When using an IlvLogarithmicAxisTransformer and setting the data range on an IlvAxis, this range is not taken into account

Question

When using an IlvLogarithmicAxisTransformer and setting the data range on an IlvAxis, this range is not taken into account, is it normal ?

Answer

For instance, if you set the data range 5-1500, using an IlvLogarithmicAxisTransformer with the default base (base 10), the range gets adjusted to 1-10000.

This is the expected behavior.
When using a logarithmic transformer, the range is taken into account, but is modified to be of the form [10^k, 10^m].

This is the way logarithmic axes are usually drawn.

However, if this behavior is not what you expect, you can use the following workaround:

chart.getXAxis().setTransformer(new IlvLogarithmicAxisTransformer() {
public boolean validateInterval(IlvDataInterval itv) {
boolean modified = false;
if (getLogBase() > 1) {
if (itv.min <= 0) {
itv.min = 1;
modified = true;
}
if (itv.max <= 0) {
itv.max = 1;
modified = true;
}
}
return modified;
}
}
);
