Hi,
As shown in the code below, I have a simple urth-viz-table, which displays
the content of a pandas dataframe object. I have a ipywidget button, whose
callback function, updates this dataframe object.
But even though the dataframe object is updated the urth-viz-table never
updates automatically. I have to explicitly evaluate the dataframe for the
changes to percolate.
import declarativewidgets as declwidgets
from ipywidgets import widgets # Widget definitions
from IPython.display import display # Used to display widgets in the
notebook
declwidgets.init()
import pandas as pd
df1 = pd.DataFrame([
[1, 3],
[2, 4]
], columns=["a", "b"]
)
def update_pd_df(df, data={}):
cur_b = df.loc[df.a == data.get('a', None) ,'b']
df.loc[df.a == data.get('a', None) ,'b'] = data.get('b', cur_b)
