Prevent from creating dataframe

Hello I have problem:

I want my app to just print some charts, based on some dataframe (named “big_board”), after clicking button (named “draw_charts_button”).

draw_charts_button = st.sidebar.button("draw charts")

if draw_charts_button:

      big_board = load_big_board()

and then there is some code from printing charts. But at the top of the page i’m getting big_board dataframe widget, which I don’t need. What should I do to get rid of it?
