python - Python圆形条形图中心太小

Question

谁能帮我弄清楚如何使中间的圆圈变大，这样我的酒吧就不会全部挤在一起？？？我真的试图调整 plt.figure(figsize=(15,30)) 中的大小，但它只会使最高的条变得更高，而没有改变中间圆（空心部分）的任何内容。

：我得到的图像看起来像这样

我希望得到这样的输出：

我的代码：

#plot firm_x_sales by cat_code and fund_category



# remove grid
plt.axis('off')

# Set the coordinates limits
upperLimit = 100
lowerLimit = 30

# Compute max and min in the dataset
max = df8['firm_x_sales'].max()

# Let's compute heights: they are a conversion of each item value in those new coordinates
# In our example, 0 in the dataset will be converted to the lowerLimit (10)
# The maximum will be converted to the upperLimit (100)
slope = (max - lowerLimit) / max
heights = slope * df8.firm_x_sales + lowerLimit 

# Compute the width of each bar. In total we have 2*Pi = 360°
width = 2*np.pi / len(df8.index)

# Compute the angle each bar is centered on:
indexes = list(range(1, len(df8.index)+1))
angles = [element * width for element in indexes]
angles


# initialize the figure
plt.figure(figsize=(20,20))
ax = plt.subplot(111, polar=True)
plt.axis('off')

# Draw bars
bars = ax.bar(
    x=angles, 
    height=heights, 
    width=width, 
    bottom=lowerLimit,
    linewidth=2, 
    edgecolor="white",
    color="#61a4b2",
)


# little space between the bar and the label
labelPadding = 10

# Add labels
for bar, angle, height, label in zip(bars,angles, heights, df8["fund_category"]):

    # Labels are rotated. Rotation must be specified in degrees :(
    rotation = np.rad2deg(angle)

    # Flip some labels upside down
    alignment = ""
    if angle >= np.pi/2 and angle < 3*np.pi/2:
        alignment = "right"
        rotation = rotation + 180
    else: 
        alignment = "left"

    # Finally add the labels
    ax.text(
        x=angle, 
        y=lowerLimit + bar.get_height() + labelPadding, 
        s=label, 
        ha=alignment, 
        va='center', 
        rotation=rotation, 
        rotation_mode="anchor",
        fontsize=5)
