加载 ggplot2 包并使用小提琴的默认颜色创建折线图 −
x<-rnorm(25) y<-rnorm(25) Factor<-factor(sample(1:3,25,replace=TRUE)) df<-data.frame(x,y,Factor) library(ggplot2) ggplot(df,aes(x,y,colour=Factor))+geom_line()
输出
使用默认颜色的线条 ...灰色调色板
使用 scale_fill_grey 创建灰色调色板线条的折线图 −
示例
package my;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
DefaultTableModel tableModel = new DefaultTableModel(new Object[][] {
{ "Mobile Phones", "100" }, { "RAM", "200" }, { "Caps", "50" },
{ "Tablet", "80" }, { "LED", "400" }, { "Trousers", "350" },
{ "T-Shirt", "500" }, { "Hoodie", "650" }, { "Jeans", "900" } },
new Object[] { "Items", "Quantity" }
);
JTable table = new JTable(tableModel);
Font font = new Font("Verdana", Font.PLAIN, 12);
table.setFont(font);
table.setRowHeight(30);
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.add(new JScrollPane(table));
frame.setVisible(true);
}
}
这将产生以下输出 −
