Re: How to adjust X = Y numberaxis scale

many thanks for this investigations .... yes of course youre completely right.... But have a louk at your XYShapeRendererDemo example. Is it really the expected behaviour that the shapes are shared when resizing the window, so each circle becomes an ellipse? I would name it "lockAxisRatio(domainAxis...

Re: How to adjust X = Y numberaxis scale

thanks, yes i already override the zoom method, thats nearly ok,
but as you say, i am searching for a not "dirty" solution adjusting the axis' factors.

Using JFreeCharts since 1997 i could not imagine that there is no option for that too.
;-)

best regards

How to adjust X = Y numberaxis scale

Hi David, im sorry, but can't figure out how to adjust x and y axis to have identical scale factors when resizing the window or zooming. What is the preferred method? For example in the XYShapeRendererDemo circle show always remain a cirlce and square should remain square. If you show real word geom...

RenderingHint in drawRangeLine() but notin drawRangeMarker()

Hi David, it seems to me that using RenderingHint in AbstractCategoryItemRenderer.drawRangeLine() causes my problem. A RangeMarker at y=0.0 and BasicStroke(0.5) and a GridLine at y=0.0 and BasicStroke(0.5) do not hide each other in all zoom status. So if zoom scrolling, sometimes both appear. Thats ...

DatasetUtilities.iterateDomainBounds() versus iterateDomainB

Hi David, autoScaling for IntervalXYDataset seams to have a bug, doesnt it? DatasetUtilities.iterateDomainBounds() takes all three values into consideration, but iterateToFindDomainBounds() doesnt. 1. Why those differences in two methods? 2. ok, if IntervalXYZDataset implies getStartXValue() must be...

Layer for selection of curve elements (selectionrectangles)

Hi David, please give some hints, what would be a prefered solution for showing multiple selections rectangles without having to redraw all the underlying series. There are up to 100 series in a plot with up to 100.000 items each. So if the selection rectangle is drawn in the series renderer, it is ...
