question 1

i creating multiple line chart series in chart. winrt xaml toolkit assigns color each series in random manner. using custom style data points, when use custom style randomness of color goes off. how can set or random color of series ? if can color can use color in datapoint, , if can set color generate random color myself.

question 2

moreover while hovering on data points tool tip shows dependent value, want show more details how can achieve ?

here's code custom style.

<charting:chart x:name="linechart" title="line chart" margin="70,0">     <charting:lineseries                 title="population 1"                 independentvaluebinding="{binding name}"                 dependentvaluebinding="{binding value}"                 isselectionenabled="true">             <charting:lineseries.datapointstyle>                 <style targettype="charting:linedatapoint">                     <setter property="width" value="17" />                     <setter property="height" value="17" />                     <setter property="template">                         <setter.value>                             <controltemplate targettype="charting:linedatapoint">                                 <ellipse fill="green" stroke="green" strokethickness="3" />                             </controltemplate>                         </setter.value>                     </setter>                 </style>             </charting:lineseries.datapointstyle>         </charting:lineseries>      <charting:lineseries             title="population 2"             independentvaluebinding="{binding name}"             dependentvaluebinding="{binding value}"             isselectionenabled="true" foreground="blue">         <charting:lineseries.datapointstyle>             <style targettype="charting:linedatapoint">                 <setter property="width" value="17" />                 <setter property="height" value="17" />                 <setter property="template">                     <setter.value>                         <controltemplate targettype="charting:linedatapoint">                             <ellipse fill="red" stroke="red" strokethickness="3" />                         </controltemplate>                     </setter.value>                 </setter>             </style>         </charting:lineseries.datapointstyle>     </charting:lineseries> </charting:chart> 

chart random color (no custom datapoint style)

chart no random color (with custom datapoint style) [you can see both line has yellow color]

trying bing silverlight toolkit chart custom line color yields potentially useful pages, this. should work same winrt xaml toolkit, customize silverlight-based templates - need customize winrt xaml toolkit-based ones can either try extract blend/visual studio designer or original templates source can grab codeplex.
