Hi everybody, Thank you very much for your suggestion, Jim. I did not think of that graphical parameter "xaxs". It would really be a workaround for my first example. Unfortunately, it does not solve the second situation, where I would like to add the step function to an existing plot within a specified region. Internally, 'xlim' will always be expanded by 'dr' (=diff(xlim)) units to the left and to the right. Perhaps one could add an argument to the plot.stepfun function, with which one can specify this 'dr' variable (see the internals of plot.stepfun) ?
