How can I change the bar style?

loc_frame = st.selectbox("by region/by sub region/by country", ("Region", "SubRegion", "Country"))
whole_values = my_sz.groupby(loc_frame)[['quantity']].sum() = 'index'
st.bar_chart(whole_values, use_container_width = True)

I want to make above bar graph thinner than that…
How can I chage the size of the bar? and color too!
