# Lightweight-charts-android

The Android Lightweight Charts is an Android wrapper of the [TradingView Lightweight Charts](https://github.com/tradingview/lightweight-charts) library.

## Requirements

- minSdkVersion 21
- Installed WebView with support of ES6

## How to use

In `/build.gradle`

```groovy
allprojects {
repositories {

mavenCentral()
}
}
```

In `/gradle_module/build.gradle`

```groovy
dependencies {
//...
implementation 'com.tradingview:lightweightcharts:3.8.0'
}
```

Add view to the layout.

```xml

```

Configure the chart layout.

```kotlin
charts_view.api.applyOptions {
layout = layoutOptions {
backgroundColor = Color.LTGRAY.toIntColor()
textColor = Color.BLACK.toIntColor()
}
localization = localizationOptions {
locale = "ru-RU"
priceFormatter = PriceFormatter(template = "{price:#2:#3}$")
timeFormatter = TimeFormatter(
locale = "ru-RU",
dateTimeFormat = DateTimeFormat.DATE_TIME
)
}
}
```

Add any series to the chart and store a reference to it.

```kotlin
lateinit var histogramSeries: SeriesApi
charts_view.api.addHistogramSeries(
onSeriesCreated = { series ->
histogramSeries = series
}
)
```

Add data to the series.

```kotlin
val data = listOf(
HistogramData(Time.BusinessDay(2019, 6, 11), 40.01f),
HistogramData(Time.BusinessDay(2019, 6, 12), 52.38f),
