Currently the nav button is just rendered next to the legends.
Current Behavior:

Expected Behavior:

OR

Current Code:
```
lineChartProps={{
className: "bn-build-history--chart",
scale: {
color: {
range: ["#d4335c", "#10b981", "#f59e0b", "#8b5cf6", "#06b6d4"],
},
},
xField: "index",
yField: "durationIncreasePercentage",
colorField: "config",
data: filteredData,
shapeField: "smooth",
point: {
shapeField: "circle",
sizeField: 6,
},
axis: {
x: {
label: false,
},
y: {
title: "Runtime",
label: false,
},
},
legend: {
color: {
position: "bottom",
maxRows: 2,
navLoop:true,
navOrientation:"vertical",
// navControllerSpacing:[50,50,50,50],
//navControllerPadding:[50,100,50,100],
itemLabelText: (value: {
id: string;
color: string;
label: string;
}) => {
return getBuildConfigName(
typeof value == "string" ? value : value.id,
configMap,
recentBuildsConfigMap
);
},
itemMarker: "circle",
},
},
style: {
lineWidth: 3,
},

tooltip: {
// title: (value: IChartData) =>
// dayjs(value.date).format("DD MMM YYYY hh:mm A"),
items: [
(datum: IChartData) => {
return {
name: getBuildConfigName(
datum.config,
configMap,
recentBuildsConfigMap
),
counter: datum.counter,
datum,
};
},
],
},
interaction: {
tooltip: {
enterable: true,
position:"bottom",
bounding: { x: 0, y: 50, width: 400, height: 10000 },

render: (
event: any,
options: {
title: string;
items: {
color: string;
name: string;
datum:IChartData;
counter: string;
}[];
}
) => {
return getTooltipItem(options.title, options.items, event);
},

Start by reading the legend color configuration and the navLoop, navOrientation, navControllerSpacing, and navControllerPadding options shown in the issue. Confirm how legend navigation is currently positioned and define the supported left- and right-anchored behavior with maintainers; done should include a documented configuration and verification against the expected layouts.
