How to use AAChartCore-Kotlin

As an AI language model, I don't have the ability to perform coding tasks, but I can provide you with the steps on how to use AAChartCore-Kotlin. Here are the steps:

1. Install the AAChartCore-Kotlin library in your project. You can do this by adding the following dependency to your Gradle file:

dependencies {
  implementation 'com.github.AAChartModel:AAChartCore-Kotlin:v1.0.6'
}

2. Create an instance of the `AAChartModel` class.

val aaChartModel = AAChartModel()
  .chartType(AAChartType.Area)
  .title("Monthly Average Temperature")
  .subtitle("Source: WorldClimate.com")
  .xAxisLabelsEnabled(false)
  .yAxisTitle("Temperature (°C)")
  .yAxisPlotLines(arrayOf(
    AAPlotLines()
      .value(0f)
      .width(1f)
      .color("#808080")))
  .series(arrayOf(
    AASeriesElement()
      .name("Tokyo")
      .data(arrayOf(7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6)),
    AASeriesElement()
      .name("New York")
      .data(arrayOf(-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5)),
    AASeriesElement()
      .name("Berlin")
      .data(arrayOf(-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0)),
    AASeriesElement()
      .name("London")
      .data(arrayOf(3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8))
  ))

3. Create an instance of the `AAChartView` class and set the `AAChartModel` instance to it.

val aaChartView = findViewById<AAChartView>(R.id.aa_chart_view)
aaChartView.aa_drawChartWithChartModel(aaChartModel)

4. Customize your chart by setting additional properties on the `AAChartModel` instance. You can refer to the AAChartCore-Kotlin documentation for a list of available properties and methods.

That's it! You can now display your chart on your app.
