Question

when I placed the label inside the pie chart(Code in bold).  When i decrease the size of the page with the jChartFx  pie chart the label inside the chart gets pushed outside of the pie chart with pointers.  It seem after a certain size of the page where the jChartFx pie chart is on it pushes the label outside of the pie chart.   How can I make the label inside the pie chart stay inside the pie chart no matter what size the page with jChartFx pie chart is?

 

code:

@model ePortfolio.Models.WidgetViewModel
@using System.Web.Script.Serialization;

<div class="widget-head" style="display:block;overflow:no-content;height:10%;width:100%;">
    <div class="widget-title text-center" style="padding-top:10px;"><label>@Model.Widget.Title</label></div>
    <div id="id-refresh-@Model.Widget.Id" class="wdgbkg"> </div>
   
</div>

<div class="widget-body" style="display: inline-block;overflow: visible;height:100%;width:100%;">
    <div class="widget-content" id="ChartDiv" style="display: inline-block; overflow: visible;height:90%;width:100%;"></div>
</div>

<script type="text/javascript" language="javascript">
    var chart@(Model.Widget.Id);

    function LoadPieChart() {

        chart@(Model.Widget.Id) = new cfx.Chart();

        chart@(Model.Widget.Id).setGallery(cfx.Gallery.Pie);
        chart@(Model.Widget.Id).getAllSeries().getPointLabels().setVisible(true);

        var pieAttr = chart@(Model.Widget.Id).getAllSeries().getGalleryAttributes();
        
        pieAttr.setSliceSeparation(50);
        pieAttr.setLabelsInside(true);
        pieAttr.setExplodingMode(cfx.ExplodingMode.First);

        //chart@(Model.Widget.Id).getAllSeries().getPointLabels().setFormat("%l %p%%");
        chart@(Model.Widget.Id).getAllSeries().getPointLabels().setFormat("%p%%");

        var str = @Html.Raw(Json.Encode(ViewData["Asset Allocations Chart"]));

        chart@(Model.Widget.Id).getAxisY().getDataFormat().setDecimals(2);
        chart@(Model.Widget.Id).getView3D().setEnabled(true);        

        chart@(Model.Widget.Id).setDataSource(str);

        var data = chart@(Model.Widget.Id).getData();
        data.setSeries(1);
        data.setPoints(10);

        chart@(Model.Widget.Id).getToolTips().setEnabled(true);
        chart@(Model.Widget.Id).getToolTips().setAlignment("near");
        chart@(Model.Widget.Id).getToolTips().setFormat("%l%");

        chart@(Model.Widget.Id).getLegendBox().setVisible(false);
        @*chart@(Model.Widget.Id).getLegendBox().setWidth(175);
        chart@(Model.Widget.Id).getLegendBox().setDock(cfx.DockArea.Right);
        chart@(Model.Widget.Id).getLegendBox().setContentLayout(cfx.ContentLayout.Near);*@

        chart@(Model.Widget.Id).getPlotAreaMargin().setTop(0);
        chart@(Model.Widget.Id).getPlotAreaMargin().setBottom(0);
        chart@(Model.Widget.Id).getPlotAreaMargin().setRight(0);
        chart@(Model.Widget.Id).getPlotAreaMargin().setLeft(0);

        var divHolder = document.getElementById('ChartDiv');
        chart@(Model.Widget.Id).create(divHolder);
    }

    $(function() {
        LoadPieChart();
    });
    
    function ResizeChart()
    {
        if (chart@(Model.Widget.Id) != null)
            chart@(Model.Widget.Id).doUpdate(true);
    };

</script>
