This may be a JSON or JS issue but I can't find a soution yet. My single series bar chart shows different colours for the first 30 data points but no colour after that. Any suggestions welcome! [image] var date = new Date(); var mon = date.getMonth() + 1; var x = 0; var dv = 0; var t = [0,0,0]; var title = ["","",""] var myData = msg.payload; global.set("myData", myData); var chart = [{ "series":["Gate"], "data": [new Array(64)], "labels":[""] }, { "series": ["Site"], "data": [new Array(64).fill(0)], "labels": [""] }, { "series": ["Total"], "data": [new Array(64).fill(0)], "labels": [""] }] for (let m = 5; m <= mon; m++) { for (let j = 0; j < 2; j++) { //var m=6; var mo = m.toString(); for (var i = 0; i < 32; i++) { x = ((m - 5) * 31) + i; // x = i; dv = myData[j][mo][i] || 0; chart[j].data[0][x] = dv; t[j] = t[j] + dv; t[2] = t[2] + dv; chart[j].labels[x] = mo + "." + i.toString(); chart[2].data[0][x] = chart[2].data[0][x] + chart[j].data[0][x]; chart[2].labels[x] = mo + "." + i.toString(); } } } title[0] = "Gate " + t[0].toLocaleString() + " Gal"; title[1] = "Site " + t[1].toLocaleString() + " Gal"; title[2] = "Total " + t[2].toLocaleString() + " Gal"; return [{ title: title[0], payload: [chart[0]] }, {title: title[1], payload: [chart[1]]}, {title: title[2], payload: [chart[2]]}, {payload: t}]

[image] How to specify colours for bar chart Dashboard The Chart node editor dialog gives 9 colours. There are a further 24 colours specified somewhere in the background, but once they are used up the bars on a chart are uncoloured. [Untitled 5] Can the chart be persuaded to repeat colours for the 34th bar onwards? Alternatively can I define extra colours? I found this on github where the extra 24 are specified, but grep -R baseColours .node-red on my computer doesn't find anything. [Untitled 4]

Thanks! I did see that one, but didn't find a solution...

That thread includes a shell script that repeats the chart colours. It works for me on Linux
