The problem is quite forward, I can't see the line of the graph, and when I press any button. The time of the X axes should change accordignally to which button is pressed I have been looking through the documentation, for quite some time, but still can't figure it out.

)}
<button className='time__format' onClick={() => setTimeFormat("24h")}>24h</button>
<button className='time__format' onClick={() => setTimeFormat("7d")}>7d</button>
<button className='time__format' onClick={() => setTimeFormat("1y")}>1y</button>
</div>
);
};
export default ChartData;
from Line chart is not being displayed in Chart.js
