Add Label

[tomdertech]

Since show_label has been removed, please could someone provide an example of how to overlay a label to show the value? I cannot figure it out - Thank you.

This works for me:

Knob:
    min: 0
    max: 100
    size: 100, 100
    value: 0
    show_marker: False
    knobimg_source: "img/knob_metal.png"

    Label:
        text: "{}".format(int(self.parent.value))
        center: self.parent.center
        font_size: 20
        color: 0.1, 0.1, 0.1, 1

    self.bind(value=self.update_label_text)
    self.update_label_text()

    voltage = round(self.value * 5 / 360, 2)
    self.voltage = voltage
    self.label_text = f"{voltage}V"

LOAD KV UIX

KV = '''

The previous code convert the Label 0-360º to 0-5Vdc. Use as you wish.
