Plot multiple lines from a matrix

I have a 14X897 matrix and I would like to plot 14 lines with individual label (each has the 897 values in Y axis) against the same X axis. Here is the code I have and it generate the "Error using matlab.graphics.chart.primitive.Stair/set Invalid parameter/value pair arguments." error. In this example, PD_G_GLOCA_dBW is the 14*897 matrix.

for gloca_plot=1:size(PD_G_GLOCA_dBW,1)
   g_(gloca_plot)=stairs(x5,PD_G_GLOCA_dBW(gloca_plot,:));
end;
hold off;
set(g_(gloca_plot),'DisplayName','GLONASS L1_%s',gloca_plot);

set(g_(gloca_plot),'DisplayName', sprintf('GLONASS L1_%s',gloca_plot));

thanks, I realize making a mistake on the %s, too. After fixing it with %d, it works well.
