Bar-Line Chart Task

About the Bar-Line Chart Task

The Bar-Line Chart task creates a vertical bar chart with a line chart overlay.

You can use this task to perform the following tasks:

display and compare exact and relative magnitudes
examine the contribution of each part to the whole
determine trends and patterns in the data

Example: City and Highway Mileage by Origin

For example, you can create a bar-line chart that compares the number of miles per gallon (in the city and on the highway) that cars use depending on their country of origin. The task calculates the mean of the number of miles per gallon in the city and in the highway for each country. This bar-line chart shows that cars from Asia tend to get the highest number of miles per gallon in city and highway driving.

To create this example:

In the Tasks section, expand the Graph folder and double-click Bar-Line Chart. The user interface for the Bar-LineChart task opens.
On the Data tab, select the SASHELP.CARS data set.

Assign columns to these roles:

Role	Column Name
Category variable	Origin
Bar response variable	MPG_City
Line response variable	MPG_Highway

Assigning Data to Roles

To run the Bar-Line Chart task, you must assign a column to the Category variable, Bar response variable, and Line response variable roles.

Option Name	Description
Roles
Category variable	specifies the variable that classifies the observations into distinct subsets.
Bar response variable	specifies a numeric response variable for the bar chart.
Line response variable	specifies a numeric response variable for the line plot.
Group variable	specifies a variable that is used to group the data.
URL variable	specifies a character variable that contains URLs for web pages to be displayed when parts of the plot are selected within an HTML page.
Statistics
Mean	calculates the mean of the response variables.
Sum	calculates the sum of the response variables.

Setting Options

Option Name	Description
Title and Footnote
You can specify a custom title and footnote for the output. You can also specify the font size for this text.
Bar Details
Apply bar color	specifies the color for the bars.
Transparency	specifies the degree of transparency for the plot. The range is 0 (completely opaque) to 1 (completely transparent).
Apply bar gradient	applies a gradient to each bar. Note: This option is available only if you are running the second maintenance release for SAS 9.4 or later.
Data skin	specifies a special effect to be used on all filled bars.
Line Details
Apply line color	specifies the color for the line.
Line thickness	specifies the thickness (in pixels) of the line.
Transparency	specifies the degree of transparency for the plot. The range is 0 (completely opaque) to 1 (completely transparent).
Use solid line pattern	specifies a solid pattern for the line.
Category Axis
Reverse	specifies that the values of the tick marks are displayed in reverse (descending) order.
Show values in data order	places the discrete values for the tick marks in the order in which they appear in the data.
Show label	enables you to display a label for the axis. Enter this label in the Custom label box.
Response Axes
Use zero baseline	specifies whether to offset all lines from the discrete category values and all bars from category midpoints. By default, there is no offset.
Use uniform scale	uses the same scale for both response axes.
Show grid on left (bar) axis	creates grid lines at each tick on the axis for the bar chart.
Drop statistics suffix	removes the name of the calculated statistic in the axis label. For example, if you are calculating the mean, the axis label could be Weight (Mean).
Add plot prefix to axis labels	adds (Bar) and (Line) to the labels for the response axes.
Custom label for left (bar) axis	enables you to specify a custom label for the response axis in the bar chart. The default label is the name of the bar response variable.
Custom label for right (line) axis	enables you to specify a custom label for the response axis in the line chart. The default label is the name of the line response variable.
Legend Details
Show legend	specifies whether to display a legend in the output.
Legend location	specifies whether the legend is placed outside or inside of the axis area.
Graph Size
You can specify the width and height of the graph in inches, centimeters, or pixels.
