    Hi,
    I need to create a chart similar to the image attached. My main question is whether this can be done using ChartView and if yes, then how to do this. The main point of the chart is to display a combination of events and individual point. Each point has a timestamp and a value, and an event has a start time and end time. The X axis is time. The Y axis is a type (a string description). The ChartView control is quite extensive, and I used it in the past to display scatter graph, but this problem has me puzzled. Displaying individual point streams is easy, but the event stream part does not seem to fit into anything available to me. Based on my reading it seems as I may have to implement my own series class - if that is the case the example of doing so would be great.

    Thanks

    Hello Eric,

    Yes, you are correct, we do not have a range bar series for RadChartView yet. We will add support for this type of series for the next official release, scheduled for October. 

    However, I would like to point out that in case you have date time x-axis and categorical y-axis, you would not be able to display the line series as in the attached picture. Basically, you need a linear y-axis so that the data points have correct position according to the y-axis. The labels that you want to show seem more like a legend in this case.

    You can take a look at our RadTimeline and RadGanttView controls, in case one of these controls better suits your needs:
