Extending specific y-axis values

Hello,
I am currently plotting some ocean depth profiles and have been asked to extend the top couple of hundred meters. I was hoping that this just meant changing to a log scale, but it seems that I need to create a new 'y axis scale'. So is there a way to do this? Use say half the plot for the top 500 meters then the rest of the plot carries on to 5000 all linearly. Almost like the top half is zoomed in in regards to y and the bottom half in zoomed out. I know how odd this potentially sounds and I am not sure if this is possible.
Thank you,
Holly

It is not a supported feature, but you can make two axes and join them such that they appear to be one axes. For example
x = linspace(0, 7);
y = exp(x);
ax1 = axes('Position', [0.1 0.1 0.8 0.4]);
ax1.XLim = [0 7];
ax1.YLim = [0 20];
hold on;
plot(x, y);
ax2 = axes('Position', [0.1 0.5 0.8 0.4]);
ax2.XAxis.Visible = 'off';
ax2.YScale = 'log';
ax2.XLim = [0 7];
ax2.YLim = [20 1000];
hold on;
plot(x, y);

Yes, I don't see any reason that there will be an issue. Maybe you can try something similar and comment if there is some issue.
