Hi, just starting to use matlab here, running a few experimental calculations and pretty excited so far.
I'm currently struggling with displaying a graph of cumulative relative returns where changing value axis scale to log seems to defeat percentage formatting and override it with a default format, making presentation hard to grasp.
figure;
ax = axes;
plot(sourceData.Date, sourceData.ResultCompound);
ytickformat(ax, 'percentage'); % also tried ytickformat(ax, '%0.2f%%')
ax.YScale = 'log'; % no problem with default/'linear'
So my question is, is there a way to make log-scaled graphs with percentage tick labels?

I am not certain what you want to do.
Try this:
x = linspace(-2, 2, 50); % Create Data
y = exp(-(x).^2/2); % Create Data
figure
semilogy(x, y)
grid
yt = get(gca, 'YTick');
ytl = compose('%.0f%%', yt*100)
set(gca, 'YTick',yt, 'YTickLabel',ytl)
.

My pleasure!
I am not certain what you want. It is straightforward to define new ticks and tick labels.
This one change to my original code does that:
x = linspace(-2, 2, 50); % Create Data
y = exp(-(x).^2/2); % Create Data
figure
semilogy(x, y)
grid
yt = get(gca, 'YTick');
ytn = linspace(min(yt), max(yt), 4); % Define Nes ‘ytick’ Values
ytl = compose('%.1f%%', ytn*100)
set(gca, 'YTick',ytn, 'YTickLabel',ytl)
The new tick values always need to be within the range of the current tick values, however within that range they can be anything.

From what I can tell, the ruler object ignores the TickLabelFormat property (which is set by ytickformat) when the Scale is 'log'. I will record an enhancement/documentation request about this.
As a workaround, you can set the tick labels directly to whatever strings you want by using yticklabels. Try something like this:
yticklabels(string(yticks) + "%")

Thanks, Dmitriy. I have your comments to the enhancement request record.
