c# - How to display the following result in WPF chart -

in wpf application, have following query display selected date range 'date' , total number of servers being processed on each day 'amount'.

  var query_1 =     (this.db.servers   .where(a => (a.date >= fromdp.selecteddate.value && a.date <= todp.selecteddate.value)    && ((a.serverid == "serverid1" || a.serverid == "serverid2") && a.type == "complete"))   .groupby(a => entityfunctions.truncatetime(a.date))   .orderby(a => a.key)   .select(g => new { date = g.key, amount = g.count() }))   .tolist(); 

which returns output following when bind listbox's itemssource ( check whether query works correctly)

now how bind result, date , amount wpf chart x , y axis. ( x- axis date , y-axis amount).

the chart can either bubble series/line series or column series.

this blogpost may have need.

http://www.itdevspace.com/2010/09/wpf-toolkit-datagrid-chart-example.html

basically place information retrieve linq query collection list have (the example in blog post above uses , observablecollection notification purposes) , chart itemsource property collection, independentvalue date, , dependentvalue amount.

<charting:lineseries     itemssource="{binding path=data}"     independentvaluebinding="{binding date}"     dependentvaluebinding="{binding amount}"/> 

i haven't tried on anonymous types may need change query logic more explicit. above xaml code expects datacontext have collection name data containing items properties date , amount.
