Marker .marker()

The Marker feature in Jplotlib allows you to add visual markers to data points in your plots, making it easier to identify individual data points. Jplotlib provides a variety of marker types that you can use to customize the appearance of your data points.

Available Marker Types:

Currently, Jplotlib provides three marker types:

• Marker.NONE: This value indicates no markers will be shown at the data points.

• Marker.CIRCLE: This value adds circular markers at the data points.

• Marker.SQUARE: This value adds square markers at the data points.

Example Usage:

import io.github.manishdait.jplotlib.Jplotlib;
import io.github.manishdait.jplotlib.defaults.marker.Marker;

public class App {
  public static void main(String[] args) {
    double[] y1 = {1, 2, 3, 4};
    double[] y2 = {2.5, 5.1, 3.9, 6.2};
    double[] y3 = {0, 3, 4, 7};

    Jplotlib jplotlib = new Jplotlib();
    jplotlib.plot(y1)
      .marker(Marker.NONE);
    jplotlib.plot(y2)
      .marker(Marker.CIRCLE);
    jplotlib.plot(y3)
      .marker(Marker.SQUARE);
    jplotlib.show();
  }
}

In above example we use .marker(Marker.Circle) to set marker as circle , .marker(Marker.Square) to set marker as square and .marker(Marker.NONE) to set no marker, Marker.NONE is the default marker style.

Setting Marker Color:

You can customize the color of the markers using the .markerColor() method. This method accepts either the LibColor enum or java.awt.Color. You can find the available colors in the LibColor Enum section below.

Example Usage:

import java.awt.Color;

import io.github.manishdait.jplotlib.Jplotlib;
import io.github.manishdait.jplotlib.defaults.color.LibColor;
import io.github.manishdait.jplotlib.defaults.marker.Marker;

public class App {
  public static void main(String[] args) {
    double[] y1 = {0, 3, 4, 7};
    double[] y2 = {2.5, 5.1, 3.9, 6.2};

    Jplotlib jplotlib = new Jplotlib();
    jplotlib.plot(y1)
      .marker(Marker.CIRCLE)
      .markerColor(LibColor.GREEN.getColor());
    jplotlib.plot(y2)
      .marker(Marker.SQUARE)
      .markerColor(Color.MAGENTA);
    jplotlib.show();
  }
}

In above we use .markerColor(LibColor.GREEN.getColor()) method to set the marker color to green using the LibColor enum and .markerColor(Color.MAGENTA) from java.awt.Color.

Setting Marker Size:

To adjust the size of the markers, you can use the .markerSize() method, which takes a value between 1 to 10. Larger values will result in bigger markers.

Example Usage:

import io.github.manishdait.jplotlib.Jplotlib;
import io.github.manishdait.jplotlib.defaults.marker.Marker;

public class App {
  public static void main(String[] args) {
    double[] y1 = {0, 3, 4, 7};
    double[] y2 = {2.5, 5.1, 3.9, 6.2};

    Jplotlib jplotlib = new Jplotlib();
    jplotlib.plot(y1)
      .marker(Marker.CIRCLE)
      .markerSize(4);
    jplotlib.plot(y2)
      .marker(Marker.SQUARE)
      .markerSize(10);
    jplotlib.show();
  }
}

In above we use .markerSize(4) and .markerSize(10) to set marker size and 4 and 10 respectivly.

You can use the .marker() feature to enhance the visibility of data points in your plots and tailor the markers according to your preferences.
