我跟着這裏的指導:Python的和絃圖(Plotly) - 交互式工具提示
https://plot.ly/python/filled-chord-diagram/
我生成此:
在引導,我跟着ribbon_info
代碼將hoverinfo添加到連接的色帶,但沒有顯示。我可以得到hoverinfo只顯示功能區結束。任何人都可以看到我要去哪裏嗎?是
ribbon_info=[]
for k in range(L):
sigma=idx_sort[k]
sigma_inv=invPerm(sigma)
for j in range(k, L):
if matrix[k][j]==0 and matrix[j][k]==0: continue
eta=idx_sort[j]
eta_inv=invPerm(eta)
l=ribbon_ends[k][sigma_inv[j]]
if j==k:
layout['shapes'].append(make_self_rel(l, 'rgb(175,175,175)' ,
ideo_colors[k], radius=radii_sribb[k]))
z=0.9*np.exp(1j*(l[0]+l[1])/2)
#the text below will be displayed when hovering the mouse over the ribbon
text=labels[k]+' appears on'+ '{:d}'.format(matrix[k][k])+' of the same grants as '+ '',
ribbon_info.append(Scatter(x=z.real,
y=z.imag,
mode='markers',
marker=Marker(size=5, color=ideo_colors[k]),
text=text,
hoverinfo='text'
)
)
else:
r=ribbon_ends[j][eta_inv[k]]
zi=0.9*np.exp(1j*(l[0]+l[1])/2)
zf=0.9*np.exp(1j*(r[0]+r[1])/2)
#texti and textf are the strings that will be displayed when hovering the mouse
#over the two ribbon ends
texti=labels[k]+' appears on '+ '{:d}'.format(matrix[k][j])+' of the same grants as '+\
labels[j]+ '',
textf=labels[j]+' appears on '+ '{:d}'.format(matrix[j][k])+' of the same grants as '+\
labels[k]+ '',
ribbon_info.append(Scatter(x=zi.real,
y=zi.imag,
mode='markers',
marker=Marker(size=0.5, color=ribbon_color[k][j]),
text=texti,
hoverinfo='text'
)
),
ribbon_info.append(Scatter(x=zf.real,
y=zf.imag,
mode='markers',
marker=Marker(size=0.5, color=ribbon_color[k][j]),
text=textf,
hoverinfo='text'
)
)
r=(r[1], r[0])#IMPORTANT!!! Reverse these arc ends because otherwise you get
# a twisted ribbon
#append the ribbon shape
layout['shapes'].append(make_ribbon(l, r , 'rgb(255,175,175)', ribbon_color[k][j]))
爲變量的輸出如下所示:
texti = (u'Sociology appears on 79 of the same grants as Tools, technologies & methods',)
textf = (u'Tools, technologies & methods appears on 79 of the same grants as Sociology',)
ribbon_info = [{'hoverinfo': 'text',
'marker': {'color': 'rgba(214, 248, 149, 0.65)', 'size': 0.5},
'mode': 'markers',
'text': (u'Demography appears on 51 of the same grants as Social policy',),
'type': 'scatter',
'x': 0.89904409911342476,

sigma = array([ 0, 14, 12, 10, 9, 7, 8, 5, 4, 3, 2, 1, 6, 16, 13, 11, 15], dtype=int64)
先前塊後的碼構建弦圖如下:
ideograms=[]
for k in range(len(ideo_ends)):
z= make_ideogram_arc(1.1, ideo_ends[k])
zi=make_ideogram_arc(1.0, ideo_ends[k])
m=len(z)
n=len(zi)
ideograms.append(Scatter(x=z.real,
y=z.imag,
mode='lines',
line=Line(color=ideo_colors[k], shape='spline', width=0),
text=labels[k]+'<br>'+'{:d}'.format(row_sum[k]),
hoverinfo='text'
)
)
path='M '
for s in range(m):
path+=str(z.real[s])+', '+str(z.imag[s])+' L '
Zi=np.array(zi.tolist()[::-1])
for s in range(m):
path+=str(Zi.real[s])+', '+str(Zi.imag[s])+' L '
path+=str(z.real[0])+' ,'+str(z.imag[0])
layout['shapes'].append(make_ideo_shape(path,'rgb(150,150,150)' , ideo_colors[k]))
data = Data(ideograms+ribbon_info)
fig=Figure(data=data, layout=layout)
plotly.offline.iplot(fig, filename='chord-diagram-Fb')
這是唯一的hoverinfo這表明,外面的標籤,而不是稍微更多的裏面:
使用我的問題開始時的鏈接示例。他們有兩套標籤。就我的例子而言,相當於'伊莎貝爾評論了索菲亞的32個......'並沒有顯示出來。
從提供的鏈接:「ribbon_info是設置當鼠標懸停在功能區結束時顯示的信息的dicts列表。「僅僅允許hoverinfo用於標記,而不用於連接線 –
因此,當ribbon_info追加textf和texti時,它在功能區結束時顯示標籤,即'Economics'。在我的問題開始時(https://plot.ly/python/filled-chord-diagram/),他們的圖表在帶子上有標籤並且在帶子上有標籤?:/ – ScoutEU
當光標處於光標所在位置時,我的瀏覽器顯示hoverinfo在圈子的外部,但不在裏面,另外還有一些hoverinfo接近外部段,但是再次沒有內部的東西。在你的瀏覽器中刪除'class =「shapelayer」'來擺脫這些功能區,並看到底層標記它會觸發hoverinfo。 –
