Chart Data Series Types

C1Chart provides the following DataSeries classes to effectively handle different data types:

BubbleSeries
DataSeries
HighLowOpenCloseSeries
HighLowSeries
XYDataSeries

The Label property in the DataSeries class represents the label for the Series name in the Chart Legend.

There are several DataSeries classes inherited from the same base class DataSeries, each of them combines several data sets depending on appropriate data nature. For instance, the XYDataSeries provides two sets of data values that correspond to x- and y-coordinates. The list of available data series classes is presented in the table below.

Class	Values properties	Value binding property
BubbleSeries	DataSeries.Values, DataSeries.ValuesSource XYDataSeries.XValues, XYDataSeries.XValuesSource	ValueBinding XValueBinding
DataSeries	DataSeries.Values, DataSeries.ValuesSource	ValueBinding
HighLowOpenCloseSeries	DataSeries.Values, DataSeries.ValuesSource, XYDataSeries.XValues, XYDataSeries.XValuesSource HighLowSeries.HighValues, HighLowSeries.HighValuesSource HighLowSeries.LowValues, HighLowSeries.LowValuesSource HighLowOpenCloseSeries.OpenValues, HighLowOpenCloseSeries.OpenValuesSource HighLowOpenCloseSeries.CloseValues, HighLowOpenCloseSeries.CloseValuesSource	ValueBinding XValueBinding HighValueBinding LowValueBinding OpenValueBinding CloseValueBinding
HighLowSeries	DataSeries.Values, DataSeries.ValuesSource XYDataSeries.XValues, XYDataSeries.XValuesSource HighLowSeries.HighValues, HighLowSeries.HighValuesSource HighLowSeries.LowValues, HighLowSeries.LowValuesSource	ValueBinding XValueBinding HighValueBinding LowValueBinding
XYDataSeries	DataSeries.Values, DataSeries.ValuesSource XYDataSeries.XValues, XYDataSeries.XValuesSource	ValueBinding XValueBinding

Each data series class may have its own default template for plotting, for instance HighLowOpenCloseSeries displays financial data as a set of lines that mark high, low, open and close values.

DataSeries Differences

There are some differences between the types of data series.

DataSeries has only one logical set of data values - Values. These are the Y-values. The X-values are generated automatically, or are specified as text labels using the Data.ItemNames property.
XYDataSeries has two sets of data values - Values (the Y-values) and XValues.

Render Mode Limitations

There are some limitations when using the fast render mode.

Labels, templates, and the PlotElementLoaded event are not supported.
It’s implemented only for Line and XYPlot charts(and their combination). These chart types are commonly used in case of large data.
