问题 How can i display different labels under each column and also have another label for the entire group? As you can see in the picture below i want to use fontawesome icons for each column but another label for the main group. I found other answers how to use fa icons but don't know how to position them under each bar. The trendlines which connect distinct columns are not so important but would be great if i can find out how to add them also. Also the chart needs to be scrollable as it can hold

问题 I have this graph: which is built in ChartJS, however, between 1pm and 5:30pm, there was no data. All I want the chart to do is display that there is no data, rather than joining the two points. Can this be done? In theory I have a new value every 5 seconds, but this could reduce, so I guess I would need to be able to set a tolerance of gaps to join vs gaps to show? ChartOptions shown below: myChart = new Chart(ctx, { type: 'line', data: { labels: timestamp, datasets: [{data: speed

问题 my plan is to display a temperature graph using chartJS that looks somewhat like the google one when you look up local weather. I am using data from openweathermap and would like to update the graph every 3 hours. Unfortunatly I wasn't able to find a solution that worked for me to pass the data i get from openweathermaps to the chart array and update it. In the documentation an update function is mentioned (http://www.chartjs.org/docs/latest/developers/updates.html) but I think I am too much

问题 I want to configure one chart to have a different timezone (for example I'm in utc+00 and want to display data in utc+01) Is there a way? according to docs I have to return a moment object, and then date displays according to moment global locale. 回答1: In the time configuration options specify parser as a function: scales: { xAxes: [{ type: 'time', time: { unit: 'hour', min: minDate, max: maxDate, displayFormats: { hour: 'HH' }, parser: function (utcMoment) { return utcMoment.utcOffset('+0100

问题 there. I use ChartJS and customise tooltip, but have issue with position first and last tooltip's. Look: I suppose that in order to fix the problem, I need to use the https://www.chartjs.org/docs/latest/configuration/tooltip.html#position-modes but, I cannot understand what the formula should be.

问题 I'm having a hard time making the labels in the y-axis responsive.I want the labels to move to multiple lines and have responsive font sizes when the space is not enough.I'm using the chart.js datalabels library for labelling on top of horizontalBar Graph.Also the labels are getting hidden due to the outer chart container. var chart = new Chart('ctx', { type: 'horizontalBar', data: { labels: ["Something something something", "blah blah..", "blah blah..","Something something something"],
