Here is a script which exhibits the problem on the original computer running R2018a under Win7.
% TEST_MarkerFaceColor_V2
clear all;
close all;
x = linspace(0,3,4)
y = x
figure (1)
plot(x(1),y(1),'Marker','o','MarkerSize',20,'MarkerFaceColor','r','MarkerEdgeColor','k'); hold on;
plot(x(2),y(2),'Marker','o','MarkerSize',20,'MarkerFaceColor','g','MarkerEdgeColor','k'); hold on;
plot(x(3),y(3),'Marker','o','MarkerSize',20,'MarkerFaceColor','b','MarkerEdgeColor','k'); hold on;
plot(x(4),y(4),'Marker','o','MarkerSize',20,'MarkerFaceColor','k','MarkerEdgeColor','k'); hold on;
pause (3)
The markers are incorrectly colored on this computer. Markers show pie-shaped zones of different intensity, as in the fig files included with the original query.
However, the marker color is correct when this script is run on 2 other computers (R2017b, Win10), and (R2018a Win7). Changing the renderer did not solve the problem on the "guilty" computer. Any suggestions for possible origins of the problem? Is something set incorrectly in Matlab? Thank you. GH
