can you please help me hide the tooltip (equation) on the trendline on the google chart on this page ?
Thanks
Here are the chart options I am using :
var options = {
title: 'Weight of pro surfer vs. Volume of his pro model',
hAxis: {title: 'Weight (kg)', minValue: 53, maxValue: 100}, //55
vAxis: {title: 'Volume (l)'}, //, minValue: 20, maxValue: 40}, //20
legend: 'none',
colors: ['#000000'],
series: {
1: { color: '#06b4c8' },
2: { color: '#575e6a' }
},
legend: {position: 'top right', textStyle: {fontSize: 8}},
chartArea: {width: '60%'},
//tooltip:{trigger:'none'}, //it hides all tooltips on the whole graph
trendlines: { 0: {//type: 'exponential',
visibleInLegend: true,
color: 'grey',
lineWidth: 2,
opacity: 0.2,
tooltip:{trigger:'none'}, //does nothing
labelInLegend: 'Linear trendline\n(Performance)'
}
} // Draw a trendline for data series 0.
};
If I add tooltip:{trigger:'none'}, before trendlines it hides the tooltips of the whole graph.
It has been implemented but not documented yet:
trendlines: {0: {tooltip: false}}
Only solution I was able to make is replacing the text of the tooltips from trendline. This example makes use of jquery, so if you are able to use jquery you can use:
google.visualization.events.addListener(chart, 'onmouseover', function(e){
$('svg *:contains("* x")').each(function(){
$(this).text('')
})
})
If not, it should be possible to replicate with pure js, but that´s the main idea: find the tooltips that have the formula attached, and replace the text with nothing
Here is a working example: http://jsfiddle.net/juvian/aapdjbpt/

I am using google chart's combo stacked bar. I want to display explicit values for h-axis, so I used ticks option. But, after using this option, my graph is displaying all bar values at once along the h-axis. But, I want to limit the bars to let's say 5 at a time and display the rest dynamically by sliding the charRangeFilter. The bars are almost appearing as straight lines when I use ticks option as shown in the image. Could some help me in resolving this issue? Any help is highly appreciated
Below is the code for the chart options
let hTicks = new Array<Date>(); // I already populated this array with Dates
let chart = new google.visualization.ChartWrapper({
'chartType': 'ComboChart',
'containerId': 'chartRangeFilter_chart_div',
'options': { .
// Use the same chart area width as the control for . axis alignment.
'width': '100%',
'height': '100%',
'hAxis': { 'title': 'DATES', 'gridlines': { 'color': 'transparent' }, 'ticks': hTicks, 'slantedText': true, 'slantedTextAngle': hTicks.length <= 10 ? 45 : 90 },
'legend': 'none',
'vAxis': { 'title': 'CABINS', 'viewWindow': { 'min': 0, 'max': (Number(cabinTotal) * 1.5) } },
'seriesType': 'bars',
'chartArea': { 'height': '50%', 'width': '85%' },
'bar': { 'groupWidth': '15%' },
'series': { 4: { 'type': 'line' } },
'isStacked': true,
'colors': ['#95d631', '#d7d7d7', '#f44336', '#00bcd4', '#ffc107']
}
Below are the charts
Chart with Tick option Chart Without Tick option
Solved by updating the ticks dynamically as the user slides the chartFilter
I'm trying to change the font size for the main title and axis titles but I cannot with this code:
var options = {
title: 'Ratio de supervivencia de aerolíneas europeas',
chartArea:{
top: 20,
bottom: 50,
height: '75%'
},
width: 800,
height: 600,
hAxis: {title: 'Nº total de aerolíneas históricas', titleFontSize: 24},
vAxis: {title: 'Ratio de supervivencia', format: 'percent', maxValue: 0.7, titleFontSize: 24},
bubble: {textStyle: {fontSize: 11}}
};
Could someone help me?
Thanks in advance & regards,
Luis
there is no option for --> titleFontSize
instead, use the option for --> titleTextStyle
e.g.
hAxis: {
titleTextStyle: {
fontSize: 24
}
}

