    Hi,

    Is there any work around for kendochart to plot with category axis prefix for min 9AM to 5PM, baseunit as seconds?
    It took more than half a minutes to render to chart.

    I am using multi pane. One pane for price and the other pane for volume.

    Please advise.

    Regards,

    Hi,

    If I did my calculations correctly this comes to around 30K points per series.
    Is the source data with seconds resolution? If not then we might be plotting a lot more points than strictly necessary.

    Have you considered using the stock chart widget with virtualization?

    Hi T. Tsonev ,

    I've change to stock chart with virtualization.
    How to actually prefix the chart from 9:00:00 to 17:00:00.
    Currently the chart fix the end axis up to my latest date of data. If i don't have data of 17:00:00, can i still want it to fix to that interval?

    Hello,

    You can fix the navigator interval using its categoryAxis settings:
    categoryAxis: {
      min: new Date("2014/01/01 09:00"),
      max: new Date("2014/01/01 17:00")
    }


    -- Live demo --

    I hope this helps.

    Hello Kenz,
    I'm trying to do something very similar. Were you able to do seconds granularity using the stock chart? How many data points are you sending to the chart at one time?

    Thanks,

    I am also having an issue with the chart speed with a baseunit of seconds. It is extremely slow, I have 600 points to chart however with seconds baseunit it either does not plot the data or takes a very long time. Change it to minutes and it charts fine.

    What can be done to improve the speed yet still retain seconds resolution?

    Hello,

    Let's keep the discussion focused in the support thread.
    The suggestions we have won't be relevant to the stock chart.
