I have difficult situation with updates dynamically data on charts. I created vue component that must render analytics from axios. There are several functions (methods) which parse arrived jsons from several API.
I created draw() - method for render every charts.
draw() {
if (this.mychart) {
this.mychart.destroy();
}
const ctx = document.getElementById('main-chart');
this.mychart = new Chart(ctx,
{
type: 'line',
data: {
labels: this.labels,
datasets: this.datacollection
},
options: {
legend: {
display: true,
position: 'bottom',
},
responsive: true,
scales: {
xAxes: [{
type: "time",
display: true,
scaleLabel: {
display: false,
},
ticks: {
major: {
fontStyle: "bold",
fontColor: "#FF0000"
}
}
}],
yAxes: [
{
id: 'y1',
type: 'linear',
position: 'left',
display: false
},
{
id: 'y2',
type: 'linear',
position: 'right',
display: false
},
{
id: 'y3',
type: 'linear',
position: 'left',
display: false
},
{
id: 'y4',
type: 'linear',
position: 'right',
display: false
},
{
id: 'y5',
type: 'linear',
position: 'left',
display: false
},
{
display: false,
gridLines: {
display: false
},
scaleLabel: {
display: true,
labelString: this.labelY
},
ticks: {
min: 0, // it is for ignoring negative step.
beginAtZero: true,
stepSize: 100
}
}]
}
}
});
},
All operations for calculating (parsing) data I do in mounted hook.
Also added in mounted hook nextTick() for delay render charts before data finish parsing.
async mounted() {
await this.loadIncomings(this.clubsId),
await this.loadAvgIncomings(this.clubsId),
await this.loadAvgPayments(this.clubsId),
await this.loadAvgSchedule(this.clubsId),
await this.loadTrainings(this.clubsId)
this.$nextTick(() => {
this.draw()
})
},
Now if internet connection is fast - charts render at one time. If you refresh page - you must waiting approximately 5-20 seconds for parsing data, and after this - appear graphs.
But, if I have bad connection, some axios requests finish with errors, and appear not all charts. And also I must waiting longer for parsing.
Finally, I have situation, that when I refresh page - several seconds page is empty. If connection is bad- not all charts render.
After this I have several questions:
1)How I could start render some finished data by chartjs in first seconds?
I mean not waiting when all data will come and calculated. I would like , that my charts render step by step. I want see y-axis and x-axis after I click refresh window.
Now I am using nextTick() but it is like 2nd step, where 1st step - is parsing data (may be I don't correctly understand)
I found some answers on similar question with render dynamic data, and people offered use chart.update(). But I can't get it. Where I must input this? If you look at my component, I have special method - draw(). If input in final string in my method with parsing data like : this.draw.mychart.update() or this.mychart.update() - I receive error in browser.
For example this function:
async loadIncomings(clubsId) {
try {
for (let clubId in clubsId) {
clubId = clubsId[clubId]
let dateFrom = this.dateFrom
let dateTo = this.dateTo
let groupBy = 'month'
let potential = true
let definitely = true
await this.$store.dispatch('loadIncomings', { clubId, dateFrom, dateTo, groupBy, potential, definitely }) // here I am waiting data from store (in store I use axios)
this.draftData = this.$store.state.incomings
if (this.labels.length === 0) {
this.getDates()
}
this.flagStartDate = true
await this.getIncomings(clubId)
this.flagStartDate = false
}
this.getIncomingsTotal()
this.draw.mychart.update() // here I am trying to refresh charts like advice from forums
} catch (e) {
console.error(e)
}
},
As you can see, this.getIncomingsTotal() - is last method for parsing data. After him, I am trying to update chart. But it's doesn't work.
Analytics-test.vue?b2a7:177 TypeError: Cannot read properties of undefined (reading 'update')
at VueComponent.loadIncomings (Analytics-test.vue?b2a7:175:1)
at async VueComponent.mounted (Analytics-test.vue?b2a7:498:1)
2)Also I use vue2-datepicker. I want set range dateFrom/dateTo. But when I choose date - charts doesn't change.
I have watch() , where I can monitoring dates dateFrom() and dateTo(). And also I am trying to rechart graphs with new dates - but nothing changes.
watch: {
dateFrom() {
console.log('dateFrom changed to', this.dateFrom)
this.draw()
},
dateTo() {
console.log('dateTo changed to', this.dateTo)
this.draw()
}
},
Under I show you my component:

