But you can use the  dataFunction property to set a function that does 
calculations on the fly.

yField is just a reference to a property or node in your dataset... in your 
case "uptime"... if you want to do a calculation, you will have to perform that 
on your dataset prior to plotting in the ColumnChart. .. you can't perform a 
calculation on the field reference as you're trying to do.

Hi All,
I am using Column chart in my project. Here i need to plot uptime and downtime 
of the system using column chart. Uptime data will come from the database like 
this:
    <StatusGraph>
        <data>
          <date>10</date>
          <uptime>0</uptime>
        </data>
        <data>
          <date>11</date>
          <uptime>1</uptime>
        </data>
        <data>
          <date>12</date>
          <uptime>2</uptime>
        </data>
        <data>
          <date>07</date>
          <uptime>2</uptime>
        </data>
        <data>
          <date>07</date>
          <uptime>2</uptime>
        </data>
        <data>
          <date>18</date>
          <uptime>0</uptime>
        </data>
      </StatusGraph>
 I am not getting any downtime information from the database. Doubt i have here 
is can i do any calculations before plotting the graph.
 I tried like this. But its not working.
                <mx:ColumnChart id="chart" dataProvider="{resultXML.System[ 
0].StatusGraph. data}"                 type="100%" width="500" height="250" 
showDataTips="true">
                    <mx:series>
                        <mx:ColumnSeries yField="uptime" />
                       <mx:ColumnSeries yField="100-uptime" /> -- Doubt
                    </mx:series>
                    <mx:horizontalAxis>
                        <mx:CategoryAxis categoryField="date" />
                    </mx:horizontalAxis>
                </mx:ColumnChart>
SO here iam using yfield as 100-uptime to calculate downtime. But its not 
displaying any data. Can any one help me regarding this.

Thanks and Regards,
Poornima
