The following steps demonstrate how to create a new combined bar and line chart .
For an overview of shelves that specify this visual, see Shelves for combos.
-
Start a new visual based on the World Life Expectancy dataset.
For instructions, see Creating a visual.
-
In the VISUALS menu, find and click Combined
Bar/Line.
The shelves of the visual changed.
The mandatory shelf for Combined Bar/Line visuals is Dimension that maps to the X-axis.

Populate the shelves from the available fields (Dimensions,
Measures) in the DATA menu.
-
Under Dimensions, select

The combined bar and line visual appears.
The two legends for the Y axis match the color of the plot: the orange line represents
sum(gdp_per_capita)
and the blue bars representavg(life_expectancy)
. However, you may not be able to see the bars because the values of that measure are much smaller than the values for the line measure. To see the bars, assign a measure to a secondary axis. -
Alias the
life_expectancy
field asLife Expectancy
, and thegdp_per-capita
field asGDP Per Capita
:- Click the fields to open the FIELD PROPERTIES menu.
