Drawing visual Lines in Google Charts - google-visualization

I'm writing a Google Chart. It has stacked columns. On top of that I want to draw 2 lines, which indicate min and max allowed value.
The only solution I came up with, was modifying the first example of ComboCharts. My result looks like this:
Which isn't sufficient. The graph is variable, so if there's only 1 Quartal shown, the line will solely be a dot. My Questions are:
Is there a way to draw the line further, so it hits the left and right boundary of the Graph?
Can I draw markup lines into the graph, without pretending it's another datapoint?
You can fiddle with a ComboChart here if you want.

You can't get the lines to go edge-to-edge with a discrete (string-based) x-axis. If you switch to a continuous (number, date, datetime, timeofday) axis, then you can add one row before your real data and one row after that contain the goal lines (and nulls for the other data series):
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'Quarter');
data.addColumn('number', 'Value 1');
data.addColumn('number', 'Value 2');
data.addColumn('number', 'Value 3');
data.addColumn('number', 'Goal 1');
data.addColumn('number', 'Goal 2');
data.addRows([
[0, null, null, null, 10, 14],
[1, 5, 4, 7, null, null],
[2, 6, 9, 6, null, null],
[3, 2, 6, 4, null, null],
[4, 3, 6, 4, null, null],
[5, null, null, null, 10, 14]
]);
var chart = new google.visualization.ComboChart(document.querySelector('#chart_div'));
chart.draw(data, {
height: 400,
width: 600,
isStacked: true,
legend: {
position: 'top'
},
seriesType: 'bars',
interpolateNulls: true,
series: {
3: {
type: 'line'
},
4: {
type: 'line'
}
},
hAxis: {
format: 'Q#',
ticks: [1, 2, 3, 4],
viewWindow: {
min: 0.5,
max: 4.5
}
},
chartArea: {
left: '10%',
width: '80%'
}
});
}
google.load('visualization', '1', {packages:['corechart'], callback: drawChart});
See working example: http://jsfiddle.net/asgallant/W67qU/
Here is some explanation of what is going on (edit on Nov 24, 2022 by Jorr.it):
At the top and bottom of the DataTable there are extra rows added with the goals only. With the hAxis.viewWindow option the two new goal dots are just cut off the chart, but resulting in a full line over the whole width of the chart. Finally option "interpolateNulls" needs to be set to connect the two invisible dots "over" the null values in the bar rows.

Maybe a bit late but I faced the same issue. I was trying to set max and min lines into a line chart with a lot of data points in the serie and I wanted to avoid adding new series with a lot of repeated points so I used overlays ( https://developers.google.com/chart/interactive/docs/overlays#javascript2 ).
Here are an example, It's just a draft in which I'm working now but maybe can help:

Google column charts X-axis label different from value

I'd like to create column chart with X axis numeric values 1, 2, 3, 4 ... N and Y value of course different on every column.
I can't find out how to change labels on X line under bars, to string. For example - 1 could be marked as Elephant, 2 as Horse etc.
I could use string as X values, but then there is no way to get zoom working. At least, I didn't find any way to get it working.
simple example with strings, I'd like to achieve same appearance as this one, but with numeric values on X axis.
google.charts.load('current', {packages: ['corechart', 'bar']});
google.charts.setOnLoadCallback(drawBasic);
function drawBasic() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'animal');
data.addColumn('number', 'count');
data.addRows([
['Elephant', 5],
['Horse', 2],
['Dog', 7],
['Cat', 4],
]);
var options = {
explorer: {
axis: 'horizontal',
keepInBounds: true,
},
title: 'Testing',
hAxis: {
title: 'Animal',
},
vAxis: {
title: 'number'
}
};
var chart = new google.visualization.ColumnChart(
document.getElementById('chart_div'));
chart.draw(data, options);
}
Chart should look like this, but with working zoom:
Chart example
to use string labels on a continuous axis,
you will need to provide your own ticks
using object notation, provide the value (v:) and formatted value (f:)
{v: 1, f: 'Elephant'}
see following working snippet...
google.charts.load('current', {
callback: drawBasic,
packages: ['corechart']
});
function drawBasic() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'animal');
data.addColumn('number', 'count');
data.addRows([
[1, 5],
[2, 2],
[3, 7],
[4, 4]
]);
var options = {
explorer: {
axis: 'horizontal'
},
title: 'Testing',
hAxis: {
ticks: [
{v: 1, f: 'Elephant'},
{v: 2, f: 'Horse'},
{v: 3, f: 'Dog'},
{v: 4, f: 'Cat'}
],
title: 'Animal',
},
vAxis: {
title: 'number'
}
};
var chart = new google.visualization.ColumnChart(
document.getElementById('chart_div')
);
chart.draw(data, options);

