Have Value Selected but Label Showing in Views Display Plugin

I am working on a custom Display plugin for Views. In my buildOptionsForm() method, I have the following:

$  form['inherit_yaxis'] = [   '#title' => $  this->t('The title'),   '#type' => 'radios',   '#options' => [      1 => $  this->t('Inherit primary of parent display'),      0 => $  this->t('Create a secondary axis'),   ],   '#default_value' => $  this->getOption('inherit_yaxis'),   '#description' => $  this->t('The description'), ]; 

In the optionsSummary(), if I do this:

$  options['inherit_yaxis']['value'] = $  this->getOption('inherit_yaxis'); 

It shows 1 or 0 rather than the label that I want (‘Inherit primary of parent display’ or ‘Create a secondary axis’).

What should be on the other side of $ options['inherit_yaxis']['value'] = so that the label shows but the value stays either 0 or 1?
