Google Charts One Control - google-visualization

How can i make one control with multiple Charts but different data?
My code so far:
var overallDurationComparionLineChart = new google.visualization.ChartWrapper({
chartType: 'LineChart',
containerId: 'overallDurationChartDiv',
dataTable: overallDurationComparionLineChartData,
});
var enqueuedDurationComparionLineChart = new google.visualization.ChartWrapper({
chartType: 'LineChart',
containerId: 'enqueuedDurationChartDiv',
dataTable: enqueuedDurationComparionLineChartData,
});
var control = new google.visualization.ControlWrapper({
controlType: 'ChartRangeFilter',
containerId: 'control_div',
options: {
filterColumnIndex: 0,
ui: {'labelStacking': 'vertical', chartType: 'LineChart', snapToData: false},
}
});
var dashboard = new google.visualization.Dashboard(document.getElementById('dashboard_div'));
dashboard.bind(control, [overallDurationComparionLineChart, enqueuedDurationComparionLineChart]);
dashboard.draw();
I know dashboard.draw(); requires a DataTable (or DataView).
And if call it without any parameters there is no error but the the dashboard and its content isn't called either.
So how can i make it work?

Count number of rows after filter in Google Visualisation Table

I have implement various controls in a Google Visualisation Table for multiple filter: CategoryFilter, StringFilter and NumberRangeFilter like this exemple
http://jsfiddle.net/asgallant/Ena84/
Is it possible know the number of rows visualised in table after every filter settings?
Thank you.
function drawTable() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Name');
data.addColumn('string', 'Team');
data.addColumn('string', 'Nationality');
data.addColumn('number', 'Height');
data.addColumn('number', 'Weight');
data.addColumn('number', 'OverallRating');
data.addColumn('string', 'Foot');
data.addRows([
['MESSI','FC BARCELONA','ARGENTINA',169,67,25,'Left foot'],
['A. INIESTA','FC BARCELONA','SPAIN',170,65,28,'Right foot'],
['XAVI','FC BARCELONA','SPAIN',170,68,32,'Right foot']
]);
var dashboard = new google.visualization.Dashboard(document.getElementById('dashboard'));
var stringFilter = new google.visualization.ControlWrapper({
controlType: 'StringFilter',
containerId: 'string_filter_div',
options: {
filterColumnIndex: 0
}
});
var numberRangeFilter = new google.visualization.ControlWrapper({
controlType: 'NumberRangeFilter',
containerId: 'numnber_range_filter_div',
options: {
filterColumnIndex: 5,
minValue: 0,
maxValue: 100,
ui: {
label: 'Overall Rating'
}
}
});
var table = new google.visualization.ChartWrapper({
chartType: 'Table',
containerId: 'table_div',
options: {
showRowNumber: true
}
});
dashboard.bind([stringFilter, numberRangeFilter], [table]);
dashboard.draw(data);
}
google.load('visualization', '1', {packages:['controls'], callback: drawTable});

once the 'ready' event fires on any of the controls, charts, or dashboard
you can use the getDataTable method on any of the controls or charts
to getNumberOfRows
see following working snippet...
function drawTable() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Name');
data.addColumn('string', 'Team');
data.addColumn('string', 'Nationality');
data.addColumn('number', 'Height');
data.addColumn('number', 'Weight');
data.addColumn('number', 'OverallRating');
data.addColumn('string', 'Foot');
data.addRows([
['MESSI','FC BARCELONA','ARGENTINA',169,67,25,'Left foot'],
['A. INIESTA','FC BARCELONA','SPAIN',170,65,28,'Right foot'],
['XAVI','FC BARCELONA','SPAIN',170,68,32,'Right foot']
]);
var dashboard = new google.visualization.Dashboard(document.getElementById('dashboard'));
var stringFilter = new google.visualization.ControlWrapper({
controlType: 'StringFilter',
containerId: 'string_filter_div',
options: {
filterColumnIndex: 0
}
});
var numberRangeFilter = new google.visualization.ControlWrapper({
controlType: 'NumberRangeFilter',
containerId: 'numnber_range_filter_div',
options: {
filterColumnIndex: 5,
minValue: 0,
maxValue: 100,
ui: {
label: 'Overall Rating'
}
}
});
var table = new google.visualization.ChartWrapper({
chartType: 'Table',
containerId: 'table_div',
options: {
showRowNumber: true
}
});
dashboard.bind([stringFilter, numberRangeFilter], [table]);
google.visualization.events.addListener(dashboard, 'ready', function () {
// get number of rows
console.log(table.getDataTable().getNumberOfRows());
});
dashboard.draw(data);
}
google.load('visualization', '1', {packages:['controls'], callback: drawTable});

