4. Create bar labels/annotations Since we’re creating a Python bar graph with labels, we need to define label values and label position. To label bars with values, we’ll use the following function: # Create labels rects = ax.patches for rect in rects: # Get X and Y placement ...
plt.show() 2. 带边界的气泡图(Bubble plot with Encircling) 有时,您希望在边界内显示一组点以强调其重要性。 在这个例子中,你从数据框中获取记录,并用下面代码中描述的 encircle() 来使边界显示出来。 frommatplotlibimportpatchesfromscipy.spatialimportConvexHullimportwarnings; warnings.simplefilter('ignore')...
help(plt.Axes.bar) 5.2 线条属性 matplotlib绘图方法中线条的基本属性和对应关键词参数 / 在实际应用中,不同颜色、宽度和线型的线条是提高图形可读性的重要工具。线宽可用于强调线条的重要性。下面的示例绘制了函数s i n ( x ) sin(x)sin(x)及其在x = 0 x=0x=0处级数展开后的图形。
