I'm trying to display data from laravel backend into Vue3 (vue-google-charts), but I didn't find any resources
this is a sample if my json data comming from backend
[
{
interest_oid: 1,
total_cards: 2
},
{
interest_oid: 3,
total_cards: 1
},
{
interest_oid: 5,
total_cards: 2
},
{
interest_oid: 2,
total_cards: 1
},
{
interest_oid: 4,
total_cards: 1
},
{
interest_oid: 8,
total_cards: 1
}
]
i want to display the data in GChart of type "CulomnChart" like this one
this is my Vue component
<div class="col-lg-6">
<GChart
type="ColumnChart"
:data="chartData"
:options="chartOptions"
style="height: 100%"/>
</div>
import {GChart} from "vue-google-charts";
export default {
components: {
GChart
},
props: {
contacts_per_interests: Array,
},
data() {
return {
chartData: this.contacts_per_interests,
chartOptions: {
width: 500,
height: 300,
chart: {
title: 'Company Performance',
subtitle: 'Sales, Expenses, and Profit: 2014-2017',
}
}
}
}
}
but it's display "× Table has no columns" any resources or suggestions please?
Your contacts_per_interests
array should be look like this:
[
['interest_oid', 'total_cards'],
[1, 2],
[3, 1],
[5, 2],
[2, 1],
[4, 1],
[8, 1],
]
Adjust accordingly. Like that:
$json = '[
{
"interest_oid": 1,
"total_cards": 2
},
{
"interest_oid": 3,
"total_cards": 1
},
{
"interest_oid": 5,
"total_cards": 2
},
{
"interest_oid": 2,
"total_cards": 1
},
{
"interest_oid": 4,
"total_cards": 1
},
{
"interest_oid": 8,
"total_cards": 1
}
]';
$jsonArr = json_decode($json);
$array = [['interest_oid', 'total_cards']];
foreach ($jsonArr as $item) {
array_push($array, [$item->interest_oid, $item->total_cards]);
}
