You can show labels for different items within the visualization.
Depending on the visualization type, the column to label by can contain regular
text (or numbers), a binary column with images, a geometry column, etc.
About this task
This example shows a bar chart with labels on all bars:
Tip: Labels within bar segments, pie sectors, waterfall chart
blocks, and so on, are only drawn if they fit within the segment. If no labels
are shown, try increasing the item width, using a smaller font for the label,
or removing some percentage decimals.
Note that labels shown on the axes are handled in the axis sections of
the visualization properties instead. See
Adjusting scales on axes for more
information.
Before you begin
A visualization that
supports editing of labels must be available.
Procedure
-
In the visualization properties, locate the
Labels section.
-
For some visualization types, you can select the column containing
the information to show under
Label by. Other visualization types only
support adding labels for what is shown on the axes.
-
Determine whether to
Show labels for
All or
Marked rows.
(In the visualization properties panel, you remove the Labels
card to remove the labels. In the visualization properties dialog or popover,
there is a None option for removing labels.)
-
Under
Label configurations, you can specify details
about the labels such as the placement of labels, if you want to use a
Max number of labels, whether to show actual
values or percentages, and so on. Different visualization types have different
settings. See also the first example below,
Specific visualization label settings.
If the max number of labels specified is smaller than the
available number of items, the labels will be evenly distributed.
The
Number of decimals option specifies the
number of decimals to show when percentage is used.
Note: Bar percentage usually only relevant when you have selected
the option 100% stacked bars under Appearance, and when the bars are colored by
a column or hierarchy. The number specified here will also affect the number of
decimals shown for the visualization items in the tooltip.
-
For some visualization types, you can change the
Label orientation from
Horizontal to
Vertical and vice versa, whereas in others
(pie charts), you can change the
Label position from
Inside pie to
Outside pie.
-
If the visualization has support for labels with other content
than text, you can also change the
Label rendering. See the second example below
for more information.
Results
The visualization
labels are updated.
Specific visualization label settings
For the visualization types
Line chart and
Parallel coordinate plot, you can choose to
Show line identifier and/or
Show individual values. The
Line identifier shows labels representing the
categories used to create each line (by coloring or line by). The
Individual values shows labels with the values
for all points used to create the line.
In a
Pie chart, you can choose what to show for the
pie sectors. Sector percentage show labels with the percentage of the total
that each sector represents. Sector value shows the actual value of the sector.
Sector category shows the category name defining the sector. You can skip
showing labels for smaller sectors by specifying a higher
Sector percentage threshold.
Note: In the
Scatter plot, or in a marker layer in a
Map chart specified to show pies as markers,
you have access to the Label configurations for the pies within the
Shape section of the visualization properties.
In a
Bar chart, you can show labels on the complete
bar and/or on bar segments only. If you choose to show labels on bar segments,
you can choose to show either the actual value, or the bar segments' percentage
of the total value.
In a
Waterfall chart, you can show labels on running
totals or on blocks.
The
Number of decimals option specifies the number
of decimals to show.
Note: Bar percentage is only applicable when you have selected the
option 100% stacked bars on the Appearance page, and it gives relevant
information only when the bars are colored by a column or hierarchy. The number
specified here will also affect the number of decimals shown for bar segments
in the tooltip.
In the
Tree map, the label options are located in the
Hierarchy section of the visualization
properties panel. You can select to
Show hierarchy headers and/or to
Show labels.
Showing other items, such as images, geometries or molecular
structures in a label
Depending on the type of the selected visualization you might be able
to add other items than text in the labels. If this is the case, you will have
access to the
Label rendering section when editing the labels.
Here is an example of a scatter plot with images in the labels of all
markers:
If you want to show images from a binary image column or a geometry
column in your data table, you select that column directly under
Label by. In some cases, like when you want to
show linked chemical structures, you will instead select an ID column here,
which at a later step is mapped against the desired output.
Your company might have configured some type of virtual column
producers that can take the values from the selected column and transform them
in one way or another, to produce a desired output. In that case, you will see
an entry called
Get content from, in the settings for the label
rendering. For example, you might be able to select Structure Column here, to
show molecular structures from an information link in the labels.
For embedded images in the current data table, or when fetching data
via a URL, you should leave this setting at
(Selected column).
If the selected source has some settings available, you can reach
those by clicking on the Settings button next to Get content from.
For example, this is where you would specify which information link to
retrieve structures from, if your company has enabled a virtual column producer
for showing chemical structures.
The
Show as drop-down list lets you select how the
data in the selected column should be interpreted.
For example, use
Text for plain text labels. Use
Image if there are binary images in your data
that you want to use in the labels. Use
Link if the text should be interpreted as a web
link. Use
Image from URL if the image is picked from a web
resource location. Use
Geometry if your data is a shapefile or GeoJSON
file and you want to show the geometrical shapes in the labels.
If the selected Show as method has settings that can be modified, you
can reach them by clicking Settings. See
Renderer settings for more information about
some common renderers.
If the selected label is some kind of image, you can increase or
decrease the size of the image using the slider.
