Missing Line Segment in Contiguous Line Chart Data

Hello!

I have a line chart with 5 series' and 4 data points for each series.  For some reason, there is a missing line segment from the first data point (in all series') to the second.  See attached screenshot for the problem.

Any thoughts as to why this is occurring?

The chart is defined as:

                <ej:Chart ID="chrtActualsByCategoryLine" runat="server" Text="" Width="900" Height="400" CanResize="true" OnClientLoad="loadTheme" >
                    <PrimaryXAxis Title-Text="Date" />
                    <PrimaryYAxis LabelFormat="{value}" RangePadding="Round" Title-Text="Hours"/>
                    <CommonSeriesOptions Type="Line" /><Series/>
                    <Legend Visible="true"></Legend>
                </ej:Chart>
               

The datasource XML is:

<?xml version='1.0' encoding='utf-8' ?>
<chartxml>
    <data date='02/23' value1='0' value2='0' value3='0' value4='0' value5='0' />
    <data date='03/02' value1='0' value2='0' value3='0' value4='0' value5='0' />
    <data date='03/09' value1='0' value2='0' value3='0' value4='0' value5='0' />
    <data date='03/16' value1='2.00' value2='5.30' value3='2.00' value4='2.00' value5='6.80' />
</chartxml>


And the datasource is being loaded with:

                System.Data.DataSet data = new System.Data.DataSet();
                data.ReadXml(new System.IO.StringReader( "XML DATA GOES HERE" ));
                objChart.DataSource = data;
                objChart.DataBind();

Thank you for the quick response!

The scripts we are using indicate version: 12.2.0.36
The ddls we are using indicate version: 12.2451.0.36

I double-checked the issue and it still occurs even in a streamlined version.  Here are the steps to reproduce:

IN MARKUP
        <ej:Chart ID="Chart1" runat="server" >
            <PrimaryXAxis Title-Text="Date" />
            <PrimaryYAxis Title-Text="Hours"/>
            <CommonSeriesOptions Type="Line" /><Series/>
            <Legend Visible="true"></Legend>
        </ej:Chart>

We're referencing the following scripts:
    <link rel='nofollow' href="/Styles/ej.web.all.min.css" rel="stylesheet"/>
    <script src="/Scripts/jquery-1.10.2.min.js"></script>
    <script src="/Scripts/jquery.easing-1.3.min.js" type="text/javascript"></script>

            Chart1.CommonSeriesOptions.DoughnutSize = 0.2;
            Chart1.CommonSeriesOptions.Tooltip.Visible = true;
            Chart1.CommonSeriesOptions.Marker.Size.Height = 10;

Hi Mark,


We have analyzed the reported issue in your use case sample and we are able to reproduce the issue in 12.2 versions. But this issue is resolved in current 13.1 versions. So, can you please upgrade to the latest versions?

Please let us know if you need any clarification.

Thanks,

Praveenkumar


MW Mark Wise June 20, 2015 12:42 AM UTC

That worked like a charm, thanks!

However, I noticed that the "LabelFormat" property on the PrimayYAxis element no longer seems to allow for the formatting of currency values.

In the sample code below, if you change

 <PrimaryYAxis Title-Text="Hours"/>

to

 <PrimaryYAxis LabelFormat="c0" Title-Text="Dollars"/>

the value no longer formats as currency.  Has that feature changed, or been deprecated?   I need to be able to format data as:  "$#,000.00"

(We're now on version 13.1.0.21 of the libraries)

Regards,

Mark
