I am working on to create figure based app, standalone application in MATLAB for plotting graphs from load data.
let me give brief explanation of my work,
There are two push buttons, 'Load data' and 'Plot data' from where I can load data and then it will plot the data in given location like shown in figure.
I have matlab code ready which imports data from excel file and then it plot the data. here my question is Can I callback this matlab code to push buttons and plot the data in GUI?
and if we cannot callback matlab code then how can import all data with 'Load data' push button?

Ashwini - yes, you should be able to use your other MATLAB code depending upon how it is written. You will want it to be a function so that you can pass in the data and/or filename (of the data to import) and pass in the axes handle where you want to plot the data.

For 1., how are you calling it? Evidently you're doing something like
[Engine_Speed, Engine_Power_ON, Engine_Power_OFF, Gear_One, Gear_Two] = LoadData();
If you do that you need to define output arguments:
function [Engine_Speed, Engine_Power_ON, Engine_Power_OFF, Gear_One, Gear_Two] = LoadData()

Your pushbutton callback can call other functions. Just make sure the function is in the mlapp or .m file, or on the search path, or in the same folder as your app. It should work then.
