Java script Google Chart division of the xas show unwanted distribution - javascript

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);
});

Problem when trying to implement a variable in a heatmap using highcharts

I am currently trying to plot the values of a thermographic (AMG8833) inside a heatmap using highcharts module. As the values update in real time, these values are being sent through a nodemcu board and received in the html file. It is very strange as when I try to plot the value by itself using: (this part of the code repeats for each pixel of the camera)
setInterval(function () {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var pixel_0 = parseFloat(this.responseText);
document.getElementById("pixel_0").innerHTML = pixel_0;
pixel_0.innerHTML = pixel_0;
}
};
xhttp.open("GET", "/pixels[0]", true);
xhttp.send();
}, 1000 );
and
<h3>"The value for pixel 0 is: " <span id="pixel_0"></span></h3>
It shows the value perfectly. The problem comes when I try to put this value inside the data for my heatmap:
$(function () {
$('#Thermographic_camera').highcharts({
chart: {
type: 'heatmap',
marginTop: 40,
marginBottom: 80,
plotBorderWidth: 8,

[7, 0, pixel_56],
[7, 1, pixel_57],
[7, 2, pixel_58],
[7, 3, pixel_59],
[7, 4, pixel_60],
[7, 5, pixel_61],
[7, 6, pixel_62],
[7, 7, pixel_63],
],
dataLabels: {
enabled: false,
color: '#000000'
}
}]
});
});
When I do so, I obtain the answer in the heatmap that the variable i am trying to put inside the heatmap is an [object HTMLSpanElement] and it does not put the actual value of the variables of each pixel.
Any clue on what could I be doing wrong?
Thank you very much for the help

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.

</html>

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
see following working snippet...
google.charts.load('current', {
callback: drawChart,
packages:['controls','corechart']
});
function drawChart() {
// Create our data table out of JSON data loaded from server.

note:
recommend using loader.js to load the library, instead of jsapi

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...

Area spline chart using Highchart

I'm using Jquery Flot to plot my charts, and now I want to pass a specific one to Highchart.
This is my Chart using Jquery Flot
var data1 = [
[gd(2014, 1, 1), 4], [gd(2014, 2, 1), 8], [gd(2014, 3, 1), 4], [gd(2014, 4, 1), 10],
[gd(2014, 5, 1), 4], [gd(2014, 6, 1), 16], [gd(2014, 7, 1), 15]];
var data2 = [

};
var data2013 = {

I'm trying convert this chart, to a highchart but I'm a little bit confusing because in highchart a spline is a type while in Jquery Flot its an option.
How far I did
var data1 = [
[gd(2014, 1, 1), 4], [gd(2014, 2, 1), 8], [gd(2014, 3, 1), 4], [gd(2014, 4, 1), 10],
[gd(2014, 5, 1), 4], [gd(2014, 6, 1), 16], [gd(2014, 7, 1), 15]];
var data2 = [
[gd(2013, 1, 1), 3], [gd(2013, 2, 1), 5], [gd(2013, 3, 1), 3], [gd(2013, 4, 1), 11],
[gd(2013, 5, 5), 4], [gd(2013, 6, 1), 13], [gd(2013, 7, 1), 9], [gd(2013, 8, 1), 5],
[gd(2013, 9, 1), 2], [gd(2013, 10, 1), 3], [gd(2013, 11, 1), 2], [gd(2013, 12, 1), 1]];
$('#flot-dashboard-chart').highcharts('StockChart', {
rangeSelector: {
inputEnabled: $('#flot-dashboard-chart').width() > 480,
selected: 1
},
title: {
text: 'AAPL Stock Price'
},
colors: ['#1ab394'],
plotOptions: {
area: {
color: '#1ab394',
fillColor: '#1ab394'
}
},
series: [{
name: 'AAPL Stock Price',
data: data1,
type: 'areaspline',
threshold: null,
tooltip: {
valueDecimals: 2
},
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
}
}]
});
function gd(year, month, day) {
return new Date(year, month - 1, day).getTime();
}
But is very different the result. I'm reading the API for more information, but some options are in different places.
Can someone help me plot a graph using highchart ?
UPDATE
I'm getting close

