After opening the example data, we can see that the plot has default axis labels and scales. By left-clicking on the axis labels (e.g., “X Axis” or “Y Axis”), we can edit them to more meaningful names. Similarly, by left-clicking on the scale labels (e.g., “1.0” on the X-axis), we can change the scale values. This allows us to customize the plot to better represent the data being visualized.

There is some limited support for mathematical expressions in the axis labels using LaTeX syntax. For example, we can label an axis as “$nm^{-1}$” to represent nanometers.

# After editing the axis labels and scales, the plot now reflects these changes with the updated labels and scales.
# This enhances the clarity and interpretability of the plot, making it easier to understand the data being presented.

Finally, we can see the main window with the updated axis labels and scales reflected in the plot.
