Design a user interface (Graphical User Interface - GUI or App Designer) using MATLAB to convert physical units: temperature or pressure. There are some requirements which are listed in below:

- Allows the user to put the value, which be converted and display the result with the corresponding units.

- Draw a histogram showing the historical variation using the converted values on the axes. Fully note the necessary content for the non-display area (the title of graph, conversion units)

Examples for temperature values (oC) are: 18; 20; 15; 30; 60; 13; 5; 7; 90; 70.

Examples for pressure values (Pa) are: 10; 20; 30; 50; 40; 23; 42; 71; 90; 62.

- The program can choose different options (types of units to be converted, reduced values to be converted, etc.). It is possible to assist in making selections of different units by using features such as: radio buttons/combo boxes/list boxes

- Can read data and batch convert data from externally available data tables, allowing conversion history to be saved.
