What are Vico Charts?

Vico Charts is an open-source library developed by the Vico team, providing a wide range of charting options for Android developers. It offers a flexible and customizable way to visualize data, making it an ideal choice for data-driven applications. From simple line charts to complex candlestick charts, Vico Charts has got you covered.

Why Use Vico Charts in Jetpack Compose?

• Easy Integration: Vico Charts seamlessly integrates with Jetpack Compose, allowing you to leverage the power of Compose’s declarative UI and Vico’s charting capabilities.
• Customization Galore: Both Vico Charts and Jetpack Compose offer extensive customization options, giving you complete control over the look and feel of your charts.
• Performance Optimization: By using Jetpack Compose, you can take advantage of its optimizing compiler, ensuring your chart-heavy UI performs smoothly and efficiently.

Getting Started with Vico Charts in Jetpack Compose

To begin, add the Vico Charts dependency to your `build.gradle` file:

dependencies {
  implementation 'com.vico:vicocharts:1.1.0'
}

Next, create a new Compose UI component for your chart:

@Composable
fun LineChartSample() {
  // Chart content goes here
}

Basic Line Chart Example

Let’s create a simple line chart using Vico Charts in Jetpack Compose:

@Composable
fun LineChartSample() {
  LINE_CHART(
    data = listOf(
      LineChartData(10, "Jan"),
      LineChartData(20, "Feb"),
      LineChartData(30, "Mar"),
      LineChartData(40, "Apr"),
    ),
    colors = listOf(
      Color(0xFF4CAF50),
      Color(0xFF2196F3),
    ),
    chartConfig = ChartConfig(
      axisConfig = AxisConfig(
        xAxisConfig = XAxisConfig(
          axisColor = Color(0xFF9E9E9E),
          axisThickness = 2f,
        ),
        yAxisConfig = YAxisConfig(
          axisColor = Color(0xFF9E9E9E),
          axisThickness = 2f,
        ),
      ),
    ),
  )
}

This example demonstrates a basic line chart with customizable colors, axis configurations, and chart data.

Advanced Techniques

Multi-Series Charting

Visualizing multiple data sets can be achieved by using Vico Charts’ multi-series feature:

@Composable
fun MultiSeriesLineChartSample() {
  LINE_CHART(
    data = listOf(
      LineChartData(
        series = listOf(
          LineChartSeries(
            data = listOf(
              LineChartData(10, "Jan"),
              LineChartData(20, "Feb"),
              LineChartData(30, "Mar"),
              LineChartData(40, "Apr"),
            ),
          ),
          LineChartSeries(
            data = listOf(
              LineChartData(50, "Jan"),
              LineChartData(60, "Feb"),
              LineChartData(70, "Mar"),
              LineChartData(80, "Apr"),
            ),
          ),
        ),
      ),
    ),
    colors = listOf(
      Color(0xFF4CAF50),
      Color(0xFF2196F3),
    ),
    chartConfig = ChartConfig(
      axisConfig = AxisConfig(
        xAxisConfig = XAxisConfig(
          axisColor = Color(0xFF9E9E9E),
          axisThickness = 2f,
        ),
        yAxisConfig = YAxisConfig(
          axisColor = Color(0xFF9E9E9E),
          axisThickness = 2f,
        ),
      ),
    ),
  )
}

Interactive Charts

Vico Charts provides built-in support for interactive charts, allowing users to explore data in more detail:

@Composable
fun InteractiveLineChartSample() {
  LINE_CHART(
    data = listOf(
      LineChartData(
        series = listOf(
          LineChartSeries(
            data = listOf(
              LineChartData(10, "Jan"),
              LineChartData(20, "Feb"),
              LineChartData(30, "Mar"),
              LineChartData(40, "Apr"),
            ),
            onSelectionChanged = { selectedData ->
              // Handle chart selection
            },
          ),
        ),
      ),
    ),
    colors = listOf(
      Color(0xFF4CAF50),
    ),
    chartConfig = ChartConfig(
      axisConfig = AxisConfig(
        xAxisConfig = XAxisConfig(
          axisColor = Color(0xFF9E9E9E),
          axisThickness = 2f,
        ),
        yAxisConfig = YAxisConfig(
          axisColor = Color(0xFF9E9E9E),
          axisThickness = 2f,
        ),
      ),
      interactionConfig = InteractionConfig(
        selectionEnabled = true,
      ),
    ),
  )
}
