    Default CCC Line chart doesn't get new data after refreshing

    Hi everyone,


    I am using pentaho cde to create a real-time dashboard.
    My dashboard has a CCC line chart.
    My data source of the dashboard is a Kettle transformation which have a Apache Kafka Consumer step to read message from broker, do some more process...
    I set the Refresh Period properties of the CCC line chart to 5.
    It really do refresh every 5 seconds.
    But my problem is that the line chart doesn't get new data to draw.
    Could anyone please help me to solve this problem.
    Sorry for my bad english.


    Many thanks,
    Hoang Anh.

    Are you sure you're getting new data from the transformation?

    Do you see change in the data returned if you inspect the doQuery call in the browser console?

    Hi pamval,


    Thanks for your reply.
    I can run the transformation in Pentaho Data Integration and it can get new data from broker.
    But I don't know how to doQuery call in the browse console for checking as you said.
    Can you please guide me how to doQuery call in the browser console?


    Many Thanks in advance,
    Hoang Anh.

    Open the developer tools in the browser.
    Run the dashboard.
    If you go to the network console tab, you'll see the calls to doQuery. If you inspect those, you can see what data is returned.
