Functions

@Composable
fun LineChart(data: ChartData, modifier: Modifier = Modifier, style: LineChartStyle = LineChartDefaults.style(), title: String? = null, selection: ChartSelection = rememberChartSelection(), interactionEnabled: Boolean = true, animateOnStart: Boolean = true, selectedValueFormatter: ChartValueFormatter = LineChartDefaults.selectedValueFormatter, axisValueFormatter: ChartValueFormatter = LineChartDefaults.axisValueFormatter, subtitle: String? = null)

Displays one or more aligned indexed series. A single public entry point handles both single- and multi-line data. Selection always refers to a source X index shared by all series. In compact mode, user interaction selects the middle source index represented by a bucket; programmatic source selection highlights the bucket containing that index.

@Composable
fun LiveLineChart(data: ChartData, modifier: Modifier = Modifier, style: LineChartStyle = LineChartDefaults.style(), title: String? = null, shiftDuration: Duration = 420.milliseconds, animateOnStart: Boolean = true, axisValueFormatter: ChartValueFormatter = LineChartDefaults.axisValueFormatter, subtitle: String? = null)

Displays a live window of one or more aligned indexed series. When data drops its oldest point and appends a new one, the line slides one step to the left, X-axis labels stay on their points and slide with them, and the Y axis rescales to the current window. Other changes that keep the number of points and series morph the line over shiftDuration; changes to either count redraw immediately.
