问题
I'm trying to create a chart in my app using MPAndroidChart.
My aim is to get a graph looking like this one:
But with some specific features.
- The graph will be wider than the screen's width so it must have a minimum width and be scrollable ( for the width I'm using this workaround, but its not scrollable ):
chart.getLayoutParams().width=100*entries.size(); - I would like to have the same kind of speech bubble on click on a bar ( I don't know if there is a way to have it and the scroll in the same time since for the scroll I guess a workaround using layout and scrollview is the only solution if this feature is not implemented yet)
and finally, when touching above one of the bar, not selecting the bar under ( which could prevent the user to scroll if there is a way to do so! ).
Is it technically possible with MPAndroidChart yet? Thanks in advance.
回答1:
Yes, it is. And please do not use ScrollView.
Read this for modifying the viewport and "making the chart wider": https://github.com/PhilJay/MPAndroidChart/wiki/Modifying-the-Viewport
The "speech bubble" you are talking about is the MarkerView, and yes, it can be displayed when scrolling as well.
