If that's how it looks, the diagram is corrupted.

Probably because the diagram coordinates are 16 bit, and the limits where exceeded.

I don't know if it can be fixed, but I do know there's no quick fix. It will require the VI for sure.

I'd try to use scripting to get all nodes and wires (recursively) and set all object coordinates to 0,0. Then try if diagram cleanup can fix it. Alternatively, try to fix node coordinates of objects that have invalid coordinates, but it will be fiddly for sure.

Pull an older and non-corrupted revision of your VI from your SCC tool (or some other backup).

Cleanup that older revision before attempting to add "new enhancements"…

Looks more like a graphic issue. 

Are your display driver up to date? 

If you scroll on the block diagram does it fix the view?

when scroll not fixed , i think my graphic driver is uodated

I agree with Wiebe that you most likely exceeded the valid range for the block diagram. You can read more about it here.

(It is even possible that the diagram cleanup action itself pushed it over the edge)
