Re: TeeChart for Java very slow on Android

I had similar problems with performance on Android 2.3 and lower. It turned out the problem was not in TeeCharts but in SimpleDateFormat. Since dates are often used on charts, this might be the reason for TeeCharts to appear slow. It actually turned out that creating a new instance of SimpleDateForm...

Re: Monthly time step repeats some months

Thank you, that solved the problem.

Re: Monthly time step repeats some months

With this solution I am now facing a different problem: the custom labels are always displayed, they are not automatically hidden when they overlap.

Re: Monthly time step repeats some months

I tried your solution now, well, a version of it. It actually fixed the problem.

Re: Monthly time step repeats some months

The problem is in spacing between labels. Labels tend to fall behind the values on the y axis. Each label falls a bit further back from the actual value, althoug all the values are placed on 1th of every month. So every 4th or so label gets displayed twice. I didnt really test the solution you provi...

Left axis works fine using this: chart.getAxes().getLeft().setVisible(true); chart.getAxes().getLeft().getGrid().setVisible(false); But on right axis I tried all combinations of the following, still nothing appears: chart.getAxes().getRight().setVisible(tru...

Re: Animation example on Android

I see.

How about panning - can I get some demo code on that? I tried this, but doesnt help:

Scroll scroll = new Scroll(chart.getChart());
scroll.setAllow(ScrollMode.BOTH);
chart.setPanning(scroll);
