My json looks like this
var jStore = {
" identifier": "cpu",
"items": [
{
"Time": "02:52",
"Used": 100,
"Idle": 0
},
{
"Time": "02:57",
"Used": 100,
"Idle": 0
}....
]
};
I create a datastore and adding to the chart,
var realStore = new dojo.data.ItemFileReadStore({data: jStore});
var Ser = new dojox.charting.DataSeries(realStore, {query: {Idle: "*"} }, "Idle");
var Ser1 = new dojox.charting.DataSeries(realStore, {query: {Used: "*"} }, "Used");
chart.addAxis("x");
chart.addAxis("y", { vertical: true, fixLower: "major", fixUpper: "major" });
chart.addSeries("Used ",Ser);
chart.addSeries("Idle",Ser1);
the chart is rendering properly but the xaxis values are taken default (1,2,3..).
But i need to give the axis value as the Time in my json.
Xaxis should be like 02:52,02:54,02:56
Also in the tool tip it showing only the value i have given the series. But i would like to add the value+ xaxis value. Say for example 100 at 02:54.
Could someone help me on this.
You can specify custom labels for each value as follows:
mychart.addAxis("x", {fixLower: "minor", fixUpper: "minor", natural: false,
font: "normal normal 10pt Arial",
labels: [{value: 1, text: "Q2 FY11"},
{value: 2, text: "Q3 FY11"},
{value: 3, text: "Q4 FY11"},
{value: 4, text: "Q1 FY12"}]
});
You can also specify custom tooltip text as follows:
mychart.addSeries("Series A", [{ y: 2.3, tooltip: "FFFF"}, { y: 3.5, tooltip: "GGGG"}]);
In your case since you are using a store, the JSON that feeds the store needs to have a "tooltip" attribute for each value - dojo will use that to populate the tooltip

I'm creating a chart using Echarts and it looks like this on my page:
This causes me two issues, the first is that it's really bad to see the data in the graph, so I need to make the bars bigger.
The second issue is that the bar labels (on the left) are being cut.
My chart config is similar to this, it only has more data in it:
option = {
xAxis: {
},
yAxis: {
data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
},
series: [{
name: "Sale",
type: "bar",
data: [5, 20, 36, 10, 10, 20, 4]
}]
}
the solution was simple.
After messing around with both the echarts docs and the Laravel Charts that I was using, i managed to get what I wanted by setting a height property at my chart config.
Something like this:
option = {
xAxis: {
},
yAxis: {
data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
},
series: [{
name: "Sale",
type: "bar",
data: [5, 20, 36, 10, 10, 20, 4]
}],
height: 2000px
}
I'm trying to get the row ID of a select editor in Tabulator.
I have a few hundred rows of values, some i want to have a value of yes, some of no. When I change the value I then need to know which row it is for.
Here is my table.
adtable = new Tabulator("#adtable", {
ajaxURL: "getinfo.php",
layout: "fitColumns",
pagination:"local",
placeholder: "No Data Set available",
paginationSize: 40,
paginationSizeSelector: [100, 200, 500, 1000],
columns: [{
title: "Key Name",
field: "keyname",
formatter: "textarea",
sorter: "string",
headerFilter: "input"
},
{
title: "Active",
field: "display",
editor: "select",
editorParams: {
values: ["Yes", "No"],
sortValuesList: "asc",
defaultValue: "Yes",
elementAttributes: {
maxlength: "10",
},
},
],
});
});
Where can I put a command which will give me the row number.?
I need to update a db record. basiclaly, set display = either yes or no.
My preference was a tickCross but couldnt work that out either.
Any assistance is greatly appreciated.
using Tabulator 4.9
After a bit more thinking... it was actually blindingly simple.
{
title: "Active",
field: "display",
editor: "select",
editorParams: {
values: ["Yes", "No"], //create list of values from all values contained in this column
sortValuesList: "asc", //if creating a list of values from values:true then choose how it should be sorted
defaultValue: "Yes", //set the value that should be selected by default if the cells value is undefined
elementAttributes: {
maxlength: "10", //set the maximum character length of the input element to 10 characters
},
},
cellEdited: function(row) {
let thisrow = row.getData()
alert(thisrow.id + "is now " + thisrow.display)
}
},
Added here to help others who might be banging their head against a wall. I was obviously thinking of something more complicated.
echarts: bar chart bars are located left and right of the value on the category axis:
How to tell echarts to start the bar with the value on the category axis? Like this:
To clarify the problem, here ist another example. This is a chart of the hourly sum of precipitation. Every bar should show the sum from the bottom to the top of the hour, the data values are conencted to every bottom of the hour.
as you can see, the bars are not starting at 8:00, they are starting at 7:30.
