Google bar chart display day issue - javascript

My fiddle : https://jsfiddle.net/vbdy7fLe/1/
I'm trying to use google column chart and display multiple fields of data and by date. But I'm not sure why it doesn't display 02 Jan 2015 and 04 Jan 2015.
The data is there and here is my js code :
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['date', 'person A', 'person B'],
[new Date(2015, 0, 1), 1, 4, ],
[new Date(2015, 0, 2), 1, 4, ],
[new Date(2015, 0, 3), 6, 11, ],
[new Date(2015, 0, 4), 10, 5, ],
[new Date(2015, 0, 5), 10, 5, ]
]);
var options = {
chart: {
title: 'Meeting by weeks'
},
bars: 'vertical',
height: 400,
colors: ['#3498db', '#9b59b6', '#16a085'],
hAxis: {
format: 'dd MMM yyyy'
}
};
var chart = new google.charts.Bar(document.getElementById('chart_div'));
chart.draw(data, google.charts.Bar.convertOptions(options));
}

It's not showing because googles function to draw the chart has decided that there is not enough space to write text on every single column.
Either try the setting for hAxis.slantedTextor try making your chart wider.

Cannot remove AM PM format from Google Chart date

I have this Google chart and I cannot get the lower part (where date and time is) to show hours from 00 to 23, it always shows it with AM/PM.
I mean the area that is always visible, the other value that apepars on tooltip was formated OK, but not that lower part.
What am I doing wrong ?
I tried by that dateformatter code (it only seems to affect the tooltip date value).
And by this (not doing anything):
hAxis: {
format: 'dd/MM/yyyy HH:mm',
gridlines: {count: 15}
},
The jsfiddle
<script>
google.charts.load('current', {'packages':['line', 'corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var chartDiv = document.getElementById('chart_div');
var data = new google.visualization.DataTable();
data.addColumn('datetime');
data.addColumn('number', "Temp");
data.addColumn('number', "Humidity");
data.addRows([
[new Date(2020, 11, 04, 15, 00), 25.50, 62.76],
[new Date(2020, 11, 04, 15, 10), 25.58, 62.63],
[new Date(2020, 11, 04, 15, 20), 25.60, 62.47],
[new Date(2020, 11, 04, 15, 30), 25.60, 62.38],
[new Date(2020, 11, 04, 15, 40), 25.62, 62.16],
[new Date(2020, 11, 04, 15, 50), 25.60, 62.00],
[new Date(2020, 11, 04, 16, 00), 25.60, 61.79],
[new Date(2020, 11, 04, 16, 10), 25.77, 61.72],
[new Date(2020, 11, 04, 16, 20), 25.97, 60.93],
[new Date(2020, 11, 04, 16, 30), 26.07, 60.38],
]);
// give date a certain format
var dateFormatter = new google.visualization.DateFormat({pattern: 'dd/MM/yyyy HH:mm'});
dateFormatter.format(data, 0);
var materialOptions = {
// trying to format date/time on lower line, not working :/
hAxis: {
format: 'dd/MM/yyyy HH:mm',
gridlines: {count: 15}
},
legend: {position: 'none'},
series: {
// Gives each series an axis name that matches the Y-axis below.
0: {axis: 'Temp'},
1: {axis: 'Humidity'},
},
axes: {
y: {
Temp: {label: 'Temps (Celsius)', range: {max: 15, min: 40 }},
Humidity: {label: 'Humidity (%)', /*range: {max: 30, min: 90 }*/},
},
},
colors: ['#B00000', '#1bdec4']
};
function drawMaterialChart() {
var materialChart = new google.charts.Line(chartDiv);
materialChart.draw(data, materialOptions);
}
drawMaterialChart();
}
</script>
when drawing a material chart,
need to convert the options using static method --> google.charts.Line.convertOptions
materialChart.draw(data, google.charts.Line.convertOptions(materialOptions));
this will ensure the supported options are included properly,
see following working snippet...
google.charts.load('current', {
'packages': ['line', 'corechart']
});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var chartDiv = document.getElementById('chart_div');
var data = new google.visualization.DataTable();
data.addColumn('datetime');
data.addColumn('number', "Temp");
data.addColumn('number', "Humidity");
data.addRows([
[new Date(2020, 11, 04, 15, 00), 25.50, 62.76],
[new Date(2020, 11, 04, 15, 10), 25.58, 62.63],
[new Date(2020, 11, 04, 15, 20), 25.60, 62.47],
]);
// give date a certain format
var dateFormatter = new google.visualization.DateFormat({
pattern: 'dd/MM/yyyy HH:mm'
});
dateFormatter.format(data, 0);
var materialOptions = {
// trying to format date/time on lower line, not working :/
hAxis: {
format: 'dd/MM/yyyy HH:mm',
gridlines: {
count: 15
}
},
legend: {
position: 'none'
},
series: {
// Gives each series an axis name that matches the Y-axis below.
0: {
axis: 'Temp'
},
1: {
axis: 'Humidity'
},
},
axes: {
y: {
Temp: {
label: 'Temps (Celsius)',
range: {
max: 15,
min: 40
}
},
Humidity: {
label: 'Humidity (%)',
range: {max: 30, min: 90 }
},
},
},
colors: ['#B00000', '#1bdec4']
};
function drawMaterialChart() {
var materialChart = new google.charts.Line(chartDiv);
materialChart.draw(data, google.charts.Line.convertOptions(materialOptions));

