The linear scale is use to chart numerical data. It can be placed on either the x or y axis. The scatter chart type automatically configures a line chart to use one of these scales for the x axis.

As the name suggests, linear interpolation is used to determine where a value lies on the axis. The following options are provided by the linear scale. They are all located in the ticks sub options. These options extend the common tick configuration. Given the number of axis range settings, it is important to understand how they all interact with each other.

The suggestedMax and suggestedMin settings only change the data values that are used to scale the axis. These are useful for extending the range of the axis while maintaining the auto fit behaviour.

In this example, the largest positive value is 50, but the data maximum is expanded out to However, because the lowest data value is below the suggestedMin setting, it is ignored. When these are set, some data points may not be visible.

If set, the scale ticks will be enumerated by multiple of stepSizehaving one tick per increment. If not set, the ticks are labeled automatically using the nice numbers algorithm. This example sets up a chart with a y axis that creates ticks at 0, 0. Linear Cartesian Axis The linear scale is use to chart numerical data. Tick Configuration Options The following options are provided by the linear scale. Name Type Default Description beginAtZero boolean if true, scale will include 0 if it is not already included.

Axis Range Settings Given the number of axis range settings, it is important to understand how they all interact with each other. Step Size If set, the scale ticks will be enumerated by multiple of stepSizehaving one tick per increment. No results matching " ". Adjustment used when calculating the maximum data value.

Adjustment used when calculating the minimum data value.When creating a chart, you want to tell the viewer what data they are viewing.

To do this, you need to label the axis. The scale label configuration is nested under the scale configuration in the scaleLabel key. It defines options for the scale title. Note that this only applies to cartesian axes. It is also common to want to change the tick marks to include information about the data type.

To do this, you need to override the ticks. In the following example, every label of the Y axis would be displayed with a dollar sign at the front. If the callback returns null or undefined the associated grid line will be hidden. Labeling Axes When creating a chart, you want to tell the viewer what data they are viewing. Scale Title Configuration The scale label configuration is nested under the scale configuration in the scaleLabel key. Name Type Default Description display boolean false If true, display the axis title.

Only top and bottom are implemented. Creating Custom Tick Formats It is also common to want to change the tick marks to include information about the data type. No results matching " ". Height of an individual line of text see MDN. Font style for the scale title, follows CSS font-style options i.

Padding to apply around scale labels.The time scale is used to display times and dates. When building its ticks, it will automatically calculate the most comfortable unit base on the size of the scale. The time scale requires both a date library and corresponding adapter to be present. By default, Chart. You may wish to exclude moment and choose from other available adapters instead. The x-axis data points may additionally be specified via the t or x attribute when using the time scale.

When providing data for the time scale, Chart. See Moment. The following options are provided by the time scale. You may also set options provided by the common tick configuration.

The following time measurements are supported. The names can be passed as strings to the time. For example, to create a chart with a time scale that always displayed units per month, the following config could be used. The following display formats are used to configure how different time units are formed into strings for the axis tick marks. For example, to set the display format for the quarter unit to show the month and year, the following config would be passed to the chart constructor.

If this property is defined as a string, it is interpreted as a custom format to be used by Moment. Time Cartesian Axis The time scale is used to display times and dates. Date Adapters The time scale requires both a date library and corresponding adapter to be present. Data Sets Input Data The x-axis data points may additionally be specified via the t or x attribute when using the time scale.

Configuration Options The following options are provided by the time scale. Name Type Default Description adapters. Otherwise, it will be Sunday. See Time Units below for the allowed units.

See Time Units section below for details. Time Units The following time measurements are supported. Name Default Example millisecond 'h:mm:ss. SSS a' ' If this is a function, it must return a Moment. No results matching " ". If true and the unit is set to 'week', then the first day of the week will be Monday. If defined, dates will be rounded to the start of this unit.

If defined, will force the unit to be a certain type.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

As the name suggests, linear interpolation is used to determine where a value lies in relation the center of the axis. The axis has configuration properties for ticks, angle lines line that appear in a radar chart outward from the centerpointLabels labels around the edge in a radar chart.

The following sections define each of the properties in those sections. The following options are provided by the linear scale.

They are all located in the ticks sub options. The common tick configuration options are supported by this axis. Given the number of axis range settings, it is important to understand how they all interact with each other. The suggestedMax and suggestedMin settings only change the data values that are used to scale the axis.

If not set, the ticks are labeled automatically using the nice numbers algorithm. This example sets up a chart with a y axis that creates ticks at 0, 0. The following options are used to configure angled lines that radiate from the center of the chart to the point labels. They can be found in the angleLines sub options. The following options are used to configure the point labels that are shown on the perimeter of the scale.

They can be found in the pointLabels sub options. Linear Radial Axis The linear scale is used to chart numerical data. The following additional configuration options are provided by the radial linear scale. Configuration Options The axis has configuration properties for ticks, angle lines line that appear in a radar chart outward from the centerpointLabels labels around the edge in a radar chart.

You can set ticks. That is exactly I am looking for. I was able to get a fixed number of ticks because I only wanted numbers divisible byit's a financial chart. As I only wanted a maximum of 10 y-axis ticks at any time, this worked for me:. Upon further testing, my previous solution is not working nearly as well as I'd hoped.

Does anyone have a better solution to show a maximum of 10 ticks at a time? Skip to content. Dismiss Join GitHub today GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It defines options for the tick marks that are generated by the axis. The minorTick configuration is nested under the ticks configuration in the minor key. It defines options for the minor tick marks that are generated by the axis. Omitted options are inherited from ticks configuration.

The majorTick configuration is nested under the ticks configuration in the major key. It defines options for the major tick marks that are generated by the axis. These options are disabled by default. Styling There are a number of options to allow styling an axis. Grid Line Configuration The grid line configuration is nested under the scale configuration in the gridLines key. Name Type Default Description display boolean true If false, do not display grid lines for this axis.

If specified as an array, the first color applies to the first grid line, the second to the second grid line and so on. See MDN. This is useful when there are multiple axes and you need to control which grid lines are drawn. This is set to true for a bar chart by default. Tick Configuration The tick configuration is nested under the scale configuration in the ticks key. Name Type Default Description callback function Returns the string representation of the tick value as it should be displayed on the chart.

See callback. Omitted options are inherited from options above. Useful when ticks are drawn on chart area. Minor Tick Configuration The minorTick configuration is nested under the ticks configuration in the minor key. Major Tick Configuration The majorTick configuration is nested under the ticks configuration in the major key.
