Google Chart API Control range and snapToData issues

Google Chart API Control range and snapToData issues - javascript

Using google charts API with line chart controlled by range finder.I am stuck with two annoying issues:
The control has extra space before and after the data values it was set to follow, leaving an ugly space the control can slide to.
I can not seem to get the control to snap to data value.
If you can give me a pointer what I am doing wrong I will appreciate it a lot.
I set a JSfiddle here: http://jsfiddle.net/Db4fm/2/
Thank you very much!

HTML

The space before and after your data values is a result of setting your range filter's chart's domain axis to axis 0, which is a "string" type axis. If you want the line to go edge-to-edge, the domain axis has to be a continuous data type ("number", "date", "datetime", "timeofday"). If you change the control's chart's view.columns parameter to [1, 2], the spaces will go away:
var control1 = new google.visualization.ControlWrapper({
controlType: 'ChartRangeFilter',
containerId: 'control_activity',
options: {
filterColumnIndex: 1,
ui: {
chartType: 'LineChart',
snapToData: true, // this bugger is not working
chartOptions: {
width: 950,
height: 50,
chartArea: {
left: 40,
top: 0,
width: 700,
height: 50
},
hAxis: {
textPosition: 'none'
}
},
chartView: {
columns: [1, 2]
},
minRangeSize: 1
}
},
state: {
range: {
start: 7,
end: 8
}
}
});
I couldn't replicate your problem with the ui.snapToData option.
Updated jsfiddle with fix: http://jsfiddle.net/asgallant/Db4fm/3/

Change line 67 to as follows:
'columns': [1, 2]

How to create custom bar chart using google charts?

I want to create bar chart using google charts
Condition to create chart is like Bar should have fixed width and padding between the bars and it should be plot at center of grid lines.
I used google chart for this .
google.charts.load("current", {packages:['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
["Element", "Density", { role: "style" } ],
["Copper", 8.94, "#b87333"],
["Silver", 10.49, "silver"],
["Gold", 19.30, "gold"],
["Platinum", 21.45, "color: #e5e4e2"]
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1,
{ calc: getValueAt.bind(undefined, 1),
sourceColumn: 1,
type: "string",
role: "annotation" },
2]);
var options = {
title: "Density of Precious Metals, in g/cm^3",
width: 600,
height: 400,
bar: {
groupWidth: 20
},
legend: { position: "none" },
};
var chart = new google.visualization.ColumnChart(document.getElementById("columnchart_values"));
chart.draw(view, options);
}
function getValueAt(column, dataTable, row) {
return dataTable.getFormattedValue(row, column);
}
JsFiddle for the same
I want to create something like this.

in order to get the bars between the gridlines,
will need to use a continuous data type for the x-axis,
timeofday will work, which takes an array of either 3 or 4 numbers,
representing hours, minutes, seconds, and optionally milliseconds, respectively
['Time', 'Value'],
[[9, 30, 0], 20],
[[10, 30, 0], 30],
...
set the data values at the half minute mark,
then use ticks at the full minute mark...
ticks: [
[9, 0, 0],
[10, 0, 0],
...
for padding between the bars, use a percentage...
bar: {
groupWidth: '95%'
},
see following working snippet...
google.charts.load('current', {
packages:['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['Time', 'Value'],
[[9, 30, 0], 20],
[[10, 30, 0], 30],
[[11, 30, 0], 57],
[[12, 30, 0], 70],
[[13, 30, 0], 80],
[[14, 30, 0], 55],
[[15, 30, 0], 45],
[[16, 30, 0], 20],
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
calc: function (dt, row) {
return dt.getFormattedValue(row, 1);
},
role: 'annotation',
type: 'string'
}]);
var options = {
annotations: {
alwaysOutside: true,
stem: {
color: '#cb4335',
length: 20,
},
},
bar: {
groupWidth: '95%'
},
colors: ['#cb4335'],
hAxis: {
format: 'ha',
gridlines: {
color: 'transparent'
},
ticks: [
[9, 0, 0],
[10, 0, 0],
[11, 0, 0],
[12, 0, 0],
[13, 0, 0],
[14, 0, 0],
[15, 0, 0],
[16, 0, 0],
],
},
height: 400,
legend: {position: 'none'},
tooltip: {trigger: 'none'},
vAxis: {
textStyle: {
color: 'transparent'
}
},
};
var chart = new google.visualization.ColumnChart(document.getElementById('columnchart_values'));
chart.draw(view, options);
});
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="columnchart_values"></div>
EDIT
to expand the gridlines, use option hAxis.viewWindow.min & max
and chartArea.width can extend the chart to the edges of the chart container
see following working snippet...
google.charts.load('current', {
packages:['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['Time', 'Value'],
[[9, 30, 0], 20],
[[10, 30, 0], 30],
[[11, 30, 0], 57],
[[12, 30, 0], 70],
[[13, 30, 0], 80],
[[14, 30, 0], 55],
[[15, 30, 0], 45],
[[16, 30, 0], 20],
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
calc: function (dt, row) {

