👍:0 I would use a directive and it looks like there’s already one out there for chart.js and AngularJS. This way you can easily set up the data for each chart. How to set Json data to chart.js bar Bootstrap ui+angular chart: is it possible to disable graph's auto refreshing?
0👍 ✅ A quick fix for this can be to add a leading space to the Y-Labels. You can do this by editing the scaleLabel template to include the space scaleLabel: ” <%= value%>” just pass this in as one of the options when creating the graph ChartJS Legend Not Lining Up
0👍 ✅ var chartLegend = “<ul style=\”list-style-type: none; padding: 0\”>”; for(var i = 0; i < chartDatas.datasets.length; i++) { chartLegend += “<li><span style=\”background-color:” + chartDatas.datasets[i].pointColor + “;height:20px; width:20px; display:inline-table; margin:5px;\”></span>” + chartDatas.datasets[i].label + “</li>” } demo How to add simple option to chartjs correctly
👍:0 The option referenced in the (question) comments is from PR 521 that has not been merged into the main branch yet. This was later made into a PR 897, which too is yet to be merged. So, if you want this feature, you should be using code from either of the above. Here is … Read more
👍:0 You need to do an update() after updating the labels. And you have to update the labels on the chart object. window.days = function() { myLineChart.scale.xLabels = [“01”, “02”, “03”, “04”, “05”, “06”, “07”]; // Days myLineChart.update(); } Fiddle – https://jsfiddle.net/rxoLjd92/ Not able to set dataset value in chart.js
0👍 ✅ You can just replace the jQuery functions in the question you linked to by their Javascript equivalents. 1. var ctx = jQuery("#LineChart").get(0).getContext("2d"); becomes var ctx = document.getElementById("LineChart").getContext("2d"); 2. SPOn = jQuery(‘.sp’).hasClass(‘enabled’); NCOn = jQuery(‘.nc’).hasClass(‘enabled’); SPAOn = jQuery(‘.sp-avg’).hasClass(‘enabled’); NCAOn = jQuery(‘.nc-avg’).hasClass(‘enabled’); becomes SPOn = document.getElementsByClassName(‘sp’)[0].className.indexOf(‘enabled’) != -1; NCOn = document.getElementsByClassName(‘nc’)[0].className.indexOf(‘enabled’) != -1; SPAOn = … Read more
0👍 ✅ You can use the toDataURL() to make the canvas into an image (and you could use media specific CSS to hide the canvas and swap in the img with src as the Data URL when printing) Remember to wait for the animation to end before generating the data URI or you end up … Read more
0👍 ✅ In generateDataSetsFromTable(), move your dataset creation outside of the tr loop (rows.each) function generateDataSetsFromTable() { var data; var datasets = []; var rows = jQuery(“tr”); var data = []; rows.each(function(index){ if (index != 0) // we dont need first row of table { var cols = $(this).find(“td”); cols.each(function(innerIndex){ if (innerIndex!=0) // we dont … Read more
0👍 ✅ Instead of setting the dataset property to an empty object, just don’t include it in the dataset at all. So data = { labels: chartlabel, datasets: [SP, NC, SPA] }; becomes data = { labels: chartlabel, datasets: [] }; if (SP.label !== undefined) data.datasets.push(SP) if (NC.label !== undefined) data.datasets.push(NC) if (SPA.label !== undefined) … Read more
0👍 ✅ You need to store the current state of the data for each series before blanking or resetting the corresponding dataset in enableCheck. Then use this saved state. Example for the SP dataset Initialization of the state (spData). I also initialize the dataset (SP) var spData = [1, 2, 3, 4, 5, 6, 7, … Read more
