Strip chart what is the recomended method.
Posted: Thu Jan 03, 2008 6:00 am
I'm using version TeeChart6 and VB2008. This code is sufficient to to display a strip chart using components with default settings but I would prefer to have code that is optimized for speed as well.
Is there a setting I should be using to automatically adjust the minimum value of the bottom axis. Is there a more appropriate method to do a strip chart?
End result I expect to display 8 analog values in real time. The faster I can get the screen to update the better. I would like to show the graph at about 1500x1000 resolution.
Code: Select all
Public x, y As Double
Private Sub frmStripChart_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
AxTChart1.AddSeries(TeeChart.ESeriesClass.scLine)
AxTChart1.Aspect.View3D = False
AxTChart1.Axis.Bottom.Automatic = False
AxTChart1.Axis.Bottom.AutomaticMaximum = True
AxTChart1.Legend.Visible = False
y = 0
x = 0
Timer1.Enabled = True
Timer1.Interval = 20
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim z As Double
y = y + 0.05
x = x + 1
z = Math.Sin(y)
AxTChart1.Series(0).Add(z, "", RGB(215, 0, 0))
AxTChart1.Axis.Bottom.Minimum = x - 1900
End Sub
End result I expect to display 8 analog values in real time. The faster I can get the screen to update the better. I would like to show the graph at about 1500x1000 resolution.
