I'm using google visualization for bubble chart, data to x axis and Y axis is dynamic. I'm facing issue here is that bubbles get cut-off and there size is also not uniform.
using following options
options = {
'title': 'Chart',
'width': '100%',
'height': 550,
legend: {position: 'right'},
vAxis: {
title: 'Score',
viewWindow: {
min: 0,
max: 5
},
baselineColor: {
color: '#4c78c6',
},
sizeAxis : {minValue: 0, maxSize: 15},
ticks: [1, 2, 3, 4, 5]
},
hAxis: {
title: 'Years',
baselineColor: {
color: '#4c78c6',
}
},
sizeAxis : {minValue: 0, maxSize: 15},
bubble: {
textStyle: {
color: 'none',
}
},
tooltip: {
isHtml: true,
},
colors: colors,
chartArea: { width: "30%", height: "50%" }
};
EDIT data passed to
var rows = [
['ID','YEAR','SCORE', 'AVG1', 'AVG']
['Deka marc', 2.5, 5, '76-100%', 100]
['Max cala', 28.2,3.4,'76-100%', 77]
['shane root',4.2, 1, '0-25%', 0]
]
var data = google.visualization.arrayToDataTable(rows);
from above array I'm removing element 3 on hover as do not wish to show in tooltip. AVG1 column is for legend
getting o/p like this
use
var rangeX = data.getColumnRange(1);
to know the range of column
and then use
hAxis: {
viewWindow: {
min: rangeX.min-10,
max: rangeX.max+10
}
},
}
do similarly for yAxis
https://jsfiddle.net/geniusunil/nt4ymrLe/4/
Add inside hAxis the viewWindow option.
This is a sample code:
viewWindow: {
min: 0,
max: 40
}
You can change max according your biggest value in your dataset you want to show. I mean if is 30 (as in your example) you can set max: 40, or if is 75 you can set max equal to 85.
JSfiddle here.
to find the range of each axis dynamically, use data table method --> getColumnRange
then you can use the ticks option to increase the range.
var rangeX = data.getColumnRange(1);
var ticksX = [];
for (var i = (Math.floor(rangeX.min / 10) * 10); i <= (Math.ceil(rangeX.max / 10) * 10); i = i + 10) {
ticksX.push(i);
}
var rangeY = data.getColumnRange(2);
var ticksY = [];
for (var i = Math.floor(rangeY.min) - 1; i <= Math.ceil(rangeY.max) + 1; i++) {
ticksY.push(i);
}
to make the size of the bubble uniform, set minSize & maxSize to the same value.
sizeAxis : {minSize: 15, maxSize: 15},
see following working snippet...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var rows = [
['ID','YEAR','SCORE', 'AVG1', 'AVG'],
['Deka marc', 2.5, 5, '76-100%', 100],
['Max cala', 28.2,3.4,'76-100%', 77],
['shane root',4.2, 1, '0-25%', 0]
];
var data = google.visualization.arrayToDataTable(rows);
var rangeX = data.getColumnRange(1);
var ticksX = [];
for (var i = (Math.floor(rangeX.min / 10) * 10); i <= (Math.ceil(rangeX.max / 10) * 10); i = i + 10) {
ticksX.push(i);
}
var rangeY = data.getColumnRange(2);
var ticksY = [];
for (var i = Math.floor(rangeY.min) - 1; i <= Math.ceil(rangeY.max) + 1; i++) {
ticksY.push(i);
}
var options = {
title: 'Chart',
width: '100%',
height: 550,
legend: {position: 'right'},
vAxis: {
title: 'Score',
baselineColor: {
color: '#4c78c6',
},
sizeAxis : {minSize: 15, maxSize: 15},
ticks: ticksY
},
hAxis: {
title: 'Years',
baselineColor: {
color: '#4c78c6',
},
ticks: ticksX
},
sizeAxis : {minSize: 10, maxSize: 10},
bubble: {
textStyle: {
color: 'none',
}
},
tooltip: {
isHtml: true,
},
//colors: colors,
chartArea: { width: "30%", height: "50%" }
};
var chart = new google.visualization.BubbleChart(document.getElementById('chart_div'));
chart.draw(data, options);
});
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div"></div>
Add 10% of the difference between the max and min
vAxis: {
viewWindow: {
min: rangeY.min - ((+rangeY.max - rangeY.min) * 10 / 100),
max: rangeY.max + ((+rangeY.max - rangeY.min) * 10 / 100)
}
},
hAxis: {
viewWindow: {
min: rangeX.min - ((+rangeX.max - rangeX.min) * 10 / 100),
max: rangeX.max + ((+rangeX.max - rangeX.min) * 10 / 100)
}
},
I'm trying to create a chart with multiple AxisX with a javascript library (google or chartjs preferable).
I have made an example on excel to illustrate what i'm looking for, here is the example:
I've tried the next fiddle but obviously without success.
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawVisualization);
function drawVisualization() {
// Some raw data (not necessarily accurate)
var data = google.visualization.arrayToDataTable([
['Month', ['Activo, inactivo'], ['Activo, inactivo'], ['Activo, inactivo'], ['Activo, inactivo']],
['Gestor A', [165,100], [938,800], [522,100], [998, 1000]],
['Gestor B', [135,90], [1120,1000], [599,1000], [1268,700]],
['Gestor C', [157,70], [1167,800], [587,400], [807,900]],
['Gestor D', [139,160], [1110,1200], [615,500], [968,1000]],
['Gestor E', [136,200], [691,800], [629,700], [1026,1200]]
]);
var options = {
title : 'Monthly Coffee Production by Country',
vAxis: {title: 'Cups'},
hAxis: {title: ['Month']},
seriesType: 'bars',
series: {5: {type: 'line'}}
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
google charts does not offer multiple group labels
but you can add them manually on the chart's 'ready' event
see following working snippet,
the position of the x-axis labels are used to draw the group labels and lines
google.charts.load('current', {

I've managed to implement a continuous axis google chart on my page and got it formatted the way I want it. Now my requirements have changed and I'm trying to load this chart from a CSV as opposed to hard coded and randomly generated data.
I've confused myself and gotten in over my head on how to convert my working chart into pulling from a CSV. I'm going to post a few things here,
One of my other charts that utilizes a CSV, this is what I was trying to recreate
My working continuous axis chart running off hard coded data
My current state of the chart now that I've tried to implement the change.
Here is #1:
function drawPieVisualization() {

// transform the CSV string into a 2-dimensional array
var arrayData = $.csv.toArrays(csvString, {onParseValue: $.csv.hooks.castToScalar}, {onParseValue: $.csv.hooks.castToScalar});
// this new DataTable object holds all the data
var data = new google.visualization.arrayToDataTable(arrayData);

The bottom part 'runOnce' in both #2 and #3 are to change the slider control on the chart from 1 day - 1 week - or 1 month of range on the chart, for clarification.
My chart is currently giving me the errors:
One or more participants failed to draw(). (Two of these)
And
The filter cannot operate on a column of type string. Column type must
be one of: number, date, datetime or timeofday. Column role must be
domain, and correlate to a continuous axis.
the second error message reveals that arrayToDataTable
creates the first column as --> type: 'string'
instead of --> type: 'date'
use a DataView to convert the string to a date
you can create calculated columns in a data view using method --> setColumns
use view in place of data when drawing the dashboard
see following snippet...
$.get("Source7Days.csv", function(csvString) {
var arrayData = $.csv.toArrays(csvString, {onParseValue: $.csv.hooks.castToScalar}, {onParseValue: $.csv.hooks.castToScalar});
// this is a static method, "new" keyword should not be used here
var data = google.visualization.arrayToDataTable(arrayData);
// create view
var view = new google.visualization.DataView(data);
view.setColumns([
// first column is calculated
{
calc: function (dt, row) {
// convert string to date
return new Date(dt.getValue(row, 0));
},
label: data.getColumnLabel(0),
type: 'date'
},
// just use index # for second column

i'm trying to use Google Chart API for building an Waterfall chart. I noticed that Candlestick/Waterfall charts are not supporting the annotations.
See this jsfiddle sample
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Category');
data.addColumn('number', 'MinimumLevel');
data.addColumn('number', 'MinimumLevel1');
data.addColumn('number', 'MaximumLevel');
data.addColumn('number', 'MaximumLevel1');
data.addColumn({type: 'number', role: 'tooltip'});
data.addColumn({type: 'string', role: 'style'});
data.addColumn({type: 'number', role: 'annotation'});
data.addRow(['Category 1', 0 , 0, 5, 5, 5,'gray',5]);
data.addRow(['Category 2', 5 , 5, 10, 10, 10,'red',10]);
data.addRow(['Category 3', 10 , 10, 15, 15, 15,'blue',15]);
data.addRow(['Category 4', 15 , 15, 10, 10, 10,'yellow',10]);
data.addRow(['Category 5', 10 , 10, 5, 5, 5,'gray',5]);
var options = {
legend: 'none',
bar: { groupWidth: '60%' } // Remove space between bars.
};
var chart = new google.visualization.CandlestickChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
I would like to put the value of the 5th column at the top of every candlestick.
It should look like this :
Is there a way to do this?
Thanks
I add annotations to candlestick charts by adding annotations to a hidden scatter plot. You can set exactly where you want the annotations to sit by changing the plot.
google.charts.load('current', { 'packages': ['corechart'] });
google.charts.setOnLoadCallback(drawChart);
function drawChart() {

just so happens, i ran into the same problem this week
so I added my own annotations, during the 'animationfinish' event
see following working snippet...

I have a page that displays data using LineChart with a ChartRangeFilter control.

And here's a working JSFiddle.
Here the control starts from Jan 1. When I change start range to Jan 2, the graph date starts to show from Feb. I could not identify the reason for this. Can anyone help me in this? In the end range it is working fine it seems.
In this example, on 'statechange' -- the value for the begin and end months, for the selected chart range, are modified to ensure data points are plotted.
The chart is then redrawn with updated options.

It is because you only have one value for January (1st the jan) and when you set the start range to jan 2 the next value in your data if for Feb 1st.
The month value for month in the data object is zero-based.
