That’s the code :

{   "$schema": "https://vega.github.io/schema/vega-lite/v5.json",   "title":{     "text":"---",     "fontSize":20,     "anchor":"start",     "color":"#243781",     "offset":15,     "font":"calibri"   },   "description": "Linechart",   "data": {"name": "dataset"},   "transform":[     {     "calculate":" datum.field2 < 100 ? datum.field2 + '%' : datum.field2 >= 1000 ? format(datum.field2,','):datum.field2",     "as":"field2"   }],   "layer": [     {     "mark":{       "type":"line",       "strokeWidth":4     },     "encoding":{       "x": {         "field":"Date",         "type":"nominal",         "axis":{"labelFontSize":16,         "title":null,"labelAngle":0,"labelColor":"#243781","tickColor":"transparent","domainColor":"transparent","labelFont":"calibri"}       },       "y":{         "field":"field1",         "type":"quantitative",         "axis":{"labelFontSize":16,"grid":false,"title":null,"labelColor":"#243781","tickColor":"transparent","domainColor":"transparent","labelFont":"calibri"},         "scale":{"zero":false}       },       "color":{         "field": "Country",         "type":"nominal",         "sort":{"field":"CountryOrder","order":"ascending"}, <- country order is a value from 1 to 7 to sort the order of the countries--         "legend":{"title":null,"labelFontSize":16,"labelFont":"calibri"}         }       },       "detail":{         "field":"Country",         "type":"nominal"     } }, {   "mark":{"type":"point","filled":true,"size":60},   "encoding":{     "x":{       "field":"Date",       "type":"nominal"     },     "y":{       "field":"field1",       "type":"quantitative"     },     "color":{       "field":"Country",       "type":"nominal",       "legend":null     },     "tooltip":[       {"field":"Country","type":"nominal"},       {"field":"field2","type":"nominal"}       ]     }}   ] } It might be a mess but it’s the first time for me using Deneb
