Is it possible to use an expression to only show labels when they are over a certain x value or y value, i.e. using {valueX} inside an expression?

current json below (without expression)  
[  
{  
“enabled”: true,  
“render”: “label”,  
“width”: 1,  
“height”: 1,  
“label”: {  
“text”: “{valueX}”,  
“position”: {  
“dx”: 1,  
“dy”: -5  
}  
},  
“tooltip”: {  
“enabled”: true,  
“text”: “{name}: [bold]{valueY}[/]”,  
“cornerRadius”: 3,  
“pointerLength”: 4,  
“background”: {  
“color”: “”,  
“opacity”: 1  
}  
},  
“fill”: {  
“color”: “”,  
“opacity”: 1  
},  
“stroke”: {  
“color”: “”,  
“width”: 1,  
“opacity”: 1  
},  
“rotation”: 0,  
“deriveFieldsFromData”: {  
“fill”: {  
“color”: “”,  
“opacity”: “”  
},  
“stroke”: {  
“color”: “”,  
“opacity”: “”,  
“width”: “”  
},  
“rotation”: “”  
},  
“heatRules”: {  
“enabled”: false,  
“max”: 100,

}  
}  
]

Did you get this solved?  
I have the same issue. Not sure how we can use logic with y / x value.

Did you try an expression binding on the text property to return the value? Something like:

```auto
if(
    {someTagValue} > 10,
    “{valueX}”,
    ""
)
```

Hi @Transistor ,

I tried that, but I’m getting a null first argument.

Sorry, in the method I'm suggesting you would bind the text to another tag or property, not the `{valueY}` and that would turn on or off the text for all the points in that plot.

I wondering if it could read the values (valueY) and use the logic for each one.  
The expression works fine if I need to reference it to a tag or specific value.

Thanks anyway.

The XY Chart component is based on  
[https://www.amcharts.com/docs/v4/chart-types/xy-chart/](https://www.amcharts.com/docs/v4/chart-types/xy-chart/)

It won’t support logic on the built-in variables.

Sadly. But I understand.  
I’ll find a workaround.

Thanks again!
