chart.js

问题 I have two react components. In which one of the components processes the CSV data using Papa Parse and another one renders the data table. I am using the first component to parse and send the data to the second component using this.props. Here, I'm using the Jquery data table to render the CSV data in the web. Problem is I'm unable to render the data inside the data table using this.props. (this issue has been resolved by @drew-reese) Also is it possible to render graph as defaultContent API

问题 I want to add an image inside the doughnut you can see my doughnut here I already tried by using background-image:url(image.png) but is there any way to do it. 回答1: Technically, it's not possible to add images in Charts. However, you can easily work with that by adding an image as a background for chart container. I.e.: #chartdiv { width: 210px; height: 210px; margin: 0 auto; background: transparent url(YourImage) no-repeat center 70px; } 来源： https://stackoverflow.com/questions/45349113/how

问题 I've scoured the bar chart and event docs (which I find a bit confusing) and I've been unable to figure out how to act on a mousein and mouseout event when hovering over a Bar chart's bars (not the legend!). Currently the closest I've been able to come is utilizing the callback on the tooltip like so: options.tooltips = { backgroundColor: 'rgba(0,0,0,0)', fontColor: 'rgba(0,0,0,0)', callbacks: { label: function (tooltipItem) { // flipping a bool here } } }; This solution doesn't work well

问题 I have problem with chartJS. I cannot add border around chart, yAxis unit title, and yAxis labelString with element. I'm using react with typescript. I can add only string to labelString. You can see what I want do do on screen and on another screen you can see what I actualy have. Is there any options in chart.js@2.7.1 to add these elements? First image is my goal. Second is actual. @edit This is my chartOptions file. I just pass arguments in function to get these options. import * as Chart
