Common errors

error ImportError: No module named 'vnstock_ezchart' ↓

cause Package not installed or incorrect environment.

fix

Run: pip install vnstock-ezchart

error AttributeError: 'DataFrame' object has no attribute 'bar' ↓

cause Calling chart method directly on DataFrame instead of EzChart instance.

fix

Instantiate EzChart first: chart = EzChart(df, x='x', y='y'); chart.bar()

error ValueError: x and y must be specified ↓

cause Missing required keyword arguments 'x' and 'y' when creating EzChart.

fix

Provide column names: EzChart(df, x='col1', y='col2')

Warnings

gotcha EzChart expects a pandas DataFrame; passing other iterables may raise AttributeError. ↓

fix Convert data to pandas DataFrame before passing to EzChart.

gotcha The chart.show() method blocks execution in non-interactive environments; use chart.savefig() instead. ↓

fix Use chart.savefig('output.png') to save the plot without blocking.

deprecated The old import pattern 'import ezchart' was used in pre-release versions; now it's 'vnstock_ezchart'. ↓

fix Update imports to: from vnstock_ezchart import EzChart

})

chart = EzChart(df, x='x', y='y')
