python - Hvplot：如何删除默认工具

Question

我正在使用 HvPlot，它运行良好，但我不知道如何删除默认工具“pan”、“wheel_zoom”和“box_zoom”。我的 HvPlot 代码是：

points = df.hvplot.line(x='x', y='y',
                        grid=True,
                        tools=['xpan',          # move along x
                               'xwheel_pan',    # move along x with wheel
                               'xwheel_zoom',   # zoom on x with wheel
                               'xzoom_in',      # zoom in on x
                               'xzoom_out',     # zoom out on x
                               'crosshair',     # show where the mouse is on axis
                               'xbox_zoom',     # zoom on selection along x
                               'undo',          # undo action
                               'redo'],         # redo action
                        width=1200, height=550,
                        aggregator='any',
                        datashade=True)

我有这个数字：

Answer 1

您可以使用.opts(default_tools=[])摆脱默认工具：

示例代码：

import numpy as np
import pandas as pd

import hvplot.pandas

df = pd.DataFrame({
    'x': np.random.normal(size=50),
    'y': np.random.normal(size=50),
})

scatter_plot = df.hvplot.scatter(
    x='x', y='y', 
    tools=['tap','box_select'])

# manually specifying the default tools gets rid of any preset default tools
# you also just use an empty list here
scatter_plot.opts(default_tools=['wheel_zoom'])
