in this examplefirst get the axes using qmubyft once have these axes objectsi can adjust them by calling tfu@ymjni can set the range from - to and with set tfu@zmjni set the range from to you can see in the below outputthat my values are ranging from to and goes from to can also have explicit control over where the tick marks on the axes are so in the previous codei' saying want the ticks to be at etc and ticks from to at increments using the tfu@yujdlt and tfu@zujdlt functions now could use the bsbohf function to do that more compactlybut the point is you have explicit control over where exactly those tick marks happenand you can also skip some you can have them at whatever increments you want or whatever distribution you want beyond thatit' the same thing once 've adjusted my axesi just called qmpu with the functions that want to plot and called tipx to display it sure enoughthere you have the result adding grid what if want grid lines in my graphswellsame idea all do is call hsje that get back from qmubyft byft qmubyft byfttfu@ymjn byfttfu@zmjn byfttfu@yujdlt on the axes
