Offers a set of customizable chart components, including BarChart, BubbleChart, Dial, GasBottle, LineChart, and PieChart. Supports theming and animation for enhanced visual appeal and user experience.
Go to charts folder and run assemble[Debug|Release]. This results in an aar file which can then be copied/imported to your project as any other aar artifact.

The library provides following components:
Most of the components have arguments like:
Before using component the BarChartData has to be prepared:
val barChartData = BarChartData(
categories = listOf(
BarChartCategory(
name = "Bar Chart 1",
entries = listOf(
BarChartEntry(
x = "primary",
y = 17f,
color = Color.Yellow,
),
BarChartEntry(
x = "secondary",
y = 30f,
color = Color.Red,
),
)
),
BarChartCategory(
name = "Bar Chart 2",
entries = listOf(
BarChartEntry(
x = ,
y = -,
color = Color.Yellow,
),
BarChartEntry(
x = ,
y = -,
color = Color.Red,
),
)
),
)
)
BarChart(
data = barChartData,
config = BarChartConfig(
thickness = 14.dp,
cornerRadius = 7.dp,
),
modifier = Modifier.height(500.dp),
animation = ChartAnimation.Sequenced(),
)
There is another component called BarChartWithLegend. It renders bar chart with legend.
Before using component the list of Bubble has to be prepared:
val bubbles = listOf(
Bubble(
name = "first",
value = 1.2f,
icon = Icons.Default.Album,
color = Color.Yellow
),
Bubble(
name = "second",
value = 4.6f,
icon = Icons.Default.House,
color = Color.Green
),
Bubble(
name = "third",
value = 6.9f,
icon = Icons.Default.Bed,
color = Color.Blue
),
)
BubbleChart(
bubbles = bubbles,
modifier = Modifier.size(300.dp),
animation = ChartAnimation.Sequenced(),
)
Dial(
value = 22,
minValue = -20,
maxValue = 50,
modifier = Modifier.fillMaxWidth(),
animation = ChartAnimation.Simple {
spring(
dampingRatio = Spring.DampingRatioMediumBouncy,
stiffness = Spring.StiffnessLow
)
},
config = DialConfig(
thickness = 20.dp,
roundCorners = true,
),
mainLabel = {
Column(
horizontalAlignment = Alignment.CenterHorizontally
) {
Text(
text = "$it°C",
style = MaterialTheme.typography.h4,
color = Color.Yellow
)
Text(
text = "outside temperature",
style = MaterialTheme.typography.body2,
modifier = Modifier.padding(top = dp)
)
}
}
)
There is another component ProcentageDial. It accepts only one data argument percentage in [0-100] range.
GasBottle(
percentage = 75f,
modifier = Modifier.size(width = 200.dp, height = 300.dp),
animation = ChartAnimation.Simple {
spring(
dampingRatio = Spring.DampingRatioMediumBouncy,
stiffness = Spring.StiffnessVeryLow
)
}
)
Before using component the LineChartData has to be prepared:
val lineData = remember {
LineChartData(
series = (1..3).map {
LineChartSeries(
dataName = "data $it",
lineColor = listOf(
Color.Yellow,
Color.Red,
Color.Blue,
)[it - 1],
listOfPoints = (1..10).map { point ->
LineChartPoint(
x = DateTime.now().minus(TimeSpan(point * 24 * 60 * * )).unixMillisLong,
y = ().random().toFloat(),
)
}
)
},
)
}
LineChart(
lineChartData = lineData,
modifier = Modifier.height(300.dp),
xAxisLabel = {
Text(
fontSize = 12.sp,
text = DateTime.fromUnix(it as Long).format("yyyy-MM-dd"),
textAlign = TextAlign.Center
)
},
overlayHeaderLabel = {
Text(
text = DateTime.fromUnix(it as Long).format("yyyy-MM-dd"),
style = MaterialTheme.typography.overline
)
},
animation = ChartAnimation.Sequenced()
)
Before using component the list of PieChartData has to be prepared:
val data = listOf(
PieChartData(
name = "Data 1",
value = 10.0,
color = Color.Yellow,
),
PieChartData(
name = "Data 2",
value = 20.0,
color = Color.Green,
),
PieChartData(
name = "Data 3",
value = 30.0,
color = Color.Blue,
),
PieChartData(
name = "Data 4",
value = 40.0,
color = Color.Red,
)
)
PieChart(
data = data,
modifier = Modifier.size(300.dp),
config = PieChartConfig(
thickness = 40.dp
),
)
By default the thickness is Dp.Infinity, it means the chart will be fully filled.
The easiest way to set the same colors for all charts is to provide ChartColors in the app theme.
private val chartColors = ChartColors(
primary = Color.Green,
grid = Color.LightGray,
surface = Color.White,
fullGasBottle = Color.Green,
emptyGasBottle = Color.Red,
overlayLine = Color.Magenta
)
@Composable
fun AppTheme(
darkTheme: Boolean = isSystemInDarkTheme(),
content: @Composable () -> Unit,
) {
CompositionLocalProvider(
// ...
LocalChartColors provides chartColors,
) {
MaterialTheme(
// ...
content = content,
)
}
}
There is also default ChartColors provided by the library. It uses the default color set from MaterialTheme.
LocalChartColors provides ChartDefaults.chartColors()
Each chart has its own color set which can be used like:
BarChart(
data = barChartData,
colors = BarChartColors(grid = Color.LightGray)
)
Also there is possibility to use ChartColors inside the specific chart:
BarChart(
data = barChartData,
colors = ChartColors(...).barChartColors,
)
