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...

Thank you, that solved the problem.

It would be nice to have this solution built in - anyone using custom labels would want it and it would've been a paint to do this on my own.

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

So as the chart is zoomed out, the labels are all over each other. Any solution to this?

I tried your solution now, well, a version of it. It actually fixed the problem. I simply used the method getCustomLabels and added each date in the same loop where I am adding the actual values chart.getSeries(0).add(new DateTime(dataStore.getDataDatetime().getTime()), dataStore.getDoubleValue()); ...

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...

I am having problems with displaying monthly time step. I have 12 values on the chart and each of them is started on the first day of month, but for some reason some months are displayed twice in a row. This is the code used the set the time step: series.getXValues().setDateTime(true); chart.getAxes...

That was it, works fine now.
Thank you.

I cant get the right axis to be displayed. 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...

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);

Hello, I am trying to get animation working on my Android charts. I just need a simple grow animation on bar charts, but I cant find any example or tutorial on that. This is what I came up with, but it doesnt do anything: SeriesAnimation seriesAnimation = new SeriesAnimation(); seriesAnimation.setAc...
