如何使用货币格式化散景 xaxis 刻度

我正在使用 jupyter 笔记本制作子弹图来比较两个值。该图已渲染，但我想格式化 x 轴刻度以显示货币。 这就是我到目前为止所拥有的......

project = "Rocket"
targetspend = 15000
spend2date = 16600
data = [(project, targetspend, spend2date)]

from bokeh.io import show, output_notebook
from bokeh.plotting import figure

def make_bokeh_spend_bullet(data):
  output_notebook()
  if len(data) ==1:
      ph = 135

  elif len(data) >1 and len(data) < 3:
    ph =165
  else:
    ph = ( 6 * len(data) * 10)


  if data[0][2] < data[0][1] * 2:
    perf = data[0][2]
    limits = [0, data[0][1], data[0][1] *2]
  else:
    perf = data[0][2]
    limits = [0, data[0][1], data[0][2]]

  labels = ["OK", "Over budget", ]
  cats = [x[0] for x in data]

  p=figure(title="Project Spend", plot_height=ph, plot_width=600, y_range=cats)
  p.x_range.range_padding = 0
  p.grid.grid_line_color = None
  p.xaxis[0].ticker.num_minor_ticks = 0
  #p.xaxis[0].ticker.format('$0,0')

  for left, right, color in zip(limits[:-1], limits[1:], OrRd3[::-1]):
    p.hbar(y=cats, left=left, right=right, height=0.8, color=color)


  for x in data:
    if x[2] > x[1]:
      p.hbar(y=cats, left=0, right=perf, height=0.3, color="firebrick")
    else:
      p.hbar(y=cats, left=0, right=perf, height=0.3, color="gray")

  comp = [x[1] for x in data]
  p.segment(x0=comp, y0=[(x, -0.5) for x in cats], x1=comp,
          y1=[(x, 0.5) for x in cats], color="black", line_width=2)

  for start, label in zip(limits[:-1], labels):
    p.add_layout(Label(x=start, y=0, text=label, text_font_size="10pt",
                       text_color='black', y_offset=5, x_offset=15)) 
  return show(p)

output_notebook()

p = make_bokeh_spend_bullet(data)

我读自散景文档 https://bokeh.pydata.org/en/latest/docs/reference/models/formatters.html关于类 NumeralTickFormatter(**kwargs) 但不清楚如何为我的图表使用此格式选项。

不管你信不信，但这似乎只适用于美元货币。我无法让它与欧洲货币符号一起使用。有什么特别的技巧吗？

例如，以下代码正在运行：

    plot.handles['yaxis'].formatter = NumeralTickFormatter(format="0,0 $")

虽然这个不产生任何货币符号：

    plot.handles['yaxis'].formatter = NumeralTickFormatter(format="0,0 €")
