The nature of Sense is that things will shift about, whether it be because of user selections or because of different users having different resolution monitors. It is therefore generally best to let Sense sort out the scale.
Because of this, there is no mechanism to force the step on chart axis.
Another thing I have spotted is that on your charts although they are next to each other they are all on different scales. This could make them confusing. You might want to look at a trellis object to put each of the charts on the same scale - or set the max value yourself with something like:
Measures: Pmin,Pmax,Tmin,Tmax all the values are max 250 only. then i have taken scale max 250. but in that scenario some symbols are not properly shown like Pmin-29,Pmax-30, T-min-0,T-max- 34. that one point difference not clearly shown. then i have used rangemax((pmax),(tmax)).
for this can you provide any suggestion.
in this no aggr. only min and max i have used in measures. min(Pmin) like.
