    I have a chart with a LineSeriesDefinition with the ShowPointMarks option turned off:

    <Controls1:RadChart.SeriesMappings>
                    <Charting:SeriesMapping LegendLabel="Volume">
                        <Charting:SeriesMapping.SeriesDefinition>
                            <Charting:LineSeriesDefinition ShowItemToolTips="True" ShowPointMarks="False" ShowItemLabels="False" ItemToolTipFormat="Date: #X{g}&#x0a;Volume: #Y{n0}" />
                        </Charting:SeriesMapping.SeriesDefinition>
                        <Charting:SeriesMapping.ItemMappings>
                            <Charting:ItemMapping DataPointMember="XValue" FieldName="DipDate" />
                            <Charting:ItemMapping DataPointMember="YValue" FieldName="Volume" />
                        </Charting:SeriesMapping.ItemMappings>
                    </Charting:SeriesMapping>
                </Controls1:RadChart.SeriesMappings>

    The problem is that you have to position your mouse very carefully to be able to see the tooltip for each data point on the graph, ie the mouse pointer has to be over the exact pixel to get the tooltip. Is there a way to be able to make these tooltip easier to view? For example, it would be good if the tooltip would show up of the mouse pointer was within 5 pixels of the data point.

    Thanks,

    Geoff

    Hello Geoff Hardy,

    You need to re-template your line series and make the width of the transparent stroke below them bigger. Please check the attached project and let me know if it is ok. Please, use the binaries from out latest internal build, because our developers fixed some important issues concerning the tooltips there.
