how to show multiple data labels on react highchart line chart?

i want to show below data (sample data from my api) on react highchart line chart. but i am confuse how to prepare this data. the chart should be look alike, at Aaxis all assignments name and at y axis if 4 assignment name then look at data each object have values array. so 4 assignment names means 4 charts with multiple data labels. look at below screen shot. first image is what my chart should look alike. the second screenshot is how my chart giving error data is not loading.i am also attaching codesandbox link. the data is too much i have total 30+ assignments names with array of datalabels but right now i am attaching only 4.
codesandbox link : https://codesandbox.io/s/customizable-react-dashboard-with-chart-fork-forked-15rfpq?file=/src/LineHighchart.js
my sample Data:
const data ={"data":[{"assignment_name":"assignment for oliver","0":26,"1":1,"2":70,"3":80,"4":100,"5":10,"6":0,"7":0},{"assignment_name":"assignment","0":25,"1":0,"2":19,"3":35,"4":310,"5":0,"6":0,"7":0},{"assignment_name":"assignment2","0":27,"1":20,"2":10,"3":30,"4":50,"5":90,"6":0,"7":0},
{"assignment_name":"assignment2","0":29,"1":0,"2":10,"3":0,"4":30,"5":0,"6":60,"7":10},
]}

I am not familiar with the react wrapper for Highcharts, but here is a plain vanilla Highcharts object to show a line graph with two series and five data points, which might help you dig further:
{
"chart": {
"height": 436
},
"xAxis": {
"categories": [
"2019-12-30",
"2020-01-06",
"2020-01-13",
"2020-01-20",
"2020-01-27",
],
"title": {
"text": "Week",
}
},
"series": [{
"name": "Count",
"type": "line",
"data": [ 6, 9, 7, 6, 5 ]
}, {
"name": "Slope",
"type": "spline",
"data": [ 5.9, 6.23, 6.57, 6.9, 7.23 ]
}
]
}
UPDATE:
Here is the answer for your comment question: "can u make array of object from my given data and then give that variable to series":
const data ={
"data": [
{"assignment_name":"assignment for oliver",
"0":26,"1":1,"2":70,"3":80,"4":100,"5":10,"6":0,"7":0},
{"assignment_name":"assignment",
"0":25,"1":0,"2":19,"3":35,"4":310,"5":0,"6":0,"7":0},
{"assignment_name":"assignment2",
"0":27,"1":20,"2":10,"3":30,"4":50,"5":90,"6":0,"7":0},
{"assignment_name":"assignment2",
"0":29,"1":0,"2":10,"3":0,"4":30,"5":0,"6":60,"7":10},
]
};
let categories = Object.keys(data.data[0]).filter(key => key.match(/^\d+$/));
let series = data.data.map(obj => {
return {
name: obj.assignment_name,
tyle: 'line',
data: categories.map(key => obj[key])
}
});
let chartObj = {
"chart": {
"height": 436
},
"xAxis": {
"categories": categories,
"title": {
"text": "Assignments",
}
},
"series": series
};
console.log(chartObj);

Plotly JS crossfilter on id with multiple graphs

I am trying to build a dashboard with multiple plotly graphs in Javascript. I would like to implement a crossfilter function within the charts where the selected data in a graph will be highlighted in the other graphs on the same id. Please see an example below:
Dataset Graph 1:
[{
"id": "1",
"ItemWidth" : 545,
"ItemLength" : 234
},
{
"id": "2",
"ItemWidth" : 33,
"ItemLength" : 2234234
}]
Dataset Graph 2:
[{
"id": "1",
"ItemSold" : 44,
"AnotherAtt" : 567
},
{
"id": "2",
"ItemSold" : 1213,
"AnotherAtt" : 656
}]
As you can see the datasets are different but they have the same id. I would like to know how to implement a crossfilter on id based on the datasets within multiple graphs where they share the same id.
Any help and advise is appreciated.

