SAPUI5 line chart returning weird output

I am using northwind oData model and using the "SummaryByYear" model to create a line chart. The data looks as follows (for easier representation, only 4 entries are shown):
{
"results": [
{
"__metadata": {
"uri": "https://services.odata.org/V2/Northwind/Northwind.svc/Summary_of_Sales_by_Years(10248)",
"type": "NorthwindModel.Summary_of_Sales_by_Year"
},
"ShippedDate": "1996-07-16T00:00:00.000Z",
"OrderID": 10248,
"Subtotal": "440.00"
},
{
"__metadata": {
"uri": "https://services.odata.org/V2/Northwind/Northwind.svc/Summary_of_Sales_by_Years(10249)",
"type": "NorthwindModel.Summary_of_Sales_by_Year"
},
"ShippedDate": "1996-07-10T00:00:00.000Z",
"OrderID": 10249,
"Subtotal": "1863.40"
},
{
"__metadata": {
"uri": "https://services.odata.org/V2/Northwind/Northwind.svc/Summary_of_Sales_by_Years(10250)",
"type": "NorthwindModel.Summary_of_Sales_by_Year"
},
"ShippedDate": "1996-07-12T00:00:00.000Z",
"OrderID": 10250,
"Subtotal": "1552.60"
},
{
"__metadata": {
"uri": "https://services.odata.org/V2/Northwind/Northwind.svc/Summary_of_Sales_by_Years(10251)",
"type": "NorthwindModel.Summary_of_Sales_by_Year"
},
"ShippedDate": "1996-07-15T00:00:00.000Z",
"OrderID": 10251,
"Subtotal": "654.06"
}
]
}
following is the XML view for Chart:
<chart:ChartContainer id="chartContainer" showFullScreen="true" showZoom="false" title="Sales Summary (by Year)">
<chart:ChartContainerContent>
<chart:content>
<viz:VizFrame id="lineChart" width="auto" uiConfig="{applicationSet:'fiori'}">
</viz:VizFrame>
</chart:content>
</chart:ChartContainerContent>
</chart:ChartContainer>
and this is the controlles onInit function:
onInit: function () {
var northwind = this.getOwnerComponent().getModel("northwind");
var that = this;
northwind.read("/Summary_of_Sales_by_Years", {
method: "GET",
success: function (resp) {
resp["results"].forEach(item => {
item.Subtotal = item.Subtotal.toString().slice(0, -2)
});
var summaryByYear = new JSONModel({
"results": resp["results"]
})
var lineChart = that.getView().byId("lineChart");
lineChart.setVizType('line');
lineChart.setUiConfig({
applicationSet: 'fiori',
});
var oDataset = new FlattenedDataset({
dimensions: [{
axis: 1,
name: 'Year',
value: '{ShippedDate}',
datatype: "date"
}, ],
measures: [{
name: 'Subtotal',
value: '{Subtotal}',
}],
data: {
path: '/results',
},
});
lineChart.setDataset(oDataset);
lineChart.setModel(summaryByYear);
var feedValueAxis = new FeedItem({
uid: 'valueAxis',
type: 'Measure',
values: ['Subtotal'],
}),
feedCategoryAxis = new FeedItem({
uid: 'categoryAxis',
type: 'Dimension',
values: ['Year'],
});
lineChart.addFeed(feedValueAxis);
lineChart.addFeed(feedCategoryAxis);
lineChart.setVizProperties({
general: {
layout: {
padding: 0.04,
},
},
plotArea: {
window: {
start: 'firstDataPoint',
end: 'lastDataPoint'
}
},
valueAxis: {
label: {
formatString: 'axisFormat',
},
title: {
visible: false,
},
},
categoryAxis: {
title: {
visible: false,
},
},
plotArea: {
dataLabel: {
visible: true,
formatString: 'datalabelFormat',
style: {
color: null,
},
},
},
legend: {
title: {
visible: false,
},
},
title: {
visible: false,
text: 'Summary of Sales (by year)',
},
levels: ['month', 'day', 'year'],
interval: {
unit: ''
}
});
}
});
}
following is the result:
I am getting the date in raw timestamp format instead of year and month and also there are weird texts such as "5atalabelfor9at". What am I doing wrong here and please point me to the correct docs if I am missing some kind of config, thanks.

