compose-graphs

Zoomable and Draggable Graphs based-on Jetpack Compose. Supports Android & iOS, Web and Desktop.

Features

• Full customization of the various parts of the graph (like the point, line between the points, highlight when selected, the values in x-axis and y-axis, etc...)
• Supports scrolling, zooming and touch drag selection

How to use

Just add the LineGraph composable and pass it a Plot with all your configuration and customisation. Please take a look at the app app to see the various customisations available. Almost every aspect of the graph is customisable. You can even override the default draw implementations and can draw a Rectangle instead of a Circle, etc. The below code renders the Orange graph that you see in the above screenshots.

@Composable
fun LineGraph1(lines: List<List<PointF>>) {
    LineGraph(
        plot = Plot(
            lines = listOf(
                Plot.Line(
                    points = lines[0],
                    connection = Plot.Connection(LightGreen600, 2.dp),
                    intersection = Plot.Intersection(LightGreen600, 5.dp),
                    highlight = Plot.Highlight(Green900, 5.dp),
                    underline = Plot.Underline(LightGreen600, 0.3F)
                ),
                Plot.Line(
                    points = lines[1], connection = Plot.Connection(Color.LightGray, 2.dp),
                    intersection = Plot.Intersection { center, point ->
                        val px = 2.dp.toPx()
                        val topStart = Offset(center.x - px, center.y - px)
                        drawRect(Color.LightGray, topLeft = topStart, Size(px * 2, px * 2))
                    },
                ),
            ),
            selection = Plot.Selection(
                highlight = Plot.Connection(
                    Green900, strokeWidth = 2.dp, pathEffect = PathEffect.dashPathEffect(
                        floatArrayOf(40F, 20F)
                    )
                )
            ),
        ),
        modifier = Modifier
            .fillMaxWidth()
            .height(180.dp)
    )
}
