我正在做一些粒子追踪。因此,我想绘制通过粒子的分布和累积函数。
当我绘制分布图时,我的情节总是从一个步骤开始到早期。 有没有办法将事件绘制为一种峰值,而不在x轴上进行任何插值?
附上简短的示例数据......
time = [ 0.,1.,2.,3.,4.,5.,6.,7.,8.,9.]
counts = [0,0,1,0,2,0,0,0,1,0]
cum = [ 0.,0.,0.25,0.25,0.75,0.75,0.75,0.75,1.,1.]
ax1 = plt.subplot2grid((1,2), (0, 0), colspan=1)
ax1.plot(time, counts, "-", label="Density")
ax1.set_xlim([0,time[-1]])
ax1.legend(loc = "upper left", frameon = False)
ax1.grid()
ax2 = plt.subplot2grid((1,2), (0, 1), rowspan=1)
ax2.step(time, cum, "r",where='post', label="Sum")
ax2.legend(loc = "upper left", frameon = False)
ax2.set_ylim([-0.05,1.05])
ax2.set_xlim([0,time[-1]])
ax2.grid()
plt.suptitle("Particle distribution \n")
plt.show()
感谢您的帮助!
