Yes—enable 'Fill Area' to convert lines into area charts. You can also create stacked area charts to show cumulative totals over time.

Add multiple value columns to your data. Each column becomes a separate line with its own color. The legend shows all series names from your header row.

Yes—enable 'Show Points' to display markers at each data point. You can also show value labels above each point for precise readings.

Line charts connect points with diagonal lines showing continuous change. Step charts use horizontal and vertical lines, ideal for data that changes at specific moments rather than gradually.

Leave cells empty or use null for missing values. The chart will show a gap in the line. Enable 'Connect Nulls' to draw lines through missing data instead.

The basic chart shows your actual data. For trend analysis, calculate moving averages in your source data and add them as an additional series.

Choose from preset color palettes. Each series gets a distinct color. Enable 'Smooth Lines' for curved interpolation or keep straight line segments.
