datascience.tables.Table.plot

Table.plot(column_for_xticks=None, select=None, overlay=True, width=None, height=None, **vargs)

Plot line charts for the table. Redirects to Table#iplot for plotly charts if interactive plots are enabled with Table#interactive_plots

Args:

column_for_xticks (str/array): A column containing x-axis labels

Kwargs:

overlay (bool): create a chart with one color per data column;

if False, each plot will be displayed separately.

show (bool): whether to show the figure if using interactive plots; if false, the figure

is returned instead

vargs: Additional arguments that get passed into plt.plot.

See http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.plot for additional arguments that can be passed into vargs.

Raises:

ValueError – Every selected column must be numerical.

Returns:

Returns a line plot (connected scatter). Each plot is labeled using the values in column_for_xticks and one plot is produced for all other columns in self (or for the columns designated by select).
