Need Help in displaying Line Chart

Please consider the following code:

Parameters I have used :

<cfparam name="Form.startdate" default="#dateformat(now()-5, 'mm/dd/yyyy')#">
<cfparam name="Form.enddate" default="#dateformat(now()-1, 'mm/dd/yyyy')#">
<cfparam name="Form.selectdate" default="#dateformat(now(), 'mm/dd/yyyy')#">

The cfquery I'm using is as follows:

Information: MyDatabase = Name of the Database

Events = Column name with several different events(First,Second,Third etc).In this case I have just included FIRST.

Timestamp = Name of the column which contains date and time.

<cfquery datasource = "XX.XX.X.XX" name="qQuery">


SELECT Timestamp , Count(*) as COUNT
FROM MyDatabase WHERE Events = "FIRST"
AND Timestamp >= <cfqueryparam value="#form.startdate#" cfsqltype="cf_sql_date"> 
AND Timestamp <=  <cfqueryparam value="#dateAdd('d', 1, form.enddate)#" cfsqltype="cf_sql_date"> GROUP BY Timestamp;
</cfquery>

The above query is just displaying one dot in the line chart which is obvious because I have used there count clause with condition for Events = FIRST.

The way I'm displaying is as follows (Please consider the following code):

<cfform format="flash" preloader ="false">

<cfformgroup type="horizontal">
  <cfinput type="dateField" name="startdate" label="Start Date" width="100" value="#form.startdate#">
  <cfinput type="dateField" name="enddate" label="End Date" width="100" value="#Form.enddate#">
  <cfinput name="submitApply" type="submit" value = "Apply">
  <cfinput name="cancel" type="submit" value="Download CSV">

</cfformgroup>

<cfformitem type = "hrule" style="" ></cfformitem>
</cfform>

<cfchart format="flash" chartwidth="500" chartheight="500" scalefrom="0" scaleto="2500" showxgridlines="no"  >


        <cfchartseries type="line" itemColumn="Timestamp" valueColumn="COUNT"  query="qQuery">

        </cfchartseries>
</cfchart> 

Problem I'm getting facing:

Nothing is displayed on the web browser except cfform fields. :(

When I right click on it, it says Movie not loaded.

Please let me know if there are some questions I can answer.
