We have released a new chart library fully built-in Compose and Kotlin. You can check it out in our GitHub repo. Some of its features:

• Line Charts
• Bar Charts
• Grouped Bar Charts
• Pie Charts
• Donut Charts
• Combined Charts
Charts are fully customizable with a Compose taste. Additionally, YCharts has also accessibility support.

Feel free to check out YCharts here, and provide us with any feedback you may have

[Kevin Del Castillo]

One suggestion, in your README code blocks set the language of the block to kotlin to get syntax highlighting

```kotlin

```

[Landry Norris]

Have y’all considered compose multiplatform support? Curious if there’s any android dependency or if this could be moved to support JVM or even native compose.

I like how the first dot on the linechart is clipped, but dislike how the third one isn't 😂, but I've got a feeling I'm going to enjoy using this library sometime very soon!

[Deepak k.k]

@Kevin Del Castillo We will update the README, Thank you for the suggestion

[Deepak k.k]

@Landry Norris As of now we are considered only for android. Soon we will start for multi-platform

[Deepak k.k]

@czuckie We will look into that issue, Thank you for your feedback

Looks interesting. API seems rather raw. Also it is not clear, if you support interactivity.

[Deepak k.k]

Yes @altavir We are supporting user interactions

[altavir]

Ah, and it seems it does not support desktop target. It's a pity.

[Deepak k.k]

@altavir We are on it

[Luigi Giustiniani]

hi! I am trying to use your library for line chart, but Y labels never matching to the Y point value. This is a bug or I don't use correctly your library?

[Deepak k.k]

Could you help me to understand more, @Luigi Giustiniani

[Luigi Giustiniani]

The max Y value of my dataset (21f) is not drawn on the top of the graph, so I cannot calculate the correct Y scale and the corresponding Y label

[Luigi Giustiniani]

This is my code block

val yAxisData = AxisData.Builder()
                .steps(5)
                .labelAndAxisLinePadding(20.dp)
                .labelData { i ->
                    // Add yMin to get the negative axis values to the scale
                    val yMin = pointsData.minOf { it.y }
                    val yScale = 5
                    (yMin + (i * yScale)).formatToSinglePrecision()
                }.build()

[Deepak k.k]

@Luigi Giustiniani In the above graph YAxis data is proper as per your code, Could you provide the data set

[Luigi Giustiniani]

This is my test dataset

val pointsData: List<Point> =
                listOf(
                    Point(1f, 19f),
                    Point(2f, 10f),
                    Point(3f, 10f),
                    Point(4f, 11f),
                    Point(5f, 11f),
                    Point(6f, 11f),
                    Point(7f, 11f),
                    Point(8f, 12f),
                    Point(9f, 13f),
                    Point(10f, 15f),
                    Point(11f, 18f),
                    Point(12f, 21f),
                    Point(13f, 18f),
                    Point(14f, 18f),
                    Point(15f, 21f),
                    Point(16f, 19f),
                    Point(17f, 19f),
                    Point(18f, 19f),
                    Point(19f, 19f),
                    Point(20f, 19f),
                    Point(21f, 20f),
                    Point(22f, 20f),
                    Point(23f, 20f),
                    Point(24f, 19f),
                    Point(25f, 19f),
                    Point(26f, 19f),
                    Point(27f, 19f),
                    Point(28f, 19f),
                    Point(29f, 19f),
                    Point(30f, 19f),
                    Point(31f, 19f),
                    Point(32f, 19f),
                    Point(33f, 19f),
                    Point(34f, 19f),
                    Point(35f, 19f),
                    Point(36f, 19f),
                    Point(37f, 19f),
                    Point(38f, 19f)

Hi @Luigi Giustiniani, Thank you for reporting the issue, We are on it. As a quick fix, you can modify the source code of yStep value calculation, in two place
1- As part yAxisDataBuilder
”

.labelData { i ->
    // Add yMin to get the negative axis values to the scale
    val yMin = pointsData.minOf { it.y }
    val yMax = pointsData.maxOf { it.y }
    val yScale = (yMax - yMin)/steps
    ((i * yScale) + yMin).formatToSinglePrecision()
}

2- LineChartExtension.kt
Line number: 31-> return Triple(yMin, yMax, temp)

we can move the discussion to the #science chat. I understand it is not exactly about science, but the discussion about plots is mostly there.

[Paul Meshkovsky]

How about WEB?

[altavir]

There are a lot of plotting libraries for web

[Paul Meshkovsky]

supporting jb-compose ?

[altavir]

You can use React/plain js components inside comopse for web. We can discuss it in #science
