Thank you for your previous help. Here my last question regarding this topic. Thank you in advance :) BR Mueller Philipp
Matlab sets automat. the x/y range of the diagram depending on the input data. I want to set it manually. Matlab should not set it.
axis ([ -500 500 0 222]); This command does not work.
If i use this command all other diagrams are also involved and changed.
I want for each diagram own limits for x and y (z).

Philip,
I am unable to reproduce your issue with | axis ([ -500 500 0 222])| changing the limits of all plots.
However, you can specify the axes on which axis or xlim operate as follows:
axis(subplot(3,2,5), [0 20 0 10])
xlim(subplot(3,2,5), [0 10])
Hopefully this will help you.

While the above works to address the given subplot, it masks the more fundamental issue that OP's code destroys the axes handles for previous subplot axes retaining only the last. This likely will be an issue in other properties and certainly makes enhancement/revision of the script much more difficult than using the handles themselves directly.
While the subplot(N,M,i) notation in this syntax does return the particular subplot handle by reexamining the currently existing locations, that's additional effort if just save the handles w/o overwriting the array initially.

...
for i = 1:length(plotPositions)
plotHandle = subplot(3, 2, i);
...
The above is the root of your problems...you're overwriting the axes handle of each subplot into the same variable, thus losing access to all of them excepting the last one. Create and use each separately to ensure do what you want on each axes object.
...
nPlots=length(plotPositions); % shorthand variable for convenience
hAx=zeros(nPlots,1); % preallocate array for axes/subplot handles
for i = 1:nPlots
hAx(i)=subplot(3, 2, i); % and save each so don't lose any of 'em...
...
% do whatever to create subplot here...
axis(hAx(i),[ -500 500 0 222]); % will set for current axes only
...
end
Of course, if each is to have its own set of limits, then you need the numeric values in the axis statement to reflect the proper ones for that axis; if they're known a priori then an array would be one way to hold the values; otherwise compute them from the data or get from user or whatever. The key is still to apply the desired set to the axis intended and only to that axis. Using the explicit handle will solve that issue (and probably many others for other properties as well). Otherwise, HG commands will operate on whichever axis happens to be current which can change at will with user interaction or, as in your code, to the last one created because that's what that handle variable you kept refers to if you use it.
See the last portion of the doc for axes where it says...
>> help axis
axis Control axis scaling and appearance.
axis([XMIN XMAX YMIN YMAX]) sets scaling for the x- and y-axes
on the current plot.
...
axis(H,...) changes the axes handles listed in vector H.
