Pie

A classic pie chart whose slices reveal with an iris wipe from the center.

Installation

caveui components are copy-paste Jetpack Compose built entirely on Material 3 — there's no caveui dependency to add. Make sure Material 3 is on your classpath (it ships with the Compose BOM), then copy the Usage snippet below into your project.

kotlin

// build.gradle.kts (module)
dependencies {
    implementation(platform("androidx.compose:compose-bom:2025.06.00"))
    implementation("androidx.compose.material3:material3")
}

Usage

kotlin

@Composable
fun PieChart(
    slices: List<Pair<Float, Color>> = listOf(
        0.35f to Color(0xFF6366F1), 0.25f to Color(0xFF22D3EE),
        0.22f to Color(0xFFF59E0B), 0.18f to Color(0xFFF43F5E),
    ),
    modifier: Modifier = Modifier,
) {
    val sweep by animateFloatAsState(1f, tween(1000, easing = EaseOutCubic), label = "s")
    Canvas(modifier.size(140.dp)) {
        var start = -90f
        slices.forEach { (frac, color) ->
            val deg = 360f * frac
            drawArc(color, start, deg * sweep, useCenter = true)
            start += deg
        }
    }
}
