Gradient bars

A vertical bar chart with gradient fills that grow in, staggered left to right.

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 GradientBars(
    values: List<Float> = listOf(0.45f, 0.72f, 0.58f, 0.9f, 0.64f, 0.81f, 0.52f),
    modifier: Modifier = Modifier,
) {
    val grow = remember { Animatable(0f) }
    LaunchedEffect(Unit) {
        grow.animateTo(1f, tween(900, easing = EaseOutCubic))
    }
    val top = Color(0xFF6366F1)
    val bottom = Color(0xFF22D3EE)
    Canvas(modifier.fillMaxWidth().height(120.dp)) {
        val gap = 10.dp.toPx()
        val bw = (size.width - gap * (values.size - 1)) / values.size
        values.forEachIndexed { i, v ->
            val h = size.height * v * grow.value
            val x = i * (bw + gap)
            drawRoundRect(
                brush = Brush.verticalGradient(listOf(top, bottom)),
                topLeft = Offset(x, size.height - h),
                size = Size(bw, h),
                cornerRadius = CornerRadius(6.dp.toPx()),
            )
        }
    }
}
