Overview of Visualizations

About Visualizations

The SAS Visual Analytics explorer interface displays data by using visualizations. A visualization is an interactive visual representation of your data. A visualization can be a table, a chart, a histogram, or a geographic map.

Visualization Types

You can assign any of the following types to your visualizations:

Autochart		Automatically selects the chart type according to the data that is assigned to the visualization. When you are first exploring a new data set, autocharts are useful to give you a quick view of the data. For more information, see Working with Automatic Charts.
Table		Displays the data as a table. Tables enable you to examine the raw data for each observation in the data source. You can rearrange the data columns and apply sorting. For more information, see Working with Tables.
Bar Chart		Displays the data as a bar chart. Bar charts are especially useful for comparing data according to each discrete value of a category. You can configure a bar chart with either vertical bars or horizontal bars. You can also assign grouping to the bars and create series. For more information, see Working with Bar Charts.
Line Chart		Displays the data as a line chart. A line chart is most useful for data trends over time. You can apply grouping, and create series. For more information, see Working with Line Charts.
Scatter Plot		Displays the data as a scatter plot. Scatter plots are most useful to examine the relationship between variables. In a scatter plot, you can apply statistical analysis with correlation and regression. Scatter plots also support grouping. When you apply more than two measures to a scatter plot, the visualization automatically displays a scatter plot matrix to compare each pairing of measures. For more information, see Working with Scatter Plots.
Bubble Plot		Displays the data as a bubble plot. A bubble plot displays the relationship between three measures, where two measures are represented by the plot axes and the third measure is represented by the size of the plot markers. You can apply grouping and create series for a bubble plot. By assigning a datetime data item to the plot, you can animate the bubbles to display changes in the data over time. For more information, see Working with Bubble Plots.
Histogram		Displays the data as a histogram. A histogram displays the distribution of values for a single measure. You can select the bar orientation, and select whether the distribution values are displayed as a percentage or as the row number of values. For more information, see Working with Histograms.
Box Plot		Displays the data as a box plot. A box plot displays the distribution of values for a measure by using a box. The size and location of the box indicate the range of values that are between the 25th and 75th percentile. Additional statistical information is represented by other visual features. You can create series, and select whether the average (mean) value and outliers are displayed for each box. For more information, see Working with Box Plots.
Heat Map		Displays the data as a heat map. A heat map displays the distribution of values for two data items by using a table with colored cells. If you do not assign a measure to the color data role, then the cell colors represents the frequency of each intersection of values. If you assign a measure to the color data role, then the cell colors represent the measure value for each intersection of values. For more information, see Working with Heat Maps.
Geo Map		Displays the data as a geo map. A geo map displays your data as a bubble plot that is overlaid on a geographic map. Each bubble is located at a geographic location or at the center of a geographical region. For more information, see Working with Geo Maps.
