would it be easier to have all data in a single file and then tell
matplotlib to plot different parts of that file?
The file would look like:
.
.
.
13.0576 -66.6586 -9.6419 34.1672 1.445e+05 4962
13.0576 -55.4192 44.0864 16.7687 1.445e+05 4963
13.0576 65.0328 -38.8888 -215.3602 1.445e+05 4964
13.0576 -110.7375 -0.1741 -91.9251 5.459e+04 4512
.
.
.
The fifth column is what defines the transition between a file and the next one
How can I tell matplotlib to plot those data first with a certain
color and then the next data with a different color?
