Values on axis is big (or small) enough and are displayed like 1.0×10⁷, 1.2×10⁷, 1.4×10⁷, etc. I want to extract the multiplier ×10⁷ from each label and put it separately.

Follow this steps:

1. Open Figure/Plot Properties, than go to Axes Properties tab, than go to Axis Style tab and select the appropriate axis tab.
2. In Major Labels section set Multiplier value to 10^-7 (1e-7).
3. Add text ×10⁷ to axis title or create new text label with this text. Example: Voltage, V, ×10⁷