Escape "GMT" for Google Charts Timestamp

I have Google Charts set up with the hAxis as a timeline. My client wants to display the time in 24 hour time, with the GMT offset printed along side, and the date. My code is pretty simple, but the "GMT" label is generating an interesting side effect.
Here's my format code: "format": 'H:MM '+' GMT'+$scope.offset.toString()+'\r\n MM/dd/yyyy' but the result is:
6:03 AD3T+7
03/21/2016
AD3T from "GMT", which is probably the result of passing G (to get AD?) and M to get the month (3), and the T apparently has no effect.
My question is, in the Google Charts JSON object, how can I format the time stamp to have a human-readable label of "GMT" and the offset? Do I need to escape "GMT"? If so, how?
There are a couple different ways to apply formatting, easiest being hAxis.format
it follows the ICU pattern set
See table under Detailed Description for all the patterns available.
I think this may get you close, including the offset.
'H:MM ZZZZ \r\n MM/dd/yyyy'
You can also provide your own tick marks.
Which means you can apply your own custom format generated in JavaScript.
The following example assumes this formatting has already occurred.
Provide the typical object google accepts for a column value in an array
one for each tick mark you need displayed
{v: new Date(2013, 4, 5, 3, 6, 0, 0), f: '3:05 GMT-04:00 \r\n 05/05/2013'}
Following are two examples, one using hAxis.format, the other ticks ...
google.charts.load('current', {
callback: drawChart,
packages: ['corechart']
});
function drawChart() {
var data = [
['Date', 'Value'], //provide custom formatting
[ {v: new Date(2013, 4, 4, 1, 3, 0, 0), f: '1:05 GMT-04:00 \r\n 05/04/2013'}, 38177],
[ {v: new Date(2013, 4, 5, 3, 6, 0, 0), f: '3:05 GMT-04:00 \r\n 05/05/2013'}, 38705],
[ {v: new Date(2013, 4, 12, 2, 4, 0, 0), f: '2:05 GMT-04:00 \r\n 05/12/2013'}, 38210],
[ {v: new Date(2013, 4, 13, 4, 8, 0, 0), f: '4:05 GMT-04:00 \r\n 05/13/2013'}, 38029],
[ {v: new Date(2013, 4, 19, 8, 9, 0, 0), f: '8:05 GMT-04:00 \r\n 05/19/2013'}, 38823],
[ {v: new Date(2013, 4, 23, 2, 4, 0, 0), f: '2:05 GMT-04:00 \r\n 05/23/2013'}, 38345],
[ {v: new Date(2013, 4, 24, 1, 1, 0, 0), f: '1:05 GMT-04:00 \r\n 05/24/2013'}, 38436],
[ {v: new Date(2013, 4, 30, 6, 8, 0, 0), f: '6:05 GMT-04:00 \r\n 05/30/2013'}, 38447]
];
var tickMarks = [];
for (var i = 1; i < data.length; i++) {
tickMarks.push(data[i][0]);
i = i + 1;
}

