9,316 PointsThis is not working on my local instance of python - please help.
Here is my code:
from s6v1 import *
import matplotlib.pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages
def plot_minimal_graph(tally, columns, *args):
plt.style.use("bmh")
fig = plt.figure(dpi = 200)
colors = plt.rcParams['axes.color_cycle']
#-- white background to use less printer ink---#
ax = plt.subplot(111, axisbg = 'white')
# Plot bars and create text labels for the table
for priceBucket in tally:
ax.bar(priceBucket, tally[priceBucket], color = colors[priceBucket%len(tally)])
ax.annotate(r"%d" % (tally[priceBucket]),
(priceBucket+0.2, tally[priceBucket]),
va = "bottom", ha="center")
# Include a legend
ax.legend(columns)
# Remove distrating lines on top, left and right
ax.spines['top'].set_visible(False)
ax.spines['right'].set_visible(False)
ax.spines['left'].set_visible(False)
# Remove distracting tick marks
ax.yaxis.set_ticks_position('none')
ax.xaxis.set_ticks_position('none')
# Add chart titel and axes labels
plt.xlabel("Tie Price", fontsize = 13)
plt.ylabel("Number of Ties", fontsize = 13)
plt.title("Chart #1")
#Add labels to bars along x axes
x = range(1, len(tally) + 1)
plt.xticks(x, columns, rotation = "horizontal", ha = "left")
return fig
def plot_graph_with_table(cell_text, row_text, columns):
plt.style.use("ggplot")
fig = plt.figure()
# Include table
ax2 = fig.add_subplot(111)
ax2.axis("off")
the_table = ax2.table(cellText= cell_text,
rowLabels = row_text,
colLabels = columns,
loc = 'center right')
pp = PdfPages("my_report.pdf")
plot1 = plot_minimal_graph(price_groups, columns)
pp.savefig(plot1, bbox_inches = 'tight')
table_text = build_table_text(brand_and_price_data, brands)
plot2 = plot_graph_with_table(table_text[0], table_text[1], columns)
pp.savefig(plot2, bbox_inches = 'tight')
pp.close()
when I run it, I get the following exception:
Traceback (most recent call last):
File ".\s6v2.py", line 69, in <module>
plot2 = plot_graph_with_table(table_text[0], table_text[1], columns)
File ".\s6v2.py", line 61, in plot_graph_with_table
loc = 'center right')
File "C:\...\Continuum\Anaconda3\lib\site-packages\matplotlib\axes\_axes.py", line 5372, in table
return mtable.table(self, **kwargs)
File "C:\...\Continuum\Anaconda3\lib\site-packages\matplotlib\table.py", line 483, in table
cols = len(cellText[0])
IndexError: list index out of range
any advice? Thanks!
[MOD: added ```python and ```bash formatting around the code blocks -cf]

9,316 PointsHi Chris Thanks for your advice. Here is the result:
>>> print(table_text[0], table_text[1], columns)
[] [] ['$0-50', '$50-100', '$100-150', '$150-200', '$200-250', '$250+']
followed by the same "IndexError: list index out of range" exception.
I'm thinking this is yet another drawback to running python on Windows. It is frustrating.

Treehouse Moderator 68,423 PointsThat's progress. Now we just need to figure out why text_table[0] is empty [ ].

Treehouse Moderator 68,423 PointsRewatching the styling video, at 2:28, Kat seems to have the exact same error. She comments out a line, in s5v3.py.
# s5v3.py
# create_table(brand_and_price_data, price_groups, brands, columns, "_charts/s5_prices_in_table.png")

9,316 PointsHi Chris Thanks for your help. I went back to s5v3.py and commented out the line you indicated, then ran "python s6v2.py"
the exception is the same:
Traceback (most recent call last):
File "s6v2.py", line 69, in <module>
plot2 = plot_graph_with_table(table_text[0], table_text[1], columns)
File "s6v2.py", line 61, in plot_graph_with_table
loc = 'center right')

able
return mtable.table(self, **kwargs)
File "C:\Users\-----\AppData\Local\Continuum\Anaconda3\lib\site-packages\matplotlib\table.py", line 483, in table
cols = len(cellText[0])
IndexError: list index out of range
going to try your first suggestion now.

Treehouse Moderator 68,423 PointsI think something in the creation of table_text using build_table_text is at issue. When I run your code I get a PDF. When I run it interactively, I get values for table_text. (note: I added extra empty comment lines to run in interactive shell with cut-and-paste)

Treehouse Moderator 68,423 PointsSince your comment above showing the result:
>>> print(table_text[0], table_text[1], columns)
[] [] ['$0-50', '$50-100', '$100-150', '$150-200', '$200-250', '$250+']
I would suggest walking back through the code looking at where the data is missing.. brand_and_price_data is created in s5v3.py:
brand_and_price_data = open_with_csv("_data/tempTableFile.csv", d=',')
Check if this has real data. Perhaps the CSV file contains bad data.

Treehouse Moderator 68,423 PointsChris Freeman
Treehouse Moderator 68,423 PointsI don't see an obvious error. The "index out of range" on a
len()statement suggests that the data is missing orNone. I suggest using print to inspecttable_text[0],table_text[1], andcolumns.
