How to use the chart and price table

• Interactive visualisation
  The chart displays the daily evolution of copper prices in US dollars (USD) and euros (EUR). You can enable or disable each currency by clicking its name in the legend at the top of the chart.
• Zoom and navigation
  To analyse a specific period:
  • Use the mouse wheel or the pinch gesture (on touch devices) to zoom in on the time axis.
  • Drag the chart horizontally to move through dates once zoom has been applied.
  • At any time, you can return to a broader view by adjusting the zoom again.
• Manual date selection
  Using the date selectors located above the chart, you can define a custom range. When dates are modified, the chart and table automatically update to display only the data within that period.
• Quick access buttons
  To make analysis easier, quick shortcuts are available to automatically adjust the data range:
  • Last month: displays prices from the last 30 days.
  • Last year: shows the evolution over the past full year.
  • All: resets the view to display the entire available historical dataset.
• Data table
  Below the chart, a table displays the exact daily values. The data is ordered by date, making it easy to consult specific prices and compare them with the visual information shown in the chart.
