I'm a new MPAndroidChart user.
The examples I have found on-line and the Wiki here all give the setDescription() prototype as:
setDescription(String desc)`
However, mChart.setDescription("");
does not compile for me and AndroidStudio->Go To Declaration tells me the declaration for setDescription defined in Chart.java is :
public void setDescription(Description desc) {
this.mDescription = desc;
}
And the Description constructor in Description.java does not take a String.
How do I set the description (or at least turn it off)? Am I pointing to the wrong libraries?
Here is my app's gradle file:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
allprojects {
repositories {
maven { url "https://jitpack.io" }
}
}
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
And, the module gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.example.android.nbmc_hbmc"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.github.PhilJay:MPAndroidChart:v3.0.1'
compile 'com.google.android.gms:play-services-auth:10.0.1'
compile 'pub.devrel:easypermissions:0.2.1'
testCompile 'junit:junit:4.12'
}
And this is my chart code. It compiles and shows the chart but it has the Description Label "Description Label" that I can't change or turn off.
import com.github.mikephil.charting.charts.LineChart;
import com.github.mikephil.charting.components.Description;
import com.github.mikephil.charting.data.Entry;
import com.github.mikephil.charting.data.LineData;
import com.github.mikephil.charting.data.LineDataSet;
import com.github.mikephil.charting.interfaces.datasets.ILineDataSet;
import java.util.ArrayList;
import java.util.List;
import static com.example.android.nbmc_hbmc.R.id.chart;
public class NbmcEcgGraphActivity extends Activity {
private RelativeLayout mainLayout;
private LineChart mChart;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ecggraph);
mainLayout = (RelativeLayout) findViewById(R.id.activity_ecggraph);
// Create new line chart
LineChart mChart = (LineChart) findViewById(chart);
mChart.setDescription(new Description());
mChart.setNoDataText("No Data Yet");
It looks like the wiki is out of date!
The correct syntax in MPAndroidChart
3.0.1 is
mChart.getDescription().setText("Description of my chart");
