labelling issue in graph plotting

plot(r,v1_lower,r,v1_upper,'LineWidth',4)

xlabel('r')

ylabel('\widetilde\nu_1(\chi ,\tau ;r )')

%subplot(2,2,2)

plot(r,v2_lower,r,v2_upper,'LineWidth',4)

xlabel('r')

ylabel('\widetilde\nu_2(\chi ,\tau ;r )')

%subplot(2,2,3)

plot(r,v3_lower,r,v3_upper,'LineWidth',4)

xlabel('r')

ylabel('\widetilde\nu_3(\chi ,\tau ;r )')

Due to \widetilde the y axis is not displayed \widetilde\nu_3(\chi ,\tau ;r ) the notation are not displayed

Hi @yogeshwari patel,

I understand the issue that you are encountering here in labeling the y-axis in the MATLAB plots.

The issue is that LaTeX commands like '\widetilde' weren't enclosed in dollar signs ($) and MATLAB wasn't set to interpret labels with LaTeX.

You can refer to the below mentioned code snippet and the attached output for better understanding:

plot(r, v1_lower, r, v1_upper, 'LineWidth', 2);
xlabel('r');
ylabel('$\widetilde{\nu}_1(\chi ,\tau ;r )$', 'Interpreter', 'latex');
title('Plot of $\widetilde{\nu}_1$', 'Interpreter', 'latex');
legend('Lower', 'Upper');

Output:

To learn more about using LaTex to format titles and axis labels, you can refer to the following documentation:

Hope this helps!