Multiple trendlines in Google Charts

I need to add multiple trendlines to my google line chart but I just can't figure out how to do it with more than one line.
Here is my code example with a single line based on a date and value to build the chart:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
function drawMultipleTrendlineChart() {
var chart;
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sales value');
data.addRow([new Date(2013, 3, 11), 10]);
data.addRow([new Date(2013, 4, 02), 650]);
data.addRow([new Date(2013, 5, 03), 55]);
data.addRow([new Date(2013, 6, 04), 95]);
data.addRow([new Date(2013, 7, 05), 400]);
data.addRow([new Date(2013, 8, 06), 600]);
data.addRow([new Date(2014, 0, 07), 800]);
data.addRow([new Date(2014, 1, 08), 900]);
data.addRow([new Date(2014, 2, 09), 3127]);
var formatter = new google.visualization.NumberFormat({
fractionDigits: 2,
prefix: 'R$:'
});
formatter.format(data, 1);
var dateFormatter = new google.visualization.NumberFormat({
pattern: 'MMM yyyy'
});
dateFormatter.format(data, 0);
var chartHeight = 400;
var chartWidth = 600;
var chartOptions = {
tooltip:{isHtml: true},
trendlines: {
0: {color: 'red'}
},
title: 'Trendlines with multiple lines',
isStacked: true,
width: chartWidth,
height: chartHeight,
colors: ['#0000D8'],
hAxis: {
title: 'example title',
slantedText: false,
slantedTextAngle: 45,
textStyle: {
fontSize: 10
},
format: 'dd-MM-yyyy'
},
chartArea: {
left: 100,
top: 20,
width: (chartWidth - 10),
height: (chartHeight - 90)
}
};
chart = new google.visualization.LineChart(document.getElementById('multipleTrendChart'));
chart.draw(data, chartOptions);
}
google.load('visualization', '1', {packages:['corechart'], callback: drawMultipleTrendlineChart});
</script>
</head>
<body>
<div id="multipleTrendChart"></div>
</body>
I wan't to do it like this image:Image_example
jsfiddle example: http://jsfiddle.net/w3ez9gwb/
Just add more columns of your data:
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sales value A');
data.addColumn('number', 'Sales value B');
data.addRows([
[new Date(2013, 3, 11), 100, 10],
[new Date(2013, 4, 02), 50, 650],
[new Date(2013, 5, 03), 70, 55],
[new Date(2013, 6, 04), 80, 95],
[new Date(2013, 7, 05), 50, 400],
[new Date(2013, 8, 06), 10, 600],
[new Date(2014, 0, 07), 20, 800],
[new Date(2014, 1, 08), 300, 900],
[new Date(2014, 2, 09), 100, 312]
]);
Then add the trendlines to your chart options like so:
var chartOptions = {
tooltip: {
isHtml: true
},
trendlines: {
0: {
color: 'red'
},
1: {
color: 'yellow'
},
},
...
};

Google chart line: how to connect dots properly using a continuous axes

I have a problem on a Google Chart line graph. I'm trying to use a continuous axis, but I obtain this:
As you can see, I'm not able to connecting dots using the X (date), but the dots are connect using the Y. How can I change this graph and obtain a "normal" graph?
The code that I've used is this one:
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Data');
data.addColumn('number', 'Prestazione');
data.addRows([
[new Date(2005, 05, 01), 9.17],
[new Date(2005, 07, 01), 9.2],
[new Date(2006, 07, 07), 8.7],
[new Date(2006, 04, 08), 8.84],
[new Date(2005, 10, 08), 9.09],
[new Date(2006, 06, 10), 8.58],
[new Date(2006, 06, 10), 8.66],
[new Date(2005, 07, 13), 9.2],
[new Date(2006, 09, 13), 8.8],
[new Date(2006, 07, 14), 8.71],
[new Date(2005, 07, 15), 8.7],
[new Date(2008, 01, 20), 8.50],
[new Date(2005, 05, 21), 9.0],
[new Date(2006, 05, 27), 8.6],
[new Date(2006, 06, 28), 8.7],
]);
var options = {
title: '',
pointSize: 5,
curveType: 'function',
legend: 'none',
explorer: {}
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div01'));
chart.draw(data, options);
}
This is because line chart in Google chart doesnt order the data by itself based on the x axis values.
If you want to have a continuous graph, you should sort the data based on x-axis value (timestamp in your case) and then pass it to Google charts.
You can use data.sort([{column: 0}]); for sorting it based on x-axis, Here column:0 indicates x-axis.https://developers.google.com/chart/interactive/docs/reference#DataTable_getSortedRows
If the value you are trying to pass is through some xml or json and it has null values inside it will not plot properly and will be scattered or as dotted lines in line graph so to plot them, have a condition to remove all null values and then it will plot correctly.

Make Specific Time Period X-Axis Flot Jquery

I want to make a chart that showing data with 4 month interval (3 period/year).
and i want the x-axis label showing the year and the period like image below:
http://i.stack.imgur.com/eerSy.png
what i've done so far :
var data = [[1262278800000,87.5],[1293814800000,750],[1325350800000,100],[1356973200000,25],[1371229200000,87.5],[1388422800000,0],[1388509200000,375],[1402765200000,100],[1419958800000,1000]];
var tahunsekarang=new Date(2015, 12, 31).getTime();
$.plot("#chartTabamaProduktifitas", [data], {
xaxis: { mode: "time",tickSize: [4, "month"] , timeformat: "%Y",panRange: [1262217600000, tahunsekarang]},
yaxis: {panRange: [0, 1500] },
pan: { interactive: true},
series: {lines: {show: true},points: {show: true}},
});
but since I made it pan: { interactive: true} so when i drag the chart, the tickline is always change value, it made the chartline not fit in the tick line
1) If you want fixed ticks when you drag the chart you have to give a fixed ticks array instead of the tickSize option.
2) To give the Roman number for the trimester you can use a tickFormatter function instead of the timeformat option.
New options object:
xaxis: {
mode: "time",
ticks: ticks,
tickFormatter: function (val, axis) {
var d = new Date(val);
var trimester = '';
for (var i = 1; i <= (1 + d.getMonth() / 4); i++){
trimester += "I";
};
return trimester + "<br>" + d.getFullYear();
},
panRange: [1262217600000, tahunsekarang]
},
