Basic styling of apps using custom themes

These examples show how to apply basic styling to your apps using custom themes. All properties referenced in the examples below are described in detail in Custom theme JSON properties.

Defining variables

A variable is a symbolic name associated with a value and whose associated value may be changed. They are defined in the _variables property and the variable names must be prefixed with @.

Information noteColors should be defined using hexadecimal values.
"_variables" : { "@grayscale-100" : "#FFFFFF", "@grayscale-98" : "#FBFBFB", "@grayscale-95" : "#F2F2F2", "@grayscale-90" : "#E6E6E6", "@grayscale-85" : "#D9D9D9", "@grayscale-80" : "#CCCCCC", "@grayscale-75" : "#BFBFBF", "@grayscale-70" : "#B3B3B3", "@grayscale-65" : "#A6A6A6", "@grayscale-60" : "#999999", "@grayscale-55" : "#8C8C8C", "@grayscale-50" : "#808080", "@grayscale-45" : "#737373", "@grayscale-40" : "#666666", "@grayscale-35" : "#595959", "@grayscale-30" : "#4D4D4D", "@grayscale-28" : "#474747", "@grayscale-25" : "#404040", "@grayscale-20" : "#333333", "@grayscale-15" : "#262626", "@grayscale-10" : "#1A1A1A", "@grayscale-5" : "#0D0D0D", "@grayscale-0" : "#000000", "@text" : "13px" }

Setting the basic font color

The top level color property controls all font colors in the app. If you define the color property on a lower level, for example for object titles, subtitles and footnotes, these will override the top level color definition.

"color": "@grayscale-20",

Setting the general font size

The top level fontSize property controls the font size in the app. If you define the fontSize property on a lower level, for example for object titles, subtitles and footnotes, these will override the top level fontSize definition

"fontSize": "@text",

Defining the background color of sheet titles

The top level sheet property controls the background color of the sheet title. This property holds the following definitions:

Sheet title background color definitions
Property Description
titleBackgroundColor This property defines the background color of the sheet title.
titleBackgroundGradientColor This property defines the color of the gradient within the sheet title.
"sheet": { "title": { "private":{ "titleBackgroundColor":"#ff0000", "titleBackgroundGradientColor":"#ffffff" }, "approved":{ "titleBackgroundColor":"#00ff00", "titleBackgroundGradientColor":"#000000" }, "published":{ "titleBackgroundColor":"#0000ff", "titleBackgroundGradientColor":"#ff0000" } } }

Defining the background color of the visualizations

The top level backgroundColor property controls the background color of all visualizations in the app. If you define the backgroundColor property on a lower level, for example on a specific chart type, this will override the top level backgroundColor definition.

"backgroundColor": "@grayscale-95",

Defining the data colors

The top level dataColors object holds the following color definitions:

Color definitions
Property Description
primaryColor Primary data color definition. This is the default color for data in the charts when you use auto colors.
othersColor Color definition for Others group values. The Others label may be displayed when you set a limit for a dimension in a visualization.
nullColor Color definition for null values.
selected Color property for selected values. This property appears in the selection bar and all listboxes. It also appears when making selections in the Straight table and Pivot table charts in the Visualization bundle.
alternative Color property for alternative values. This property appears in the selection bar and all listboxes.
excluded Color property for excluded values. This property appears in the selection bar and all listboxes.
selectedExcluded Color property for selected excluded values. This property appears in the selection bar and all listboxes.
possible Color property for possible values. This property appears in the selection bar and all listboxes.

Example - bar chart colors

{ "_inherit": true, "dataColors": { "primaryColor": "purple", "othersColor": "pink", "nullColor": "black" } }
The following image shows an example of bar charts using custom values for the dataColors object based on the color settings above. Here are details about how the dataColors properties are used in each of the charts.
  • The dataColors.primaryColor chart has only one dimension and the Colors property has been set to Auto. As a result, all the bars show the color set for the primaryColor property.
  • The dataColors.othersColor chart highlights the othersColor property, which is showing a pink color. The Others bar is an indication that there are other countries listed in the data but the chart has been limited to show only two bars.
  • The dataColors.nullColor chart highlights the nullColor property. In this case, the country Sweden is missing a city value in the data, which causes the associated bar to show a black color for a null value.

Bar charts with dataColor properties applied.

Three bar charts highlighting the use of dataColors properties.

Example - app selections

{ "_inherit": true, "dataColors": { "selected": "#0363ff", "alternative": "#a8c9ff", "excluded": "#ffaf03", "selectedExcluded": "#ffe58f", "possible": "#ffffff" } }
The following images show an example of the selection bar and listboxes using custom values for the top-level dataColors object. The colors in the image are based on the color settings above. Here are details about how the dataColors properties are used in each of the charts.

  • The dataColors.selected property controls the main color of field items in the selection bar, as well as selected values in listboxes. This property has been set to a dark blue color. The field values Peter and Franc are colored with this property.

  • The dataColors.alternative property controls the color of alternative values in the selection bar and listboxes. This property has been set to a light blue color. The field values Anderson and Devonshire are colored with this property.

  • The dataColors.excluded property controls the color of excluded values in the selection bar and listboxes. This property has been set to a dark orange color. Examples of field values with this color are Jane and Brown.

  • The dataColors.selectedExcluded property controls the color of selected excluded values in the selection bar and listboxes. This property has been set to a light orange color. The field value John has this color.

  • The dataColors.possible property controls the color of possible values in listboxes. This property has been set to a white color. The field value PF has this color.

Sheet containing three listboxes, with the selection bar at the top. A search menu for the table chart below the listboxes has been expanded to show that the custom property values appear in all listboxes in the user interface, not just within filter panes.
