Need scrollbar when having many data in a boxplot to go over the data smooth

In a boxplot, the user can have a lot of data. It is hard to visualize anything if all the data is shown. Instead, we can show several boxes when the plot renders, but the user needs to see the rest of the data (box by box, not all in one view). A horizontal scroll bar is ideal, because using the mouse to move the view will unintentionally change the vertical axis view and the purpose would be to visualize how the boxes differ in height and position on vertical axis.

未指定檔案或測試。先找出 plotly.js 中 boxplot 的繪製與互動進入點，接著檢查水平與垂直導覽的處理方式。完成的標準是使用者可以水平捲動瀏覽各個箱體，同時保留垂直軸檢視。
