    Team, I am using the time bar to visualize some data but for some reason, the data points do not line up.
    My data looks like
    rundte             overallVulnCount   overallVulnRemediated gap
    2012-02-06 00:00:00 81577       16370                                           65207
    2012-02-07 00:00:00 86131      22833                                           63298
    2012-02-08 00:00:00 86131      22833                        63298
    2012-02-09 00:00:00 86131   22833   63298
    2012-02-10 00:00:00 86131   22833   63298
    2012-02-11 00:00:00 86131   22833   63298
    2012-02-12 00:00:00 86131   22833   63298
    2012-02-13 00:00:00 86131   22833   63298

    but when I link the data, I have data points showing up in january of 2012. and when I compress the timebar, those dates do not go away.

    here is my binding, class and code.
    DateTime nudte = (DateTime)item.rundte;
                    trenditems nutrnd = new trenditems();
                    if (nudte < startDate)
                        startDate = nudte.AddDays(-7);
                    int totalvulncount = (int)item.overallVulnCount;
                    int totalremcount = (int)item.overallVulnRemediated;
                    nutrnd.itemdte = nudte;
                    nutrnd.remainingcnt = totalremcount;
                    nutrnd.overallcount = totalvulncount;
                    nutrnd.gapcount = (int);
                    if (totalremcount > totalvulncount)
                        bool itemfail = true;
                    totalvuln.Add(nudte, totalvulncount);
                    totalremediated.Add(nudte, totalremcount);
                timeSelector.PeriodStart = startDate.AddMonths(-2);
                timeSelector.PeriodEnd = endDate;
                timeSelector.VisiblePeriodStart = endDate.AddMonths(-1);
                timeSelector.VisiblePeriodEnd = endDate;
                timeSelector.SelectionStart = endDate.AddDays(-14);
                timeSelector.SelectionEnd = endDate;
                timeSelectSpark.XValuePath = "itemdte";
                timeSelectSpark.YValuePath = "gapcount";
                timeSelectSpark.ItemsSource = trndlist;

    Here is the data class I am using
    public class trenditems
        public DateTime itemdte { get; set; }
        public int overallcount { get; set; }
        public int remainingcnt { get; set; }
        public int gapcount { get; set; }
        public trenditems()

    And here is the xaml
    <telerik:RadTimeBar Grid.Row="0"
                               <telerik:MonthInterval />
                               <telerik:WeekInterval />
                               <telerik:DayInterval />
                               <telerik:RadLinearSparkline Name="timeSelectSpark"
                                                           AutoRange="False" />

    Hi Patrick,

    RadTimeBar is a content control and currently it doesn't know much about its content. That's why when you have a sparkline it is up to you to match the data that the sparkline shows with the period the timebar shows. You can try setting manual range on your sparkline. This way the sparkline will use your range on the X-axis and the gap will be displayed. Manual range is set first by disabling AutoRange and then by setting these properties: MinXValueMaxXValueMinYValueMaxYValue

    Hi Yavor,

    Could you provide me with an example on how you manually set the range on a sparkline?
    The properties MinXValueMaxXValueMinYValueMaxYValue got me puzzled.
    I can't get my sparklines to appear.

    Hello Ben,

    I have created for you a small demo application that shows how you can use these properties. Each one of them is auxiliary, so if you want to configure the range on the X you don't need to specify range for the Y.

    If you have more questions don't hesitate to contact us!
