Multiple statistics (Weibull) curves on one graph

Hi, I am trying to plot several Weibull functions on one graph. Using the attached code I was able to achieved the result shown in the attached Figure and edit each line individually. Meanwhile, I like the appearance of wblplot function, it is easy to use it for one set of data (one curve), however I can not plot several curves. I would greatly appreciate any sugestions on how I cna use wblplot, thanks.

Code:

figure

set(gca,'XMinorTick','on','YMinorTick','on', 'LineWidth', 0.5,'TickLength',[0.0125, 0.01]);

box

hold on

f1=probplot('weibull',[E182_7]);

f1(2).LineWidth = 1;

f1(2).Color = [0.929 0.694 0.125];

hold on

f2=probplot('weibull',[E182_18]);

f2(2).LineWidth = 1;

f2(2).Color = [0.8500 0.3250 0.0980];

grid on

xlabel('Breakdown strength (E_B), V/µm', 'interpreter', 'tex');

ylabel('Breakdown probability, %', 'interpreter', 'tex');

h=legend('7%','','18%','','Location','southeast');

title(h,'CCTO vol.% in Sylgard 182:')

Hello,

As per my understanding, you wish to plot multiple Weibull functions on a graph using “wblplot” function.

One possible workaround is to pass the Weibull functions to be plotted as parameters to the "wbplot" function, as shown below:

figure  
f = wblplot([E182_7 , E182_18]);

xlabel('Breakdown strength (E_B), V/µm', 'interpreter', 'tex'); 
ylabel('Breakdown probability, %', 'interpreter', 'tex'); 
h=legend('7%','','18%','','Location','southeast'); 
title(h,'CCTO vol.% in Sylgard 182:') 

Refer “wblplot” function documentation to know more about Weibull probability plots.

Hope this helps!

Hi Soujanya,

Thank you for your help.

I tried your code but receiving the following error (E182_7 and E182_18 are 1x20 arrays):

Error using wblplot (line 22)

Too many input arguments.

Error in Tests (line 137)

f=wblplot('weibull',[E182_7],[E182_18]);

File: Tests.m Line: 137 Column: 30

Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

I tried to remove extra parentheses, but first two errors are still there.

I would appreciate any sujestion on this.

Hi Stanislav,

Please try the below line of code:

f = wblplot([E182_7' , E182_18']);

Thanks,

Soujanya

Hi Soujanya,

It works now and I can edit each line individually as I did before. Thank you!

Bes wishes,
