Hello Koldo,

thanks a lot for that snippet of code, exactly what I was looking for.
Your sketch demonstrates to me something that I guess I've grasped before: the offset and spacing, given via AddSeries(), allows you to submit several time series that are not precisely aligned along axis X (= in time, typically).

And, I now finally understand what the "minor" units are.
The Major unit is clear, that is the dotted grid spacing.
The "minor" unit, as given by SetMinUnits(), is the offset of the dotted grid from the axis minima, as given by SetXYMin().
(Counter-intuitively to me, this is not a second smaller "axis tick mark" or anything like that.)

For the record, for people who may come later and may be just as lost as I was, I'll attach two screenshots of my app, with comments inscribed. They correspond to the following two snippets of UPP code:

Chart1.SetXYMin(min_freq, -90).SetRange(max_freq - min_freq, 90).SetMinUnits(0,0).SetMajorUnits(1000000, 10);

Chart1.SetXYMin(min_freq, -90).SetRange(max_freq - min_freq, 90).SetMinUnits(100000,5).SetMajorUnits(1000000, 10);

And, if I divide the x0 and DeltaX (= parameters to AddSeries() ) by a million, the DeltaX gets fractional, which is no problem, and I get a display in 3-digit MHz, rather than 9-digit Hz Smile

Smile

Good...

Frank
