Remove column key from google chart - charts

I am using column google chart. I need to change the direction of column key which is highlighted into red circle in image below.
So what I want to achieve
Is there any property so I can change the direction like top, bottom or left side so it displayed properly (Revenue) as of now it display (R...).
If direction cannot be changed, then how can I remove this from charts

What you need is the property called chartArea
You can control how much area from top, right, bottom or left to be shown.
Here chart area is area of only the chart, excluding label, legend or any other value other than the chart itself. You can reduce the chart area so that label/legend can come completely.
chartArea: {
height: '500',
left: 0,
right: 0,
top: 30,
bottom: 0
},
Regarding the legend positioning, you can change place of legend using
legend: {
position: 'left'
}
To remove legends altogether use
legend:{position: 'none'}
See below snippet or this JSFIDDLE to see how it works.
google.charts.load('current', {
'packages': ['corechart']
});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Submitter', 'Count'],
['Service', 168],
['NAME 1', 42],
['NAME 2', 36],
['NAME 3', 35],
['NAME 4', 34],
['NAME 5', 30],
['NAME 6', 24],
['NAME 7', 21],
['NAME 8', 18]
]);
var options = {
pieSliceText: 'percentage',
legend: {
position: 'none'
},
height: '500',
chartArea: {
height: '500',
left: 0,
right: 0,
top: 30,
bottom: 0
},
};
var chart = new google.visualization.PieChart(document.getElementById('chart6_div'));
chart.draw(data, options);
}

Google Visualization SteppedAreaChart with time as axis incorrectly aligned

I'm creating a SteppedArea chart in Google Visualization to display queue length at various times of the day. My problem is that the steps in the chart don't align with the associated times. They are always one data point out. In the example below, my dataTable has 9:00 = 0, 12:00 = 3 and 14:00 = 6, but the resultant chart offsets the values, so it appears the queue between 9 and 12 is 3 when it really should be 0.
Is this a bug in the Chart rendering or am misunderstanding something ?
I guess my workaround is to offset my initial dataTable.
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('timeofday', 'Time of Day');
data.addColumn('number', 'Queue Length');
// DataTable of Time and Queue length
data.addRows([
[[9,0,0], 0],
[[12,0,0], 3],
[[14,0,0], 6],
]);
var options = {
width: 500,
height: 500,
legend: {position: 'top'},
enableInteractivity: false,
chartArea: {
width: '85%'
},
hAxis: {
viewWindow: {
min: [8,0,0],
max: [15,0,0]
},
gridlines: {
count: -1,
units: {hours: {format: ['h a']}}
},
minorGridlines: {count: 0},
}
};
var chart = new google.visualization.SteppedAreaChart(
document.getElementById('chart_div'));
chart.draw(data, options);
}
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

I've shifted the data via a view which seems to give me the right looking chart. See the example which shows before and after. Note I had to add a dummy point at the end of the dataset otherwise the last point gets missed off. I also had to assume the first point would be zero which is acceptable in my case. Unless another idea surfaces I'll go with this.
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('timeofday', 'Time of Day');
data.addColumn('number', 'Queue Length');
data.addRows([
[[9,0,0], 2],
[[11,30,0], 1],
[[12,0,0], 2],
[[13,0,0], 3],
[[14,0,0], 2],
]);
var options = {
width: 500,
height: 500,
legend: {position: 'top'},
enableInteractivity: false,
chartArea: {
width: '85%'
},
hAxis: {
viewWindow: {
min: [8,0,0],
max: [15,0,0]
},
gridlines: {
count: -1,
units: {hours: {format: ['h a']}}
},
minorGridlines: {count: 0},
}
};
var chart = new google.visualization.SteppedAreaChart(
document.getElementById('chart_div'));
chart.draw(data, options);
// need to add dummy point to end.
data.addRows([
[[23,59,0], 0]
]);
// use a view to shift the data so that it returns the value from previous row.
var data2 = new google.visualization.DataView(data);
data2.setColumns([0,
{calc: function (dt, row) {
if (row === 0) {return 0}
else {return dt.getValue(row-1,1)}
},
label: 'Queue Moved',type: 'number'}
]);
var chart2 = new google.visualization.SteppedAreaChart(
document.getElementById('chart2_div'));
chart2.draw(data2, options);
}

Replace a showR2 with a custom text in a Google Chart?

I am playing around with Google Chart to look a certain way. In this situation I have a combo chart a line and column chart.
I have stumble upon a view "layout" problems
How do replace the show2r legend with just some custom text? At
the moment says: y = 2.032E-4 * x - 8.203 r^2 = 7.005E-3 and I want
to replace it with "Trendline (Lineair)
2/ Also the legend gets a
1/2 and Arrows left and right. I like the legend to always be
visible?
3/ The x axis doesn't display all dates, how can I set that
as a default?
4/ How do I add vertical line in say month June??
Regards
to change the trendline label in the legend, use option --> labelInLegend
there are no standard options to change the value in the tooltip,
but it can be changed manually using event --> onmouseover
when the legend's position is top,
you can use option --> legend.maxLines
to increase the number of lines available and prevent the arrows...
to ensure all dates are shown on the x-axis,
allow enough room by using option --> chartArea.bottom
see following working snippet for examples of each...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['x', 'y0', 'y1'],
[new Date(2017, 11, 28), 175, 10],
[new Date(2017, 11, 29), 159, 20],
[new Date(2017, 11, 30), 126, 35],
[new Date(2017, 11, 31), 129, 40],
[new Date(2018, 0, 1), 108, 60],
[new Date(2018, 0, 2), 92, 70]
]);
var options = {
chartArea: {
bottom: 72
},
hAxis: {
slantedText: true
},
height: 400,
legend: {
maxLines: 2,
position: 'top'
},
tooltip: {
isHtml: true
},
trendlines: {
0: {
labelInLegend: '0-Linear Trend',
showR2: true,

