Series Types ScatterSeries
Describes settings supported by a series of the scatter type.
Specifies which data source field provides arguments for series points.
In the Cartesian coordinate system, each point is characterized by a pair of coordinates (X, Y). In the Chart widget, X's are provided by the argumentField; Y's are provided by the valueField.
Commonly, a chart contains several series, and many of them have the same argument field. In this case, assign the name of this field to the argumentField property of the commonSeriesSettings object. If a series must have a unique argument field, specify the same property, but do so in the series object within the series array.
Binds the series to a value axis.
Specifies the color of the series.
This option supports the following colors.
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
Specifies whether the series should ignore null data points.
Data points that have the null argument or value do not produce actual series points. Because of this, series of continuous types (line, spline, area, etc.) may be drawn with unnecessary gaps where missing points should have been. To remove these gaps, set the ignoreEmptyPoints option to true.
Configures point labels.
Declared in commonSeriesSettings, the label settings apply to all point labels in the chart. Declared in a series configuration object, the label settings apply only to the point labels that belong to this particular series. The series-specific label settings override the common ones.
- customizeLabel - сustomizes the appearance of an individual point label.
Specifies a limit for the number of point labels.
If the number of points in a series increases over time, there comes a time when it becomes so massive that displaying labels for them makes the chart too cluttered. In this instance, to keep the chart clear to the viewer, specify a limit for the number of point labels using the maxLabelCount option. Once this limit is exceeded, all point labels of the series will be hidden.
Configures series points in scatter, line- and area-like series.
Declared in commonSeriesSettings, the point settings apply to all points in the chart. Declared in a series configuration object, the point settings apply only to the points that belong to this particular series. The series-specific point settings override the common ones.
- customizePoint - сustomizes the appearance of an individual series point.
Specifies whether to show the series in the legend or not.
Specifies which data source field provides auxiliary data for series points.
Commonly, a chart contains several series, and many of them have the same tagField value. In this case, specify the tagField property in the commonSeriesSettings object. If a series must have a unique tagField value, specify the same property, but do so in the series object within the series array.
- series | tag - associates data with an entire series.
Configures error bars.
Error bars are used on charts to indicate an error or an uncertainty in a reported measurement. They give a general idea of how precise the measurement is.
Error bars can be generated either from concrete or calculated values. To generate one error bar, two values, high and low, are needed. If the data source of your chart provides concrete high and low values, assign the required data source fields to the highValueField and lowValueField options.
Alternatively, the error bar values can be calculated according to an algorithm. In this case, choose the needed algorithm using the type option, and specify the value to be used in calculation using the value option.
Specifies which data source field provides values for series points.
In the Cartesian coordinate system, each point is characterized by a pair of coordinates (X, Y). In a common case, X's are provided by the argumentField; Y's are provided by the valueField.
Certain series types require more than one value field, because their points are characterized by a larger number of coordinates. These series types are:
- Range-like series types
Range bar and range area require two value fields: rangeValue1Field and rangeValue2Field.
- Financial series types
Stock and candlestick require four value fields: openValueField, closeValueField, highValueField and lowValueField.
Specifies whether the series is visible or not.
