DataChart not Displaying Data Points
posted

Hello,

I am wanting to plot simple sales quantity by week which I have done with the window forms chart controls.
I am now wanting to do this with the web controls. My VS project is an ASP.NET MVC using Razor project.

Y Axis is Quantity
X Axis is Week
Would Like to display the event name and product name in the chart some how.


I have copied off some of the examples from the website but my data will not plot on the chart. I am providing a screen capture of current output and also the data and code. Would appreciate any help. Thanks!

Existing Code including commented out code

                @(Html.Infragistics().DataChart<eMerchantSystem.Orders.Reports.Models.OrderWeeklySale>()
                        .ID("uicEvents")
                        .Width("100%")
                        .AlignsGridLinesToPixels(true)
                        .Height("400px")
                        .Width("800px")
                        .VerticalZoomable(true)
                        .HorizontalZoomable(true)
                        .Legend(legend => legend.ID("legend"))
                        .OverviewPlusDetailPaneVisibility(Visibility.Collapsed)
                        .Title("Weekley Sales")

                        .Axes(axis =>
                        {
                            axis.CategoryX("Week").Label(item => item.Week).LabelLocation(AxisLabelsLocation.OutsideBottom).Interval(1).LabelLocation(AxisLabelsLocation.OutsideBottom).MinorStrokeThickness(1);
                            axis.NumericY("Quantity").MinimumValue(0).MaximumValue(500).LabelLocation(AxisLabelsLocation.OutsideLeft);
                            //axis.NumericY("TotalLoans").MinimumValue(0).MaximumValue(100).StrokeThickness(10).LabelLocation(AxisLabelsLocation.OutsideRight);

                            axis.CategoryX("xAxis").Title("Week").Label(item => item.Week);
                            axis.NumericY("yAxis").Title("Quantity").Label(item => item.Quantity);
                        })

                        //.Series(series =>
                        //{
                        //    series.Column("Sum").Title("Sales").Brush("#87AB3D").ShowTooltip(true).TooltipTemplate("Sum")
                        //    .XAxis("Week").YAxis("Quantity").ValueMemberPath(item => item.Quantity)
                        //    .Legend(legend => legend.ID("legend")).ShowTooltip(true).TooltipTemplate("Total Sales by Week").ShowTooltip(true);

                        //    //series.Spline("total").Title("Total Sales")
                        //    //.XAxis("MonthName").YAxis("TotalLoans").Thickness(3).ValueMemberPath(item => item.Total)
                        //    //.Legend(legend => legend.ID("legend2")).ShowTooltip(true).TooltipTemplate("Number of Loans");

                        //})

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

                            //series.Line("series2")
                            //.ValueMemberPath(item => item.ItemTotal)
                            //.Title("Upper Limit")
                            //.XAxis("xAxis")
                            //.YAxis("yAxis")
                            //.ShowTooltip(false);
                        })

                        .DataBind()
                        .Render()
                )

    Hello Richard,

    Thank you for posting in our community.

    If I understand correctly, your requirement is to be able to display the values of more than one property of a record. Please correct me if I am wrong. Otherwise, what I would suggest you is to use the Tooltip template feature, which will enable you to display all the properties of a record, using the jQuery templating syntax:

    <script id="tooltipTemplate" type="text/x-jquery-tmpl">
      <div style="color: #44ACD6">
          <span>Event: </span><span style="font-weight: bold">${item.EventName}</span><br />
          <span>Product:</span> <span style="font-weight: bold">${item.ProductName}</span><br />
          <span>Quantity</span>: <span style="font-weight: bold">${item.Quantity}</span>
      </div>
    </script>
    
    @(Html.Infragistics().DataChart(Model.Products.AsQueryable())
    ...
    .Series(series =>
    {
        series.Line("series1")
        .ValueMemberPath(item => item.Quantity)
        .Title("Quantity")
        .XAxis("xAxis")
        .YAxis("yAxis")
        .ShowTooltip(true)
        .TooltipTemplate("tooltipTemplate);
    ...
    .DataBind()
    .Render()

    Attached you will find an example that I have prepared in order to demonstrate how to use this feature. Please test it on your side and let me know whether you find it helpful.

    Additionally, I believe you will find the following documentation regarding how to use the Tooltip feature very helpful.

    - Tooltips section of igDataChart overview topic

    - The Series Tooltips example

    Please do not hesitate to contact me if you need any further assistance with this matter.
