Remove exponent from plot axis label
显示 更早的评论
Hi, all.
I'm trying to remove the scientific format from my Y-axis label for my plot in MATLAB R2020a shown below.
I've tried everything I can find but, for the life of me, I cannot seem to get the Y-axis labels to display 10, 100, etc. instead of 10^1, 10^2, etc.
My plot code is as follows:
figure; semilogy(Pos, TC1, Pos, TC2, Pos, TC4, Pos, TC16)
legend('1C', '2C', '4C', '16C')
xlabel('Air Sample Position')
ylabel('Temperature (^{o}C)')
title('Temperature vs Position')
grid on
ax = gca;
ax.YAxis.TickLabelFormat = '%.0f';
ax.YAxis.Scale = 'log';
ax.YAxis.ExponentMode = 'manual';
ax.YAxis.Exponent = 0;
ax.YAxis.MinorTick = 'on';
Can anyone assist, please?

But the doc doesn't say anything about ignoring TickLabelFormat for a log scale, I don't believe, which is the property that I think the Question is really about. For a semilogy plot, the Y-TickLabelFormat is %g, even though that's not the format actually used for display
semilogy(1:100,1:100),grid,ax = gca;
ax.XAxis.TickLabelFormat
ax.YAxis.TickLabelFormat % YTickLabels display should be similar/same to XTickLabels?
I poked around trying to find something that overrides the %g format for the YAxis, but couldn't find it. Maybe just a gap in the doc?

yticklabels(string(yticks))

Another alternative:
ax = gca();
ax.YTickLabel = ax.YTick;
In this case, MATLAB does the string conversion.

Thank you. I tried both of these approaches but it seems to just label every tick with '100', even when I change the tick values to [1 10 100].
Using a log scale, is it simply not possible? I was able to achieve the desired plot in Excel but I prefer the aesthetic of MATLAB plots.
I don't understand why you run into such an issue. Please see the code below.
Pos = 1:7;
TC1 = [20, 200, 350, 500, 350, 200, 20];
figure; semilogy(Pos, TC1)
legend('1C')
xlabel('Air Sample Position')
ylabel('Temperature (^{o}C)')
title('Temperature vs Position')
grid on
yticklabels(yticks)
