1. Getting Started

Let’s dive into how to integrate the ArcChartView library into your project.

Add Maven to Your Project

First, add the JitPack repository to your root build.gradle file:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add the Dependency

Now, include the ArcChartView dependency in your app’s build.gradle file:

dependencies {
    implementation 'com.github.imaNNeoFighT:ArcChartView:1.0.3.1'
}

Once done, sync your Gradle files and grab a cup of tea while it compiles!

2. Understanding View Properties

The ArcChartView can be customized through various attributes that you can modify in XML or programmatically at runtime. Here’s an analogy to help you understand these properties:

Imagine you’re a chef preparing a special dish. Each ingredient has a specific role, like spices that enhance flavors or herbs that add aroma. Similarly, the view properties of ArcChartView act as ingredients that enhance the look and feel of your chart. Here are some key properties:

• acv_lines_count: Controls the number of lines in the chart (default: 10).
• acv_lines_space: Defines the space between lines (default: 4dp).
• acv_sections_count: Sets the number of sections in the chart (default: 8).
• acv_icon_size: Determines the size of icons (default: 32dp).

3. Setting Values and Customization

To interact with the sections of your ArcChartView, you can get or set values easily using the provided functions:

val value = myArcChartView.getSectionValue(sectionPos)
myArcChartView.setSectionValue(sectionPos, sectionValue)

Additionally, to customize filled and unfilled section colors, use:

myArcChartView.setFilledColor(sectionPos, Color.BLACK)
myArcChartView.setUnfilledColor(sectionPos, Color.LTGRAY)

4. Implementing Rotate Animation

Want to add a dynamic touch? You can implement a rotate animation for your arc chart:

val anim = ValueAnimator.ofFloat(0f, 360f).apply {
    repeatCount = ValueAnimator.INFINITE
    duration = 3000
}
anim.addUpdateListener {
    myArcChartView.startDegreeOffset = it.animatedValue as Float
}
anim.start()

5. Troubleshooting

As you build your application, you might encounter some issues. Here are a few troubleshooting ideas:

• If Gradle sync fails, double-check the repository URL and dependency declaration.
• Make sure you have the correct permissions set in your AndroidManifest.xml file for any internet-based functionalities.
• If your arc chart doesn’t display properly, ensure that the layout constraints in your XML are correctly defined.
