[英]Grouped Bar graph Pandas
我在一个名为df
DataFrame
有一个表:
+--- -----+------------+-------------+----------+------------+-----------+
|avg_views| avg_orders | max_views |max_orders| min_views |min_orders |
+---------+------------+-------------+----------+------------+-----------+
| 23 | 123 | 135 | 500 | 3 | 1 |
+---------+------------+-------------+----------+------------+-----------+
我现在正在寻找的是绘制一个分组条形图,它在一个条形图中向我显示(平均、最大、最小)视图和订单。
即在 x 轴上,视图和订单将被分开的距离和 3 条(平均、最大值、最小值)用于视图和类似的订单。
我附上了一个示例条形图图像,只是为了了解条形图的外观。
我从在 matplotlib 中设置分组条形图之间的间距中获取了以下代码,但它对我不起作用:
plt.figure(figsize=(13, 7), dpi=300)
groups = [[23, 135, 3], [123, 500, 1]]
group_labels = ['views', 'orders']
num_items = len(group_labels)
ind = np.arange(num_items)
margin = 0.05
width = (1. - 2. * margin) / num_items
s = plt.subplot(1, 1, 1)
for num, vals in enumerate(groups):
print 'plotting: ', vals
# The position of the xdata must be calculated for each of the two data
# series.
xdata = ind + margin + (num * width)
# Removing the "align=center" feature will left align graphs, which is
# what this method of calculating positions assumes.
gene_rects = plt.bar(xdata, vals, width)
s.set_xticks(ind + 0.5)
s.set_xticklabels(group_labels)
绘图:[23, 135, 3] ... ValueError:形状不匹配:对象不能广播到单个形状
您不必为了以某种方式绘制它而修改您的数据框,对吗?
使用seaborn!
import seaborn as sns
sns.catplot(x = "x", # x variable name
y = "y", # y variable name
hue = "type", # group variable name
data = df, # dataframe to plot
kind = "bar")
