Currently I,m working on CPU consumption and memory consumption visualizing tool for large distributed system. There are so many processes running. Some times this will covers the processes of whole day and generates graphs. For the clearance of the graph I'm changing the width of the figure size according to the time rang. Height of the figure size is constant. Output is png and it's more like the structure of a ECG printout. But when the figure width passes the 288 (for dpi=500), python was giving segmentation fault and matplotlib was crashed. What is the maximum capacity of this library?
