Create a legend according to the colors of a scatter plot
7 views (last 30 days)
Hi, I have the gps coordinates (xCG and yCG) of the trajectories in a circuit of different drivers, what I would like to do is represent these colored trajectories based on the gear engaged which is saved in an NGear vector. This I did with a scatter plot like below:
Now I want to create a legend like this:
legend('Gear 1','Gear 2','Gear 3','Gear 4','Gear 5','Neutral');
But clearly I would like the color in the legend to match the color in the plot. The problem is that NGear does not always contain all five gears, because for example the 5th gear is not put in one lap, this then changes from driver to driver.
So, my question is, there is a way to fix 6 colors accorting to that labels in the legend and than reproduce the same colors in the plot according to the gear engaged?
