Time Series Controls

Axis Types

This page describes how to change the type of axis for a time series control. The axis type generally affects the sorting of the data in a series. The time series controls of the .Net Analytics package include the following:

Individuals (IndChart)
Moving Range (MovRngChart)
Moving Average (MovAvgChart)
Xbar (XbarChart)
Range (RangeChart)
Standard Deviation (StdDevChart)
RMS Deviation (RMSDevChart)

The series classes of the respective charts are:

The axis that supports multiple types (index, date, key, etc.) is the x-axis of the charts, which is of the following type:

HorizontalAxis

The property for indicating the type of x-axis is:

AxisLabelType

The x-axis types supported by the time series controls include:

Code: data are sorted by the code property of the samples and the code is shown on the x-axis
Date: data are sorted by the date/time of the samples and the date is shown on the x-axis
DateIndex: data are sorted by the date/time of the samples, the date is shown on the x-axis, and the points are evenly spaced
DateTime: data are sorted by the date/time of the samples and the date/time is shown on the x-axis
DateTimeIndex: data are sorted by the date/time of the samples, the date/time is shown on the x-axis, and the points are evenly spaced
Index: data are sorted by the order they are added to the series and the index is shown on the x-axis
Key: data are sorted by the key (string) property of the samples/subgroups and the key is shown on the x-axis
Time: data are sorted by the date/time of the samples and the time is shown on the x-axis
TimeIndex: data are sorted by the date/time of the samples, the time is shown on the x-axis, and the points are evenly spaced

Additionally, the following series property can be set such that data is always sorted by the order it is added to the series, but the axis can display dates, times, keys, etc.:

AlwaysSortByIndex

The first step is to include the necessary namespaces for the controls and add a new series.

Change the Axis Type

Below, we will change the axis type for an Individuals chart (named indChart in the examples below). The process is similar for the other charts:

[Visual Basic]

' Change the axis type to display dates and times

                  indChart.XAxis.AxisLabelType = HorizontalAxisLabels.DateTime

                  

                  ' Change the axis type to display keys

                  indChart.XAxis.AxisLabelType = HorizontalAxisLabels.Key

[Visual C#]

// Change the axis type to display dates and times

                  indChart.XAxis.AxisLabelType = HorizontalAxisLabels.DateTime;

                  

                  // Change the axis type to display keys

                  indChart.XAxis.AxisLabelType = HorizontalAxisLabels.Key;

After the series has been added, samples or subgroups may then be added to the series. Adding samples and subgroups is discussed here and here respectively. The resulting chart from changing the axis types should look similar to the following:
