java 导入plotly

To import Plotly in Java, you can use the Plotly Java API. Here's an example:

1. First, you need to create a Maven project and add the following dependency to your pom.xml file:

<dependency>
  <groupId>org.plotly</groupId>
  <artifactId>plotly</artifactId>
  <version>1.0.0</version>
</dependency>

2. Next, you can create a basic Plotly chart in Java using the following code:

import org.plotly.Chart;
import org.plotly.Layout;
import org.plotly.Trace;

import java.util.ArrayList;
import java.util.List;

public class PlotlyExample {

  public static void main(String[] args) {
    // Create a list of x values
    List<Double> xValues = new ArrayList<>();
    for (int i = 0; i <= 10; i++) {
      xValues.add((double) i);
    }

    // Create a list of y values
    List<Double> yValues = new ArrayList<>();
    for (int i = 0; i <= 10; i++) {
      yValues.add((double) (i * i));
    }

    // Create a trace
    Trace trace = Trace.scatter(xValues, yValues);

    // Create a layout
    Layout layout = new Layout.LayoutBuilder("My Chart", "x-axis label", "y-axis label")
        .build();

    // Create a chart and display it
    Chart chart = new Chart.ChartBuilder().setTraces(trace).setLayout(layout).build();
    chart.plot();
  }
}

This will create a scatter plot with x values ranging from 0 to 10 and y values equal to their corresponding x values squared. The chart will be displayed in a new window when you run the code.
