Question
How do I add a label when a new point is added?
Answer
When using an IlvDefaultDataSet, you can add a point using the method addData(double x, double y, String label).
You also have two options depending on the type of label you want to set:
- If the labels are static or cannot be evaluated dynamically, you can use
setDataLabels(String[] labels)and set all labels at once. - If the labels can be computed at runtime, you can use the method
setDataLabel(int idx, String label)or override thegetDataLabel(int idx)method as follows:IlvDefaultDataSet dataSet = new IlvDefaultDataSet("Demo") {
public java.lang.String getDataLabel(int idx) {
if (idx > getDataCount()) {
return "Undefined";
}
return "NE(" + idx + ")=" + getYData(idx);
}
};
