如何在 Plotly Animation 滑块中设置小数位数 - Python

Question

我正在将 Dataframe 绘制到 Plotly Express 动画中。 Slider使用的是'shot'号，都是整数（没有小数位）。当 Slider 显示时，它有小数位，如何删除它们？来自数据框的样本。

shot    Easting Northing    Depth
1001    455951.7    7328194.4   2.5
1002    455301.6    7326908.9   2.5
1003    455327.8    7326897.2   2.5
1004    455880.7    7328069.7   2.5
1005    455875.3    7328058.5   2.5
1006    455869.8    7328047.2   2.5
1007    455864.3    7328036.0   2.5
1008    455858.8    7328024.8   2.5
1009    455853.3    7328013.6   2.5
1010    455847.8    7328002.3   2.6
1011    455842.3    7327991.1   2.6
1012    455836.8    7327979.9   2.6
1013    455831.3    7327968.7   2.6
1014    455825.8    7327957.4   2.6
1015    455820.3    7327946.2   2.6
1016    455814.8    7327935.0   2.6
1017    455809.3    7327923.8   2.6
1018    455803.8    7327912.6   2.6
1019    455798.3    7327901.4   2.6

代码。我把数据称为 dfAnime

        ## Animated plot
        import plotly.express as px
        fig = px.scatter(dfAnime, x="Easting", y="Northing", animation_frame="shot",
            color='Depth',range_x=[np.min(dfAnime['Easting']),np.max(dfAnime['Easting'])],
            range_y=[np.min(dfAnime['Northing']),np.max(dfAnime['Northing'])])
            
        fig.layout.updatemenus[0].buttons[0].args[1]["frame"]["duration"]=100 # Sets speed. Comment out to turn off play/stop button
        fig.update_yaxes(
            scaleanchor="x",
            scaleratio=1,
            exponentformat='none')
        fig.update_xaxes(
            scaleanchor="x",
            scaleratio=1,
            exponentformat='none')
        fig.update_layout(template="plotly_dark")           
        #fig.show()

Answer 1

答案是数据类型，它应该是 Int 而不是 float（从父数据帧继承而来）。
以下内容来自 Plotly 社区论坛上发布的同一问题。

The labels should indeed be an integer if the shot column was an integer in the same dataframe.

Could you check the data type of the column using dfAnime.dtypes?

If it is not int64, then you can change the column to int64 using this command dfAnime.shot = dfAnime.shot.astype(int)

I am thinking that the datatype is not int64, maybe object or float64 which might be causing this error.
