Google Charts (GeoChart) - Europe region doesn't display correctly

I'm struggling to find out why geochart map cuts top of the map when using the Europe region.
For example Finland does not show up completely.
Has anyone ever encountered such problem?
Code
$(document).ready(function() {
google.charts.load('visualization', '1', {'packages': ['geochart']});
google.charts.setOnLoadCallback(drawVisualization);
function drawVisualization() {
var data = google.visualization.arrayToDataTable([
['Country', 'ColorIndex'],
['fi', 2],
['ee', 1],
['gb', 2],
['at', 2],
['dk', 2],
['es', 2]
]);
var opts = {
region: '150',
displayMode: 'regions',
resolution: 'countries',
width: 480,
height: 320,
enableRegionInteractivity: true,
backgroundColor: 'transparent',
datalessRegionColor: 'transparent',
legend: 'none',
tooltip : { trigger : 'none' },
colorAxis: {
values: [1, 2, 3],
colors: ['#050b55', '#003399', '#eb5f0f']
}
};
var container = document.getElementById('visualization');
var geochart = new google.visualization.GeoChart(container);
geochart.draw(data, opts);
}
});

Gap on right and left sides in areaChart

I am using Google Charts to visualize some data. When drawing full width chart in bordered container I can see small gaps on the left and right side. Is it possible to remove it? The chart area width is set to 100%.
JS:
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales'],
['2013', 1000],
['2014', 1170],
['2015', 660],
['2016', 1030]
]);
var options = {
hAxis: {
textPosition: 'none',
gridlines: {
color: 'transparent'
}
},
vAxis: {
textPosition: 'none',
gridlines: {
color: 'transparent'
}
},
legend: { position: 'none' },
chartArea: {
'width': '100%',
'height': '100%',
'backgroundColor': '#fff'
},
colors: ['#ddd'],
height: 50,
lineWidth: 0,
areaOpacity: 1,
annotations: {
stemColor : 'none'
},
tooltip : {
trigger: 'none'
}
};
var chart = new google.visualization.AreaChart(document.getElementById('chart'));
chart.draw(data, options);
}

Changing colour of Google Pie Charts next page indicator

In a Google Pie chart, I want to change the colour of the indicator in the legend to go to the next results. This is now blue, and I can't seem to change that, although I can change the colour of the pie slices (done) or even of the text (not necessary). Here is a screenshot: Google pie chart.
Here is the code:
var options1 = {
legend: 'none',
pieSliceText: 'label',
width: '85%',
height: '85%',
chartArea: {'width': '80%', 'height': '80%'},
legend: {'position': 'bottom'},
backgroundColor: {fill:'transparent'},
pieSliceBorderColor: 'transparent',
colors: ['#41ac89', '#2b9b38', '#b3b300', '#D9C022', '#bab673']
};

you can use the following options...
text: legend.pagingTextStyle
arrows: legend.scrollArrows
e.g.
legend: {
position: 'bottom',
// style paging text and arrows
pagingTextStyle: {
color: '#616161'
},
scrollArrows:{
activeColor: '#616161',
inactiveColor:'#e0e0e0'
}
},
see following working snippet...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['', 'Views'],
['dat', 40],
['nom', 10],
['gen', 10],
['hid1', 2],
['hid2', 3]
]);
var options = {
legend: 'none',
pieSliceText: 'label',
width: 200,
height: 200,
chartArea: {'width': '80%', 'height': '80%'},
legend: {
position: 'bottom',
// style paging text and arrows
pagingTextStyle: {
color: '#616161'
},
scrollArrows:{
activeColor: '#616161',
inactiveColor:'#e0e0e0'
}
},
backgroundColor: {fill: 'transparent'},
pieSliceBorderColor: 'transparent',
colors: ['#41ac89', '#2b9b38', '#b3b300', '#D9C022', '#bab673']
};
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
});

