Is it possible to display the label of each bar outside the upper bound of a bar chart using react-apexcharts?

I am editing a bar chart that should display the values ​​above each bar. I need the values ​​to be displayed outside the upper limit of the chart. I managed to get this graph:
chart i have
However, I need the values ​​to be displayed as if it were a double x-axis (my understanding is that apexchart only has double-axis implemented for the y-axis). In a nutshell, I need this:
chart i need
I managed to move the labels to the top using "offsety" inside "datalabels" in my chart options, but they stay inside the chart, sitting right on the line of the maximum value of the y-axis (and I need them to be located above this line ).
These are my chart options:
const options = {
grid: {
position: 'front'
},
legend:{
position: "bottom",
horizontalAlign: "right",
offsetY: 10
},
colors:["#59ad30","#134E32","#3A7B05","#59AD31"],
chart: {
toolbar:{show:false},
type: 'bar',
height: 350
},
plotOptions: {
bar: {
dataLabels: {
position: 'top',
},
columnWidth: `${categorias.length*13}%`,
},
},
dataLabels: {
enabled: true,
formatter: function (val, opts) {
return `${val.toFixed(1)} Lt`
},
offsetY: -1000,
style: {
fontSize: '11px',
fontFamily: 'Roboto, Helvetica, Arial, sans-serif',
fontWeight: undefined,
colors: ["#000000"]
},
},
stroke: {
show: true,
width: 2,
colors: ['transparent']
},
xaxis: {
categories: categorias,
labels:{
style: {
fontWeight: "bold",
},
}
},
yaxis: {
labels: {
formatter: function(val) {
return `${Math.floor(val)} Lt`
}
}
},
fill: {
opacity: 1
},
tooltip: {
y: {
formatter: function (val) {
return `${val} lts`
}
}
}
};

Highcharts scatter external data

I created document with highcharts scatter graph
Highcharts.chart('container', {
chart: {
type: 'scatter',
zoomType: 'xy'
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
title: {
enabled: true,
text: 'Date of entry'
},
startOnTick: true,
endOnTick: true,
showLastLabel: true
},
yAxis: {
title: {
text: 'Values'
}
},
legend: {
layout: 'vertical',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF',
borderWidth: 1
},
plotOptions: {
scatter: {
marker: {
radius: 5,
states: {
hover: {
enabled: true,
lineColor: 'rgb(100,100,100)'
}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: 'Dana {point.x} = {point.y}'
}
}
},
series: [{
name: 'Values',
color: 'rgba(223, 83, 83, .5)',
data: [[167.6, 64.5], [167.6, 72.3], [167.6, 61.4]]
}]
});
and this works. This code is from documentation page. I get normal scatter data like on this page Highcharts scatter jsfiddle
Now, I created another PHP file that produces me with data I actually need. it is in document highcharts.php and result is this
[07.03.2017,21000],[07.03.2017,25000],[07.03.2017,33000],[07.03.2017,27000],[07.03.2017,30000],[01.01.2017,700],[11.05.2017,0],[11.05.2017,0],[11.05.2017,0],[11.05.2017,0],
how to connect data to this highcharts.php file? I found some examples but I cannot get it to work. So for start I need this, ONE line of data to show on scatter diagram. I lost few days and just do not get it what I am doing wrong.

If your PHP file returns the array presented above, you need to parse it a little bit in order to use it as data array in a scatter series. First of all, dates should be strings. Secondly, you need to use new Date() to create Date instance and use getTime() to return timestamps. Also, change xAxis type to datetime.

HighCharts - Horizontal line with the zoomed average of the values

I need to display the average of the values of my 2 datasets, but with a specific characteristic: when the users zoom the chart, the average line is recalculated ONLY with the values of the zoomed area.
How is this done?
Here is my JS:
$(function () {
$('#container').highcharts({

xAxis: {
type: 'datetime',
title: {
enabled: true,
text: 'Date'
},
startOnTick: true,
endOnTick: true,
showLastLabel: true
},
yAxis: {
title: {
text: ''
}
},
legend: {
layout: 'vertical',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF',
borderWidth: 1
},
plotOptions: {
scatter: {

}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x} date, {point.y} dose'
}
}
},
series: [{

});
});
Thanks in advance!

