摘要
击球和保龄球被广泛认为是板球运动中的关键技能。传统上,板球运动依靠三个不同的指标来衡量保龄球的表现:平均保龄球命中率、保龄球手的击球率和经济率。虽然每种衡量标准都试图量化保龄球手的表现,但它们各自的范围都是独一无二的。研究人员曾多次尝试将这些指标整合成一个综合指数,对保龄球手进行排名。然而,整合过程不可避免地会导致个别指标失去其独特性。本文试图利用等高线图在二维平面上直观地展示这三个指标。为了更好地说明保龄球运动员之间在三个不同指标上的接近程度,本文对等高线图提出了一些改进建议。拟议的图形扩展利用了不同时代保龄球手的职业生涯统计数据,展示了保龄球风格是如何随着板球得分模式的变化而演变的。此外,还开发了一个 R 程序,以方便绘制上述图形扩展。
Visualizing bowling performance in cricket using contour plot
Batting and bowling are widely considered to be the pivotal skills in cricket. Traditionally, cricket has relied on three distinct metrics to measure bowling performance: the bowling average, the bowler's strike rate, and the economy rate. While each of these measures attempts to quantify the performance of bowlers, their respective scopes are unique. Researchers have made several attempts to integrate these measures into a composite index to rank bowlers. However, the integration process inevitably results in the loss of the individual metrics' distinct natures. This paper endeavours to visualize the three measures in a two-dimensional plane using a contour plot. To better illustrate the proximity amongst bowlers concerning the three distinct measures, a few improvements to the plot are proposed. The proposed graphical extension utilizes the career statistics of bowlers across different eras and demonstrates how the style of bowling has evolved as the scoring patterns in cricket change. Additionally, an R program has been developed to facilitate the drawing of said graphical extension.