Nested JSON Objects with Dimple.js

I'm attempting to create a stacked bar chart with Dimple.JS and D3. However, the JSON file I wish to use with this particular visualization involves nested JSON objects (below). The stacked bar chart I wish to create has the channel category as its x-axis, with the y axis to be the aggregate count of the different locations (with each location as a 'stack'). Here is the original data:
[{
"channel": "politics",
"locations":
[{
"name":"usa",
"count" : 1454
},
{
"name":"mexico",
"count":3543
},
{
"name":"antarctica",
"count":4352
}]
},
{
"channel": "economics",
"locations":
[{
"name":"usa",
"count" : 12431
},
{
"name":"mexico",
"count":314
},
{
"name":"china",
"count":2321
}]
}]
I've flattened the above into the JSON below, but I am having trouble using Dimple's .addSeries() method to create the stack.
[
{
"channel": "politics",
"locations[0].name": "usa",
"locations[0].count": 1454,
"locations[1].name": "mexico",
"locations[1].count": 3543,
"locations[2].name": "antarctica",
"locations[2].count": 4352
},
{
"channel": "economics",
"locations[0].name": "usa",
"locations[0].count": 12431,
"locations[1].name": "mexico",
"locations[1].count": 314,
"locations[2].name": "china",
"locations[2].count": 2321
}
]
My question is this: how can Dimple support either this data encoded in this particular JSON file? Most samples use CSV and TSV files, but I unfortunately have the limit of using only JSON files.

Dimple can't use nested data. You'll have to flatten it on the client side so there's a single JSON object for each intersection of channel/location. Here's an example of how to do that with Underscore.js :
var chartData = _.chain(data)
.map(function(row, index){
// for each original row, return a new row for each location
return _.map(row.locations, function(location){
return {
'channel' : row.channel,
'name' : location.name,
'count' : location.count
};
});
})
.flatten()
.value();
(For every row in the original data set, it will return three rows, one for each location. This will return an array of nested arrays, so it calls flatten to make the whole array 1 level deep.)
Here's a jsBin showing that in action : http://jsbin.com/nuvihu/edit?html,js,output
(output):
If this helps, here is what the data ended up looking like :
[{"channel":"politics","name":"usa","count":1454},{"channel":"politics","name":"mexico","count":3543},{"channel":"politics","name":"antarctica","count":4352},{"channel":"economics","name":"usa","count":12431},{"channel":"economics","name":"mexico","count":314},{"channel":"economics","name":"china","count":2321}]

How can I draw a semantic differential chart in Fusionchart?

I am looking for a chart solution of an semantic differential like in this pictures.
But I found only line charts like this one:
fiddle
How can I change this chart into ones like this below.
Maybe in this part?
"trendlines": [
{
"line": [
{
"startvalue": "17022",
"color": "#6baa01",
"valueOnRight": "1",
"displayvalue": "Average"
}
]
}

Javascript FLOT Combined Bar & Line Chart with x-axis as string

I have a bar graph where the x axis is a string, so I need to use a ticks array, I also need to be able to specify the colour of each bar and to also plot a line in the same graph.
The following is the code I have now which has been through many alterations to try and make it work, but I am now stuck.
I cannot get this to display the graph at all, here it is on jsfiddle: http://jsfiddle.net/9x7aJ/4102/
Any help would be appreciated as I have spent the best part of today on trying to solve this.
var fdat = [
{
"color": "#6ECFF6",
"data": [[0,114]]
},
{
"color": "#7BCDC8",
"data": [[1,96]]
},
{
"color": "#FDC68A",
"data": [[2,94]]
}
]
var data = [
{label: "d1", data:fdat, bars: {show: true}},
{label: "d2",data:fdat, lines: {show: true}, points:{show:true}}
];
var opts = {xaxis: {ticks:[[0,"Text 1"], [1,"Text 2"], [2,"Text 3"]]}};
$.plot($("#placeholder"),data,opts);

You cannot have an object with different colors for each data point, data points have to be simple arrays. If you simplify your data to
var fdat = [
[0, 114],
[1, 96],
[2, 94]
]
the graph works (updated fiddle).
If your need different colors for each bar, create one data series for each bar.
