how to display between dates amcharts using angularjs - javascript

In my requirement I need to display the details means the doc start date and expiry date like that. I am using am charts, but I am unable to display between dates details.
Below is my code:
var chart = AmCharts.makeChart("chartdiv", {
"theme": "none",
"type": "serial",
"startDuration": 2,
"dataProvider": [{
"country": "20-10-05,
"visits": "15-03-03",

"color": "#FF6600"
}],
"valueAxes": [{
"position": "left",
"axisAlpha": 0,
"gridAlpha": 0
}],
"graphs": [{
"balloonText": "[[category]]: <b>[[value]]</b>",
"colorField": "color",

AmCharts Serial Chart: Center-align label under the axis points

In this AmCharts serial chart (Line chart), when the line chart gets rendered, the label in the category axis gets right-aligned from the datapoint intersection.
I need these labels to be center-aligned just below the datapoint intersection scale.
This is the current source code:
chart = AmCharts.makeChart(id, {
"type": "serial",
"autoMarginOffset": 20,
"usePrefixes":true,
"prefixesOfBigNumbers":[
{"number":1e+3,"prefix":"k"},
{"number":1e+6,"prefix":"M"},
{"number":1e+9,"prefix":"G"},
{"number":1e+12,"prefix":"T"},
{"number":1e+15,"prefix":"P"},
{"number":1e+18,"prefix":"E"},
{"number":1e+21,"prefix":"Z"},
{"number":1e+24,"prefix":"Y"}
],
"valueAxes": [{
"id": "v1",
"position": "left",
"ignoreAxisWidth":false
}],
"balloon": {
"borderThickness": 1,
"shadowAlpha": 0,
},
"graphs": [{
"id": "g1",
"fillColors":color,
"lineColor": color,
"bullet": "round",
"bulletBorderAlpha": 1,
"bulletColor": "#FFFFFF",
"fillColors": color,
"bulletSize": 5,
"hideBulletsCount": 50,
"lineThickness": 2,
"title": "red line",
"useLineColorForBulletBorder": true,
"valueField": "column-2"
}],
"chartCursor": {
"valueLineEnabled": true,
"valueLineBalloonEnabled": true,
"cursorAlpha": 0,
"valueLineAlpha": 0.5,
"categoryBalloonDateFormat": 'JJ-NN'
},
"categoryField": "column-1",
"categoryAxis": {
"gridPosition": "start",
"parseDates": true,
"dashLength": 1,
"minorGridEnabled": false,
"minPeriod": "mm",
"gridPosition":'middle',
"centerLabels":true,
"equalSpacing":false
},
"dataProvider": dataValue,
"export": {
"enabled": true
},
"allLabels": [{
"text": timeperiod,
"align": "center",
"y":0
}]
});
And this is the rendered graph:
How can this be fixed?

To get the label centered directly under the tick when parsing dates, you have to set equalSpacing to true.
var color = "#112233";
var timeperiod = "test";
var dataValue = generateData();
var chart = AmCharts.makeChart("chartdiv", {
"type": "serial",
"autoMarginOffset": 20,
"usePrefixes":true,
"prefixesOfBigNumbers":[
{"number":1e+3,"prefix":"k"},
{"number":1e+6,"prefix":"M"},
{"number":1e+9,"prefix":"G"},
{"number":1e+12,"prefix":"T"},
{"number":1e+15,"prefix":"P"},
{"number":1e+18,"prefix":"E"},
{"number":1e+21,"prefix":"Z"},
{"number":1e+24,"prefix":"Y"}
],
"valueAxes": [{
"id": "v1",
"position": "left",
"ignoreAxisWidth":false
}],
"balloon": {
"borderThickness": 1,
"shadowAlpha": 0,
},
"graphs": [{
"id": "g1",
"fillColors":color,
"lineColor": color,
"bullet": "round",
"bulletBorderAlpha": 1,
"bulletColor": "#FFFFFF",
"fillColors": color,
"bulletSize": 5,
"hideBulletsCount": 50,
"lineThickness": 2,
"title": "red line",
"useLineColorForBulletBorder": true,
"valueField": "column-2"
}],
"chartCursor": {
"valueLineEnabled": true,
"valueLineBalloonEnabled": true,
"cursorAlpha": 0,
"valueLineAlpha": 0.5,
"categoryBalloonDateFormat": 'JJ-NN'
},
"categoryField": "column-1",
"categoryAxis": {
//"gridPosition": "start", does not work with parseDates
"parseDates": true,
"dashLength": 1,
"minorGridEnabled": false,
"minPeriod": "mm",
"gridPosition":'middle',
//"centerLabelOnFullPeriod":false, //alternate solution but won't center directly under the axis tick
"equalSpacing":true
},
"dataProvider": dataValue,
"export": {
"enabled": true
},
"allLabels": [{
"text": timeperiod,
"align": "center",
"y":0
}]
});
function generateData() {
var data = [];
var firstDate = new Date();
firstDate.setHours(0,0,0,0);
for (var i = 0; i < 10; ++i) {
var newDate = new Date(firstDate);
newDate.setMinutes(i);
data.push({
"column-1": newDate,
"column-2": Math.floor(Math.random() * 20 + 1)
});
}
return data;
}
<script type="text/javascript" src="//www.amcharts.com/lib/3/amcharts.js"></script>
<script type="text/javascript" src="//www.amcharts.com/lib/3/serial.js"></script>
<div id="chartdiv" style="width: 100%; height: 300px;"></div>
You can also use centerLabelOnFullPeriod if you don't want to use equalSpacing, but it will only position it slightly to the right of the tick but not quite at the center.

