Line Chart

A line chart displays information as a series of data points connected by straight line segments. There are three different types of line charts offered by Core Suite for creating line charts: normal, stacked, and 100% Stacked.

• Normal line charts describe the data as line segments.
• Stacked charts show lines of related data, one on top of the other.
• 100% stacked charts are similar to stacked charts, but express its data as percentages.

Line Series

The LineSeries, StackedLineSeries, and Stacked100PercentLineSeries abstract classes are the parent classes for line charts depending upon if the data is stacked or not. As these classes are abstract, you must create one of the following concrete classes implementing a line series.

• IndexedLineSeries
• IndexedStackedLineSeries
• Indexed100PercentStackedLineSeries
• DateTimeLineSeries
• DateTimeStackedLineSeries
• DateTime100PercentStackedLineSeries

Indexed

When creating a line chart with index data, use the IndexedLineSeries, IndexedStackedLineSeries, or Indexed100PercentStackedLineSeries classes.

Date/Time

When creating a line chart with date/time data, use the DateTimeLineSeries, DateTimeStackedLineSeries, or DateTime100PercentStackedLineSeries classes.

Normal

Normal Line charts create lines based on the data. They use DateTimeXAxis or IndexedXAxis as the XAxis based on the series and NumericYAxis as the YAxis.

Indexed

The following example illustrates creating a line chart with indexed data. As the example illustrates, to create the line series your perform the following steps.

• Create an IndexedLineSeries instance
• Add the values to the series instance using the Add method.
• Repeat for as many data series as relevant.
• Add all the line series instances to the plot area.
• Add the y-axis title.
• Add the x-axis labels for each series.

Date/Time

The following example illustrates adding a date/time series to a line chart. Perform the following steps to create the date/time chart.

• Create the needed DateTime instances.
• Create a DateTimeLineSeries instance to hold the data.
• Add the values, where each value is associated with the relevant DateTime instance.
• Repeat for as many line series instances as needed.
• Add each created line series to the plot area.
• Specify the y-axis title.
• Specify the x-axis date/time format.

100% Stacked

100% stacked charts are similar to stacked charts but the data is expressed as a percentage. These charts use the DateTimeXAxis or IndexedXAxis as the XAxis based on the series and PercentageYAxis as the YAxis.

Indexed

The following example illustrates adding 100% stacked indexed data to a chart. Perform the following steps to create the chart.

• Create a new Indexed100PercentStackedLineSeriesElement instance.
• Add the data to the instance.
• Repeat for as many instances as needed.
• Create an Indexed100PercentStackedLineSeries instance.
• Add the element instances to the series.
• Add the series to the plot area.
• Create the y-axis title.
• Add the x-axis labels as IndexedXAxisLabel instances.