Column data label on google bar chart

I am trying to add a column data label to a google bar chart.
I have followed the instructions given in the API docs, and this is what I get:
google.charts.load('current', {'packages':['bar']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Searches'],
['1998', 9800],
['2000', 60000000],
['2007', 1200000000],
['2008', 1745000000],
['2009', 2610000000],
['2010', 3627000000],
['2011', 4717000000],
['2012', 5134000000],
['2013', 5922000000],
['2014', 5740000000]
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1,
{ calc: "stringify",
sourceColumn: 1,
type: "string",
role: "annotation" }]);
var options = {
chart: {
title: 'Google searches',
subtitle: 'Average searches per day 1998-2014',
}
};
var chart = new google.charts.Bar(document.getElementById('columnchart_material'));
chart.draw(view, options);
}
I must be doing something wrong as the chart fails to render any data labels.
What am I doing wrong?
https://jsfiddle.net/q9edfpte/1/

I did a number of changes*, and this one ultimately worked.
*Changes:
- 'packages':['bar'] --> 'packages':['corechart']
- google.charts.Bar --> google.visualization.ColumnChart
Working version (though needs beautifying):
google.charts.load("current", {packages:['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Searches'],
['1998', 9800],
['2000', 60000000],
['2007', 1200000000],
['2008', 1745000000],
['2009', 2610000000],
['2010', 3627000000],
['2011', 4717000000],
['2012', 5134000000],
['2013', 5922000000],
['2014', 5740000000]
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1,
{ calc: "stringify",
sourceColumn: 1,
type: "string",
role: "annotation" }]);
var options = {
title: 'Google searches',
subtitle: 'Average searches per day 1998-2014',
};
var chart = new google.visualization.ColumnChart(document.getElementById('columnchart_values'));
chart.draw(view, options);
}

How to apply placeholder to Google Visualization control wrapper string filter input?

I have to apply placeholder to Google Visualization control wrapper string filter input.I tried with
var stringFilter = new google.visualization.ControlWrapper({
'controlType': 'StringFilter',
'containerId': 'search_container',
'options': {
'filterColumnLabel': 'Name',
'matchType':'any',
'ui': {'label': ''}
}
});
google.visualization.events.addListener(stringFilter, 'ready', function(){
$(".google-visualization-controls-stringfilter").prop('placeholder', "Search..");
});
but it does not work.

You need to select the <input> that is inside the div with the class .google-visualization-controls-stringfilter:
google.visualization.events.addListener(stringFilter, 'ready', function () {
$('.google-visualization-controls-stringfilter input').prop('placeholder', 'Search...');
});

How to change ControlWrapper Category filter ui.caption text color based on the caption?

How to change ControlWrapper Category filter ui.caption text color based on the caption? I tried like following code,but it not works.
var category_Picker = new google.visualization.ControlWrapper({
'controlType': 'CategoryFilter',
'view': {'columns': [1,2,3,4,7,8]},
'containerId': 'category_filter_container',
'options': {
'filterColumnLabel': 'P/A',
'ui': {
'matchType':'any',
'label': '',
'caption':'All',
'labelStacking': 'horizontal',
'allowTyping': false,
'allowMultiple': false,
'cssClass':'category_Picker_Class'
}
},
'state':{'selectedValues':['A']}
});
var table = new google.visualization.ChartWrapper({
'chartType': 'Table',
'containerId': 'summary_details_table',
'options': {'allowHtml': true,'alternatingRowStyle':true,'width':'100%','height':'600px'}
});
// Create the dashboard.
var data_DashBoard = new google.visualization.Dashboard(document.getElementById('summary_details_table')).bind(category_Picker, table).draw(view);
$(".category_Picker_Class").css({"color":"red"});

Try wrapping the jQuery inside a "ready" event handler for the control, as the control probably doesn't exist at the time you try to set the CSS:
google.visualization.events.addListener(category_Picker, 'ready', function () {
$(".category_Picker_Class .charts-menu-button-caption").css({"color":"red"});
});
Place the event handler in between creating the CategoryPicker and drawing the Dashboard. jsfiddle example

Combining two types of Category Filter in Google Charts API

I wanted to enable users to filter the results being displayed on the chart. Google API provides CategoryFilter which enforces filtering by rows. Here is my code which works perfectly fine
<html>
<head>
<!--Load the Ajax API-->

// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
function drawChart() {
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(<?=$jsonTable?>);
var countryPicker = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'negeri',
dataTable: data,
options: {
filterColumnLabel: 'Negeri',
ui: {
labelStacking: 'vertical',
allowTyping: false,
allowMultiple: true
}
},
// Define an initial state, i.e. a set of metrics to be initially selected.
state: {'selectedValues': ['Kedah', 'Johor']}
});
var chart = new google.visualization.ChartWrapper({
chartType: 'ColumnChart',
containerId: 'chart_div',
options: {
title: 'Statistik Negeri vs. Kategori Sukan',
width: 1000,
height: 1000,
hAxis: {title: 'Negeri', titleTextStyle: {color: 'blue'}},
vAxis: {title: 'Jumlah Kategori', titleTextStyle: {color: 'blue'}}
}
});
// Create the dashboard.
new google.visualization.Dashboard(document.getElementById('dashboard')).
// Configure the controls so that:
// - the 'Country' selection drives the 'Region' one,
// - the 'Region' selection drives the 'City' one,
// - and finally the 'City' output drives the chart
bind(countryPicker, chart).
// Draw the dashboard
draw(data);
}
</script>
</head>
<body>
<div id="dashboard">
<div id="negeri"></div>
<div id="chart_div"></div>
</div>
</body>
</html>
However in my datatable, I would also want to filter by columns. These two types of filtering should work together. (dependent; by bind() function). I have referred to #asgallant http://jsfiddle.net/asgallant/WaUu2/ and that is the feature that I wanted to combine with.
How can I possibly combine them? I have tried combining setChartView() by #asgallant with google's dashboard() but it's not working.

You want to bind your countryPicker filter to the chart as normal, but do not bind the columnFilter control to anything - the setChartView function handles everything for the columnFilter. You need to tweak a couple other lines to make it work with a dashboard, but nothing major. This is what it should look like:
function drawChart() {
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(<?=$jsonTable?>);
var columnsTable = new google.visualization.DataTable();
columnsTable.addColumn('number', 'colIndex');
columnsTable.addColumn('string', 'colLabel');
var initState= {selectedValues: []};
// put the columns into this data table (skip column 0)
for (var i = 1; i < data.getNumberOfColumns(); i++) {
columnsTable.addRow([i, data.getColumnLabel(i)]);
// you can comment out this next line if you want to have a default selection other than the whole list
initState.selectedValues.push(data.getColumnLabel(i));
}
var countryPicker = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'negeri',
dataTable: data,
options: {
filterColumnLabel: 'Negeri',
ui: {
labelStacking: 'vertical',
allowTyping: false,
allowMultiple: true
}
},
// Define an initial state, i.e. a set of metrics to be initially selected.
state: {'selectedValues': ['Kedah', 'Johor']}
});
var columnFilter = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'colFilter_div',
dataTable: columnsTable,
options: {
filterColumnLabel: 'colLabel',
ui: {
label: 'Kategori Sukan',
allowTyping: false,
allowMultiple: true,
allowNone: false,
selectedValuesLayout: 'belowStacked'
}
},
state: initState
});
var chart = new google.visualization.ChartWrapper({
chartType: 'ColumnChart',
containerId: 'chart_div',
options: {
title: 'Statistik Negeri vs. Kategori Sukan',
width: 1000,
height: 1000,
hAxis: {title: 'Negeri', titleTextStyle: {color: 'blue'}},
vAxis: {title: 'Jumlah Kategori', titleTextStyle: {color: 'blue'}}
}
});
// Create the dashboard.
var dashboard = new google.visualization.Dashboard(document.getElementById('dashboard')).
bind(countryPicker, chart);
function setChartView () {
var state = columnFilter.getState();
var row;
var view = {
columns: [0]
};
for (var i = 0; i < state.selectedValues.length; i++) {
row = columnsTable.getFilteredRows([{column: 1, value: state.selectedValues[i]}])[0];
view.columns.push(columnsTable.getValue(row, 0));
}
// sort the indices into their original order
view.columns.sort(function (a, b) {
return (a - b);
});
chart.setView(view);
chart.draw();
}
google.visualization.events.addListener(columnFilter, 'statechange', setChartView);
var runOnce = google.visualization.events.addListener(dashboard, 'ready', function () {
google.visualization.events.removeListener(runOnce);
setChartView();
});
columnFilter.draw();
dashboard.draw(data);
}
google.load('visualization', '1', {packages:['corechart'], callback: drawChart});
