Radar chart Attributes

FroalaCharts will render here

Functional Attributes


These attributes let you control a variety of functional elements on the chart. For example, you can opt to show or hide data labels, data values. You can also set chart limits and extended properties.

animation


This attribute lets you set the configuration whether the chart should appear in an animated fashion. If you do not want to animate any part of the chart, set this as 0.

Type: Boolean

Range: 0/1

animationDuration


This attribute sets the animation duration of the chart. animationDuration attribute is applicable only if animation of the chart is enabled.

Default value: 1 sec

Type: Number

Range: In seconds

palette


Each chart has 5 pre-defined color palettes which you can choose from. Each palette renders the chart in a different color theme.

Type: Number

Range: 1-5

paletteColors


While the palette attribute allows to select a palette theme that applies to chart background, canvas, font and tool-tips, it does not change the colors of data items (that is, column, line, pie etc.). Using paletteColors attribute, you can specify your custom list of hex colors for the data items. The list of colors have to be separated by comma. For example, "paletteColors": "#FF0000, #0372AB, #FF5904...". The chart will cycle through the list of specified colors and then render the data plot accordingly. To use the same set of colors throughout all your charts in a web application, you can store the list of palette colors in your application globally and then provide the same in each chart JSON.

Type: String

Range: List of hex color codes separated by comma

showLabels


It sets the configuration whether the x-axis labels will be displayed or not.

Type: Boolean

Range: 0/1

showValues


Sets the configuration whether data values would be displayed along with the data plot on chart.

Type: Boolean

Range: 0/1

showLimits


Whether to show chart limit values. If not specified showYAxisValues overrides this attribute.

Type: Boolean

Range: 0/1

showDivLineValues


Whether to show div line values. If not specified showYAxisValues overrides this attribute.

Type: Boolean

Range: 0/1

labelStep


By default, all the labels are displayed on the chart. However, if you've a set of streaming data (like name of months or days of week), you can opt to show every n-th label for better clarity. This attribute just lets you do so. When a value greater than 1 (n) is set to this attribute, the first label from left and every label at the n-th position from left will be displayed. e.g., a chart showing data for 12 months and set with labelStep: 3 will show labels for January, April, July, and October. The rest of the labels will be skipped.

Type: Number

Range: 1 or above

adjustDiv


The chart automatically tries to adjust divisional lines and limit values based on the data provided. However, if you want to set your explicit lower and upper limit values and number of divisional lines, first set this attribute to false. That would disable automatic adjustment of divisional lines.

Type: Boolean