initialImage not displayed on top of trendLine in Amcharts

I'm trying to put a image to the beginning of a trend line using the initialImage property of the trendline. But it doesn't come up to the beginning of the trend line.
Here is the code:
"trendLines": [ {
"initialDate": "2017-10-26 18:52:13",
"initialValue": 0,
"lineColor": "#CC0000",
"initialImage": {
"svgPath": "M6.84,25.682L24.316,15.5L6.684,5.318V25.682z",
"color": "#050",
"width": 13,
"height": 13,
"rotation": 90,
"offsetX": 4,
"offsetY": -17,
"balloonText": "2017-10-26 11:52:43"
},
"finalDate": "2017-10-26 18:52:13",
"finalValue": 80
}],
Here is the DEMO.

initialImage is placed at the location defined by initialValue and initialDate, so it actually is being placed at the beginning. In your case, the beginning is at the bottom due to your initial values with respect to the final values. If you want it to appear on top of that particular trendline, set it as the finalImage instead.

Amchart change dateformat of label

I'm using AmChart do display my chart with the information from my server.
If you run the code and scroll down and hover the chart it will display (Aug 01, 2012 OR Sep 01, 2012 OR Oct 01, 2012)
I'cant seem to find a way to change the value so it only display the month (Aug OR Sep OR Oct)
Does anyome know how to fix that?

You can modify the format string in the chartCursor's categoryBalloonDateFormat property to "MMM" instead of the default "MMM DD, YYYY".
"chartCursor": {
"categoryBalloonDateFormat": "MMM",
// ...
}

var height = $('#chartdiv').height() / 2;

How to disable the labels of x-axis amcharts

I am trying not to show the labels of x-axis, which in this case are:
"7.5, 8.0, 8.5, 9.0" and so on.
This is what I have tried so far:
<div id="chartdiv"></div>
var chart = AmCharts.makeChart("chartdiv", {
"theme": "light",
"type": "serial",
"dataProvider": [{
"name": "3s",
"startTime": 8,
"endTime": 11,
"color": "#FF0F00"
}],
"valueAxes": [{
"axisAlpha": 0,
"gridAlpha": 0.1
}],
"startDuration": 1,
"graphs": [{
"balloonText": "<b>[[category]]</b><br>starts at [[startTime]]<br>ends at [[endTime]]",
"colorField": "color",
"fillAlphas": 0.8,
"lineAlpha": 0,
"openField": "startTime",
"type": "column",
"valueField": "endTime"
}],
"rotate": true,
"columnWidth": 1,
"categoryField": "name",
});
JSFiddle Demo

Use labelsEnabled on your value axis:
"valueAxes": [{
"axisAlpha": 0,
"gridAlpha": 0.1,
"labelsEnabled": false
}],
Here's the updated fiddle.

labelsEnabled can be used in categoryAxis as well:
"categoryAxis": {
"axisColor": "#555555",
"gridAlpha": 0.1,
"gridColor": "#FFFFFF",
"gridCount": 50,
"labelsEnabled": false
},

Use integersOnly on your valueAxis property:
"valueAxes":[{
"integersOnly": true
}],
Now your value will be displayed like 7, 8, 9...
