Bokeh Charts¶

Bar Chart¶

bokeh.bar(y=None, data_points=None, add_interaction=True, aggregate_fn='count', width=400, height=400, step_size=None, step_size_type=<class 'int'>, title='', autoscaling=True, **library_specific_params)¶

Parameters:

x: str: x-axis column name from the gpu dataframe
y: str, default None: y-axis column name from the gpu dataframe
data_points: int, default None: when None, it means no custom number of bins are provided and data_points will default to df[self.x].nunique()
add_interaction: {True, False}, default True
aggregate_fn: {‘count’, ‘mean’}, default ‘count’
width: int, default 400
height: int, default 400
step_size: int, default 1
step_size_type: {int, float}, default int
title: str,: chart title
autoscaling: bool,: set whether chart scale is updated automatically for y_axis when data updates
x_label_map: dict, default None: label maps for x axis {value: mapped_str}
y_label_map: dict, default None: label maps for y axis {value: mapped_str}
**library_specific_params:: additional library specific keyword arguments to be passed to the function

Returns:

A bokeh chart object of type vbar

Example¶

import cudf
import cuxfilter


cux_df = cuxfilter.DataFrame.from_dataframe(cudf.DataFrame({'key': [0, 1, 2, 3, 4], 'val':[float(i + 10) for i in range(5)]}))
bar_chart_1 = cuxfilter.charts.bar('key', 'val', data_points=5, add_interaction=False)

d = cux_df.dashboard([bar_chart_1])
#view the individual bar chart part of the dashboard d
#await d.preview()
bar_chart_1.view()

Line Chart¶

bokeh.line(y=None, data_points=None, add_interaction=True, aggregate_fn='count', width=400, height=400, step_size=None, step_size_type=<class 'int'>, title='', autoscaling=True, **library_specific_params)¶

Parameters:

x: str: x-axis column name from the gpu dataframe
y: str, default None: y-axis column name from the gpu dataframe
data_points: int, default None: when None, it means no custom number of bins are provided and data_points will default to df[self.x].nunique()
add_interaction: {True, False}, default True
aggregate_fn: {‘count’, ‘mean’}, default ‘count’
width: int, default 400
height: int, default 400
step_size: int, default 1
step_size_type: {int, float}, default int
title: str,: chart title
autoscaling: bool,: set whether chart scale is updated automatically for y_axis when data updates
x_label_map: dict, default None: label maps for x axis {value: mapped_str}
y_label_map: dict, default None: label maps for y axis {value: mapped_str}
**library_specific_params:: additional library specific keyword arguments to be passed to the function

Returns:

A bokeh chart object of type line

Example¶

import cudf
import cuxfilter

cux_df = cuxfilter.DataFrame.from_dataframe(cudf.DataFrame({'key': [0, 1, 2, 3, 4], 'val':[float(i + 10) for i in range(5)]}))
line_chart_1 = cuxfilter.charts.line('key', 'val', data_points=5, add_interaction=False)

d = cux_df.dashboard([line_chart_1])
#view the individual bar chart part of the dashboard d
#await d.preview()
line_chart_1.view()
