• 1: auto
• 2: hide labels

Default: 1

gridLine

Type: Object

Grid line settings.

compressionResolution

Type: Integer

Scatter plot resolution settings for compressed data.

Default: 5

color

Type: Object

Most color options for visualizations are set in the color object in the options. You activate custom coloring by setting "auto": false which turns off auto-coloring.

If "auto": true, no other properties need to be defined in the color object.

The following parameters can be set in the color object:

auto

Type: Boolean

Set to use automatic coloring.

When "auto": true, color settings are based on the visualization used and the number of dimensions and measures, that is, the settings are not fixed, but are dependent on the data input.

Default: true

mode

Type: String

Sets the coloring mode for the visualization when auto-coloring has been switched off ("auto": false). Can be one of:

• primary: a single color (by default blue) is used for all items in the chart. In visualizations that do not benefit from multiple colors (bar charts with one dimension and scatter plots), single color is the default setting.

• byDimension: coloring is based upon the amount of dimension values. Details are set in the byDimensionDef property.

  Information notebyDimension can only be used in conjunction with an attribute dimension on the dimension to color by, as shown in the example below.
  { "qDef": { "qFieldDefs": [ "NetScoreName" ] }, "qAttributeDimensions": [ { "qDef": "NetScoreName", "id": "colorByAlternative", "label": "Year" } ] }

• byExpression: coloring is based on an expression, which in most cases is a color code. Details are set in the expressionIsColor, expressionLabel and colorExpression properties.

• byMeasure: coloring is based on the measure value. Details are set in the byMeasureDef property.
• byMultiple: can be used when more than one measure is used. By default, 12 colors are used for the dimensions. The colors are reused when there are more than 12 dimension values.

useBaseColors

Type: String

Only applicable when "mode": "primary" or "mode": "byMultiple" has been defined.

Use colors encoded in master items. Should only be defined when a master dimension or master measure used in the visualization has a color assigned to it.

One of:

• off
• measure: use colors encoded in master measure.
• dimension: use colors encoded in master dimension.

Default: off

singleColor

Type: Integer

Deprecated. Use paletteColor instead.

Set to use single color.

Default: 3

paletteColor

Type: Object

The paletteColor object is used to define the color when you color by single color ("mode": "primary"). It has the following properties:

persistent

Type: Boolean

Set to true to use persistent colors on data points between selection states. Only applicable when using one dimension and when "mode": "byDimension" or when "mode": "byMultiple".

Default: false

expressionIsColor

Type: Boolean

Set to true to define whether the result of the expression is a valid CSS3 color.

Only applicable when "mode": "byExpression".

Default: true

expressionLabel

Type: String

Defines the label on tool tips when using a coloring expression. Only applicable when "mode": "byExpression" and only used if "expressionIsColor": false

colorExpression

Type: Value Expression Container

Sets the color expression to be used when "mode": "byExpression" is defined.

Supported formats:

• RGB
• ARGB
• HSL

Example:  

measureScheme

Type: String

Color scheme when "mode": "byMeasure". Can be one of:

• sg: (sequential gradient) the transition between the different color groups is made using different shades of colors. High measure values have darker hues
• sc: (sequential classes) the transition between the different color groups is made using distinctly different colors.
• dg: (diverging gradient) used when working with data that is ordered from low to high, for instance, to show the relationship between different areas on a map. Low and high values have dark colors, mid-range colors are light.
• dc: (diverging classes) can be seen as two sequential classes combined, with the mid-range shared. The two extremes, high and low, are emphasized with dark colors with contrasting hues, and the mid-range critical values are emphasized with light colors.

Default: sg

useMeasureGradient

Type: Boolean

Set to true if you want to apply the colors defined for library measures when used. Only applicable if "mode": "byMeasure".

Default: true

dimensionScheme

Type: String

Color scheme when "mode": "byDimension" or "mode": "byMultiple". Can be one of:

• 12: 12 colors where all can be distinguished by people with vision deficiency.
• 100: 100 colors where not all can be distinguished by people with vision deficiency

Default: 12

useDimColVal

Type: Boolean

Set to true if you want to apply the colors defined for library dimensions when used. Only applicable if "mode": "byDimension".

Default: true

reverseScheme

Type: Boolean

Set to true to reverse the color scheme.

autoMinMax

Type: Boolean

Set to false to define custom color range. Custom color range is only applicable when coloring is by measure ("mode": "byMeasure") or by expression ("mode": "byExpression").

When coloring is by expression, "expressionIsColor": "false" must be set for custom color range to work.

Default: true

measureMin

Type: Value Expression Container

Set the min value for the color range.

Only applicable if autoMinMax: false. Can be used in conjunction with measureMax or by its own.

measureMax

Type: Value Expression Container

Set the max value for the color range.

Only applicable if autoMinMax: false. Can be used in conjunction with measureMin or by its own.

X axis settings.

yAxis

Type: Object

Y axis settings.

navigation

Type: Boolean

Set to true to display navigation UI.

Example using qlik-visual

In this example we create a basic scatter plot, containing one dimension and two measures. The measures have basic number formatting applied and a title is added to the scatter plot.
