If you want to plot your live data together the data from archiver, you can use data browser.

You can drag the PV into data browser, and tell data browser how many history data you want to retrieve from archiver.

It plots all you wanted archived data, then continuously add your live data together with it.

 

Thanks,

主题： Question about values of historic PVs dislpayed in CSS XY Graph widget

Hi, 

    I use the pre-configured for the SNS Office version of CSS (sns-css-4.1.1), and I intend to plot the values of live PVs and historic PVs in XY Graph widget. 

    I have tried drag the pv name on the XY graph widget and only the values of live PVs could display, and when refreshing the widget all the values are cleared.

    I want to consult you that how the XY graph widget achieve the same functions as that of Data Browser widget. The funcitons include getting the values of historic data by random time intervals from mysql and display the raw data or optimised data and so on.

    Any help will be appreciated and thanks in advance.
