Topic: Chart.js DataSet bug

ak.leimrey pro asked 6 years ago

  So, I have the following issue. I have two data sets, that look like this... public chartDatasets:Array<any> = [ { data: [65, 59, 80, 81, 56, 55, 40], label: 'My First dataset' }, { data: [28, 48, 40, 19, 86, 27, 90], label: 'My Second dataset' } ]; So far so good. But when I simply have only  one set of data like this... public chartDatasets:Array<any> = [ { data: [65, 59, 80, 81, 56, 55, 40], label: 'My First dataset' } ]; While this shouldn't be the case, the last month reveices no value. However, if I now add another value in my data set by simply adding a zero.   public chartDatasets:Array<any> = [ { data: [65, 59, 80, 81, 56, 55, 40, 0], label: 'My First dataset' } ]; The missing one is suddenly back.

Dear ak.leimrey, If you want to hide the second dataset, you have to set it as an empty array. Do not remove it from code. The only way to hide the second dataset, is to set is as an empty array. Let me know, if you understood me. Best Regards, Damian

Sorry for the late response, as I have been on vacation. The issue with setting an empty array is, that the legend/icon for that dataset is still being rendered and that chart.js still attempts to render it.

And I just did another test. The whole issue doesn't appear to pop up with the horizontal bar chart, only with the vertical one.

Is there a possibility to send me your project without node_modules directory? I would debug it, because for me, everything is working just fine. My mail: d.gemza@mdbootstrap.com Best Regards, Damian

It works now. deleted the node-modules and installed everything again. But now I have an unrelated question to chart.js. How do I manage that values are shown on top of the bars instead only by scrolling over?
