ChartBySampling over flow?

[Taka_Y]

Hello,
ChartBySampling seems to overflow after several hours.　see attached file.
Is there a solution by setting change?

Best regards,
Taka

Are you using PLCAddressYAxisMin ? I did see this one time before when I was using PLCAddressYAxisMin. I will have to find that application to see what was done to fix it. Are you using version 3.99x?

Hi Archie,
Thank you for your support!
I did not use PLCAddressYAxisMin on v3.99x.
I sent error log txt for you send by e-mail.
Thank you!

Based on this:

I would say to try adding this line of code in the form load event handler. With the form open in designer, double click in a blank area to get to the event, then enter this code:

Chart1.AlignDataPointsByAxisLabel()

Replacing Chart1 with the name of your chart (possibly ChartBySampling1)

Hi Archie,
Thank you for your support.
The problem solved.
By the way, Can I set it up sample rate without ComComponent?
