Hello
I want to plot three different values of two different references i.e I want to plot current on
y axis, logtime on x-axis and the BAG value of a segment should be displayed on that
particular value of current and logtime. These values will be plotted of two different
reference ,the first one is the best refernce and I want to compare this refernce with the
actual live values.On the graph I want to show the difference of the BAG values of both the
references on a particular logtime and current value.
In this way I want to show my graph.Can I achieve this through ChartDirector???I think Bar
Graph will be best.If there is any other graph to represent what I want to show ,please tell
how and which one.

Hi Mikey,
Yes, ChartDirector can achieve you need. The exact chart type depends on the nature of
your data.
Sorry, I think I do not completely understand how your chart is created. Anyway, if you
would like to plot a stacked bar chart, or a overlay bar chart, and you want to display the
difference between two bar segments on top of the bars, you can use
addCustomAggregateLabel. For example, in Java, it is like:
BarLayer layer = c.addBarLayer2(Chart.Stack);
layer.addDataSet(dataArray1, color1, "ABC");
layer.addDataSet(dataArray2, color2, "DEF");
for (int i = 0; i < dataArray1.Length; ++i)
layer.addCustomAggregateLabel(i, "" + (dataArray1[i] - dataArray2[i]), "Arial Bold", 10,
0x000000);
To show detail data values and their differences on the chart, another method is to put
"data table" on the x-axis. For example, see"

Hope this can help.
