[FIXED] How to make tick label with subscript bold?

Issue

I have the following dictionary with labels, where I'd like to plot K1/2 as K with subscript 1/2.

labels = {'label': 'Label1', 'Label2', '$K_{1/2}$'}

I then want to plot the xticks in bold and size 22, however, K1/2 is not plotted in bolt as only label. How can I fix this?

plt.xticks(fontweight = 'bold', fontsize = 22)

Solution

This worked for me!

 plt.xlabel(r'$\bf{K_{1/2}}$')
