Hi,
On category chart, the width of the zoom rectangle is fixed at the chart width...
is it possible to have a zoom like on time chart : zoom of just a part of the x axes... ?
thank you, tatia34

No, because at present the CategoryAxis does not support any form of zooming - so the zoom function for the CategoryPlot only relates to the value axis.

I'd like to bump this for a bit more information. We are in a similar bind, we have a bar chart created using the ChartFactory.createBarChart() method. We typically have 8-10 categories, but as many as 50 data points in each category. This produces a dense chart, where the bars are only 2 or 3 pixels across, which makes it difficult to identify outliers. I'm thinking of writing my own mouse event listener to listen for changes in x coordinates and then re-draw the whole chart with a subset of the categories in the dataset, but that seems terribly inefficient. Is there any way to achieve this type of zooming with JFreeChart as it stands?
Thank you,
Todd
