See https://www.mathworks.com/matlabcentral/fileexchange/?term=tag:%22digitize%22 for a number of contributions designed to extract plot data from images

Any tool box or code which automatically plot data?

Thank you

No. There is code in the File Exchange to extract data, but it does not then turn around and plot data.
