Legend colors do not match plot colors.
显示 更早的评论
I have an Excel file (attached) that contains the latitude and longitude, starting and ending, for 198 tornadoes that occured between 2008 and 2018. I have a program (below) that plots each set of coordinates and colors it according to year. However, the legend colors do not match the plot colors. I have checked several of the questions posted here, but none seem to deal with for loops and if statements. Any help would be greatly appreciated! An if anyone can provide guidance on adding a scale ruler to this project, I would be greatful.
c01 = [0.2422 0.1504 0.6603];
c02 = [0.2803 0.2782 0.9221];
c03 = [0.2440 0.4358 0.9988];
c04 = [0.1540 0.5902 0.9218];
c05 = [0.0297 0.7082 0.8163];
c06 = [0.1938 0.7758 0.6251];
c07 = [0.5044 0.7993 0.3480];
c08 = [0.8634 0.7406 0.1596];
c09 = [0.9892 0.8136 0.1885];
c10 = [0.9769 0.9839 0.0805];
c11 = [0.2791 0.2625 0.9064];

You can also shorten your code:
c01 = [0.2422 0.1504 0.6603];
c02 = [0.2803 0.2782 0.9221];
c03 = [0.2440 0.4358 0.9988];
c04 = [0.1540 0.5902 0.9218];
c05 = [0.0297 0.7082 0.8163];
c06 = [0.1938 0.7758 0.6251];
c07 = [0.5044 0.7993 0.3480];
c08 = [0.8634 0.7406 0.1596];
c09 = [0.9892 0.8136 0.1885];
c10 = [0.9769 0.9839 0.0805];
c11 = [0.2791 0.2625 0.9064];
color = [c01;c02;c03;c04;c05;c06;c07;c08;c09;c10;c11];
data = xlsread('Tornado Data - 4th Clean No Duplicate Entries.xlsm');
dates = data(:,2);
[sorted_dates order]=sort(dates)
data=data(order,:) % rearrages your rows to be in order;
for i = 1:size(data,1) % for each row
geoplot([data(i,8 data(i,10],[data(i,9) data(i,11)]),...
'LineWidth',0.5,'Color',color(i),'Marker','*');
hold on;
end
lgd = legend({'2008','2009','2010','2011','2012','2013','2014','2015','2016','2017','2018'},'Location','eastoutside');
title(lgd,'Year')
