Dynamic graph in vb.net

Question

Hello everyone,

i am to generate a line graph in vb.net. The graph should be something dynamic. I have a program calculating total distance, therefore in my output window i have iteration number and its corresponding value.

I have to plot the graph as iteration number by iteration value.

I have tried an offline graph where i saved the values of the iterations and then draw the graph with the values.

But this is not what i am actually suppose to do. The graph should be generated simultaneously as the processing is being done.

I am finding this a bit tough to do. Can someone please guide me?

Thanks.

Answer 1

can you show the code you have so far? and what else you've tried

you probably just want to use the Points.AddXY method

Imports Infragistics.UltraChart.Shared.Styles
Imports Infragistics.UltraChart.Resources.Appearance
Imports Infragistics.UltraChart.Core.Layers
Public Class Graph


    Private Sub Graph_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.UltraChart1.ChartType = ChartType.LineChart
        Dim myChartArea As New ChartArea()
        Me.UltraChart1.CompositeChart.ChartAreas.Add(myChartArea)
        ' Add the first series to the Line Chart
        Dim numseries As NumericSeries = GetNumericSeries()
        UltraChart1.LineChart.ChartComponent.Series.Add(numseries)
    End Sub
    Private Shared Function GetNumericSeries() As NumericSeries
        Dim series As New NumericSeries()
        ' This code populates the series using unbound data
        series.Points.Add(New NumericDataPoint(5, "Point A", False))
        series.Points.Add(New NumericDataPoint(4, "Point B", False))
        series.Points.Add(New NumericDataPoint(3, "Point C", False))
        series.Points.Add(New NumericDataPoint(2, "Point D", False))
        series.Points.Add(New NumericDataPoint(1, "Point E", False))
        Return series
    End Function

End Class

this is simply plotting the graph by the values im providing it.
what it's actually suppose to do..is to take the values by itself while the distance is being calculated in another form.

Hi Nirvana,

According to the codes in your post, it seems that you’re using a 3-rd party control and I’m not able to compile those codes right now.

As for “to take the values by itself while the distance is being calculated in another form”, you could call graph form after the calculation finished in another form. And pass parameters (such as property) to graph form.

If I misunderstood anything, please feel free and let me know.

Best regards,
