Statistical Box Plot !

[nguyenquocbo]

Dear all

I see a example in resoucre center as bellow :

chart1.Data.Series = 4

chart1.Data.Points = 30

' Create the Statistics extension

' If the extension is created at design-time you don't need to create it here

Dim statistics1 As Statistical.Statistics

statistics1 = New Statistical.Statistics

statistics1.Chart = chart1

chart1.LegendBox.Visible = false

' Set the gallery to Box Plot

chart1.GalleryAttributes = statistics1.Gallery.BoxPlot 

 

 Now, i try code as bellow :

            Dim dt As DataTable = Get data from a table in sql

            Dim chartFX As New ChartFX.WebForms.Chart

            chartFX.Data.Series = 10

            chartFX.DataSource = dt

            Dim statistics1 As Statistical.Statistics

            statistics1 = New Statistical.Statistics

            statistics1.Gallery.BoxPlot.Notched = False

            statistics1.Chart = chartFX

            chartFX.LegendBox.Visible = False

            chartFX.GalleryAttributes = statistics1.Gallery.BoxPlot 

 But i can't monitor data by Box Plot because unsuccessful !

Pls, help me, how to set datasource for Box Plot graph from database

Thanks !

What do you mean by unsuccessful? What do you get if you plot lines instead of box plot for the same data?

Dir sir

if i set : chartFX.DataSource = dt then chartFX return for me a message "No data available"

But my datatable have 4000 record !

and after that i try remove line : chartFX.DataSource = dt

and replace by new line : chart1.Data.Points = 30 ==>OK

So i can not set datasource for chartFX when set type is  Box Plot

Pls help me !
