I have a 2D plot, attached as an image and would ask how to remove the triangle, x etc. markers on my curves. The code is also here:
yyaxis left
ax=gca;
ax.YColor='k';
plot(t,a_res_pool,'Color','[0.3 0 1]','LineWidth',2)
grid on;
grid minor;
title('pool, chest and belt 45°');
xlabel ('time [s]');
ylabel ('acceleration [g]');
hold on
plot(t,a_res_chest,'r','LineWidth',2);
plot(t,pool_a_x,'c','LineWidth',2);
plot(t,pool_a_y,'Color','[0 0.2 0.5]','LineWidth',2,'LineStyle','-');
plot(t,pool_a_z,'Color','[0.1 1 0]','LineWidth',2,'LineStyle','-');
plot(t,chest_a_x,'Color','[1 0.5 0]','LineWidth',2,'LineStyle','-');
plot(t,chest_a_y,'Color','[1 0 1]','LineWidth',2,'LineStyle','-');
plot(t,chest_a_z,'y','LineWidth',2,'LineStyle','-');

It's not clear to me why the markers are appearing in the first place based on this code. These plot commands should not produce any markers. When is substitute values in for your variables and produce these plots, no markers appear (nor should they, because you hvaen't defined a marker type).

HI, you can use the Marker Name-Value Pair of the function plot to specify the marker type. If you specify 'none', then no marker will be used. Refer the code below.
yyaxis left
ax=gca;
ax.YColor='k';
plot(t, a_res_pool, 'Color', '[0.3 0 1]', 'LineWidth', 2, 'LineStyle', '-', 'Marker', 'none')
grid on;
grid minor;
title('pool, chest and belt 45°');
xlabel ('time [s]');
ylabel ('acceleration [g]');
hold on;
plot(t, a_res_chest, 'r', 'LineWidth', 2, 'LineStyle', '-', 'Marker', 'none');
plot(t, pool_a_x, 'c', 'LineWidth', 2, 'LineStyle','-', 'Marker', 'none');
plot(t, pool_a_y, 'Color', '[0 0.2 0.5]', 'LineWidth',2, 'LineStyle','-', 'Marker', 'none');
plot(t, pool_a_z, 'Color', '[0.1 1 0]', 'LineWidth',2, 'LineStyle','-', 'Marker', 'none');
plot(t, chest_a_x, 'Color', '[1 0.5 0]', 'LineWidth',2, 'LineStyle','-', 'Marker', 'none');
plot(t, chest_a_y, 'Color', '[1 0 1]', 'LineWidth',2, 'LineStyle','-', 'Marker', 'none');
plot(t, chest_a_z, 'y', 'LineWidth', 2, 'LineStyle', '-', 'Marker', 'none');
Hope this helps!

thx for the response, the problem was fixed alreasy by declaring '-' at the after the colour.
Somehow 'Marker','none' didn't work...

Setting Marker to none as Subhadeep Koley demonstrated should have worked (it should have resulted in no markers). But the simpler solution is to just set the line properties and not set any marker properties as the code does in your question.