Google Chart access fill property of path

I am trying to access fill property of a series in a stacked area (Google charts). I want the bottom series of the stacked chart to become transparent as shown in the JSFiddle code.
Can one please assist in this please? Your help is very much appreciated.
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div class="row">
<!-- Div that will hold the pie chart-->
<div id="chart_div"></div>
</div>
google.charts.load('current', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
['2013', 1000, 400],
['2014', 1170, 460],
['2015', 660, 1120],
['2016', 1030, 540]
]);
var options = {
isStacked: true,
title: 'Company Performance',
hAxis: { title: 'Year', titleTextStyle: { color: '#333' } },
vAxis: { minValue: 0 },
series:
{
0: { id: 'ss223', type: 'area', backgroundColor: { fill: 'black' } },
1: { type: 'area', backgroundColor: { fill: 'transparent' }}
}
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
}

just replace...
backgroundColor: { fill: 'transparent' }
with...
color: 'transparent'
the series will be numbered, starting with zero on the bottom
see following working snippet...
note: if you want to make the area solid black, not just the border,
add this to your options...
areaOpacity: 1
google.charts.load('current', {
callback: function () {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses', 'Line 1', 'Line 2'],
['2013', 1000, 400, 200, 400],
['2014', 1170, 460, 200, 400],
['2015', 660, 1120, 200, 400],
['2016', 1030, 540, 200, 400]
]);
var options = {
isStacked: true,
title: 'Company Performance',
hAxis: { title: 'Year', titleTextStyle: { color: '#333' } },
vAxis: { minValue: 0 },
series:
{
0: { id: 'ss223', type: 'area', color: 'transparent' },
1: { type: 'area', color: 'black' },
2: { type: 'line', color: 'red' },
3: { type: 'line', color: 'blue' }
}
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
},
packages:['corechart']
});

Google Pie Chart does not display properly the slices

As you can see in the following image I have many pie charts in my webpage and they do not fill completely the container (generally only an half is filled or LESS):
Here some code:
var data1 = google.visualization.arrayToDataTable([
['Tipo', 'Valore'],
['Recapitate', sent],
['Ritornate/Bloccate', errors]
]);
options1 = {
width: 250,
height: 250,
pieHole: 0.5,
colors: ['#06dd00','#e12a00'],
legend: {position: 'none'},
pieSliceText: 'none',
tooltip: {textStyle: {color: '#333', fontName: 'Arial', fontSize: 16}},
chartArea:{left: 0,top: 0,width: "100%",height: "100%"},
enableInteractivity: false/*,
animation: { duration: 1000, easing: 'out' }*/
};
chart1 = new google.visualization.PieChart(document.getElementById('grafico-inviate'));
chart1.draw(data1, options1);
var data2 = google.visualization.arrayToDataTable([
['Tipo', 'Valore'],
['Aperte', unique_opened],
['Non aperte', combined1]
]);
options2 = {
width: 250,
height: 250,
pieHole: 0.5,
colors: ['#3e9ca8','#ff5932'],
legend: {position: 'none'},
pieSliceText: 'none',
tooltip: {textStyle: {color: '#333', fontName: 'Arial', fontSize: 16}},
chartArea:{left: 0,top: 0,width: "100%",height: "100%"},
enableInteractivity: false/*,
animation: { duration: 1000, easing: 'out' }*/
};
chart2 = new google.visualization.PieChart(document.getElementById('grafico-aperte'));
chart2.draw(data2, options2);
The problem arises independently from the OS/Web-Browser.
I do not know if this is a bug of the visualization API or am I missing something?
SOLVED!!:
Do not ask me why but if i put the data in the following way (using the javascript Number() function) it works:
var data2 = google.visualization.arrayToDataTable([
['Tipo', 'Valore'],
['Aperte', Number(unique_opened)],
['Non aperte', Number(combined1)]
]);

I do not know if this is your case but you can produce such semicircle in the following way. Your code little changed (only second part):
var unique_opened = 5.555; // real value: 11.11;
var combined1 = 44.445; // real value: 88.89;
var noshow = 50;
....
var data2 = google.visualization.arrayToDataTable([
['Tipo', 'Valore'],
['Aperte', unique_opened],
['Non aperte', combined1],
['noshow', noshow]
]);
options2 = {
width: 250,
height: 250,
pieHole: 0.5,
colors: ['#3e9ca8','#ff5932', '#ffffff'],
...
And you get:
