I have a function in which returns scatterplot of a Isomap
<https://en.wikipedia.org/wiki/Isomap>function, which takes output from a
TF-IDF <https://en.wikipedia.org/wiki/Tf%E2%80%93idf> function, which
calculated TF-IDF values of certain articles online. I used four articles
and I want to show the 4 articles by a 3D scatterplot.
Below is the function to turn my Isomap values to a 3D scatterplot :
def Isomap(tfidf):
jon = pd.read_csv(tfidf)
le = preprocessing.LabelEncoder()
tims = jon.apply(le.fit_transform)
iso = manifold.Isomap(n_neighbors=2, n_components=3)
john = iso.fit_transform(tims)
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
use_colors = 'rybg'
ax.scatter(john[:,0], john[:,1],john[:,2],color=use_colors,alpha=.5) #
x,y,z coord. jon 1-3
plt.title('Isomap of candiates')
plt.xlabel('x')
plt.ylabel('y')
plt.show()
plt.savefig('isomap.png')
The problem is that I usually only get one color returned. And even if I
get the code to print out 4 colors, I'm not sure how to get those colors
to correspond to the four web articles.
Thanks for the help in advance.
