Enter a value in TextInput and modify my graph automatically.

Hello, I need help from the community.
I have created a viewer app with Bokeh which contains different tabs. I have only one data source.
On the screenshot below I have different graphics and a TextInput widget. In this widget there is a value that I defined in my script. This value changes often and I have to change it by hand in the script. Is there a way for the user to enter the value on their own into the TextInput widget and this will update the tab’s graphics?
