Button callback function placing the plots at the top of webapp

Hi everyone,

Im trying to create a sample app, I want to click a button, the function will get the values of sliders and calculate the results and plot a graph. For on_click value, i gave the function which calculates the results and plots the graph, when i click on the button, the graph is placed at the top of the page, i want it to be at the botton. Is there anyway to make sure that button on_click adds the graph at the bottom?
