An Android library that makes it easy to visualize your data.

spider_chart

Download 🔗

In your project’s top-level build.gradle file, ensure that JitPack’s Maven repository is included:

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

Then, in your app-level build.gradle file, declare SpiderChart as a dependency:

dependencies {
    implementation 'com.github.nikolajakshic:spiderchart:1.0.2'
}

Usage 🔗

Define it in the layout file:

<com.nikola.jakshic.spiderchart.SpiderChart
    android:id="@+id/spider_chart"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Then capture an instance from the layout:

SpiderChart spiderChart = findViewById(R.id.spider_chart);

Add data:

float[] values1 = {45f, 82f, 76f, 55f, 55f, 55f}; // values must be in the range 0..100
float[] values2 = {85f, 72f, 41f, 75f, 75f, 75f}; // values must be in the range 0..100

int color1 = Color.argb(125, 193, 230, 219);
int color2 = Color.argb(125, 209, 217, 234);

SpiderData data1 = new SpiderData(values1, color1);
SpiderData data2 = new SpiderData(values2, color2);

List<String> labels = Arrays.asList("ART0", "ART1", "ART2", "ART3", "ART4", "ART5");
List<SpiderData> data = Arrays.asList(data1, data2);

spiderChart.setLabels(labels);
spiderChart.setData(data);

spiderChart.refresh(); // apply changes

Use styling functions:

spiderChart.setLabelSize(13f);
spiderChart.setLabelColor(Color.GRAY);
spiderChart.setLabelMarginSize(10f);
spiderChart.setWebColor(Color.GRAY);
spiderChart.setWebBackgroundColor(Color.WHITE);
spiderChart.setWebStrokeWidth(1f);
spiderChart.setWebEdgeColor(Color.BLACK);
spiderChart.setWebEdgeStrokeWidth(1.5f);
spiderChart.setRotationAngle(90f);
spiderChart.setDrawLabels(true);
spiderChart.setDrawWeb(true);
        
spiderChart.refresh(); // apply changes
