I will provide a set of numerical values that need to be visualised as a single, clear line chart in MATLAB. Your task is to write clean, well-commented code that reads the data, plots the line, and applies professional touches—titles, axis labels (including units where relevant), grid, and a legend if the dataset contains multiple series. The script should run without extra toolboxes beyond core MATLAB, and it must save the figure to both PNG and PDF so I can drop it straight into a report. Please keep the code easy to modify; I may want to change colours, markers, or axis limits later. If you feel an alternative chart style would highlight key patterns better, mention it in your notes—flexibility is welcome, but the final deliverable must include the requested line chart. Deliverables: • An .m file that imports my data and produces the line chart • Exported PNG and PDF of the figure (high-resolution) • Brief inline or separate comments explaining any parameters I might tweak Accuracy of the plot, readable labels, and neat formatting will be the acceptance criteria.