Echarts:My pie charts block my line chart while I'm intended to bind them together

How can I bind pie chart and line chart together rather than appear one by one? And the pie charts which appear later than line chart will block the line chart. Is there any chance the pie and line can appear together in the end?
The current situation is that
at the beginning,and then.
This is the JS code.

},
{

}
]
}
chart.setOption(option);
$.get('https://gist.githubusercontent.com/Linya-gzl/4d4f388e1b0e3d8e05c38f875b94a97c/raw/8c121acbfaf4aac9eccaf6b81cd1b3614203c185/demo1.json').done(function (data) {

I changed your code a bit in the series insertion part, by my opinion need inserting series completely because partial inserts sometimes cause problems with merging data. Also I fixed coordinate calculation, more correct way take the already calculated coordinates from line if they the same.

Highcharts limit the amount of items that will be displayed in categories on the yAxis

I have the following chart in Highcharts, I wanted to limit the amount of items that will be displayed on the yAxis, for example 7 items, which always show the first and last items of the variable categories.
$(function () {
var categories = ["Pos 01", "Pos 02", "Pos 03", "Pos 04", "Pos 05", "Pos 06", "Pos 07", "Pos 08", "Pos 09", "Pos 10", "Pos 11", "Pos 12", "Pos 13", "Pos 14", "Pos 15", "Pos 16", "Pos 17"];
var plan = [{x: 1534095420000, y:15},{x:1534097580000, y:14},{x:1534099020000,y:13},{x:1534119900000,y:12},{x:1534149780000,y:11},{x:1534174620000,y:10},{x:1534176420000,y:9},{x:1534189020000,y:8},{x:1534313940000,y:7},{x:1534317900000,y:6},{x:1534337700000,y:5},{x:1534373880000,y:4},{x:1534374120000,y:3},{x:1534375560000,y:2},
{x:1534377720000,y:1},{x:1534378200000,y:0},{x:1534378200000,y:0},{x:1534414200000,y:0},{x:1534414620000,y:1}];
var series =[{
name: "Plan",
id: "plan",
data: plan
}];
// Create the chart
window.chart = new Highcharts.Chart('container',{
colors: ["#7cb5ec"],
chart: {
type: "spline",
},
exporting: {
enabled: false
},
title: {
text: 'Graphic'
},
yAxis: {
categories: categories,
title: {

},
labels: {

},
},
xAxis: {

return this.series.yAxis.categories[this.point.y];
}
},

});
});

<div id="container" style="height: 600px; min-width: 500px"></div>

It can be done in many ways depending on a few things:
- what data do you have,
- how many ticks do you want to have,
- whether you want to display labels between ticks or on ticks,
- how do you want to display labels if a number of categories is not divisible by a number of ticks,
- whether you want to have equal gaps between ticks etc.
We can play with formatter function, categories, tickAmount property, yAxis.max property and many other things. But in most cases we will have to give up from setting categories ridigly.
One of examples:
I set yAxis.max
chart: {
type: "spline",
events: {
load: function() {
var chart = this,
max = chart.series[0].dataMax;
chart.update({
yAxis: {
max: max
}
});
}
}
},
I set tickAmount to 6 and used formatter function
yAxis: {
//categories: categories,
title: {
text: 'Position'
},
tickAmount: 6,
labels: {
formatter: function() {
var value = this.value + 1;
if (this.value < 9) {
return 'Pos 0' + value;
} else {
return 'Pos ' + value;
}
}
}
},
And I formatted tooltip:
tooltip: {
split: false,
useHTML: true,
style: {
pointerEvents: 'all'
},
formatter: function() {
var y = this.y + 1;
if (y < 10) {
return 'Pos 0' + y;
} else {
return 'Pos ' + y;
}
}
},
js Fiddle
I know that the last tick is not the last element of your category array, but it would be easier to "edit" your data and work on proper data than try to adapt ticks to your strange category array and data that doesn't fit categories.

