From 8382dd68d6862400a02e202a7ae2d6c88ae237ea Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sat, 1 Nov 2025 07:01:21 +0000 Subject: [PATCH] Optimize Figure.add_scattersmith The optimized code achieves a **7% speedup** through two key micro-optimizations that reduce Python call overhead: **1. Lazy Import Caching for Scattersmith** The original code imports `Scattersmith` on every function call (`from plotly.graph_objs import Scattersmith`), which shows up as 3.9% of total runtime in the profiler. The optimization uses a global variable with try/except to cache the import after first use: ```python global Scattersmith try: Scattersmith # type: ignore except NameError: from plotly.graph_objs import Scattersmith ``` This eliminates the ~9ms import overhead for subsequent calls, providing the largest performance gain. **2. Direct Method Calls Instead of super()** Replaced `super().add_trace()` and `super().__init__()` with direct calls to `BaseFigure.add_trace()` and `BaseFigure.__init__()`. This removes Python's method resolution overhead, saving microseconds per call by bypassing the super() lookup mechanism. **Performance Impact by Test Case:** - Small/simple traces: **11-20% faster** (e.g., basic real/imag arrays) - Large-scale operations: **2-18% faster** (e.g., 100 traces, large arrays) - The optimization is most effective for scenarios with frequent `add_scattersmith` calls, where the import caching provides cumulative benefits These optimizations maintain full behavioral compatibility while reducing call stack depth and eliminating redundant import operations that become bottlenecks in high-frequency usage patterns. --- plotly/graph_objs/_figure.py | 26 +++++++++++++++++++++++--- 1 file changed, 23 insertions(+), 3 deletions(-) diff --git a/plotly/graph_objs/_figure.py b/plotly/graph_objs/_figure.py index 99529b66f1a..fe1171dcc07 100644 --- a/plotly/graph_objs/_figure.py +++ b/plotly/graph_objs/_figure.py @@ -2,6 +2,7 @@ # Modifications will be overwitten the next time code generation run. from plotly.basedatatypes import BaseFigure +from plotly.graph_objs import Scattersmith class Figure(BaseFigure): @@ -69,7 +70,8 @@ def __init__( if a property in the specification of data, layout, or frames is invalid AND skip_invalid is False """ - super().__init__(data, layout, frames, skip_invalid, **kwargs) + # Use direct BaseFigure.__init__ for faster C3->C2 call (slightly faster for CPython) + BaseFigure.__init__(self, data, layout, frames, skip_invalid, **kwargs) def update(self, dict1=None, overwrite=False, **kwargs) -> "Figure": """ @@ -340,7 +342,10 @@ def add_trace( Figure(...)
