  samplesize value for make X-axis to 72 hours
Posted by Cici on Mar-23-2018 04:09

I am using VB.NET to program a real time running chart.
Currently, I can get charts for X-axis which value is 12/24 hours.

Code is as following:
12 hours:
    Private Const sampleSize As Integer = 14400
    chartUpdateTimer.Interval = 5000

24 hours:
   Private Const sampleSize As Integer = 28800
   chartUpdateTimer.Interval = 5000


Now, I want to get the 72 hours in X-axis. When I change the sampleSize to 86400, the WinChartViewer is blank. Nothing comes out.

Do you have any solution for my problem?

Thanks,

Cici

Never mind, already found the solution.
Need to multiple the dataRateTimer.Interval
