Polar Graphs

A polar graph is a circular scatter graph. In a polar graph, as in a scatter graph, data is represented by the location of data markers. In a polar graph, the plot area, where the markers appear, is circular.

Standard use of a polar graph

You use polar graphs to show correlations between:

Like scatter graphs, polar graphs are especially useful when you have a number of data items and you want to see the general relationships. Use polar graphs rather than scatter graphs when the data might have a directional aspect.

Available varieties of polar graphs

Only one variety of polar graph is available. The constant is POLAR.

Graph properties for polar graphs

The DepthRadius and DepthAngle properties of the Graph object together specify whether a polar graph appears to have depth.

Data structure of a polar graph

The following figure shows the data structure of a polar graph. This graph is populated with the Promotional Expense and Sales measures (in that order).

Sample polar graph

The data structure for polar graphs is as follows:

Each data marker in a polar graph represents two column values:

Data guidelines for polar graphs

Polar graph data has the following guidelines:

Example: Polar graph data

The following polar graph is populated with the Promotional Expense and Sales measures, in that order. For simplicity in this example, each series of data has only one marker in it. Normally, polar graphs have a number of markers.

Simple polar graph

The following crosstab shows the same data as the graph. Notice that there are two columns of data for each marker in the graph. This picture assumes that isDataRowShownAsASeries returns true.
