是否有一个很好的示例显示如何使用apache POI在PPT上绘制折线图?
我正在使用apache POIs XSLFSlide来生成PPT。我没有看到一个使用XSLFSlide绘制线的示例。

通常,此条形图具有相同的概念。只需更改为多行
public static void main(String[] args) throws Exception {
HSLFSlideShow ppt = new HSLFSlideShow();
try {
//bar chart data. The first value is the bar color, the second is the width
Object[] def = new Object[]{
Color.yellow, 40,
Color.green, 60,
Color.gray, 30,
Color.red, 80,
};
HSLFSlide slide = ppt.createSlide();
HSLFGroupShape group = new HSLFGroupShape();
//define position of the drawing in the slide
Rectangle bounds = new java.awt.Rectangle(200, 100, 350, 300);
group.setAnchor(bounds);
group.setInteriorAnchor(new java.awt.Rectangle(0, 0, 100, 100));
slide.addShape(group);
Graphics2D graphics = new PPGraphics2D(group);
//draw a simple bar graph
int x = 10, y = 10;
graphics.setFont(new Font("Arial", Font.BOLD, 10));
for (int i = 0, idx = 1; i < def.length; i+=2, idx++) {
graphics.setColor(Color.black);
int width = ((Integer)def[i+1]).intValue();
graphics.drawString("Q" + idx, x-5, y+10);
graphics.drawString(width + "%", x + width+3, y + 10);
graphics.setColor((Color)def[i]);
graphics.fill(new Rectangle(x, y, width, 10));
y += 15;
}
graphics.setColor(Color.black);
graphics.setFont(new Font("Arial", Font.BOLD, 14));
graphics.draw(group.getInteriorAnchor());
graphics.drawString("Performance", x + 30, y + 10);
FileOutputStream out = new FileOutputStream("hslf-graphics.ppt");
ppt.write(out);
out.close();
} finally {
ppt.close();
}
}
