使用BokehJS条形图重叠条形图

import { Bar } from "@bokehjs/models";
import { show, output_file } from "@bokehjs/api";

const data = {
  categories: ["Category 1", "Category 2", "Category 3"],
  dataset1: [10, 20, 30],
  dataset2: [15, 25, 35]
};

const bar = new Bar({
  x: data.categories,
  y: [data.dataset1, data.dataset2],
  width: 0.5,
  fill_color: ["red", "blue"]
});

const plot = new Plot({
  title: "Overlapping Bar Chart",
  x_range: data.categories,
  y_range: [0, Math.max(...data.dataset1, ...data.dataset2)],
  toolbar_location: "above"
});
plot.add_glyph(bar);

output_file("bar_chart.html");
show(plot);