Data: (timestamps are shown in CET)
series: [
{
name: "Niederschlag",
type: "bar",
data: [[1608534000000, 3], [1608537600000, 5], [1608541200000, 2], [1608544800000, 0], [1608548400000, 1] ],
barWidth: '100%'
}
]
It should look like this:
Start point of bar here doesn't matter, you need align labels to left: https://echarts.apache.org/en/option.html#series-bar.label.align
you need a hidden xAxis like below:
option = {
xAxis: [{
type: 'category',
data: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23],
show: false
}, {
type: 'category',
data: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24],
boundaryGap: false,
axisTick: { alignWithLabel: true },
position: 'bottom'
}],
yAxis: {
type: 'value'
},
series: [{
data: [120, 200, 150, 80, 70, 110, 130,120,210,110,210],
type: 'bar',
barCategoryGap:'20%',
itemStyle: {
},
xAxisIndex: 0,
backgroundStyle: {
color: 'rgba(220, 220, 220, 0.8)'
}
}]
};
You have not provided the complete chart config, so I recommend using this one. Also pay attention on method useUTC and you need to know that "By default, echarts uses local timezone to formate time labels"
So I see this state of Chart by you data with offset -180:
var myChart = echarts.init(document.getElementById('chart'));
var chartData = [
[1608534000000, 3],
[1608537600000, 5],
[1608541200000, 2],
[1608544800000, 0],
[1608548400000, 1],
];
var option = {
tooltip: {},
xAxis: {
type: 'time',
data: ['00:00', '01:00', '02:00', '03:00', '04:00', '05:00', '06:00', '07:00', '08:00', '09:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00', '20:00', '21:00', '22:00', '23:00'],
splitNumber: 24,
},
yAxis: {
type: 'value'
},
series: [{
name: "Niederschlag",
type: "bar",
data: chartData,
barWidth: '100%',
}],
useUTC: false,
};
myChart.setOption(option);
<script src="https://cdn.jsdelivr.net/npm/echarts#4.9.0/dist/echarts.min.js"></script>
<div id="chart" style="width: 1024px;height:400px;"></div>
I have a kendo's scatterline chart on my HTML page.
I have generated it as following.
objchart = $("#chart").kendoChart({
dataSource: {
data: Chartdata
},
background: mainbackground,
series: [{
type: "scatterLine",
xField: "date"
}],
xAxis: {
title: {
text: "Date"
},
min: min_date,
max: max_date,
name: "Date",
template: "#= kendo.toString(value,'MM/dd/yyyy HH:mm:ss')#",
type: "date",
baseUnit: "seconds",
background: xaxisbackcolor,
},
yAxis: {
title: {
text: "Closing stock prices"
},
min: min_close,
max: max_symbol,
background: yaxisbackcolor,
},
title: {
text: "Close and Volume Date-wise"
},
transitions: false,
zoom: setRange,
dragStart: onDragStart,
drag: onDrag,
dragEnd: onDragEnd
}).data("kendoChart");
Following is my datasource (calling from web api)
[{"date":"9/14/2015 1:20:00 AM","close":6.0,"volume":18.0,"open":58.0,"high":42.0,"low":60.0,"symbol":79.0}]
Now, I need to change the type of the chart from scatter line chart into others like series and bar chart.
when I change it as objchart.options.series[0].type = "column", it does not give any output.
It only leaves the blank chart behind.
What is the correct method to change or cast the chart from any type to any other type?
Thank you
I am trying to implement a SAPUI5 chart. I tried using the example in the Demo kit and now want to change it to use my data. I can get the chart to display but have a couple of issues.
1) I am having trouble with the 'name' of the dimensions and measures. From what I have had to do to get the chart to show, it seems as though the name has to match the field name in the 'value'. So for instance, if I have the field 'classProducts' I have this: value: {classProducts}' but of course that isn't much of a descriptive title. When I have had the name: 'XXX' if XXX is anything other than 'classProducts', I get this error:
"Failed to create chart:[50014] - Feed classProducts could not accept
more data containers."
From what I have found in documentation, the name is what you want to display in the legend and in the chart. Does anyone have any suggestions as to how to change the name shown to be any text I want?
2) I am using a Column chart and would like to compare a value between two years. I can get both years to display but is there a way to show each column in a different color? For instance, the value for 2013 is yellow and 2014 is blue?
3) Is there any known constraints on the height and width of a chart (minimum sizes)? I would like to make the chart real small, since I have to display a few at a time on the screen. I tried changing the width and height from the Demo Kit's values, but when I changed the values, the chart didn't show at all.
Here is my controller:
var oVizFrame = myView.byId("idVizFrameColumn");
var oPopOver = myView.byId("idPopOver");
var oModel = new JSONModel("ByYear_sum.json");
var oDataset = new FlattenedDataset({
dimensions: [{
name: "Year",
value: "{Year}"
}],
measures: [{
name: 'classProducts',
value: '{classProducts}'
}],
data: {
path: "/book"
}
});
oVizFrame.setDataset(oDataset);
oVizFrame.setModel(oModel);
oVizFrame.setVizProperties({
valueAxis: {
label: {
formatString: 'u'
}
},
legend: {
title: {
visible: false
}
},
title: {
visible: true,
text: 'Classified Products'
}
});
var feedValueAxis = new FeedItem({
'uid': "valueAxis",
'type': "Measure",
'values': ["classProducts"]
}),
feedCategoryAxis = new FeedItem({
'uid': "categoryAxis",
'type': "Dimension",
'values': ["Year"]
});
oVizFrame.addFeed(feedValueAxis);
oVizFrame.addFeed(feedCategoryAxis);
oPopOver.connect(oVizFrame.getVizUid());
Here is my sample data (it is a subset of the original data from the Demo Kit but with my field inserted):
{
"book": [{
"Year": 2001,
"Profit": 213863.42,
"Unit Price": 3001.79,
"Units Available": 35255,
"Cost": 512189.07,
"Revenue": 726052.49,
"classProducts": 904.00,
"Units Sold": 12548
}, {
"Year": 2002,
"Profit": 224016.45,
"Unit Price": 2475.09,
"Units Available": 40748,
"Cost": 428884.52,
"Revenue": 652900.98,
"classProducts": 791.00,
"Units Sold": 12607
}]
}
As mentioned, I resolved the issue to question #1. The others have been resolved as I went in a different direction.
