I have been given the task to take graphs and vector them to make them be able to scale up and down. Every time I live trace it, it comes out blotchy and I cant get it to remain someone crisp. I cam easily make the number increments out side of the graph easily but the information inside is very complicated to just try and recreate using the pen tool or anything
To be honest, I think you have been sent on a fools errand. Auto tracing that image will never look good.
As for scaling it, there is no problem. The image is a bitmap with solid pixels. This could easily be rescaled in Photoshop using Nearest Neighbour (preserve hard edges) as the interpolation method.
For example, here's an enlargement of just one small section. Click on it to see it full size.
