I have a dataframe,df, which i intend to plot a line chart where we cut the window in several subplots, one per group. Then,each group contains each column which is represented by a thick line displayed on its unique subplot while the other columns are displayed discreetly like the picture below so it won't lead to a spaghetti plot. The dimension of the dataframe is (29,32)

Index        DateTimestamp              0.0      5.0     34.0 ... 31.0 

  0        2017-08-03 00:00:00           10        0      10       0

  1        2017-08-04 00:00:00           20       60    1470      20

  3        2017-08-05 00:00:00           0        58       0      24

  4        2017-08-06 00:00:00           0         0     480      24

  5        2017-09-07 00:00:00           0         0       0      25

  :                 :                     :         :       :      :

  :                 :                     :         :       :      :

the explanation of image should be something like this:

the y4, y5 .... ontop of each subplot in the picture is the particular column name being displayed which in my dataframe can be 0.0,1.0....25.0. The x-axis tick labels will be the datetimestamp column of my dataframe,df. the Y-axis is the range of values of for all columns. Here is the code:

#Initialize the figure

plt.style.use('seaborn-darkgrid')

#create a color palette

palette = plt.get_cmap('tab20')

#multiple line plot

num=0

for column in df.drop(' DateTimestamp', axis=1):

num+=1

# Find the right spot on the plot

plt.subplot(6,6, num)

# plot every groups, but discreet

for v in df.drop(' DateTimestamp', axis=1):

plt.plot(df.index, df[v], marker='', color='grey', 

linewidth=0.6, alpha=0.3)

# Plot the lineplot

plt.plot(df.index, df[column], marker='', color=palette(num), 

linewidth=2.4, alpha=0.9, label=column)

# Same limits for everybody!

plt.xlim(0,29)

plt.ylim(0,200) # the limit of the y-axis should be the max value of all possible column values 

# Not ticks everywhere

if num in range(29) :

plt.tick_params(labelbottom='off')

if num not in [1,15,28] :

plt.tick_params(labelleft='off')

# Add title

plt.title(column, loc='left', fontsize=12, fontweight=0, color=palette(num) )

#general title

plt.suptitle("Line Plot",fontsize=13, fontweight=0, color='black',style='italic', y=1.02)

#Axis title

plt.text(0.5, 0.02, 'Time', ha='center', va='center')

plt.text(0.06, 0.5, 'Number', ha='center', va='center', rotation='vertical')

However,i am getting this bad image where the figure is blurry and the x-axis is clashing between the subplots of the previous ones. Any idea what i can do to increase the resolution of line plot, each of the subplot and spacing between the previous subplots and the current one