I skipped code in other functions because it's doesn't matter. Situation with other the same.
so my problem is that I can't seem to make use of the "Mentions" functionality of tiptap inside a vuetify-nuxt project.
The original example can be found here
More useful info:
Example implementation from the tiptap github here
Similar question asked and not answered fully here
Similar question asked in the vuetify integration library here
To do that I'm trying to combine documentation examples.
I guess it goes wrong around the time I try to use "tippy", which is the css library used to display the popup that actually lists users to pick from (after the #), but I can't seem to understand the real issue.
So when I type # the keydown/up event listeners are functioning, but the tippy seems to not bind the popup successfully (it's not displayed), and the following error occurs:
Editor.vue?6cd8:204 Uncaught TypeError: Cannot read property '0' of undefined
at VueComponent.enterHandler (Editor.vue?6cd8:204)

at EditorView.someProp (index.es.js?f904:4766)
at editHandlers.keydown (index.es.js?f904:3298)
This is my tippy.js nuxt plugin:
import Vue from "vue";
import VueTippy, { TippyComponent } from "vue-tippy";
Vue.use(VueTippy, {
interactive: true,
theme: "light",
animateFill: false,
arrow: true,
arrowType: "round",
placement: "bottom",
trigger: "click",
// appendTo: () => document.getElementById("app")
});
Vue.component("tippy", TippyComponent);

I think you may need to install http module first like so:
npm install #nuxt/http
Then add the following to nuxt.config.js:
export default {
modules: [
'#nuxt/http',
],
http: {
// configure any options like
// baseURL: "https://jsonplaceholder.typicode.com"
}
}
Then you can make the calls as you were in your code:
async fetch () {
this.posts = await this.$http.$get('/posts').then(posts => posts.slice(0, 20))
}
Is there anyone who can help me translate this into ionic-4?
async addTransaction() {
this.ref = this.db.list('transactions', ref => ref.orderByChild('month'));
this.ref.push(this.transaction).then(() => {
this.transaction = {
value: 0,
expense: false,
month: 0,
};
let toast = this.toastCtrl.create({
message: 'New transaction has been added!',
duration: 3000
});
toast.present();
});
}
Please refer to the doc first. - https://ionicframework.com/docs/api/toast
import { Component } from '#angular/core';
import { ToastController } from '#ionic/angular';
#Component({
selector: 'toast-example',
templateUrl: 'toast-example.html',
styleUrls: ['./toast-example.css'],
})
export class ToastExample {
constructor(public toastController: ToastController) {}
async presentToast() {
const toast = await this.toastController.create({
message: 'Your settings have been saved.',
duration: 2000
});
toast.present();
}
async presentToastWithOptions() {
const toast = await this.toastController.create({
header: 'Toast header',
message: 'Click to Close',
position: 'top',
buttons: [
{
side: 'start',
icon: 'star',
text: 'Favorite',
handler: () => {
console.log('Favorite clicked');
}
}, {

console.log('Cancel clicked');
}
}
]
});
toast.present();
}
}
i want to integrate this toast only if axios post is executed. i placed it like that and it's shown up even if my post axios function is not working.
how can i fix that ?
My code:
methods: {
addRinvoice: function () {
const toast = swal.mixin({
toast: true,
position: 'top-end',
showConfirmButton: false,
timer: 9000
});
axios.post('/addrinvoice', this.rinvoice)
.then(response => {
toast({
type: 'success',
title: 'Invoice added in Database'
}),
console.log(response.data);
if (response.data.etat) {
this.rinvoice = {
id: 0,
amount: response.data.etat.amount,
};}})
.catch(error => {
console.log('errors: ', error)
}) },
Just put your call invoking the toast method inside your then() method:
methods: {
addRinvoice: function () {
axios.post('/addrinvoice', this.rinvoice)
.then(response => {
const toast = swal.mixin({
toast: true,
position: 'top-end',
showConfirmButton: false,
timer: 9000
});
