Graphs, Charts, and Plots

Bar Charts

A bar chart consists of vertical or horizontal bars that represent quantitative data. Use bar charts to compare data that is aggregated by the distinct values of a category.
You can apply grouping and create data-driven lattices. You can filter or rank your data based on a specified number of top or bottom values.

Targeted Bar Charts

A targeted bar chart is a variation of the bar chart that has target values. A target value is represented as a triangle with a line at the target value that is determined by the target role.

Waterfall Charts

A waterfall chart (also known as a progressive bar chart) shows how the initial value of a measure increases or decreases during a series of operations or transactions. The first bar begins at the initial value, and each subsequent bar begins where the previous bar ends. The length and direction of a bar indicate the magnitude and type (positive or negative, for example) of the operation or transaction. The resulting chart is a stepped bar showing how incremental changes lead to the final value of the measure.

Line Charts

A line chart shows the relationship of one or more measures over some interval, such as time or a series of ranges. You can measure a single measure (univariate analysis), or you can show the relationships among multiple measures (multivariate analysis), such as the leading or lagging relationship between advertising and sales over time. The category on the X axis of a line chart is discrete; the category on the X axis of a time series plot is continuous.
You can apply grouping and create lattices.

Pie Charts

A pie chart displays a part-to-whole relationship in a circle divided into multiple slices for each value of a category data item based on a single measure data item. Each slice represents the relative contribution of each part to the whole. In a pie chart, the legend is sorted by contribution.
In SAS Visual Analytics Designer (the designer), a pie chart does not show a slice with a missing or zero response.
Effective pie charts limit the number of slices to 5 or 6. In the designer, you can use a rank to reduce the number of slices in a pie chart. For more information, see Add a New Rank.
Note: The Other slice does not display data tip values. In addition, the Other slice always sums the included values, regardless of the aggregation method selected for the measure. For example, if the aggregation method selected is Count, then the Other slice displays the sum of the individual counts.

Scatter Plots

A scatter plot is a two-dimensional plot that shows the relationship of two measure data items. Each marker (represented by a symbol such as a dot, a square, or a plus sign) represents an observation. The marker’s position indicates the value for each observation. Use a scatter plot to examine the relationship between numeric data items. You can apply grouping by assigning a category to the Color role.
Scatter plots do not use aggregated data.

Time Series Plots

A time series plot shows an ordered sequence of values that are observed at equally spaced time intervals. A time series plot requires a date, datetime, time, or hierarchy data item that is continuous on the X axis.

Comparative Time Series Plots

A comparative time series plot uses line segments to chart two measures on different scales over time. A comparative time series plot requires a date, datetime, time, or hierarchy data item that is continuous on the X axis. The X axis is shared across both plots.

Series Plots

A series plot displays a series of line segments that connect observations of input data. A series plot can use numeric or character data on the X axis.
Note: You must create and save this custom graph object in the SAS Visual Analytics Graph Builder (the graph builder) before the object is available for use in reports.
The following example shows MPG averages for different types of vehicles:

Numeric Series Plots

A numeric series plot shows the relationship of one or more measures across a series of numeric values. A numeric series plot requires numeric data on the X axis.

Bubble Plots

A bubble plot is a variation of a scatter plot in which the markers are replaced with bubbles. A bubble plot displays the relationships among at least three measures. Two measures are represented by the plot axes, and the third measure is represented by the size of the bubbles. Each bubble represents an observation. A bubble plot is useful for data sets with dozens to hundreds of values. You can add categories to the Grouping and Lattice roles.
Note: A bubble’s size is scaled relative to the minimum and maximum values of the size variable. The minimum and maximum sizes are illustrated in the plot legend. The actual value for each bubble is displayed as a data tip. For example, the legend that is displayed in A Bubble Plot, the minimum size is 1.3 and the maximum size is 8.3.

Bubble Change Plots

A bubble change plot shows changes in two sets of measures using bubbles and directed line segments.

Treemaps

A treemap displays your data as a set of rectangles (called tiles). Each tile represents a category node or a hierarchy node. The color of each tile represents the value of the first measure. The size of each tile represents the value of the second measure. (There are two data roles for measures in a treemap—Size and Color.) For example, a sales data treemap might have tile sizes that represent the number of orders, and it might have tile colors that are derived from color gradients that represent sales.
The layout of the tiles in the treemap is dependent on the size of the display area because it uses a space-filling algorithm to lay the tiles down. This means that the same treemap might appear slightly different in the designer than it does in the viewer or on a mobile device because the aspect ratio and size available in those viewers might be different from what the original report designer sees in the designer.
Note: Treemaps allow only one category data item or hierarchy data item.

Dual Axis Bar Charts

A dual axis bar chart is a variation of the bar chart that has two measures. A measure is on each axis.

Dual Axis Line Charts

A dual axis line chart is a variation of the line chart that has two measures. A measure is displayed on both the left and right side of the Y axis. The relationship between two measures can be examined on two different scales in a dual axis line chart.

Dual Axis Bar-Line Charts

A dual axis bar-line chart is a variation of the bar chart that has two measures. A measure is on each axis, and the bar chart is overlaid by a line chart.

Dual Axis Time Series Plots

A dual axis time series plot is a variation of the time series plot that has two measures. A measure is displayed on both the left and right side of the Y axis.
For example, a dual axis time series plot can be useful when you need to display two measures that have the same unit of measurement and different scales, such as quantity ordered and returns, or when you need to display two measures that have different units of measurement, such as sales and quantity ordered.

Band Plot

A band plot draws a horizontal band with two Y values for each X value. Or, it draws a vertical band with two X values for each Y value. A band plot is typically used to show confidence, error, prediction, or control limits. The points on the upper and lower band boundaries can be joined to create two outlines. The area between the boundaries is filled.
Here are some key points about band plots:
  • You must create and save this custom graph object in the graph builder before the object is available for use in reports.
  • A band plot does not support display rules in the designer.
