I am stuck off a point about updating plotly Scatter3d. I have a bunch of x, y, and z value of a dataframe. Firstly, User loads first dataframe file. Figure plots the first dataframe as you can see
Then, user loads second dataframe. However, there are two graphs. Second dataframe does not plotted on first graph. Its create second graph. 
there are two graph same time. 
How can update the graph using Figure 1?.
