Spec Version: 1.0.0
A simple filled area chart showing a single data series over time or sequential x-values. The area between the data line and the baseline (typically zero) is filled with a semi-transparent color to emphasize the magnitude of values.
- x: Sequential or time-series values for the x-axis (numeric or datetime)
- y: Numeric values to plot on the y-axis
fill_alpha: Transparency of the filled area (type: float, default: 0.5)line_color: Color of the line and fill (type: str, default: library default)title: Chart title (type: str, default: None)x_label: Label for x-axis (type: str, default: column name)y_label: Label for y-axis (type: str, default: column name)
- X and Y axes are labeled with meaningful names
- Grid is visible but subtle (alpha <= 0.5)
- Area fill is semi-transparent (alpha between 0.3 and 0.7)
- Line on top of fill area is visible
- No overlapping axis labels or tick marks
- Data accurately represented without distortion
- Figure has appropriate size (16:9 aspect ratio)
A clean area chart with a filled region between the data line and the x-axis baseline. The fill should be semi-transparent to allow grid lines to show through slightly. The line defining the top of the area should be clearly visible. Axes should be properly labeled, and a subtle grid should aid in reading values.
