Schedule type LineChart with clients and unavailable start and end dates

Question

I have been working on trying to get something in flex which will display a list of clients and their unavailability start and end dates.   I have attempted the line chart and the HLOC chart but have not seen success.  I do have the H or V grids working fine.  But getting the data to display in a line graph based upon start date and end date has been my challenge.  any suggestions
Current Code:
    <s:Label x="0" y="5" text="Min Date" height="24" fontFamily="Times New Roman" verticalAlign="middle"/>
    <mx:DateField id="minDateField"
                  x="50" y="5"
                  formatString="MM-DD-YYYY"
                  selectedDate="{minDate}"
                  change="minDatefield_changeHandler(event)"/>
    <s:Label x="150"  y="5" text="Max Date" height="24" fontFamily="Times New Roman" verticalAlign="middle"/>
    <mx:DateField id="maxDateField"
                  x="200" y="5"
                  formatString="MM-DD-YYYY"
                  selectedDate="{maxDate}"
                  change="maxDatefield_changeHandler(event)"/>
    <mx:LineChart id="nonAvailsLC" x="0" y="40"
                  showDataTips="true"
                  dataProvider="{getNonAvailsResult.lastResult}"
                  creationComplete="nonAvailsLC_creationCompleteHandler(event)"
                  width="890" height="550">
        <mx:backgroundElements>
            <mx:GridLines gridDirection="both"/>
        </mx:backgroundElements>
        <mx:horizontalAxis>
            <mx:DateTimeAxis dataUnits="days" minimum="{minDate}" maximum="{maxDate}"
                             labelUnits="days"/>
        </mx:horizontalAxis>       
        <mx:verticalAxis>
            <mx:CategoryAxis categoryField="user" labelFunction="getName"/>
        </mx:verticalAxis>       
        <mx:series>
            <mx:LineSeries xField="startDate" yField="user"
                           form="horizontal"/>
        </mx:series>
    </mx:LineChart>

Answer 1

I guess I still have lots to learn about Flex and Renderers. I downloaded a Gantt chart with Code and they used the AdvancedDataGrid with renderers and such.  I modified the code to work for me. but if I had to create it myself right now, I would be in trouble.  Lots more to learn.
