set the properties respectively. An overlay graph is created.

NOTE: Pie charts are only applied to display the data of a field to present the relationship between one item and the whole data. Thus, pie charts cannot be used to create mixed graphs or overlay graph.
