Data set Shape → (220320, 55) but I am plot only 5 variables.
import streamlit as st
import pandas as pd

df=pd.read_csv("D:\\KSR\\Madu\\sensor.csv")


df.head()





#set 1(plots of sensors 4,6,7,8,9 are correlated)

df1=pd.DataFrame(df,columns=['Operation','sensor_04','sensor_06','sensor_07','sensor_08','sensor_09'])

st.write("""
# sensors temperatures

## shown are various sensor Temperratures 

""")
    
          
# sensors min max temperatures
         
st.line_chart(df1.sensor_04)
st.line_chart(df1.sensor_06)
st.line_chart(df1.sensor_07)
st.line_chart(df1.sensor_08)
st.line_chart(df1.sensor_09)
