使用plotly绘制一个散点图，利用数据可视化的概念来观察 "预算 "与 "毛值 "之间的关系。

Question

用plotly绘制一个散点图，看看不同类型的 "预算 "与 "总价值 "之间的关系。

定制的子任务----

子任务1.1--尝试自定义您的散点图，添加边际图，如直方图、方块图或小提琴图子任务1.2--尝试链接悬停数据，并尝试探索动态选择流派的选项。

我的错误代码。

#Sub task 1.1 marginal plots with an histogram
movies = px.data.iris()
fig = px.scatter(movies, x="budget", y="Gross", color="genre_1", marginal_y="rug", marginal_x="histogram")
fig

请帮忙 谢谢，SB

您正在做的是，您正在加载一个新的散点图。iris 数据框架。

movies = px.data.iris()

但是，没有名为 "budget", "Gross" 就像错误信息所说的那样，你必须加载一个适当的数据框架，其中包含那些列--你的数据。你必须加载一个适当的数据框架，其中包含这些列--你的数据。

movies = your_data_frame
