I have created a graph in MATLAB using gplot. The graph has >2000 nodes, hence there is a lot of overlap between nodes and the picture is not very clear. This is not such a big problem in MATLAB as I can zoom into the figure. But I want to save the file as a PDF. When I do this, the image is saved as a “screenshot”, which does not support zoom as it does in MATLAB. Is there any way in which I can save this graph as a PDF, or even any other format like BMP in which I can scroll or zoom the figure?
