要利用Bokeh制作堆叠条形图,首先需要安装Bokeh库。然后可以按照以下步骤进行操作:
导入必要的库和模块:from bokeh.io import output_file, showfrom bokeh.plotting import figurefrom bokeh.models import ColumnDataSource创建数据源:data = { 'categories': ['A', 'B', 'C'], 'values1': [10, 20, 30], 'values2': [15, 25, 35]}source = ColumnDataSource(data=data)创建绘图对象:p = figure(x_range=data['categories'], plot_height=350, title='Stacked Bar Chart', toolbar_location=None, tools="")绘制堆叠条形图:p.vbar(x='categories', top='values1', width=0.5, source=source, color='blue', legend_label='Values1')p.vbar(x='categories', top='values2', width=0.5, source=source, color='red', legend_label='Values2')设置绘图属性:p.y_range.start = 0p.xgrid.grid_line_color = Nonep.axis.minor_tick_line_color = Nonep.outline_line_color = Nonep.legend.location = "top_left"p.legend.orientation = "horizontal"输出和展示绘图:output_file("stacked_bar_chart.html")show(p)通过以上步骤,您可以利用Bokeh轻松制作堆叠条形图,并将其保存为HTML文件展示出来。
