            chartjs-plugin-annotation box in Django app
            Asked 2022-Apr-11 at 16:32

            I have chartjs v2.9.3 in my Django app and it works great. Now I need to add a box to one of my charts using chartjs-plugin-annotation, and I've followed all the steps, but I can't get it to work. I've used chartjs-plugin-annotation v0.5.7 which is for v2.9.3. I get no errors in the console log. First, scripts with chart.js and plugins:



            Answered 2022-Apr-11 at 16:32

            This is because you putted the options in the place where they belong in V1 of the annotation plugin and the syntax too. For V0.5.7 the annotation options have to be placed in the root of the options and also all the annotations are an array instead of seperate objects:

            Answered 2022-Apr-08 at 08:08

            You are using a mismatch of versions. Version 2 of the datalabels plugin is for chart.js version 3 while you are using chart.js version 2. So you either need to update chart.js and the wrapper which does include breaking changes or you need to install version 1.0.0 of the datalabels plugin

            Seems like you are using typings in .js file.

            Update data of chartjs chart
            Asked 2022-Mar-14 at 12:46

            First of all, I would like to say that I'm a student learning programming for around a month, so expect to see many mistakes.

            I'm working on a website where I use a chart from the ChartJs library. The data used for this chart is taken through requests to a server. I am working on making requests to the server every X number of seconds, so the data displayed on the chart gets updated automatically without having to refresh or do anything.

            I would say I have most of it done, but I have a problem with ChartJs. I have the chart together with the request to server, all in one function which I then call on windows.onload. I have used setInterval to call this function every 5 seconds, and in practice this works, but I get this error :

            Uncaught Error: Canvas is already in use. Chart with ID '0' must be destroyed before the canvas can be reused.

            So I understand what is happening, I am trying to create the chart over and over again on the same canvas element, and that of course doesn't work. I have seen about the destroy() method and update() method, but I haven't been able to find a solution for my specific case. If anyone could tell me any ideas on how to do this in this case, I would really appreciate it. Here is the code:



            Answered 2021-Sep-15 at 16:55

            The first time you run your function, you're placing the chart (a.k.a "the returned value of new Chart()") inside the outterChart variable.

            If you instantiate that variable outside of your function (in this case, outside chartRender), its value will be preserved across multiple runs of the function, and you'll be able to choose whether or not to create the chart or just update it based on current value of outterChart.

            In principle:



            How to show a "total" sum label on the top of stacked bars
            Asked 2022-Feb-24 at 14:57

            I'd like each stacked bar to have their "total" label position just above the entire bar.

            I've managed to get the sum, but I'm having trouble positioning the label at the top.

            If you notice, the labels are positioned at the bottom:

            I've tried playing around with the anchor and offset properties, but I was unable to achieve the desired result.




            Answered 2022-Feb-24 at 14:57

            You need to change the formatter function to make it work.

            The total value shall appear on the top most value of the stacked bars only. The stacked bars however don't contain zero values nor values from hidden datasets. I ended up with the following solution that works but can probably be improved/simplified.



            How to hide label of specific data?, chartjs plugin datalabels
            Asked 2022-Feb-18 at 16:01

            I made a radial progress bar using the nested doughnut chart, the object works fine.

            I wanted to show the progress on a label, but the label became visible in the data I used as the background.

            q1:How can i hide the label i just use as background?

            q2:Do you think it is good to make progress bar using chartjs? (real time) I would be very happy if you could provide information about another alternative library.

            Answered 2022-Feb-18 at 16:01

            you can use the display callback to determine which labels are displayed

            if I follow correctly, you do not want labels to appear on the gray portion of the chart...?

            if so, only display the first value...



            How to change default label of each bubble in bubble chart using chartjs-plugin-datalabels

            I am trying to add labels to each bubble in the bubble chart using chartjs-plugin-datalabels. For each bubble, I want to show the label property of each object of data.dataset array

            If you update to chart.js V3 you can use the build in pointLabels and center them:



            Vue 3: Module '"../../node_modules/vue/dist/vue"' has no exported member
            Asked 2022-Jan-24 at 08:38

            After updating my npm packages, some of the imports from the 'vue' module started showing errors:

            TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'

            where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.

            What I've tried:

            • Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of TypeError: Object(...) is not a function errors in console and not rendering the app at all. In the terminal, some new warnings are introduced: "export 'X' (imported as '_X') was not found in 'vue' where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle.
            • Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
            • Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.

            Answered 2021-Aug-15 at 13:53

            That named exports from composition API are unavailable means that vue is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies and both lock file and node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.

            The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13 depends on vue-jest@3 which depends on vue@2.

            A possible solution is to upgrade @vue/cli-plugin-unit-jest to the latest version, next. The same likely applies to other @vue/cli-* packages because they have matching versions.
