Simple custom chart views for Android

How to add

Add it in your root build.gradle at the end of repositories:

dependencies {
    allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}
}

Add it in your module build.gradle:

dependencies {
    //column chart view
    implementation 'com.github.jaskelai.charts:columnchartview:VERSION'
    //pie chart view
    implementation 'com.github.jaskelai.charts:piechartview:VERSION'
}

How to use

Add the view to layout:

<com.github.jaskelai.chartcustomview.ColumnChartView
        android:id="@+id/chartview_main"
        android:layout_width="300dp"
        android:layout_height="300dp" />

or

<com.github.jaskelai.piechartview.PieChartView
            android:id="@+id/chart_pie"
            android:layout_width="300dp"
            android:layout_height="300dp" />

Column chart view

You can convert your list or map to column chart data by library's extensions:

val map: Map<String, Int> = mapOf("AA" to 20, "BB" to 30, "CC" to 100)
val chartDataList: List<ChartData> = map.toChartData()

val list: List<Float> = listOf(20F, 50F, 80F)
val chartDataList: List<ChartData> = list.toChartData()

Set values to column chart:

val map: Map<String, Int> = mapOf("AA" to 20, "BB" to 30, "CC" to 100)
val chartDataList: List<ChartData> = map.toChartData()
chartview_main.values = chartDataList

You can specify margins between columns (0 by default):

<com.github.jaskelai.chartcustomview.ColumnChartView
        android:id="@+id/chartview_main"
        android:layout_width="300dp"
        android:layout_height="300dp"
        app:chartMargins="12dp" />

You can specify colors (cyan and pink by default):

<com.github.jaskelai.chartcustomview.ColumnChartView
        android:id="@+id/chartview_main"
        android:layout_width="300dp"
        android:layout_height="300dp"
        app:colorTop="@color/colorPrimary"
	app:colorBottom="@color/colorAccent" />

You can specify text size (16sp by default):

<com.github.jaskelai.chartcustomview.ColumnChartView
        android:id="@+id/chartview_main"
        android:layout_width="300dp"
        android:layout_height="300dp"
        app:textSize="20sp" />

You can specify filling (false by default):

<com.github.jaskelai.chartcustomview.ColumnChartView
        android:id="@+id/chartview_main"
        android:layout_width="300dp"
        android:layout_height="300dp"
        app:isFilled="true" />

Pie chart view

You can specify pie margins (0 by default):

<com.github.jaskelai.piechartview.PieChartView
            android:id="@+id/chart_pie"
            android:layout_width="300dp"
            android:layout_height="300dp"
	    app:pieMargins="4dp"/>

You can specify radius (0 by default):

<com.github.jaskelai.piechartview.PieChartView
            android:id="@+id/chart_pie"
            android:layout_width="300dp"
            android:layout_height="300dp"
	    app:radius="4dp"/>
