Show a subset of points on an AndroidPlot line chart

Question

I've been working with Androidplot library for generating line plots and be able to do zoom and pan, so I'm using a modified version of XYPlotZoomPan class.

My current chart is showing some values per day, in a range of dates, so if I'm showing 7 days the domain axis is readable but if I'm trying to show 30 days it turns into a mess.

My goal is to show 7 days and have the option of scrolling through the rest of the chart that is not shown.

The only function that handles boundaries is setDomainBoundaries, currently I've tried this:

  setDomainBoundaries(min, max, BoundaryMode.FIXED);

But it lets me show values inside this range and I'm loosing the ability for panning through the rest of the days.

Does someone have an a idea how I can do that? Thanks.

Answer 1

You can create your own domain value format with myplot.setDomainValueFormat(Format f). From here you can create your own formatter.

Another option you can look at is setDomainStep, a good example of that can be found here
