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:
Assigning Data to Roles
You can subset the data in the input data set by applying an SQL WHERE clause. In the Where
string box, enter your valid SQL syntax. Operands that are character strings must be enclosed in single or double quotation marks. To view this WHERE clause with
the resulting graph, select the Include as footnote check box.
To run the Bar-Line
Chart task, you must assign a column to the Category variable, Bar
response variable, and Line response variable roles.

|
Bar response
variable
|
specifies a numeric response variable for the bar chart.
|
|
Line response

|---|---|
|
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).
|
|
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
|
|
|
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.
