However, predominant visualization techniques suffer from a high cognitive load due to visual clutter. We propose Colorslope, a hybrid of Tufte\u2019s slope graph and temporal heatmap, to depict ranks over time in one graph while maintaining an overview and details with scalability. Colorslope combines both canonical visualization methods\u2019 complementary benefits: depicting overall trends and enabling the estimation of detailed values. We evaluated the efficacy and effectiveness of Colorslope by comparing it with a standard bump chart and temporal heatmap on various data sizes. We conclude that Colorslope contributes by (1) allowing users to identify extremes of the data and rate of change effectively in a relatively large number of series; (2) allowing the visualization to have better scalability in a larger amount of data (e.g., 30 \u223c 50) than a bump chart; and (3) allowing users to gain a better estimate of data values than a heatmap. For a certain size of ranks over time data, Colorslope provides an alternative solution to visualize multiple time series simultaneously that provides both an overview and a certain level of detail.<\/jats:p>","DOI":"10.1007\/s44267-023-00008-9","type":"journal-article","created":{"date-parts":[[2023,6,1]],"date-time":"2023-06-01T03:37:56Z","timestamp":1685590676000},"update-policy":"https:\/\/linproxy.fan.workers.dev:443\/https\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Colorslope: a balanced visualization of overview and details on ranks over time"],"prefix":"10.1007","volume":"1","author":[{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0002-1492-797X","authenticated-orcid":false,"given":"Hao","family":"Wang","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0002-1092-6929","authenticated-orcid":false,"given":"Xingyu","family":"Jiang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0001-9827-4293","authenticated-orcid":false,"given":"Apurva","family":"Nagarajan","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0003-1007-5148","authenticated-orcid":false,"given":"Xiaolei","family":"Guo","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0001-9724-5327","authenticated-orcid":false,"given":"Lu","family":"Ding","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0003-2104-0768","authenticated-orcid":false,"given":"Dayu","family":"Wan","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0002-0316-8365","authenticated-orcid":false,"given":"Junhan","family":"Zhao","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0001-6705-3535","authenticated-orcid":false,"given":"Yingjie","family":"Chen","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2023,6,1]]},"reference":[{"issue":"7","key":"8_CR1","doi-asserted-by":"publisher","first-page":"2505","DOI":"10.1109\/TVCG.2018.2829750","volume":"25","author":"B.