Struggling to get this JSON data into highcharts

I have the following snippet of code which takes data from a JSON URL and inputs it into MariaDB.
Now I want to take that data back out the database (as the database records the JSON over time), and then put this into a graph, but I am having difficulty in getting the data out the JSON URL into highcharts... My data looks like this:
[{"time":"1509488314","hashrate":"34096322642","minersTotal":"99"},
{"time":"1509490093","hashrate":"34096645609","minersTotal":"101"},
{"time":"1509490201","hashrate":"34096374421","minersTotal":"101"},
{"time":"1509490321","hashrate":"34138925733","minersTotal":"101"},
{"time":"1509490441","hashrate":"34062086317","minersTotal":"101"},
{"time":"1509490561","hashrate":"34116887228","minersTotal":"101"},
{"time":"1509490681","hashrate":"34053449517","minersTotal":"103"},
{"time":"1509490801","hashrate":"34060600882","minersTotal":"103"},
{"time":"1509490921","hashrate":"34065888457","minersTotal":"103"},
{"time":"1509491041","hashrate":"34093378965","minersTotal":"105"}]
I wish to basically plot the time across the X axis, and hashrate as a line and minersTotal as a bar.
I have done the PHP / MariaDB bit, but doing this part is proving to be a struggle for me.
My php code:
$mysqli = new mysqli($servername, $username, $password, $dbname);
$myArray = array();
if ($result = $mysqli->query("SELECT * FROM hashrates LIMIT 100")) {
while($row = $result->fetch_object()) {
$myArray[] = $row;
}
echo json_encode($myArray);
}
$result->close();
$mysqli->close();

According this demo (Highcharts Demos › Dual axes, line and column). The data must be an array of values e.g: ["Item1", "Item2", "Item3"].
With your data, you can use Array#map().
var times = data.map(function(x) {
return new Date(x.time * 1000);
});
var hashrates = data.map(function(x) {
return x.hashrate * 1;
});
var minersTotals = data.map(function(x) {
return x.minersTotal * 1;
});
You can do something like this:
(function() {
var data = [{
"time": "1509488314",
"hashrate": "34096322642",
"minersTotal": "99"
},
{
"time": "1509490093",
"hashrate": "34096645609",
"minersTotal": "101"
},
{
"time": "1509490201",
"hashrate": "34096374421",
"minersTotal": "101"
},
{
"time": "1509490321",
"hashrate": "34138925733",
"minersTotal": "101"
},
{
"time": "1509490441",
"hashrate": "34062086317",
"minersTotal": "101"
},
{
"time": "1509490561",
"hashrate": "34116887228",
"minersTotal": "101"
},
{
"time": "1509490681",
"hashrate": "34053449517",
"minersTotal": "103"
},
{
"time": "1509490801",
"hashrate": "34060600882",
"minersTotal": "103"
},
{
"time": "1509490921",
"hashrate": "34065888457",
"minersTotal": "103"
},
{
"time": "1509491041",
"hashrate": "34093378965",
"minersTotal": "105"
}
];
var times = data.map(function(x) {
return new Date(x.time * 1000);
});
var hashrates = data.map(function(x) {
return x.hashrate * 1;
});
var minersTotals = data.map(function(x) {
return x.minersTotal * 1;
});

Let me know if this works for you.

I ended up going with this
$(function () {
var hashrates = new Array();
var minersTotal = new Array();
function refreshdata() {
$.getJSON("data.json", function(data) {
var hashrates = new Array();
var minersTotal = new Array();

var object = data[i];
var time = object.time * 1000;
hashrates.push([time, parseFloat(object.hashrate) / 1000000000]);
minersTotal.push([time, parseFloat(object.minersTotal)]);
}
$('#container').highcharts().series[0].setData(minersTotal, true);
$('#container').highcharts().series[1].setData(hashrates, true);
$('#container').highcharts().redraw();
});
}

Flot line chart with categories not working

I have a flot chart with the following code:
var options = {
lines: {
show: true
},
points: {
show: true
},
xaxis: {
tickSize: 1,
mode: "categories"
}
};
var data = [];
data.push(
{"label": "Agrobiodiversity for consumption",
"data": [["January", 3.0], ["February", 3.9], ["March", 2.0], ["April", 1.2], ["May", 1.3], ["June", 2.5],
["July", 2.0], ["August", 3.1], ["September", 2.9], ["October", 0.9],["November", 0.5],["December", 1.8]]});
$.plot($("#flot-dashboard-chart"), data, options);
But I I get:
I have tried addigng the categories in the axis options but nothing seem to work.
Any idea what else do I need to add or what do I need to correct?

U can use my high chart, and u can remove unnecessary stuffs.
