Due to the presence of null values, FlexChart creates gaps once it has plotted the data. The gaps present in the plotted data make data look inconsistent and incomplete.</p> <p>FlexChart allows you to deal with such inconsistencies by using the <a href="C1.WPF.FlexChart.4~C1.WPF.Chart.ChartOptions~InterpolateNulls.html">InterpolateNulls</a> property. You can set the <a href="C1.WPF.FlexChart.4~C1.WPF.Chart.ChartOptions~InterpolateNulls.html">InterpolateNulls</a> property, so that the chart automatically fills in gaps created by null values in data.</p> <div style="WIDTH: 100%"> <table class="hs-box"> <tbody> <tr> <td class="hs-box-icon" valign="top"><img src="images/hs-note.gif"></td> <td class="hs-box-content" valign="top">The <strong>InterpolateNulls</strong> property is applicable only for the Line Chart and the Area Chart.</td> </tr> </tbody> </table> </div> <p>Here is how you can set the InterpolateNulls property:</p> <div class="FilteredContentCS TabContainer TabContainerWidget" data-title="C#" data-itemid="CS"> <ul> <li><a href="#TabContent-073fa994-4f98-459a-8532-24c908233474">C#</a></li> </ul> <div id="TabContent-073fa994-4f98-459a-8532-24c908233474" class="FilteredContent code"> <pre> flexChart.Options.InterpolateNulls = <span style="COLOR: #0000ff">true</span>; </pre> </div> </div> <p> </p> <a name="seealsobookmark"></a> </div> <div id="FooterContent"> <p> </p><p> </p><hr style="height: 1px"><p> Copyright © <script type="text/javascript"> var theDate = new Date() document.write(theDate.getFullYear()) </script> GrapeCity, inc.