I am using column google chart. I need to change the direction of column key which is highlighted into red circle in image below.
So what I want to achieve
Is there any property so I can change the direction like top, bottom or left side so it displayed properly (Revenue) as of now it display (R...).
If direction cannot be changed, then how can I remove this from charts
What you need is the property called chartArea
You can control how much area from top, right, bottom or left to be shown.
Here chart area is area of only the chart, excluding label, legend or any other value other than the chart itself. You can reduce the chart area so that label/legend can come completely.
chartArea: {
height: '500',
left: 0,
right: 0,
top: 30,
bottom: 0
},
Regarding the legend positioning, you can change place of legend using
legend: {
position: 'left'
}
To remove legends altogether use
legend:{position: 'none'}
See below snippet or this JSFIDDLE to see how it works.
google.charts.load('current', {
'packages': ['corechart']
});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Submitter', 'Count'],
['Service', 168],
['NAME 1', 42],
['NAME 2', 36],
['NAME 3', 35],
['NAME 4', 34],
['NAME 5', 30],
['NAME 6', 24],
['NAME 7', 21],
['NAME 8', 18]
]);
var options = {
pieSliceText: 'percentage',
legend: {
position: 'none'
},
height: '500',
chartArea: {
height: '500',
left: 0,
right: 0,
top: 30,
bottom: 0
},
};
var chart = new google.visualization.PieChart(document.getElementById('chart6_div'));
chart.draw(data, options);
}

Am new to PHP coding & have a few google charts working. All of these charts I've generated so far are based on (date,number of event occurrences) type of chart. I'm trying to plot a google chart whose data is the output of SQL query.
The output of SQL query looks as below
|SERIES|DATE_1|DATE_2|DATE_3|
|a|2|3|
|b|4|6|
|c|7|8|
Both SERIES & DATE_1 can vary. That is to say, based on various conditions in the SQL query, the number of DATE_ can be vary & so can the SERIES.
I would then have to pass this output to the google chart plot code.
Here is what i've tried coding so far
$link = mysql_connect("localhost", "user", "pass");
$dbcheck = mysql_select_db("database");
if ($dbcheck) {
$chart_array_1[] = "['MY_DATE','MY_NAME','#NUM_OCCURENCES']";
$result = mysql_query($sql);
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$my_date=$row["MY_DATE"];
$my_ins=$row["MY_NAME"];
$my_count=$row["MY_COUNT"];
$chart_array_1[]="['".$my_date."','".$my_ins."',".$my_count."]";
}
}
}
mysqli_close($link);
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart']});
// 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_1 = google.visualization.arrayToDataTable([<?php echo (implode(",", $chart_array_1)); ?>])
var options = {

},

height:'70%'
},

I'm unable to plot the graph. I get the error "Data column(s) for axis #0 cannot be of type string×". Could someone please help me here.
I'd like to see a,b,c etc as separate series each while the date goes on to the X-Axis. Please note am after generating data dynamically using SQL query & not a static array which most examples demonstrate. Could someone please help?
Managed to implement thing a different way. Hence this question can be ignored.
I'm using ExtJS3 and i want to put this chart into a panel with a dynamic store
http://dev.sencha.com/deploy/ext-3.4.0/examples/chart/pie-chart.html
I tried to include this chart into my panel code but it didn't work.
Does anybody has a solution or an example for a chart included into a panel in ExtJS3
Thank you
I used your example to generate the chart using a dynamic store:
Ext.chart.Chart.CHART_URL = 'http://dev.sencha.com/deploy/ext-3.4.0/resources/charts.swf';
Ext.onReady(function(){
var store = new Ext.data.JsonStore({
url: "sample_data.php",
root: 'results',
fields: [
{name: 'season'},
{name: 'total'}
]
});
new Ext.Panel({
width: 400,
height: 400,
title: 'Pie Chart with Legend - Favorite Season',
renderTo: 'container',
items: {
store: store,
xtype: 'piechart',
dataField: 'total',
categoryField: 'season',
//extra styles get applied to the chart defaults
extraStyle:
{
legend:
{
display: 'bottom',
padding: 5,
font:
{
family: 'Tahoma',
size: 13
}
}
}
}
});
});
where http://dev.sencha.com/deploy/ext-3.4.0/resources/charts.swf is the target where you can find the chart and sample_data.php returns the following json:
{"results":[
{"total":"150","season":"Summer"},
{"total":"245","season":"Fall"},
{"total":"117","season":"Winter"},
{"total":"184","season":"spring"}
]}
Note: This should normally be set to a local resource.
Hope this helps.
