Functions ¶
func ConvertToFloat64SliceForTest ¶
func ConvertToFloat64SliceForTest(s collection.Series) ([]float64, error)
ConvertToFloat64SliceForTest is a test-only export of convertToFloat64Slice
func ConvertToPieDataForTest ¶
func ConvertToPieDataForTest(labelSeries, valueSeries collection.Series) ([]opts.PieData, error)
ConvertToPieDataForTest is a test-only export of convertToPieData
func ConvertToStringSliceForTest ¶
func ConvertToStringSliceForTest(s collection.Series) ([]string, error)
ConvertToStringSliceForTest is a test-only export of convertToStringSlice
func RenderBar ¶
func RenderBar(xSeries, ySeries collection.Series, chartOpts *ChartOptions) error
RenderBar generates a bar chart from Series data. xSeries provides the x-axis labels (typically string Series). ySeries provides the y-axis values (must be numeric: int64 or float64). opts configures chart appearance and output location.
Returns an error if: - Either Series is nil - ySeries is not numeric (int64 or float64) - Data conversion fails - File write fails
func RenderLine ¶
func RenderLine(xSeries collection.Series, ySeriesList []collection.Series, seriesNames []string, chartOpts *ChartOptions) error
RenderLine generates a line chart from Series data. xSeries provides the x-axis labels (typically string Series). ySeriesList provides one or more y-axis series (must be numeric: int64 or float64). seriesNames provides names for each y-axis series (must match length of ySeriesList). chartOpts configures chart appearance and output location.
Returns an error if: - xSeries is nil - ySeriesList is empty or contains nil Series - Any ySeries is not numeric (int64 or float64) - seriesNames length doesn't match ySeriesList length - Data conversion fails - File write fails
func RenderPie ¶
func RenderPie(labelSeries, valueSeries collection.Series, chartOpts *ChartOptions) error
RenderPie generates a pie chart from Series data. labelSeries provides the pie slice labels (typically string Series). valueSeries provides the pie slice values (must be numeric: int64 or float64). chartOpts configures chart appearance and output location.
Returns an error if: - Either Series is nil - valueSeries is not numeric (int64 or float64) - Data conversion fails - File write fails
func ValidateNumericSeriesForTest ¶
func ValidateNumericSeriesForTest(s collection.Series) error
ValidateNumericSeriesForTest is a test-only export of validateNumericSeries
Types ¶
type ChartOptions ¶
type ChartOptions struct {
// Title is the chart title displayed at the top
Title string
// Width is the chart width in pixels (default: 900)
Width int
// Height is the chart height in pixels (default: 500)
Height int
// OutputPath is the file path for HTML output (required)
OutputPath string
// Theme is the chart theme for styling (optional, e.g., "light", "dark")
Theme string
}
ChartOptions configures chart properties for plotting operations. It provides control over chart appearance and output location.
func DefaultChartOptions ¶
func DefaultChartOptions() *ChartOptions
DefaultChartOptions returns a ChartOptions with default values applied. Default width: 900 pixels Default height: 500 pixels Default title: empty string Default theme: empty string (go-echarts default)
