igniteui ASP.NET MVC Helper not showing tooltip correctly
posted

Hi,

we are using the igniteui ASP.NET MVC Helper for showing a DataChart in our View and it everything worked great until we were trying to mark the maximum point in the line series with a red dot. After looking at the examples from this thread: www.infragistics.com/.../90010.aspx we modified our view like this:

<div style="height: 400px">
        @(Html.Infragistics().DataChart(Model.AsQueryable())
              .ID("chart")
              .Width("600px")
              .Height("400px")
              .VerticalZoomable(true)
              .HorizontalZoomable(true)
              .Title("Timeline")
              .OverviewPlusDetailPaneVisibility(Visibility.Visible)
              .Axes(axes =>
              {
                  axes.CategoryX("xAxis")
                      .Label(item => item.Time);
                  axes.NumericY("yAxis")
                      .Title("mm/s");
              })

                      .Series(series =>
                          {
                              series.Line("series1")
                              .ValueMemberPath(item => item.Value)
                              .Title("X")
                              .XAxis("xAxis").YAxis("yAxis")
                              .ShowTooltip(true);

                              series.Line("maximum")
                              .ValueMemberPath(item => item.Maximum)
                              .Title("X")
                              .XAxis("xAxis").YAxis("yAxis")
                              .ShowTooltip(true)
                              .MarkerType(MarkerType.Circle)
                              .MarkerBrush("rgba(255, 0, 0, 255");
                            })
              .DataBind()
              .Render())
    </div>

If we run it this is what we get:

As you can see the tooltip box doesn't show the value on the y-axis which we need! Only after zooming about 10 or more steps we get the complete info in the box:

Does anyone know whats the problem here? If there is another way to get the single point marker this would also be ok. Please advise.

Thank you
