Hi, I am trying to figure out why my tooltips are not showing on a xychart in perspective.

Also I am wondering if its a problom of bool values. The bool values of props in the IDE are in lowercase (true/false) while in python it’s Uppercased (True, False). I am a bit confused in the way writing json/python object structure.

Here is pasted “serie json” props. This is called from within a function that returns the serie object then the single serie is appended to the series array.

```python
def getSerieWithColor(layerId, hexColor):
serie = {
		'name':'Layer ' + str(layerId),
		'label':'Layer ' + str(layerId),
		'defaultState':{'visible':True},
		'data':{
			'source':'data_layer' + str(layerId),
			'x':'GANTRY_POSITION',
			'y':'CARRIAGE_POSITION'
		},
		'xAxis':'x_axis_gantry_pos',
		'yAxis':'y_axis_carriage_pos',
		'zIndex':layerId,
		'render':'line',
		'line':{
			'appearance':{
				'stroke':{'width':0},
				'fill':{'color':hexColor, 'opacity':0},
				'bullets':[{
							'enabled':True,
							'render':'circle',
							'width':10,
							'height':10,
							'tooltip':{
								'enabled':True,
								'text':'hello'
							}
						}]	
			}
		}
return serie

```

I can't speak to the actual problem, but I can help with this; yes, the way you've written your script is correct. Python's `True/False` will be automatically encoded into JSON's `true/false` when the Python dictionary is parsed into a JSON structure.
