I have a line chart, in which I want to print an arbitary text as the
label of the datapoint. The text I want to print will be determined from
the orthogonal value of the data point. Any pointers on how to achieve
this?

Thanx.

Anup,

Try something like this:

function beforeDrawDataPointLabel(dph, label, icsc)
{
myval = dph.getOrthogonalValue();
mylab = label.getCaption().setValue("datapoint "+myval);
}

Thanks. Works like a charm. But this has led me to another scenario. To
draw my line chart, I am pulling data from a database table essentially
having four fileds:
1. GUID : contains a unique row identifier
2. X Axis value : contains the base values of the line chart
3. Y Axis value: contains the orthogonal values of the line chart
4. Some Text : contains some additional text

Now for drawing the line chart, I am creating two arraylists representing
the "X axis value" (String) and the "Y Axis value" (Double) and setting
these as the dataset for the two series (base and orthogonal
respectively). till this step every thing works fine. Now my problem is I
want to print the text in the "Some Text" field as the datapoint label for
each datapoint. How ever I am not able to do this as there is no reference
to the "GUID" field in the orthogonal dataset and hence I cannot retrieve
the corresponding "Some Text" value.

Any pointers? Thanks.

Anup,

I do not know of a way to do this. If your array list is available, may
be you can call out to it from the script to get the text value.
