    I cannot seem to get an X Axis to behave as a non-categorical type of axis. In other words, not only do we have numerical data in the Y-Axis, but also we've got numerical data in the X-Axis. Is this possible with Telerik RadChartView? Or does the X Axis always get treated like a "category"? If so, how?

    Thank you...

    Hello Michael,

    I believe this is case is covered in the demos application, could you please take a look at that one, under ChartView -> Drill-down, and drill down to the most explicit chart there there are numerical values for both X an Y values.

    Please let me know if I've misunderstood the question

    DateTimeContinuousAxis horizontalAxis = new DateTimeContinuousAxis();
    horizontalAxis.MajorStepUnit = Charting.TimeInterval.Year;
    horizontalAxis.MajorStep = 1;
    horizontalAxis.LabelFormat = "{0:yyyy}";
    horizontalAxis.Title = "Year";

    Starting from this snippet of code, close but not quite. We're not working with DateTime, per se. We are working with TimeSpan, or possibly floats/doubles if we expose TotalSeconds, TotalMilliseconds, etc.

    Hi Michael,

    Thank you for writing.

    From what I understand you want a series which has two numerical dimensions along the two axes. If this is correct then you can have a look at the ScatterSeries and the ScatterLineSeries. They work with two numerical axes. 

    I hope this will be useful. Should you have further questions.
