Sometimes aggregating is a problem, this can be solved by filtering. This can be done while benchmarking using the `--set` parameter (e.g. `--set encoding=ascii`) or by filtering results afterwards using tools such as `sed` or `grep`. In the `sed` case be sure to keep the first line since that contains the header information. ```console -$ cat scatter.csv | sed -E '1p;/([^,]+, ){3}128,/!d' | Rscript benchmark/scatter.R --xaxis chunk --category encoding --plot scatter-plot.png --log - -chunk encoding mean confidence.interval - 16 ascii 701285.96 21233.982 - 16 base64-ascii 107719.07 3339.439 - 16 base64-utf8 72966.95 2438.448 - 16 utf8 475340.84 17685.450 - 64 ascii 2554105.08 87067.132 - 64 base64-ascii 330120.32 8551.707 - 64 base64-utf8 249693.19 8990.493 - 64 utf8 1128671.90 48433.862 - 256 ascii 4841070.04 181620.768 - 256 base64-ascii 849545.53 29931.656 - 256 base64-utf8 809629.89 33773.496 - 256 utf8 1489525.15 49616.334 - 1024 ascii 4931512.12 165402.805 - 1024 base64-ascii 863933.22 27766.982 - 1024 base64-utf8 827093.97 24376.522 - 1024 utf8 1487176.43 50128.721 +$ cat scatter.csv | sed -E '1p;/([^,]+, ){3}128,/!d' | Rscript benchmark/scatter.R --xaxis chunkLen --category encoding --plot scatter-plot.png --log + +chunkLen encoding rate confidence.interval + 16 ascii 1302078.5 71692.27 + 16 base64-ascii 338669.1 15159.54 + 16 base64-utf8 281904.2 20326.75 + 16 utf16le 1381515.5 58533.61 + 16 utf8 831183.2 33631.01 + 64 ascii 4363402.8 224030.00 + 64 base64-ascii 1036825.9 48644.72 + 64 base64-utf8 780059.3 60994.98 + 64 utf16le 3900749.5 158366.84 + 64 utf8 1723710.6 80665.65 + 256 ascii 8472896.1 511822.51 + 256 base64-ascii 2215884.6 104347.53 + 256 base64-utf8 1996230.3 131778.47 + 256 utf16le 5824147.6 234550.82 + 256 utf8 2019428.8 100913.36 + 1024 ascii 8340189.4 598855.08 + 1024 base64-ascii 2201316.2 111777.68 + 1024 base64-utf8 2002272.9 128843.11 + 1024 utf16le 5789281.7 240642.77 + 1024 utf8 2025551.2 81770.69 ``` ![compare tool boxplot](doc_img/scatter-plot.png) -- cgit v1.2.3
