Dynamically draw and move an axis and these labels

Not 100% sure what you're trying to do, but couldn't you simply use different images? That'd put the price on flash memory.

If you're trying to do something that changes dynamically The easy way is to use Box. e.g.

box.setPosition(0,0,1,20); // x=0, y=0, width=1, height=20

The more elegant approach is to override the ::draw() method in a custom widget (AxisWidget?) and simply write directly into the framebuffer - This would save some memory from not allocating Boxes. Not hard for something this simple.

But, it depends on what you're trying to do. Not quite sure what "move the axis according to a value" means - statically? dynamically? etc.

the objective is to graphically represent the position of a motorized carriage moving on a linear guide. so the position is dynamic. A fixed mark indicates the position relative to the moving axis (lines and label).
