Hi!
Using Matlab 2023b.
Plotting some data using plotyy, here is the example code:
data1 = [1 2 3 2.5 5 6 7];
data2 = [10 20 30 25 50 60 70];
Timestamp_datetime1 = datetime(2014,1:7,1)
Timestamp_datetime2 = datetime(2014,2:8,1)
figure
[hAx,hLine1,hLine2] = plotyy(Timestamp_datetime1, data1,Timestamp_datetime2, data2,'scatter','plot')
hLine2.LineStyle = '--'
Run the code and you will get this:
If I use the zoom in function and select the data around Apr 2014, I get this:
The data points are now out of alignment on the graph.
Has anybody come across this?

plotyy is not recommended. Instead, use yyaxis which replaces plotyy. I've converted your code below. yyaxis does not have the problem you've found in plotyy.
data1 = [1 2 3 2.5 5 6 7];
data2 = [10 20 30 25 50 60 70];
Timestamp_datetime1 = datetime(2014,1:7,1);
Timestamp_datetime2 = datetime(2014,2:8,1);
figure
yyaxis left
hLine1 = plot(Timestamp_datetime1, data1,'o');
yyaxis right
hLine2 = plot(Timestamp_datetime2, data2,'--');
