Custom Graph リファレンス
Custom Graph で利用可能な Geometry と Statistics の一覧です。各項目の詳細は、レイヤー設定内のヘルプボタン（?）で確認できます。
テーブル内の Description はアプリ UI の表記と一致させるため英語で記載しています。
Geometry（形状）
| Geometry | Description |
|---|---|
| Point (Scatter) | Displays data as individual points. |
| Line | Connects data points with lines. |
| Bar | Vertical bars for categorical data. Use Fill (not Color) to change bar color. |
| Area | Filled area under line. |
| Tile (Heatmap) | Grid of colored cells. Use Fill to set cell colors. |
| Step (Kaplan-Meier) | Stair-step line pattern. Used for Kaplan-Meier curves and ECDF. |
| Ribbon (Confidence Band) | Shaded area between ymin and ymax (confidence bands). |
| Error Bar | Error bars showing ymin to ymax range with caps. |
| Vertical Line (Reference) | Fixed vertical reference line. Configure style in the layer settings. |
| Horizontal Line (Reference) | Fixed horizontal reference line. Configure style in the layer settings. |
| Contour | Draws a curve from a series of points. Used for Cook's distance contours in regression diagnostics. |
| Density 2D | 2D kernel density estimation as contour lines. For 1D density curves, use the Density (KDE) statistic. |
Statistics（統計変換）
| Statistics | Description |
|---|---|
| Identity (No transformation) | Passes data through without transformation. |
| Bin (Histogram) | Groups numeric data into bins and counts occurrences. |
| Time Bin (Datetime Histogram) | Groups datetime data into time intervals. |
| Smooth (Regression) | Fits a smoothing curve (linear regression or LOESS). |
| Count (Aggregation) | Counts occurrences for each X value. |
| Density (KDE) | Estimates probability density using kernel density estimation. |
| Summary (Aggregation) | Aggregates Y values by X using mean, sum, median, min, max, standard deviation, or variance. |
| Survival (Kaplan-Meier) | Computes Kaplan-Meier survival estimates. |
| X Mean | Calculates the mean of X values. Use with vline geom to draw a vertical reference line. |
| X Median | Calculates the median of X values. Use with vline geom to draw a vertical reference line. |
| Y Mean | Calculates the mean of Y values. Use with hline geom to draw a horizontal reference line. |
| Cumulative Sum (Pareto) | Computes cumulative sum of Y values. Combine with Sort and Bar + Line to create Pareto charts. |
| Sort (Pareto) | Sorts data by Y values in descending order. Combine with Cumulative Sum to create Pareto charts. |
| ECDF (Empirical CDF) | Computes empirical cumulative distribution function. |
| QQ (Normal Q-Q Plot) | Computes quantiles for normal Q-Q plot. |
| Transform (Linear) | Applies linear transformation (multiply and add) to Y values. |
