                                'Percentage': lambda z: 100 * z.size / len(df),

                    st.dataframe("Length distribution:", out1)
                    st.write("Width distribution:", out2)
                    st.write("Height distribution:", out3)

with this code, I distributed the data in three different integer columns dynamically. But now i want to create histogram from the data.
How is this possible in streamlite?

Hi @hemanth_vema ,

Yes it is, I have created and plotted many Matplotlib charts in Streamlit and the key is to use ‘st.pyplot(fig)’ in the end, as the code below got from the Streamlit documentation (st.pyplot - Streamlit Docs).

import matplotlib.pyplot as plt
import numpy as np

arr = np.random.normal(1, 1, size=100)
fig, ax = plt.subplots()
ax.hist(arr, bins=20)

st.pyplot(fig)
