For displaying figures in the Live Editor, a certain framework library is used. Due to differences in the specifications of this library’s versions across MATLAB releases, the fonts applied to text elements may vary, which is likely the cause of the display differences you are seeing.
By default, the axis font (FontName) is set to "Helvetica." This setting allows MATLAB to choose what it considers the most appropriate font for each computer environment. However, by specifying a commonly used font name like "Arial," you can explicitly control how the text is rendered. I recommend trying the following steps to set the fonts as desired:
ax = gca;ax.FontName = 'Arial'; % This will change the axis font, including the tick labels, at onceax.Title.FontName = "BIZ UDゴシック";ax.XLabel.FontName = "HG創英角ﾎﾟｯﾌﾟ体";ax.YLabel.FontName = "ＭＳ Ｐゴシック";
