Chart does not retain it's position

[Indhumathi2016]

In my case one can add a node between two nodes and the links will be automatically generated between these.For that i've updating the chart's intialValue every time when nodes are updated. Everything working fine. But the issue is whenever have added a node the "transform" is resetting with "react-pan-pinch" so that it's look like chart is moved to top position, i don't need this i just want the transformation as it is.
