plotly.java

A third-party Java wrapper for plotly.js

What is plotly.java?

Plotly.java is a third-party Java wrapper for the Plotly JavaScript open source graphing library, one of the finest graphing libraries available. plotly.java lets you generate a wide range of JavaScript/HTML charts.

Plotly.java was developed as part of the Tablesaw Java dataframe library. Dependencies on Tablesaw have now been removed to make it easier to incorporate visualizations into a broad range of Java applications.

An Example:

package tech.tablesaw.examples;

import tech.tablesaw.plotly.Plot;
import tech.tablesaw.plotly.components.Figure;
import tech.tablesaw.plotly.components.Layout;
import tech.tablesaw.plotly.traces.ScatterTrace;

public class AreaPlotExample {

  /** Creates a simple area plot with an index (observation number) x axis */
  public static void main(String[] args) throws Exception {

    String title = "Boston Robberies: 1966-1975";
    double[] observation = {1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0};
    double[] count = {41.0, 39.0, 50.0, 40.0, 43.0, 38.0, 44.0, 35.0, 39.0, 35.0, 29.0, 49.0};

    Layout layout = Layout.builder(title, "Month", "Robberies").build();
    ScatterTrace trace =
            ScatterTrace.builder(observation, count)
                    .mode(ScatterTrace.Mode.LINE)
                    .fill(ScatterTrace.Fill.TO_NEXT_Y)
                    .fillColor("#b987fb")
                    .build();
    Plot.show(new Figure(layout, trace));
  }
}
