WIF Trend wif_trend¶
Wafer Trend Charts by Flash Field For Single Variable
WIF Trend gives you a clear view of within flash field & field to field tendency and distribution. Anormal waving or mountain shape pattern and shot-jump pattern could be easily spotted with this chart. Blue line is median trend by default which is less impacted by outliers, and orange area indicates the major distribution at the same WIF_COL.
from wfmap.data import load_data
from wfmap import wif_trend
data = load_data()
fig = wif_trend(data, 'MR')
The size of orange area is determined by majority, which means the center percentage of the whole distribution. To achieve similar quantile as boxplot could set majority=50.
fig2 = wif_trend(data, 'MR', majority=50)
