ComposeCharter

A library that contains several customizable Charts that can be used in Jecpack Compose's @Composables.

Basic Usage

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

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

2. Add the dependency to your module:

dependencies {
    implementation 'com.github.nikachapo:ComposeCharter:1.0.3'
}

3. Use Chart Composables:

There is one data class that can be used for drawing Charts:

data class ChartModel(val value: Float, val color: Color, val text: String? = null)

Note: for Animations, library does not have inner implementations, you can use common Animation approach as you would do for composables, for example:

    var cyanPercentage by remember { mutableStateOf<Float?>(0f) }
    var greenPercentage by remember { mutableStateOf<Float?>(0f) }
    var yellowPercentage by remember { mutableStateOf<Float?>(0f) }

    val cyanAnimatedPercentageState = animateFloatAsState(
        targetValue = cyanPercentage ?: 0f,
        animationSpec = tween(1000)
    )

    val greenAnimatedPercentageState = animateFloatAsState(
        targetValue = greenPercentage ?: 0f,
        animationSpec = tween(1000)
    )

    val yellowAnimatedPercentageState = animateFloatAsState(
        targetValue = yellowPercentage ?: 0f,
        animationSpec = tween(1000)
    )

PieChart

PieChart(
    chartModels = listOf(
                ChartModel(cyanAnimatedPercentageState.value, Color.Cyan),
                ChartModel(greenAnimatedPercentageState.value, Color.Green),
                ChartModel(yellowAnimatedPercentageState.value, Color.Yellow)),
    chartSize = 150.dp,
    elevation = 30.dp,
    showCenterDot = true
)

DonutChart

DonutChart(
    chartModels = chartModels,
    chartSize = 150.dp,
    strokeWidth = 100f,
    elevation = 30.dp,
    cap = StrokeCap.Round
)

ColumnChart

ColumnChart(
    chartModels = chartModels,
    modifier = Modifier.fillMaxWidth(),
    height = 150.dp,
    columnWidth = 150f,
    spaceWidth = 40f,
    cornerRadius = CornerRadius(12f, 12f),
    showValues = true
)

BarChart

BarChart(
chartModels = chartModels,
modifier = Modifier
          .fillMaxWidth()
          .padding(24.dp),

    withDots = true,
    lineColors = listOf(
        MaterialTheme.colors.primary,
        MaterialTheme.colors.error
    ),
    fillColor = Color.Green
)
