Histogram Control
Add a New Series
This page describes how to add a histogram series. The histogram control of the .Net Analytics package is of the following type:
The series class of the histogram chart is:
The first step is to include the necessary namespaces
for the controls.
Add a Single Series
Below, we will add a new series to a Histogram chart (named hcChart in the
examples below):
[Visual Basic]
' Create a new series
Dim hsSeries As New HistogramSeries("Series 1")
' Add the series to the collection
hcChart.SeriesCollection.Add(hsSeries)
' An alternative is to add the series directly to the collection
hcChart.SeriesCollection.Add("Series 1")
[Visual C#]
// Create a new series
HistogramSeries hsSeries = new HistogramSeries("Series 1");
// Add the series to the collection
hcChart.SeriesCollection.Add(hsSeries);
// An alternative is to add the series directly to the collection
hcChart.SeriesCollection.Add("Series 1");
After the series has been added, samples may then be added to the
series. Adding samples is discussed here. The first series of the chart can be referenced via hcChart.SeriesCollection[0]. The resulting
chart should look similar to the following:
Add More than One Series
The histogram control supports multiple series. Just add more series to the series collection.
[Visual Basic]
' Create a new series
hsSeries = New HistogramSeries("Series 2")
' Add the series to the collection
hcChart.SeriesCollection.Add(hsSeries)
' An alternative is to add the series directly to the collection
hcChart.SeriesCollection.Add("Series 2")
[Visual C#]
// Create a new series
hsSeries = new HistogramSeries("Series 2");
// Add the series to the collection
hcChart.SeriesCollection.Add(hsSeries);
// An alternative is to add the series directly to the collection
hcChart.SeriesCollection.Add("Series 2");
The nth series of the chart can be referenced via hcChart.SeriesCollection[n]. The resulting
chart from above should look similar to the chart on the left after data has been added to the series. The chart
on the right has the first series hidden:
