MPAndroidChart

MPAndroidChart supports a wide variety of chart visualizations, including:

• LineChart: Simple designs, cubic lines, and gradient fills.
• BarChart: Standard, grouped DataSets, and Horizontal BarCharts.
• CombinedChart: Overlays multiple chart types (e.g., bar and line charts).
• PieChart: Circular charts with selection support.
• ScatterChart: Data points using various shapes (squares, triangles, circles, etc.).
• CandlestickChart: Specialized for financial data.
• BubbleChart: Bubbles where area indicates the yValue.
• RadarChart: Spider web style charts.

You can explore how to implement various charts by:

1. Downloading the MPAndroidChart Example App from the Play Store.
2. Reviewing the source code in the repository.

For Maven-based projects, add the JitPack repository to your pom.xml and include the MPAndroidChart dependency with the group ID com.github.PhilJay.

<!-- <repositories> section of pom.xml -->
<repository>
    <id>jitpack.io</id>
   <url>https://jitpack.io</url>
</repository>

<!-- <dependencies> section of pom.xml -->
<dependency>
    <groupId>com.github.PhilJay</groupId>
    <artifactId>MPAndroidChart</artifactId>
    <version>v3.1.0</version>
</dependency>

To use MPAndroidChart in an Android project, add the JitPack repository to your repositories block and then add the library as an implementation dependency in your dependencies block.

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

dependencies {
    implementation 'com.github.PhilJay:MPAndroidChart:v3.1.0'
}

To duplicate an entry, use the copy() method, which creates a new Entry with the same x, y, and data values.

To check if two entries are logically equivalent, use equalTo(Entry e). This method compares the data, x, and y values using a small epsilon (Utils.FLOAT_EPSILON) to account for floating-point precision errors. Note that equalTo is distinct from the standard equals method as it focuses on value equality rather than hash-code equality.

Entry e1 = new Entry(1f, 10f);
Entry e2 = e1.copy();

boolean isSame = e1.equalTo(e2);

The Entry class represents a single data point in a chart. It contains an x value and a y value (the actual value of the entry). You can also attach an optional Drawable icon or an arbitrary Object for additional data to each entry.

Constructors

• Entry(): Default empty constructor.
• Entry(float x, float y): Basic entry with x and y coordinates.
• Entry(float x, float y, Object data): Entry with x, y, and custom data.
• Entry(float x, float y, Drawable icon): Entry with x, y, and an icon.
• Entry(float x, float y, Drawable icon, Object data): Full entry with x, y, icon, and custom data.

// Basic entry
Entry entry = new Entry(1f, 10f);

// Entry with custom data
Entry entryWithData = new Entry(2f, 20f, "my_metadata");

// Entry with an icon and data
Entry entryWithIcon = new Entry(3f, 30f, myDrawable, myData);

You can retrieve or update the x-coordinate of an Entry using getX() and setX(float x). The y-coordinate is managed via the BaseEntry parent class using getY() and setY(float y).

Entry entry = new Entry(1f, 5f);
float x = entry.getX(); // returns 1.0f
entry.setX(2f);
