Print a value on a plot

I am measuring and ploting the 10 to 90% risetime of a pulse. I need to put the value of the risetime on the plot. Below is my code. The value I need to print on the plot is RTC

for k1 = 1:2

RTC=risetime(xcr,tcr);% "risetime(x,t)" is the 10 to 90% risetime of the closed circuit pulse.

end

figure('DefaultAxesFontSize',4);%create a figure 10 for the closed circuit rise time plot

grid on;

risetime(xcr,tcr);

xlim([-0.01e-7, 0.015e-6]);

ylabel('Voltage (kV)')

xlim([2.9*1e-7 3.5*1e-7]);% center the rise time wave

legend('Closed (loaded) circuit 10 to 90% Rise Time');

I'd recommend taking a look at this

Make sure to use num2str to convert the number into text.

I changed my code to the following. Now it prints the test "Rise Time(s)" in the correct place on the plot. I need it to print the actual value of "s" where is prints "(s).

for k1 = 1:2

RTC=risetime(xcr,tcr);% "risetime(x,t)" is the 10 to 90% risetime of the closed circuit pulse.

end

%Plot 8

figure('DefaultAxesFontSize',4);%create a figure 10 for the closed circuit rise time plot

grid on;

risetime(xcr,tcr);%Put this data in the plot

s = num2str(RTC);

text(3.1e-7,32,'Rise Time(s)');

xlim([-0.01e-7, 0.015e-6]);% set the x min/max and y min/max in this order.--xlim([-1.45e-7, -1.39e-7]) Note: the Y azis will not plot below 0

ylabel('Voltage (kV)')

xlim([2.9*1e-7 3.5*1e-7]);% center the rise time wave

legend('Closed (loaded) circuit 10 to 90% Rise Time');

Change it like this

text(3.1e-7,32,s);
