Spreadsheet task (Chart Creation):
Create a dashboard on a sheet named “Summary” to consolidate data from 2-hour racing events, organizing the data into 5-minute time blocks from 0 & 5 MINS through 115 & 120 MINS

Add a drop-down menu on the Summary sheet to allow users to select a racing event. Set the default selection to SEB'18.

Based on the selected racing event, dynamically display a multi-series line chart that visualizes the YELLOW, PIT, DRIVER CHANGE, Dive-in, and Worst Position data series across these time blocks.

Plot WORST POSITION as a standard line. Plot YELLOW, PIT, DRIVER CHANGE, and DIVE-IN as marker-only series (no connecting lines) using large markers, with each event placed at a separate negative y-value so they appear as distinct indicator rows below the zero line. Suppress markers where no event occurred. Hide the negative y-axis values.

Position the legend at the bottom of the chart.

The chart should be titled:
“Race Events by 5-Minute Time Intervals.”
