I have a CSV file that specifies three real numbers x, y, v
, and I need to generate a plot (ListPlot
, joined) with the lines colored according to the value of v
.
But let's consider the simplest case, where v
can be +1
or -1
. Where values are +1
the line should be green, and blue where v
is -1
(or solid/dotted).
For instance:
0, 0, +1 `
1, 1, +1 | < GREEN
2, 4, +1 /
3, 2, -1 ` < BLUE
4, 1, -1 /
5, 4, +1 ` < GREEN
Is there a way of using the values and produce a plot? The questions I've found are about using a color function, but in this case I have no function as such.
