有没有办法扭转热图中y轴的顺序 [英] Is there a way to reverse the order of the y axis in heatmap of plotly

问题描述

所以我有

hours = [x for x in range(7,18)]
columns = [1, 2, 3, 4, 5]

    matrixDatos = [[0,1,0,1,0],
                   [0,1,0,1,1],
                   [2,3,2,3,2],
                   [2,3,2,3,3],
                   [4,5,4,5,4],
                   [4,5,4,5,5],
                   [6,7,6,7,6],
                   [6,7,6,7,7],
                   [8,9,8,9,8],
                   [8,9,8,9,8]
                    ]



    table = ff.create_table(matrixDatos)

    fig = ff.create_annotated_heatmap(matrixDatos, x=columns, y=hours, colorscale='Viridis')

但是它会打印y轴从18到7的热图，有没有办法从7到18来打印热图?

But it prints the heatmap with the y axis from 18 to 7 is there a way to print it from 7 to 18?

推荐答案

您好，我尝试了提供的代码，但收到一条错误消息，说Y轴(小时)数不等于Z轴数(matrixDatos) ).因此，为了使代码正常工作，我将范围从7减小到16.

Hi I tried the code provided, I was getting an error saying that number of Y-axis (hours) does not equal the number of Z-axis (matrixDatos). So I reduced the range from 7 to 16 for the code to work.

我在布局对象中使用了 xaxis对象的自动调整范围" 参数，为了反转该轴，我们需要使用 反向" 参数.

I used the "autorange" parameter of the xaxis object in layout object, to reverse the axis we need to use "reversed" parameter.

原始代码(有问题)输出: 代码更改:

hours = [x for x in range(7,17)]
columns = [1, 2, 3, 4, 5]

matrixDatos = [[0,1,0,1,0],
               [0,1,0,1,1],
               [2,3,2,3,2],
               [2,3,2,3,3],
               [4,5,4,5,4],
               [4,5,4,5,5],
               [6,7,6,7,6],
               [6,7,6,7,7],
               [8,9,8,9,8],
               [8,9,8,9,8]
                ]



table = ff.create_table(matrixDatos)

fig = ff.create_annotated_heatmap(matrixDatos, x=columns, y=hours, colorscale='Viridis')
fig['layout']['yaxis']['autorange'] = "reversed"
iplot(fig)

代码更改输出:

我希望这是您所需要的.

I hope this is what you need.
