    Dear Mikhail,
    do we have the option or experience to do following two tasks:
    1. automatic refresh the chart every 2s (adjustable)
    2. I can see we have database (.dat files) of “current data” “minute data” and “hourly data”, and the min setting of “minute data” is 30s. is it possible to store data every 1s and show in the chart every 1s ?

    thanks a lot. and looking forward your reply.

    Yes, perhaps. You must manually set the time in the configuration file and do not touch this parameter in the GUI.

    <Param name=“WriteMinPer” value=”60″ descr=”Период записи минутных срезов, с” />

    in ScadaServerSvcConfig.xml

    When you zoom in on the ChartPro you will see the values for each entry point.
    Memory will eat up a lot

    Hello,
    In addition to the above, configure Chart Pro by editing PlgChartPro.xml, and set the RefreshRate parameter. I suggest use Chart Pro in the rolling mode if you need to refresh it often. To do this, use Dashboard Plugin, or put a chart on a scheme usgin Extended Scheme components.

    Thanks to both of you. based on instruction from both of you, I got it work.

    Mikhail,
    would you please explain more on how to use the rolling mode, and how to put chart on scheme using extended scheme components. I already have the trial key for both dashboard and extended scheme components. I would like to see the advantage of this.

    Likely the device didn’t respond that periods of time.

    In the rolling mode, a period of the specified length is displayed on chart. For example, 30 last minutes.
    Using Scheme Editor, put a chart component on a scheme and set its properties as you need. Select fixed or rolling mode.
