Feature request regarding histograms: The smooth frequency feature counts records with equal first field generating h(x). Another natural use case, however, is a combined plot of y(t) and h(y) sharing a vertical axis for y. I tried "using (bin(t)):(1.0) smooth frequency axes y1x2", which leads to "axes must be x1y1, x1y2, x2y1 or x2y2". If there is a good reason for that limitation, Plan B would be a switch to let smooth frequency count records with equal second field (after the : of using).
I do not understand exactly what you are asking for, but perhaps this example is related:

Ticket moved from /p/gnuplot/bugs/1907/
Can't be converted:
This is the required relation between y(t) and h(y), but the t axis is vertical instead of horizontal. We should not need a workaround to swap axes.
Sorry for the dead attachment links.
