12-Python : Plotting Multiple Bar Chart

 Assalam wbt. Jumpa lagi.

Post ke-11 yang lalu kita telah belajar bagaimana untuk setting banyak plot dalam satu frame. Post kali ini kita akan cuba untuk plot beberapa carta bar seperti yang dibincangkan di post ke-10 menggunakan data2.dat.

import matplotlib.pyplot as plt

import numpy as np

fname='data2.dat'

data1=np.loadtxt(fname,skiprows=1)

data1[data1<0.0]=0.0

data1[data1==0.01]=0.0

data1[np.isnan(data1)]=0.0

station1=data1[:,0]

station1=station1.astype(int) 

lat1=data1[:,1]

lon1=data1[:,2]

rain1=data1[:,3]

rain2=data1[:,4]

rain3=data1[:,5]

N = 17  ## total bar

ind = np.arange(N)  

width = 0.95       # the width of the bars

color1='red' 

color2='blue'

color3='green'

## SETTING PLOT AREA 3 IMAGES IN (1x3) ###

fig = plt.figure(figsize=(11,5)) 

plt.subplot(1,3,1)

plt.bar(ind, rain1, width, color=color1, tick_label = station1,

        edgecolor="black",linewidth=0.5)

plt.xticks(rotation=90)

plt.xlabel('Meteorological Stations')

plt.ylabel('Hourly Rainfall (mm)')

plt.title('Rain 1')

plt.subplot(1,3,2)

plt.bar(ind, rain2, width, color=color2, tick_label = station1,

        edgecolor="black",linewidth=0.5)

plt.xticks(rotation=90)

plt.xlabel('Meteorological Stations')

plt.ylabel('Hourly Rainfall (mm)')

plt.title('Rain 2')

plt.subplot(1,3,3)

plt.bar(ind, rain3, width, color=color3, tick_label = station1,

        edgecolor="black",linewidth=0.5)

plt.xticks(rotation=90)

plt.xlabel('Meteorological Stations')

plt.ylabel('Hourly Rainfall(mm)')

plt.title('Rain 3')
