I want to implement a feedback/rating chart in my android app.(it is like when you open the google play and check an app's feedback there is a colourful graph from users who had voted it) Can anyone help me how to start that? I appreciate any help you can provide.
Use MPAndroidChart, or another Chart library external to the default libraries. It's difficult to implement a bar graph or any sort of graph on Android; you'd have to make a listview, and it would have to be oriented horizontally.

I need to present the data in android in the form of a Line graph and give the users a feature to be able to mark certain portions of the graph (starting and ending marker).
I know I can easily implement the graph using some famous libraries like MPChart and AnyChart but the thing is very straight about the feature like this:
I am truly clueless about how am I gonna do this.
Any help or any link to the related blog will gonna help me a lot.
Much thanks in Advance _
I am curious if it is possible to adjust the route after a maneuver like you can see in this video from the Mapbox website: https://www.mapbox.com/assets/use-cases-navigation-sdk-272b22ac06adc9a4275dcc13624112d8.mp4
Goal is to hide the route which has already been traversed.
I am using the mapbox navigation android sdk but didn't find anything in the docs.
Thanks in advance!
Hey 👋🏼 thanks for checking out the Android Navigation SDK! You're correct, unfortunately we currently don't have APIs to support this use-case.
If you'd like, it would be 💯 if you cut a ticket for feature request with a .gif of this video: https://github.com/mapbox/mapbox-navigation-android/issues
Thanks again and let us know if you have any other questions.
I want to implement draggable line chart for android.
• This is exactly i want to
I have referred many charts library like mpandroid, android-plot, hz-graphview among all line charts are static.
P.S I'm not asking anyone to implement this all i need is guidelines or any open source library will be appreciated.
I would recommend you to start with trying out this sample from Android developers-site to get started with drawing in canvas if you haven't done so before. Then start to modify the sample to use onTouchEvent for dragging the objects, and take it from there.

It seems MPAndroidChart has dragging feature. Check it out. BTW I haven't tried it yet.

A library is now available with the same feature mentioned.

Achieved same functionality with this library with minor modification.
I'm developing an android app and I need do implement a pie chart. I've searching for some alternatives but the APIs that I've found are a little limited in terms of animations and graph customization.
Does anyone knows the best way to implement a pie chart that can rotate when touched?
Thanks in advance.
I like Charts4j. You can use it to create a few kinds of pie charts. If you put the resulting drawables into a view you could probably figure out some way to interpret touch events to trigger rotate animation effects.
Is it possible to animate the chart obtained from google chart api in android ? If so how can we do that ?
I don't think there is a native google chart api for android so no, it is not possible to animate the chart, the last time I used it, I had to generate the URL from java code and display it in a WebView. I think you need to use javascript for animation like this: animation charts for Android. Hope it helps
