To draw on a buffered image, create a graphics context on the buffered image. // Create a graphics context on the buffered image Graphics2D g2d = bimage.createGraphics(); // Draw on the image g2d.setColor(Color.red); g2d.fill(new Ellipse2D.Float(0, 0
封装了一个简单的2d绘图函数 from matplotlib import pyplot as plt def plot_line(*args, **kw): """ :param args: x,y,... :param kw: name, xlabel, ylabel,... :return: """ name = 'line_chart' if 'name' in kw: name = kw['name'] kw.pop('name') x
Images in accelerated memory are much faster to draw on the screen. This example demonstrates how to take an image and make an accelerated copy of it and then use it to draw on the screen. The problem with images in accelerated memory is that they ca
模式识别的一个实验,要求画出贝叶斯决策的图.这里我是利用python中的matplotlib库实现的图线的拟合.主要对于matplotlib的使用可以参照博客:webary 如果要绘制三维图像可以参考博客:python绘制三维图 具体实现: 接下来,就是对具体数据进行绘图了.比如我们要绘制一条y=x^2的曲线,可这样写代码: x = range() # 横轴的数据 y = [i*i for i in x] # 纵轴的数据 pl.plot(x, y) # 调用pylab的plot函数绘制曲线 pl
