Custom Labels for numeric values on Y-Axis

I would like to replace the labels on the y-axis in a bar diagram while keeping the original structure.
In my use case, I display an amount of time per day of week, which is currently displayed in minutes, but I'd like to change the format to something like 2:30 instead of 150. Is there an option for that?

Expose LineChartData's properties to public

Hi 👋 Firstly, I wanna say thank you for your helpful compose chart library. You saved me a lot of time to implement the LineChart on my current project.

I am using LineChart from your library however the design looks a bit different from yours, that's why I have do to some stuff to customize the chart. I need to determine the max and min values to draw the text label on top of the points. So I am asking for the solution that we could expose the properties to public rather than private/internal 😄

compose-charts/charts/src/main/java/me/bytebeats/views/charts/line/LineChartData.kt

Lines 19 to 32 in b853af6

	private val yMinMaxValues: Pair<Float, Float>
	get() {
	val minValue = points.minOf { it.value }
	val maxValue = points.maxOf { it.value }
	return minValue to maxValue
	}
	internal val maxY: Float
	get() = yMinMaxValues.second + (yMinMaxValues.second - yMinMaxValues.first) * padBy / 100F
	internal val minY: Float
	get() = if (startAtZero) 0F else yMinMaxValues.first - (yMinMaxValues.second - yMinMaxValues.first) * padBy / 100F
	internal val yRange: Float
	get() = maxY - minY

Feature request: custom BarChart max value

Right now, BarChart max y value is fixed on the highest data point. It would be nice to be able to set the top y value to some other value. I have some extra markers I need to put at certain Y values beyond the top bar and I'm struggling to make it render correctly.

Typo in BarChart.kt

Hey, you have a typo in compose-charts/charts/src/main/java/me/bytebeats/views/charts/bar/BarChart.kt
The classname now is BarChar instead of BarChart.

Update Kotlin & Compose

Kotlin 1.8.0 and Compose 1.3.0

@Preview is not working with PieChart

@Preview
@Composable
fun PieChartPreview() {
    Box(modifier = Modifier.height(150.dp)) {
        PieChart(
            pieChartData = PieChartData(
                slices = listOf(
                    PieChartData.Slice(25F, Color.Red),
                    PieChartData.Slice(45F, Color.Green),
                    PieChartData.Slice(20F, Color.Blue),
                ),
            ),
            sliceDrawer = SimpleSliceDrawer(sliceThickness = 100f)
        )
    }
}

I am using a Android Studio 2021.1.1 Patch 3, with Jetpack Compose 1.1.1
I can display the chart no problem on my device

Maven Package Charts

Hello, is there a maven package for the charts?

Suggesion: X value formatter

First of all, congrats for the API, it's awesome and works like a glance.

But just like in the Y axis there's a value formatter to customize how it's displayed, it'd be really useful to have the same on the X axis.

Thanks in advance, keep working! This is awesome 🚀