Google Charts Dashboard - "View" property on ChartWrapper not working

I'm trying to create a Google Charts dashboard with multiple charts all based on the same dataset. Different charts require different columns of the data, though, and every time I try to limit the columns in the ChartWrapper view, I get an error. Here's my code:
google.charts.load('current', {packages: ['corechart', 'bar', 'controls']});
google.charts.setOnLoadCallback(drawDashboard);
function drawDashboard() {
var data = google.visualization.arrayToDataTable([
['Institution', 'Ineligible', 'Active', 'Closed With Outcome', 'Closed Outside Process', 'Closed Without Outcome',
'Eligibile'],
['CAC', 144, 35, 38, 4, 175, 115 ],
['SPF', 62, 2, 12, 1, 93, 4 ],
['CM', 69, 18, 10, 7, 64, 32 ],
['IP', 36, 4, 28, 24, 38, 62 ],
['EVM', 77, 7, 8, 2, 78, 19 ],
['RMC', 63, 5, 9, 1, 62, 18 ],
['MRI', 17, 5, 1, 5, 8, 3 ],
['IRM', 8, 0, 2, 1, 10, 5 ],
]);
var dashboard = new google.visualization.Dashboard(
document.getElementById('dashboard_div'));
var iamFilter = new google.visualization.ControlWrapper({
'controlType': 'CategoryFilter',
'containerId': 'iam_filter',
'options': {
'filterColumnLabel': 'IAM',
'ui': {
'caption': "Choose mechanisms",
'label': '',
'labelStacking': 'vertical',
'selectedValuesLayout': 'belowWrapping',
'cssClass': 'ChartControl',
}
},
});
var columnChart = new google.visualization.ChartWrapper({
'chartType': 'ColumnChart',
'containerId': 'id_outcomes',
'options': {
colors: ['#1b5869', '#42bb9a', '#bec3c7', '#9953b5', '#4c96da'],
animation: {
"startup": true,
duration: 1000,
easing: 'out',
},
legend: { position: 'right'},
bar: { groupWidth: '75%' },
isStacked: true,
},
'view': {'columns': [0,2,3]},
});
dashboard.bind(iamFilter, columnChart);
dashboard.draw(data);
}
In the above example, the error I get is:
Invalid column index 3. Should be an integer in the range [0-2].
But if I change it to 'view': {'columns': [0,2]}, the error I get is:
Invalid column index 2. Should be an integer in the range [0-1].
The view property works fine on the ControlWrapper, but I need it to work on the ChartWrapper, since a single ControlWrapper needs to filter data for multiple charts.
Any advice is much appreciated!

Java script Google Chart division of the xas show unwanted distribution

Hello i am plotting a Column Chart using Javascript and Google Chart. which shows per week the tickets wich met the critea of the SLA. So what i expect on the x-as are whole week numbers but instead i get divided numbers (see figure below). What can i do to change that ?
To create the column chart i use the following dataset:
[[1, 7, 4, 5, 0, 0, 1]
,[2, 12, 2, 9, 1, 1, 0]
,[3, 10, 0, 1, 1, 1, 0]
,[4, 4, 3, 0, 1, 0, 0]
,[5, 7, 5, 0, 0, 0, 0]
,[6, 6, 1, 0, 0, 0, 0]
,[7, 11, 4, 0, 0, 0, 0]
,[8, 11, 2, 0, 0, 0, 1]]
To plot this data to a chart i use the following code:
console.info('Start ticketsSolvedPerWeek SLA')
console.info(ds.Data)
// (A)Define column headers
var dataNew = new google.visualization.DataTable()
dataNew.addColumn('number', 'Weeknumber');
dataNew.addColumn('number', '00');
dataNew.addColumn('number', '01');
dataNew.addColumn('number', '02');
dataNew.addColumn('number', '03');
dataNew.addColumn('number', '04');
dataNew.addColumn('number', '05');
dataNew.addRows(ds.Data)
//(3) Set graph options
var options = {
title: ds.title,
hAxis: {
title: 'Weeknumber'
},
vAxis: {
title: 'Tickets'
},
trendlines: {
0: {
type: 'polynomial',
degree: 3,
visibleInLegend: true,
pointSize: 20, // Set the size of the trendline dots.
opacity: 0.1
}
},
width: 750,
height: 500,
};
//(4) Draw Graph
var slaChart = new google.visualization.ColumnChart(
document.getElementById('ticketsSLA'));
slaChart.draw(dataNew, options);

