Custom image as PointMark

[Erik ter Beeke]

Hi there,

I am using the RadChart control in the context of a SharePoint 2010 site. I have a requirement to show a triangle at each point of a line series.
Since I didn't find a triangle in the default figures for the RadChart, I'm trying to display a custom image at each point.
I have tried this in a stand-alone ASP.NET web application and it works. I'm now trying to do the same in SharePoint, but I can't figure out how to specify the image url.

My current code looks like this:

<telerik:ChartSeries Name="My Series" Type="Line" ActiveRegionToolTip="#Y">
    <Appearance ShowLabels="False">
        <PointMark Visible="True" Dimensions-Height="20px" Dimensions-Width="20px" Dimensions-AutoSize="False" Figure="Rectangle">
            <FillStyle FillType="Image">
                <FillSettings BackgroundImage="/_layouts/img/triangle.gif">
                </FillSettings>
            </FillStyle>
        </PointMark>
    </Appearance>
</telerik:ChartSeries>

The line series is rendered, but no shape whatsoever is rendered at each point of the line series.

What am I doing wrong here?

Kind regards,
Erik ter Beeke

Hi Erik,

Please, specify the image location as relative to the web application root:

<FillSettings BackgroundImage="~/_layouts/img/triangle.gif">
</FillSettings>

I see several related tickets, but nothing exactly the same as mine....

We have this working

highStackedBarSeries.Appearance.PointMark.Fill =

 

new SolidColorBrush(Colors.Red);

 

 

highStackedBarSeries.Appearance.PointMark.Shape =

 

MarkerShape.Hexagon;

and we are able to work custom images in as well...  our challenge....   we want to make different decisions per point... some points are high, some are low, some are in valid ranges... we want to use the PointMark to show this by changing out the shape / color / iconset ....   one line, several points, change PointMark on the fly within a single lineseries. ?

Thanks, -James

Hi James,

The ChartSeriesItem has a property PointAppearance, you can use it to customize separate items:

RadChart1.Series[0][1].PointAppearance.FillStyle.FillType = FillType.Solid;
RadChart1.Series[0][1].PointAppearance.FillStyle.MainColor = Color.Green;
