Format tick labels in histogram subplots

I want to plot 2 subplots both being histograms. For the first set, I want there to be 0.2 increments starting at 22, then, 22.2, 22.4, etc. until 34.

Same for the second set, except different limits based on the data I had on file.

Problem: When I graph this, the tick marks for suplot 1 is: [22.00 24.00, ... 34.00] But when squinting I can see the graph really is spaced out 0.2.

Same for second subplot except spaced out 0.25. How do I correct my code below?

I found I should use gca, but it doesn't seem to be working. Where should I add:

ax = gca;

ax.XAxis

xtickformat('%, 0.2f')

load data1.txt; %load text file while has 200 rows of data with 2 columns

x = data1(:,2); % take all rows in col 1

y = data1(:,1); %take all rows in col 2

figure

subplot (2,1,1)

histogram (x)

histogram(x, [22: 0.2: 34]) %the 22 to 34 is just the x limits I set for the data

subplot (2,1,2)

histogram (y)

histogram(y, [-1.5: 0.25: 1.5]) %change limits for your set of data.

Thanks guys!

Set the XTick Property of the Axes after plotting the histogram as the plot itself adjusts the XTicks based on the values of data being plotted .

subplot (2,1,1)
ax = gca;
ax.XLim = [22 34];
histogram (ax,x);
ax.XTick = 22:0.2:34;
 
subplot (2,1,2)
ax2 = gca;
ax2.XLim =[-1.5 1.5];
histogram (ax2,y)
ax2.XTick = -1.5:0.25:1.5;.
