HighChart Drilldown axis automatically show the differences instead of actual label - javascript

http://jsfiddle.net/sohxow92/
The y-axis after clicking on drilldown automatically show the short label, try 1-2h, and take a look at y-axis you will see, starting from 68, it shows 8, 12 and so on.
What config of highchart do I need to modify to make this show the original label?
Following is part of the drilldown object.
"drilldown": {
"xAxis": {
"type": "category",
"labels": {
"overflow": "justify"
}
},
"yAxis": {
"labels": {
"overflow": "justify"
},
"title": {
"text": "Visits"
}
},
"activeDataLabelStyle": {
"textDecoration": "none"
},
"activeAxisLabelStyle": {
"textDecoration": "none"
},
}
Thanks in advance.

How do you create a partial pie chart on vega-lite for single data point?

I am using vega-lite to create a pie chart (on Airtable). I have a single data point, which is a target set by me, and the percentage complete for that target. For example, as below:
{
"Target": "Get 10 customers",
"Percentage complete": "60"
}
I would like to make a pie chart that is 60% complete, and the rest empty. Similar to the interactive single arc pie chart displayed https://vega.github.io/vega-lite/docs/arc.html.
My code currently looks like this
{
"$schema": "https://vega.github.io/schema/vega-lite/v4.json",
"title": "Customer Acquired",
"width": "container",
"height": "container",
"data": {
"values": [
{
"Target": "Get 10 customers",
"Percentage complete": "60"
}
]},
"mark": {
"type": "arc",
"tooltip": true
},
"encoding": {
"theta": {
"field": "Percentage complete",
"type": "quantitative"
}
}
}
And my pie chart currently just looks like this:
I realise I could force the pie chart to appear the way I want it by manually setting the theta2 property like so
"mark": {
"type": "arc",
"tooltip": true,
"theta2": 3.5
}
However I don't know what the "Percentage complete" field will be and this value may change often, so I would rather not have to do it manually. Is this at all possible with vega-lite?
The domain for the theta encoding will automatically be set to the minimum and maximum of your input data. To show the correct portion of the chart, you need to set the domain to [0, 100]:
"encoding": {
"theta": {
"field": "Percentage complete",
"type": "quantitative",
"scale": {"domain": [0, 100]}
}
}
You can view the resulting chart in the vega editor:

Angular Highcharts
When i place these config with JQuery Its works fi
jQuery Highcharts
Is this is the highcharts-ng issue ?
When I checked your fiddle I had observed that you have not included the heatmap.js library.
Also, You need to move your chart and colorAxis inside the options block.
Check the below working fiddle link in which you can see the square blocks identical to your jQuery example.

amcharts gantt axis reverting to time instead of date

I'm trying to build a Gantt chart based on amcharts. I will probably have only one item per line though, so I tried with the sample _JSON_ganttDateBased but when I leave only one item per row (John, Smith and Ben only have one task each), the X axis reverts to time instead of date.
I looked into floating bar as a possible way around but I'm not sure I can put dates on the axis.
Thanks
This happens because the total time span is small and there's plenty of space to put grid lines / labels on X axis. So the chart reverts to lines.
This can be easily resolved by enforcing the granularity for your value axis to daily:
"valueAxis": {
"type": "date",
"minPeriod": "DD"
}
That should revert your axis increments back to days.
Here's a working example:
var chart = AmCharts.makeChart( "chartdiv", {
"type": "gantt",
"period": "DD",
"valueAxis": {
"type": "date",
"minPeriod": "DD"
},
"brightnessStep": 10,
"graph": {
"fillAlphas": 1,
"balloonText": "[[open]] - [[value]]"
},
"rotate": true,
"categoryField": "category",
"segmentsField": "segments",
"dataDateFormat": "YYYY-MM-DD",
"startDateField": "start",
"endDateField": "end",
"dataProvider": [ {
"category": "John",
"segments": [ {
"start": "2015-01-02",
"end": "2015-01-03"
} ]
}, {
"category": "Smith",
"segments": [ {
"start": "2015-01-01",
"end": "2015-01-02"
} ]
}, {
"category": "Ben",
"segments": [ {
"start": "2015-01-06",
"end": "2015-01-09"
} ]
} ],
"chartCursor": {
"valueBalloonsEnabled": false,
"cursorAlpha": 0,
"valueLineBalloonEnabled": true,
"valueLineEnabled": true
},
"chartScrollbar": {
}
} );

<script src="http://www.amcharts.com/lib/3/serial.js"></script>

amcharts: reverse time (category) axis?

Is it possible to reverse the category axis of a time-based chart in amcharts? I know that the value axis can be easily flipped but I've not seen a solution for the category axis. I need to have the most relevant and therefore recent data on the left.
I'm using a time-based area chart. Here's a demo: http://jsfiddle.net/N5rpu/1/
In the example I've reversed the value axis and done the same to the category axis just to show that nothing happens.
var chart = AmCharts.makeChart("chartdiv", {
"type": "serial",
"theme": "none",
"pathToImages": "http://www.amcharts.com/lib/3/images/",
"dataProvider": chartData,
"valueAxes": [{
"position": "left",
"title": "Unique visitors",
"reversed": true
}],
"graphs": [{
"fillAlphas": 0.4,
"valueField": "visits"
}],
"chartScrollbar": {},
"chartCursor": {
"categoryBalloonDateFormat": "JJ:NN, DD MMMM",
"cursorPosition": "mouse"
},
"categoryField": "date",
"categoryAxis": {
"minPeriod": "mm",
"parseDates": true,
"reversed": true
}
});
In fact I had the opposite problem - dates in the AmCharts categoryAxis where being displayed in reverse from chronological order!
This was achieved by ordering the dates from most recent to less recent in the dataProvider array, i.e.
"dataProvider": [{
"value": 74,
"date": "2014-11-16"
},
{
"value": 73,
"date": "2014-11-15"
},
{
"value": 70,
"date": "2014-11-14"
}];

Highcharts separate categories

Check this fiddle to get an idea of what I am talking about
This is my xAxis configuration:
"xAxis": {
"categories": ["Category ONE", "Category TWO"],
"allowDecimals": false,
"title": {
"text": " ",
"align": "middle",
"style": {
"color": "steelblue"
}
},
"labels": {
"y": 12,
"style": {
"color": "steelblue"
}
}
},
I need category one and category two to be separated by a few pixels (50,100, whatever amount I want) but cannot find the solution for this issue. I know there is a way to do it for series but there is no equivalent for when you only want to separate the categories.
Thanks in advance
plotOptions have some options which can control series. Padding is possible to get by changing value of groupPadding:
"plotOptions": {
"column": {
"groupPadding": 0.1
}
}
