Is there a potential bug in the labeling function of the levelplot?

[cerium1925]

This issue arises because levelplot uses a fixed font size when setting the legend. When different level plots are combined into one figure and the figure is resized, the legend fonts for each subplot don't seem to adjust according to the adaptive size of the MATLAB figure window. The test results are shown in the following figure:

The likelihood of this issue occurring is low, and it can be mitigated by not setting a fixed font size, allowing MATLAB to handle it automatically. The test code is as follows:
clc, clear, clf;

Exp.mwFreq = 9.8; % 9.8404
Exp.Range = [0 900];
Exp.nPoints = 1e4;

Exp.SampleFrame = [0 0 0]; % z
