Hello,

I am plotting three columns of data using plot2d and I'm adding a legend box
using legends. I have declared the line colours for each plot to make the
graph easier to view. The problem that I have is that the legends box shows
all three of the lines in the same colour (blue). Is this an issue with the
way my code is written?
TIA James
<code>
// plot data
// the third column: -->m(:,3)
x1 = M1(:,1); // frequency
y1 = M1(:,2); // M1 Average
y2 = M2(:,2); // M2 Average
x2 = M3(:,1); // Limits frequency
y3 = M3(:,2); // Limits - average
plot2d(x1, y1, style= color('orange'), logflag = "ln");
plot2d(x1, y2, style= color('blue'), logflag = "ln");
plot2d(x2, y3, style= color('red'), logflag = "ln");
f = gca(); // get the current axes
bg_color = color('lightgray');
f.background= bg_color; //RGB
xtitle("EN55022 Conducted Emissions", "Frequency (MHz)", "dBuV");
legends(['uA7805';'7805SR'; 'EN55022B'],[2,2,2],opt="ur");
here [2 2 2] overwrites the colors you specified in the plot2d calls. I
would suggest:
legend('uA7805','7805SR','EN55022B','in_upper_right')

xgrid;
