Remove empty space from Streamlit Echarts - echarts

Question

I am rendering a gauge component in the following way, within my Streamlit app:
option = {
"series": [
{
"type": "gauge",
"startAngle": 180,
"endAngle": 0,
"min": min_range_val,
"max": max_range_val,
"center": ["40%", "40%"],
"splitNumber": 5,
"axisLine": {
"lineStyle": {
"width": 6,
"color": [
[0.25, "#FF403F"],
[0.5, "#ffa500"],
[0.75, "#FDDD60"],
[1, "#64C88A"],
],
}
},
"pointer": {
"icon": "path://M12.8,0.7l12,40.1H0.7L12.8,0.7z",
"length": "12%",
"width": 30,
"offsetCenter": [0, "-60%"],
"itemStyle": {"color": "auto"},
},
"axisTick": {"length": 10, "lineStyle": {"color": "auto", "width": 2}},
"splitLine": {"length": 15, "lineStyle": {"color": "auto", "width": 5}},
"axisLabel": {
"color": "#464646",
"fontSize": 12,
"distance": -60,
},
"title": {"offsetCenter": [0, "-20%"], "fontSize": 20},
"detail": {
"fontSize": 30,
"offsetCenter": [0, "0%"],
"valueAnimation": True,
"color": "auto",
"formatter": "{value}%",
},
"data": [{"value": value, "name": caption}],
}
]
}
st_echarts(option, width="450px", height="350px", key="gauge")
However, it seems like an additional empty extra white space is added at the bottom of the component (as from the following image).
How can I effectively remove that and keep only a tiny margin all around the gauge?

Answer 1

The following parameters must be added:
radius: '120%',
center: ['50%', '80%']
The latter one should be adjusted according to specific use cases.
