User Interactions

LightningChart Python allows developers to control user interactions with charts and components using the set_user_interactions() method. This can disable, restore, or customize interactions like pan, zoom, drag, and more. It provides consistent customization for all major chart types and UI elements.

chart.set_user_interactions(config)
  • None: disables all user interactions
  • {} or no argument: restores default interaction behavior
  • dict: custom configuration per interaction type

ChartXY​

chart.set_user_interactions(None)  # Disable all
chart.set_user_interactions()      # Restore defaults

# Custom configuration
chart.set_user_interactions({
    'pan': {
        'lmb': {'drag': True},
        'rmb': False,
    },
    'rectangleZoom': {
        'lmb': False,
        'rmb': {'drag': True},
    },
})

Chart3D​

chart.set_user_interactions({
    'zoom': {
        'wheel': {
            'camera': False
        }
    }
})

Parallel Coordinates​

# Disable specific range selector interactions
chart.set_user_interactions({
    'rangeSelectors': {
        'create': {'doubleClickAxis': False},
        'dispose': {'doubleClick': False},
    }
})

TreeMap​

chart.set_user_interactions(None)      # Disable all
chart.set_user_interactions({})        # Restore

chart.set_user_interactions(           # Enable/Disable drill down into specific nodes
    {
        'drillDown': {
            'click': False,
        },
    }
)

Zoom Band Chart​

zbc.set_user_interactions({
    'pan': {'drag': False, 'click': True},
    'zoom': {'wheel': 'undefined', 'dragKnob': False},
})

Constant Line​

line.set_user_interactions({
    'move': {'drag': False, 'ctrl': {'drag': True}}
})

Band Element​

band.set_user_interactions({'scale': False})  # Only disable scaling

Axis​

axis.set_user_interactions({
    'pan': {
        'lmb': {'drag': True},
        'rmb': False,
        'mmb': False,
    },
    'rectangleZoom': {
        'lmb': False,
        'rmb': {'drag': True},
        'mmb': False,
    },
})
