The following example plots data from a Deephaven table.
from deephaven.plot.figure import Figure
from deephaven.column import int_col
from deephaven import new_table
source = new_table([int_col("Keys", [3, 2, 2, 1, 1, 1])])
new_plot = (
Figure()
.plot_cat_hist(series_name="Keys count", t=source, category="Keys")
.chart_title(title="Count of Each Key")
.show()
)
