Marker Indices automation using 'set' function

I have a script with a lot of plotting, and this involves markers which, howewer, have same parameters all over. Now, is there any way to streamline the code, so it doesn't have to repeat these lines all over and over again?

h = plot(49,8.4745,'o-','MarkerFaceColor','blue','MarkerEdgeColor','blue','MarkerIndices',1);

h = plot(50,21.4411,'o-','MarkerFaceColor','blue','MarkerEdgeColor','blue','MarkerIndices',1);

h = plot(50,39.5221,'o-','MarkerFaceColor','blue','MarkerEdgeColor','blue','MarkerIndices',1);

h = plot(50,76.2767,'o-','MarkerFaceColor','blue','MarkerEdgeColor','blue','MarkerIndices',1);

I tried to rewrite it into this

h1 = plot(x1,y1);

h2 = plot(x2,y2);

h3 = plot(x2,y3);

h4 = plot(x2,y4);

set([h1 h2 h3 h4],'o-','MarkerFaceColor','blue','MarkerEdgeColor','blue','MarkerIndices',1)

But I keep getting an error

Error using matlab.graphics.chart.primitive.Line/set

What you've written second would almost work if you turned hold on. However you can't use a line specification in a set call like you did. If you replaced 'o-' with 'Marker', 'o', 'LineStyle', '-' it should work.

x = 0:360;
h1 = plot(x, sind(x));
hold on
h2 = plot(x, sind(2*x));
set([h1 h2], 'Marker', 'o', 'MarkerIndices', 1:45:361)

Or you could write a function handle and use that function handle with your data as input.

plotMe = @(x, y) plot(x, y, 'Marker', 'o', 'MarkerIndices', 1:45:361);
figure
x = 0:360;
plotMe(x, sind(x));
hold on
plotMe(x, sind(2*x));

OK so I shortened the code and now I have:

h1 = plot(x1,y1);

h2 = plot(x2,y2);

h3 = plot(x2,y3);

h4 = plot(x2,y4);

set([h1 h2 h3 h4], 'Marker', 'o', 'LineStyle', '-','MarkerFaceColor','blue','MarkerEdgeColor','blue','MarkerIndices',1)

howewer I still have to repeat it in every plot chart. I keep wondering, how to implement all this in one function, and then only insert this function into my plot charts.

I tried with this

x1 = 49;

x2 = 50;

y1 = 8.4745;

y2 = 21.4411;

y3 = 39.5221;

y4 = 76.2767;

h1 = plot(x1,y1);

h2 = plot(x2,y2);

h3 = plot(x2,y3);

h4 = plot(x2,y4);

PlotMe = [h1, h2, h3, h4];

set(PlotMe, 'Marker', 'o', 'LineStyle', '-','MarkerFaceColor','blue','MarkerEdgeColor','blue','MarkerIndices',1)

But somehow I got an error regardless.

Coordinates for markers are the same for all charts, just like their color and shape

Forgot to accept your answer, sorry I rectified this.