This can be done several ways. I am going to show you the way to do it via chart.events.redraw. Whenever you do a zoom (or reset zoom) the chart is redrawn and this gives us a good hook into calculating and adding items to chart at that time. Here is the code block for the redraw event:
Here is a live demo.
I made it verbose so you can see each step. We are going to use getExtremes() to find out what are max and min xAxis and yAxis indexes are. From this we determine if the points in each series are within this "window". If they are not within the window we ignore. If they are then we add the y-value to a var and increment the point counter by 1. Once we are done we do a simple check to make sure we are not going to divide by zero and then calculate the average.
Once we have the average we then will draw a plotLine at the value of the average we calculated above. First we see if a plotline exists with our id. If it does we remove it. Then we create our new plotline.
There is some clean up to do as well (such as, do you include a 0-value plotline based on your business rules) but this should get you started.
Attempted to add code block in edit as original answer attempt would not let it through. Still unable to post code block.

Highcharts PieChart Legend paging faulty

Creating a few pie charts using Highcharts which render fine, however the legend does not swap between pages. It updates the page number (E.g. 1/4 -> 2/4 -> 3/4) but the contents of the legend does not change.
I have used code from http://jsfiddle.net/qegmnsm7/ and simply passed my own data into it; giving this code:
var areaOptions = {
chart: {
renderTo: 'areaPie',
defaultSeriesType: 'pie',
width: 900,
height: 600
},
title: {
text: "Test Pie Chart."
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
y: 30,
navigation: {
activeColor: '#3E576F',
animation: true,
arrowSize: 12,
inactiveColor: '#CCC',
style: {
fontWeight: 'bold',
color: '#333',
fontSize: '12px'
}
}
},
exporting: {
buttons: {
printButton: {
enabled: false
}
}
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
color: '#000000',
connectorColor: '#000000',
formatter: function () {
return Math.round(this.percentage) + '% (' + this.y + ')';
}
},
showInLegend: true
, point: {
events: {
legendItemClick: function () {
filterList(this);
this.select();
return false;
},
click: function () { filterList(this); }
}
}
},
series: [{
type: 'pie',
name: 'Banana',
data: []
}]
}
};
areaOptions.series = #Html.Raw(ViewBag.Area);
var areaChart = new Highcharts.Chart(areaOptions);
areaChart.render();
Giving this:
However upon clicking the 'down' arrow, the legend stays exactly the same - apart from 1/2 changes to 2/2.
I have used the example code linked above in my application and it works perfectly; therefore I expected simply updating the data input to work. However something is messing it up and I can't find any other users' questions or google links to help.
What am I doing wrong that stops the legend from paging properly?
Edit: Here is a JSFiddle showing exactly what I mean.

areaChart.render(); is not a part of official API and is causing the problem with legend paging. Removing this part of code will fix you issue.

Justify stack labels

I am having problems with my stack labels. I have them rotated -90 degrees and I have set align to left and vertical align to bottom. But for some reason the label is aligned to the bottom of each column but not as I expected it to do. The center of the text label is align to the bottom, not the first letter of the label. Is there a way to accomplish what I want without manually calculating the y offset for each individual stack label? And if not, how would I best do that tiresome calculation?
See attached fiddle:
$(function () {
$('#container').highcharts({
chart: { type: 'column' },
title: { text: '' },
xAxis: { categories: [""] },
yAxis: [{
title: { text: '', style: { color: '#4572A7'} },
labels: {
formatter: function () { return Highcharts.numberFormat(this.value, 0) + " USD" },
style: { color: '#4572A7' }
},
stackLabels: {
enabled: true,
style: { fontSize: '1.5em', fontWeight: 'bold', color: 'black' },
formatter: function () { return this.stack; },
rotation: -90, x: -5,
verticalAlign: 'bottom',
align: 'left'
}}],
legend: { borderWidth: 1, shadow: false },
plotOptions: {
column: { stacking: 'normal' },
series: { shadow: false}
},
series: [{ data: [34, 34, 54, 12, 23], stack: 'Stack 1' }]
});
});

Cheers!
EDIT
This is a simplified version of what I actually have. In my real chart I have dynamic content so there are different texts in the stack labels and the columns have various heights. None of this I know beforehand and thus I need to, somehow, dynamically adjust the stack labels to the bottom (and to the left of) of the columns regardless of the length of the text in the actual label.
Thanks again!

You can change:
verticalAlign: 'middle'
Example: http://jsfiddle.net/Zprjn/7/
or if you want at bottom, add:
y: -40
Example: http://jsfiddle.net/Zprjn/8/

I just figured it out! I had to specify
textAlign: 'left'
as well and that fixed it!
