How to draw area chart in Android using MPAndroidChart?

I am looking for a way to draw area chart using MPAndroidChart. I am aware , I can use StackedBar Chart but that doesn't quite serve the purpose.
Is there a way to draw Area chart such as shown below using MPAndroidChart and if not what might be the suitable alternate?

you can make chart as you want using MPAndroidChart.
I tested using sample app in google Play Store(try search 'MPAndroidChart').
try multiLineChart and make option Toggle Filled. I think this is what you're looking for.

That is not yet supported. You can create an issue in the AChartEngine tracker and ask for this to be implemented.

how to replace the legends of Piechart using achartengine API?

I am Using Achartengine Api for drawing pie chart. I am getting the legends displayed at the bottom of the Pie chart horizontally. but I want to display it on the right side of the Pie chart vertically. I heard that it can be done using setMargins() method . if I can use that please explain how to use that.
Thank you in advance.

The setMargins() API call is, as the name suggests, for setting the margins around the chart. You cannot move the legend using this and you actually cannot move the legend at all with AChartEngine. You can hide it.
