今天我们再来讲解一下Python使用Plotly绘图工具如何绘制直方图 使用plotly绘制直方图需要用到graph_objs包中的Histogram函数 我们将数据赋值给函数中的x变量,x = data 即可绘制出直方图如果将数据赋值给y变量, 则会,绘制出水平直方图。 下面我们来看个基本例子 运行上诉代码,我们可以得到一个如上图所示的基本直方图 数据...
我想知道如何在一些对象属性上运行help()来获得更多信息。我想使用作为go.Box模块一部分的plotly.graph_objs.graph_objs类来创建一个图形,但是我没有多少关于go.Box对象和属性的信息。'<box-object>' is the object at [] File: c:\python27\lib\site-packages\plotly</e...
importplotly.graph_objectsasgo #createdummydata vals=np.ceil(100*np.random.rand(5)).astype(int) keys=["A","B","C","D","E"] 我们基于所生成的假数据来绘制柱状图,代码如下: fig=go.Figure() fig.add_trace( go.Bar(x=keys,y=vals) ...
Figure 4: A histogram created using Plotly Graph Objects. Plotly express functions internally make calls to graph_objects, which returns a value. Therefore, Plotly express functions are useful because they enable users to draw data visualizations that would typically take more lines of code if the...