you can use option hAxis.ticks to provide custom axis labels
the option takes an array of values the same type as the data table axis column
in the following working snippet,
data table method getDistinctValues(columnIndex) is used to create the array for ticks
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var dataNew = new google.visualization.DataTable()
dataNew.addColumn('number', 'Weeknumber');
dataNew.addColumn('number', '00');
dataNew.addColumn('number', '01');
dataNew.addColumn('number', '02');
dataNew.addColumn('number', '03');
dataNew.addColumn('number', '04');
dataNew.addColumn('number', '05');
dataNew.addRows([
[1, 7, 4, 5, 0, 0, 1]
,[2, 12, 2, 9, 1, 1, 0]
,[3, 10, 0, 1, 1, 1, 0]
,[4, 4, 3, 0, 1, 0, 0]
,[5, 7, 5, 0, 0, 0, 0]
,[6, 6, 1, 0, 0, 0, 0]
,[7, 11, 4, 0, 0, 0, 0]
,[8, 11, 2, 0, 0, 0, 1]
]);
var options = {
title: 'title',
hAxis: {
ticks: dataNew.getDistinctValues(0),
title: 'Weeknumber'
},
vAxis: {
title: 'Tickets'
},
trendlines: {
0: {
type: 'polynomial',
degree: 3,
visibleInLegend: true,
pointSize: 20,
opacity: 0.1
}
},
width: 750,
height: 500,
};
var slaChart = new google.visualization.ColumnChart(
document.getElementById('ticketsSLA'));
slaChart.draw(dataNew, options);
});

Google Visualization: Chart Editor Error

I am try the Chart with a Google Visualization Chart when I click on OK nothing happens and the console displays the error:
TypeError: a is not a function
The code I am using is below:
<script type="text/javascript">

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));
}
// you can set individual columns to be the default columns (instead of populating via the loop above) like this:

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 width = Math.min(document.documentElement.clientWidth, window.innerWidth || 0) + 'px';
chart.setOption('height', '200px');
chart.setOption('width', width);
chart.draw();
}
How do I get the chart to be redrawn once the OK button has been clicked?

the last argument for the 'ok' event, should be a reference to a callback function -- not data
see following snippet, getWrapper is passed as the callback
when it fires, use getChartWrapper
var chartEditor = new google.visualization.ChartEditor();
google.visualization.events.addListener(chartEditor, 'ok', getWrapper);
chartEditor.openDialog(chart, {});
function getWrapper() {
chart = chartEditor.getChartWrapper();
redrawChart();
}
see following working snippet...
google.charts.load('current', {
callback: drawChart,
packages: ['corechart', 'controls', 'charteditor']
});

CategoryFilter as column selector

I used the following example to create a drop down menu: https://jsfiddle.net/asgallant/WaUu2/ which makes it possible to select a column and then show the line on the graph.
But I also want to use a ChartRangeFilter but the problem is this method doesn't use a dashboard so I have no clue were to start to make everything work together. And most of the examples I found use this dashboard method.
I want it to approximately to be like this example http://jsfiddle.net/x7pyk55q/4/ but would like to keep filtering on the columns.
It would be nice if someone could provide me an example how to do it the right way. I'm a bit new when it comes to this.

you can use the ChartRangeFilter to set the view.rows
similar to how the CategoryFilter sets the view.columns
when the 'statechange' event fires on the ChartRangeFilter,
use it's state to filter the rows for the range selected,
then redraw the chart
the ChartRangeFilter should be drawn using the same data and view as the chart
and re-drawn when the CategoryFilter changes

<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="colFilter_div"></div>
<div id="chart_div"></div>
<div id="rngFilter_div"></div>
note:
recommend using loader.js to load the library, instead of jsapi
according to the release notes...
The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. Please use the new gstatic loader from now on.
<script src="https://www.gstatic.com/charts/loader.js"></script>
this will only change the load statement
google.charts.load('current', {packages:['controls','corechart']});
you can also include the callback in the load statement, as in the above snippet...
