Mpandroidchart: Scrolling and pagination

[alex-marochko]

Hi. Thanks for your nice library.

Please, give me an advice - how can i add horizontal scrolling behavior like ViewPager has? Thanks for answer!

P.S. Sorry for my (possibly) bad English.

Horizontal scrolling of what? The chart content?

You can do that by zooming in an then use your finger to scroll (like the view pager). If you want to zoom in by default, you can modify the viewport to do so:

Thanks for answering.
Yes, scrolling of chart content, with 'pages effect', when every 'page' snaps while scrolling. For example, if i want to show only one whole week at time at XAxis - from sunday to saturday, i can set

lineChart.setVisibleXRangeMaximum(7.0f); lineChart.setVisibleXRangeMinimum(7.0f);
(7 days of week) but i don't now how to make chart not to stop in a week middle while scroll/fling. Is that possible?

Hi.
I tried to change the library to get this effect, but didn't succeed - page scrolling was not smooth. I didn't find any other free lib with all necessary properties. That's why I built absolutely crazy construction... I placed transparent (but touchable) ViewPager above the chart. ))) I connect its scrolling to chart's one via OnDragListener and OnPageChangeListener. So ViewPager's scroll 'snapping' animation became chart's one.
That's not easy, especially if number of pages changes. But if you have no other solutions - it's not too hard.
I remember, there also was an issue about separating scrolling gestures (these are for ViewPager) and touches for selecting data at chart. If you need, I'll show you necessary parts of my code.

How to detect the scroll finish event in line chart ? Not asking about the end of the chart. Just a listener to listen to the scroll event finish.