[gd(2014, 5, 1), 4], [gd(2014, 6, 1), 16], [gd(2014, 7, 1), 15]];
var data2 = [

$('#container').highcharts({

},

data: [[1, 4], [2, 8], [3, 4], [4, 10], [5, 4], [6, 16], [7, 15]]
}, {
name: 'Receitas 2013',
data: [[1, 3], [2, 5], [3, 3], [4, 11], [5, 4], [6, 13], [7, 9], [8, 5], [9, 2], [10, 3], [11, 2], [12, 1]]
}]
});
});
function gd(year, month, day) {
return new Date(year, month - 1, day).getTime();
}

Why don't you just set the categories of the xAxis to an array containing the months as follows :
xAxis: {
categories: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec']
}
And then set your data using simple arrays :
var data1 = [4,8,4,10,4,16,15];
var data2 = [3,5,3,11,4,13,9,5,2,3,2,1];
Maybe that's not what you need, but take a look at the result and tell me what you think: http://jsfiddle.net/yohanrobert/T3Dpf/1/
EDIT
If you still want to use dates within your data arrays, what you could do is to create a xAxis with type set to 'datetime' for the first series like this:
{
type: 'datetime',
dateTimeLabelFormats: {
month: '%b' // Display months as labels ( 'Jan', 'Feb', ...)
},
showLastLabel: false, // If not set to false, displays 'Jan' at the end of the xAxis
tickInterval: 24 * 3600 * 1000 * 30.4 // Displays tick for each month
}
and then add one hidden xAxis for each new series:
{
type: 'datetime',
labels: {
enabled: false // Remove the label
},
tickWidth: 0, // Remove the ticks
lineWidth: 0 // Remove the axis line
}
Finally, you will need to set the extremes for the these series to go from January to December.
Here is an example with three series: http://jsfiddle.net/yohanrobert/T3Dpf/3/
This might not be the easiest way though.

Tooltip issue on adjacent Highchart charts

An issue I have noticed when you put two charts side by side in highcharts is that the tooltip function will work for the first chart but not the other. My guess that is that although the charts "look" like they are next to each other ... but in fact chart 1 is actually on top of chart 2. A good example of this is as follows: http://jsfiddle.net/F3pts/7/
Other example that will yield the same issue:
var options = {
chart: {
renderTo: 'container',
animation: true
},
xAxis: [{
type: 'datetime',
width :320,
}, {
type: 'datetime',
offset: 0,
width :200,
left: 380
}],
yAxis: [{
lineWidth: 2,
offset: 0,
tooltip: {
enabled: true,
formatter: function () {
return this.value;
}
}
},
],
series: [{
xAxis: 0,
name: 'Some line',
data: [
[Date.UTC(2010, 0, 1), 3],
[Date.UTC(2010, 0, 2), 7],
[Date.UTC(2010, 0, 3), 5],
[Date.UTC(2010, 0, 6), 6],
[Date.UTC(2010, 0, 7), 4],
[Date.UTC(2010, 0, 8), 5]
],
}, {
name: 'bar1',
xAxis: 1,
data: [
[Date.UTC(2010, 0, 1), 5],
[Date.UTC(2010, 0, 2), 6],
[Date.UTC(2010, 0, 3), 7],
[Date.UTC(2010, 0, 6), 4],
[Date.UTC(2010, 0, 7), 3],
[Date.UTC(2010, 0, 8), 4]
],
}, {
name: 'bar2',
xAxis: 1,
data: [
[Date.UTC(2010, 0, 1), 5],
[Date.UTC(2010, 0, 2), 8],
[Date.UTC(2010, 0, 3), 5],
[Date.UTC(2010, 0, 6), 6],
[Date.UTC(2010, 0, 7), 4],
[Date.UTC(2010, 0, 8), 3]
],
}]
};
var chart = new Highcharts.Chart(options);
Any ideas as to how ALL tooltips can be displayed? Kinda defeats the purpose if only one of these is available...
Regards and thanks for your time

Tooltip doesn't work, because of missconfigured chart:
tooltip: {
pointFormat: function () {
return "";
}
},
pointFormat should be string, not a function.
Anyway, there is stil la problem with tooltip position, see #2062.

Google Chart API Control range and snapToData issues

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!

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]