visibleInLegend: true
},
1: {
labelInLegend: '1-Linear Trend',
showR2: true,
type: 'linear',
visibleInLegend: true
}
},
width: 400
};
var container = document.getElementById('chart_div');
var chart = new google.visualization.ColumnChart(container);
google.visualization.events.addListener(chart, 'onmouseover', function (props) {
var tooltipLabels = container.getElementsByTagName('span');
for (var i = 0; i < tooltipLabels.length; i++) {
if (tooltipLabels[i].innerHTML.indexOf('y =') > -1) {
tooltipLabels[i].innerHTML = 'CUSTOM TEXT:';
}
}
});
chart.draw(data, options);

Google Gauge Chart - Add Text Label for each gauge section

I am trying to use Google gauge charts in my page. Now I want to add text in the chart for each section or colors. Can I do that inside the chart. I tried doing some html modification but with no help.
Trying from this link -https://developers.google.com/chart/interactive/docs/gallery/gauge
So for example, I would like to add text1 for white color and so on.
use the majorTicks config option to provide labels for the major ticks
see following working snippet...
google.charts.load('current', {
callback: function () {
var container = document.getElementById('chart_div');
var chart = new google.visualization.Gauge(container);
var data = google.visualization.arrayToDataTable([
['Label', 'Value'],
['Memory', 80],
['CPU', 55],
['Network', 68]
]);
var options = {
width: 600, height: 200,
redFrom: 90, redTo: 100,
yellowFrom:75, yellowTo: 90,
majorTicks: ['A', 'B', 'C', 'D', 'E'],
minorTicks: 3
};
chart.draw(data, options);
},
packages: ['gauge']
});

Google Charts line chart not showing 0-100 as a percentage scale

I'm trying to create a basic Google Charts line chart to show percentages for 3 values over time. The chart is displaying but I'm struggling to get the vAxis to show 0 - 100%, the top value is just the highest value from my dataset (45%).
This is the code I'm using:
<html>
<head>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':['line']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'date');
data.addColumn('number', 'tool1');
data.addColumn('number', 'tool2');
data.addColumn('number', 'tool3');
data.addRows([
[new Date(2000, 8, 5), 10, 20, 30],
[new Date(2001, 8, 5), 20, 30, 40],
[new Date(2002, 8, 5), 25, 35, 45],
]);
var options = {
chart: {
title: 'Tool rollout'
},
vAxis: {minValue: 0,
maxValue: 100,
format: "percent"
},
width: 900,
height: 500,
};
var chart = new google.charts.Line(document.getElementById('line'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="line"></div>
</body>
</html>
But this is how it's rendering:
The docs suggest that setting vAxis.maxValue "Moves the max value of the vertical axis to the specified value; this will be upward in most charts. Ignored if this is set to a value smaller than the maximum y-value of the data." but I'm obviously missing something as this doesn't seem to get used.
You´re using material chart Google api, try using:
vAxis: {
format: "#.#%",
viewWindow: {
max:1.0,
min:0.2
}
}

can't hide the tooltip (equation) on the trendline on a google chart

can you please help me hide the tooltip (equation) on the trendline on the google chart on this page ?
Thanks
Here are the chart options I am using :
var options = {
title: 'Weight of pro surfer vs. Volume of his pro model',
hAxis: {title: 'Weight (kg)', minValue: 53, maxValue: 100}, //55
vAxis: {title: 'Volume (l)'}, //, minValue: 20, maxValue: 40}, //20
legend: 'none',
colors: ['#000000'],
series: {
1: { color: '#06b4c8' },
2: { color: '#575e6a' }
},
legend: {position: 'top right', textStyle: {fontSize: 8}},
chartArea: {width: '60%'},
//tooltip:{trigger:'none'}, //it hides all tooltips on the whole graph
trendlines: { 0: {//type: 'exponential',
visibleInLegend: true,
color: 'grey',
lineWidth: 2,
opacity: 0.2,
tooltip:{trigger:'none'}, //does nothing
labelInLegend: 'Linear trendline\n(Performance)'
}
} // Draw a trendline for data series 0.
};
If I add tooltip:{trigger:'none'}, before trendlines it hides the tooltips of the whole graph.
It has been implemented but not documented yet:
trendlines: {0: {tooltip: false}}
Only solution I was able to make is replacing the text of the tooltips from trendline. This example makes use of jquery, so if you are able to use jquery you can use:
google.visualization.events.addListener(chart, 'onmouseover', function(e){
$('svg *:contains("* x")').each(function(){
$(this).text('')
})
})
If not, it should be possible to replicate with pure js, but that´s the main idea: find the tooltips that have the formula attached, and replace the text with nothing
Here is a working example: http://jsfiddle.net/juvian/aapdjbpt/
