Small multiples

Introductie tot datavisualisatie met Matplotlib

Data Scientist

Data toevoegen

ax.plot(seattle_weather["MONTH"], 
        seattle_weather["MLY-PRCP-NORMAL"], 
        color='b')
ax.set_xlabel("Tijd (maanden)")
ax.set_ylabel("Neerslag (inch)")
plt.show()

Meer data toevoegen

ax.plot(seattle_weather["MONTH"], seattle_weather["MLY-PRCP-25PCTL"], 
        linestyle='--', color='b')
ax.plot(seattle_weather["MONTH"], seattle_weather["MLY-PRCP-75PCTL"], 
        linestyle='--', color=color)
plt.show()

En nog meer data

ax.plot(austin_weather["MONTH"], austin_weather["MLY-PRCP-NORMAL"],
        color='r')
ax.plot(austin_weather["MONTH"], austin_weather["MLY-PRCP-25PCTL"], 
        linestyle='--', color='r')
ax.plot(austin_weather["MONTH"], austin_weather["MLY-PRCP-75PCTL"], 
        linestyle='--', color='r')
plt.show()

Te veel data!

Small multiples met plt.subplots

fig, ax = plt.subplots()

fig, ax = plt.subplots(3, 2)

plt.show()

Data toevoegen aan subplotten

ax.shape

(3, 2)

ax[0, 0].plot(seattle_weather["MONTH"], 
              seattle_weather["MLY-PRCP-NORMAL"], 
              color='b')

plt.show()

Subplotten met data

fig, ax = plt.subplots(2, 1)

ax[0].plot(seattle_weather["MONTH"], seattle_weather["MLY-PRCP-NORMAL"], 
           color='b')
ax[0].plot(seattle_weather["MONTH"], seattle_weather["MLY-PRCP-25PCTL"], 
           linestyle='--', color='b')
ax[0].plot(seattle_weather["MONTH"], seattle_weather["MLY-PRCP-75PCTL"], 
           linestyle='--', color='b')

ax[1].plot(austin_weather["MONTH"], austin_weather["MLY-PRCP-NORMAL"],
           color='r')
ax[1].plot(austin_weather["MONTH"], austin_weather["MLY-PRCP-25PCTL"], 
           linestyle='--', color='r')
ax[1].plot(austin_weather["MONTH"], austin_weather["MLY-PRCP-75PCTL"], 
           linestyle='--', color='r')

ax[0].set_ylabel("Neerslag (inch)")
ax[1].set_ylabel("Neerslag (inch)")

ax[1].set_xlabel("Tijd (maanden)")

plt.show()

Subplotten met data

y-as bereik delen

fig, ax = plt.subplots(2, 1, sharey=True)

Oefen met subplotten maken!
