Can some one help me. I want to make a contour plot let's say an example of my data below. I have height data and temperatur data in csv file for 4 day :
Output:date 1 date 2 date 3 date 4
height temp height temp height temp height temp
9.3 28.0 8.7 27.6 10.0 26.0 9.5 26.8
9.7 27.3 9.3 26.8 12.8 25.5 10.8 25.9
10.0 26.8 10.8 25.9 13.1 25.3 11.4 25.0
10.6 26.5 12.7 24.4 14.8 24.7 12.9 24.2
12.8 26.0 13.5 23.8 15.2 24.3 13.6 23.4
13.3 25.7 17.8 22.7 16.8 23.7 14.0 22.6
16.8 25.4 18.9 22.4 17.9 23.3 14.7 22.0
17.2 24.6 20.0 21.0 18.6 23.0 15.9 21.3
And this is my script tried :import pandas as pd import matplotlib.pyplot as plt import numpy as np import matplotlib.colors as colors import csv import glob import os path = "C:/Users/SYIFAAZRA/Documents/belajar_wradlib/Skew-T/New/" os.chdir(path) filenames = glob.glob("*.csv") dfs = [] for f in filenames: col_names = ['height', 'temp'] df = pd.read_csv(f, delimiter=',',skiprows=7, usecols=[11, 21], names=col_names, na_values=['----']) df = df.dropna() max = df.height.idxmax() min = df.height.idxmin() df = df.loc[min:max, :] dfs.append(df) df2 = pd.concat(dfs, ignore_index=False, axis=1) fig = plt.figure() ax = fig.add_subplot(111) x = np.linspace(0,100, 50) y = df['height'] X,Y = np.meshgrid(x, y) Z = df['temp'] plt.show()I want to make a contour plot which x= number of date, y=height data, z=temp data. Can someone suggest to me how to resolve my script above.