number of labels on the horizontal axis in Google Chartwrapper

In Google Charts, the 'hAxis': {'gridlines': {'count': 3} } statement seems to work, but when I'm using chartWrapper as part of an interactive plot, it does not. I don't really care about vertical gridlines, but I want to control how many labels are on the X axis. I think labels are usually attached to gridlines - one label per gridline.
I have an example from the Google Charts website, where the only thing I changed was to put try and put in 3 gridlines:
https://jsfiddle.net/emorris/gLcq1h2j/
chart option ticks is only supported by a continuous axis
in the fiddle you shared, the view placed on the chart,
converts the first column from type 'date' to 'string',
which results in a discrete axis
// Convert the first column from 'date' to 'string'.
'view': {
'columns': [{
'calc': function(dataTable, rowIndex) {
return dataTable.getFormattedValue(rowIndex, 0);
},
'type': 'string'
}, 1, 2, 3, 4]
}
to control how many labels are on the X axis, remove the view
to build the ticks dynamically here, use the state of the range filter,
to know the date range currently displayed on the chart
the chart will need to be redrawn when the control's 'statechange' event fires
see following working snippet, an axis label is created for every 5 days...
google.charts.load('current', {
callback: drawChartRangeFilter,
packages: ['corechart', 'controls']
});
function drawChartRangeFilter() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');

change = change >= 0 ? change + 10 : change - 10;
open = close;
close = Math.max(50, open + change);
low = Math.min(open, close) - (Math.cos(day * 1.7) + 1) * 15;

Multiple Google charts on one web page

I've 2 google charts on one page and both are displayed correctly. The problem is when I set fontName of both charts to 'Open Sans', only one chart is displayed.

Google Line Charts, place circle on annotation

i am new to google charts i want to make a graph for cricket rate rate and wicket that should look something like this
i have searched google and found out that i might do it with the help of annotations and i have written this code:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawVisualization);
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'Overs');
data.addColumn('number', 'Run-rate');
data.addColumn({type: 'string', role:'annotation'});
data.addColumn({type: 'string', role:'annotationText'});
data.addRows([
[1, 6, null, null],
[2, 6, null, null],
[10, 2, null, null],
[20, 3.2, null, 'Shoaib Malik'],
[21, 3, '2', 'Shahid Afridi'],
[30, 4, null, null],
[40, 5, 'B', 'This is Point B'],
[50, 6, null, null],
]);
var options = {
title: 'Run Rate',
pointSize:0,
hAxis: {
gridlines: {
color: 'transparent'
}
},
};

draw(data, options);
}
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
</body>
</html>
and this is the output of the code:
now the problem is that i want to show circle like the first image instead of text 2,B
i cant do it using pointSize because i want circle where wicket falls, not where the over ends...
can any1 tell me how to do this ? either i can replace text with circle or any other way out
You can't replace the text if you want to use the annotation functionality (as the text is what is generated by the annotations). You could use an overlapping data series to show only certain points. Here's an example that shows an overlapping series (I removed the annotations for simplicity, but you can still use them if you want to):
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'Overs');
data.addColumn('number', 'Run-rate');
data.addColumn('boolean', 'Wicket falls');
data.addRows([
[1, 6, false],
[2, 6, false],
[10, 2, true],
[20, 3.2, false],
[21, 3, true],
[30, 4, true],
[40, 5, false],
[50, 6, false]
]);
// create a DataView that duplicates points on the "Run Rate" series where "Wicket falls" is true
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
type: 'number',
label: data.getColumnLabel(2),
calc: function (dt, row) {
// return the value in column 1 when column 2 is true
return (dt.getValue(row, 2)) ? dt.getValue(row, 1) : null;
}
}]);
var options = {
title: 'Run Rate',
pointSize:0,
hAxis: {
gridlines: {
color: 'transparent'
}
},
series: {
0: {
// put any options pertaining to series 0 ("Run-rate") here
},
1: {
// put any options pertaining to series 1 ("Wicket Falls") here
pointSize: 6,
lineWidth: 0
}
}
};
new google.visualization.LineChart(document.getElementById('chart_div')).
// use the view instead of the DataTable to draw the chart
draw(view, options);
}
google.load('visualization', '1', {packages:['corechart'], callback: drawVisualization});

is it possible to give space between bars using Google ColumnChart

I am using the Following show the Column Chart for my records, i want to give spaces between the bars that are generating, please help.

};
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));

</html>
var options = {
bar: { groupWidth: '100%' },
The usual format for a column chart is that each series has its own column, grouped by rows. Since you have all 4 data points in the same row, you will end up having them all clumped together in the same group. If you change your data, you will get separation as each will be in a separate group:
var data = google.visualization.arrayToDataTable([
['Date', 'Data'],
['11-02-2013', 10],
['11-02-2013', 20],
['11-02-2013', 30],
['11-02-2013', 5]
]);
If you want to show multiple people, grouped by weeks, then you would do something like this:
var data = google.visualization.arrayToDataTable([
['Date', 'Alan', 'Beatrice', 'Charlie', 'Diana'],
['11-02-2013', 10, 5, 15, 20],
['11-02-2013', 20, 1, 2, 3],
['11-02-2013', 30, 25, 20, 15],
['11-02-2013', 5, 7, 9, 11]
]);
This will group your data by week (so all 4 people would be shown in the same week as a single group) with gaps between the weeks (between each 'group' of data).
