Hi Nan,

There are several methods. One simple method is to simply use whatever you want to see
in the legend as the data set name.

For example, instead of using (in C#/Java):

layer.addDataSet(myData, myColor, myName);

you may use:

//modify the myName to become myName(... sum_of_values ...)
layer.addDataSet(myData, myColor, myName + "(" + ((new ArrayMath(myData)).sum()) +
")");


Another method is to put the sum of values of all data sets in a separate array, add them
as an extra field of the layer, and configure the legend entry to show the extra field. It is
like:

double[] sumOfDataSets = { (new ArrayMath(myData0)).sum(), (new
ArrayMath(myData1)).sum(), (new ArrayMath(myData2)).sum(), ..... };

layer.addExtraField(sumOfDataSets);
c.getLegend().setText("{dataSetName} ({dsField0})");



By default, ChartDirector will automatically add all data sets that have names to the
legend box. To avoid the 'Failure Rate' to get into the legend box, there are two
methods:

- Do not provide the "Failure Rate" name when adding the line (just use "")

or

- Use Layer.setLegendOrder, like:

//disable automatic legend entry for myLineLayer
myLineLayer.setLegendOrder(Chart.NoLegend);


To hide labels 1 (or below?), you would need to use custom data labels. For example (in
C#):

//an array of arrays containing all the data series
double[][] allData = {myData0, myData1, myData2, .....};

for (int i = 0; i < allData.Length; ++i)
{
   for (int j = 0; j < allData[i].Length; ++i)
   {
        //replace label with an empty space
        if (allData[i][j] < 1)
             layer.addCustomDataLabel(i, j, " ");
   }
}


Hope this can help.
