Im currently using ExtJs5 MVVM architecture and I require "sencha-chart" than "ext-chart" on the app.json file, Charts works fine but adding tooltip on the bar series im using doesn't work. No error logs.
I also check their example on sencha chart kitchensink (which chart tooltip is working) found out that they require "ext-chart" for that. My code for bar series with tooltip config:
series: [{
type: 'bar',
xField: 'name',
yField: ['data1'],
style: {
opacity: 0.80
},
highlight: {
fill: '#000',
'stroke-width': 20,
stroke: '#fff'
},
tips: {
trackMouse: true,
style: 'background: #FFF',
height: 20,
renderer: function(storeItem, item) {
this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data1') + '%');
}
}
}]
Is there something wrong with my codes?
Thanks
Your code needs one small change "tips" for EXTjs 5 becomes "tooltip."
tooltip: {
trackMouse: true,
style: 'background: #FFF',
height: 20,
renderer: function(storeItem, item) {
this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data1') + '%');
}
}
However, there are a lot of bugs with the EXTjs 5 charts. I had this same issue, and submitted a bug to Sencha:
http://www.sencha.com/forum/showthread.php?289313-Sencha-EXTjs-5-Charts-Broken-Tooltips
tooltip: {
trackMouse: true,
style: 'background: #FFF',
height: 20,
renderer: function(storeItem, item) {
this.setHtml(storeItem.get('name') + ': ' + storeItem.get('data1') + '%');
}
}
I used tooltip inplace of tips and this.setHtml() in place of this.setTitle() ,and it worked for me.

After a lot of try and error, trying to find a solution to this, I understood thanks to help of Eddy Verbruggen that there two unique way to add markers to mapbox map: by code inside of onMapReady() or programmatically.
But now, I find something that I can not solve: using exactly code indicated Declaring a map programmatically, when run the app appears errors originated in "TypeError: mapbox.show is not a function".
The code is:
`var mapbox = require("nativescript-mapbox");
var platform = require("platform");
var isIOS = platform.device.os === platform.platformNames.ios;
mapbox.show({
accessToken: 'here i wrote my own API ACCESS TOKEN',
style: street,
margins: {
left: 40, // default 0
right: 40, // default 0
top: 450, // default 0
bottom: isIOS ? 50: 0
},
center: { // optional without a default
lat: 52.3702160,
lng: 4.8951680
},
zoomLevel: 9.25,
showUserLocation: true,
hideAttribution: false,
hideLogo: false,
hideCompass: false,
disableRotation: false,
disableScroll: false,
disableZoom: false,
markers: [
{
id: 1,
lat: 52.3732160,
lng: 4.8941680,
title: 'Nice location',
subtitle: 'Really really nice location',
icon: 'res://cool_marker',
selected: true,
onTap: function(marker) { console.log("This marker was tapped"); },
onCalloutTap: function(marker) { console.log("marker was tapped"); }
}
]
}).then(
function(showResult) {
console.log("Mapbox show done for " + (showResult.ios ? "iOS" :
"Android") + ", native object received: " + (showResult.ios ?
showResult.ios : showResult.android));
},
function(error) {
console.log("mapbox show error: " + error);
}
)`
To clarify, the app is build from "tns create my-app-name --template tns-template-blank". I only added nativescript-mapbox plugin and insert code indicate in "Declaring a map programmatically" inside on home.js file.
I can't understand why appear that error, I'm sure that plugin was correctly installed. The app uses NS version 3.4.1 and nativescript-mapbox version 3.3.0, on Android.
We are using highcharts to plot multiple charts on a single HTML page.
However one/some of the chart throw highchart error and we like to capture those error and show different error to user.
For this highcharts do provide custom error handler. But this custom error handler does not provide information about specific chart throwing that error.
Here that JS Fiddle provided by highcharts, which works fine for a chart :
Highcharts.error = function (code, true) {
// See
https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
Highcharts.charts[0].renderer
.text('Chart error ' + code)
.attr({
fill: 'red',
zIndex: 20
})
.add()
.align({
align: 'center',
verticalAlign: 'middle'
}, null, 'plotBox');
};
http://jsfiddle.net/gh/get/library/pure/highslide-software/highcharts.com/tree/master/samples/highcharts/chart/highcharts-error/
Any idea how can I use this custom error handler per chart?
I'm using new Highcharts.Charts(options) to create new chart, but don't see way to specify error handler per chart.
Additional info: Charts are refreshed/appended using data through APIs. User that configures chart also configures refresh interval and query to use for chart.
Error handling in HighCharts does not make much sense. It would make more sense to pass the chart instance to Highcharts.error (like Kamil Kulig wrote) or to have an error event in chart.events. Anyways
here is a solution I came up with:
Create an array of errors:
var chartErrors = [];
Create an error handler which will push errors into the chartErrors. Error objects I'm making look like this: {"chartIndex": <chart index>, "errorCode": <error code>}. All charts are added to the Highcharts.charts array when they are created so we can use Highcharts.charts.length - 1 for the chartIndex.
Highcharts.error = function (code) {
// See https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
chartErrors.push({"chartIndex": Highcharts.charts.length - 1, "errorCode":code});
};
After initiating all charts we will have an array of errors. We can call forEach on this array and handle errors the way we want.
chartErrors.forEach(function(c) {
Highcharts.charts[c.chartIndex].renderer
.text('Chart error ' + c.errorCode)
.attr({
fill: 'red',
zIndex: 20
})
.add()
.align({
align: 'center',
verticalAlign: 'middle'
}, null, 'plotBox');
});
Working example:
Note: I've wrapped the code in a self invoking function to prevent leaking variables to global scope.
(function() {
var chartErrors = [];
Highcharts.error = function (code) {
// See https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
chartErrors.push({"chartIndex": Highcharts.charts.length - 1, "errorCode":code});
};

Highcharts error function is not adjusted to have a chart context as an argument, because it can be executed in different contexts too.
For example: error number 16 occurs when Highcharts/Highstock is loaded second time in the same page. It has nothing to do with the chart, because it depends on script importing only.
The workaround I found requires some searching and and a little bit of coding.
Refer to this live demo: http://jsfiddle.net/kkulig/a8nun9aL/
I found the place in the code responsible for throwing the error 10 (the one you used in your example). I overwrote this function (see this doc page for more information about overwriting in Highcharts: https://www.highcharts.com/docs/extending-highcharts/extending-highcharts) and added a chart variable (from Highcharts.Axis.prototype.setTickInterval scope) as the third argument:
if (
axis.positiveValuesOnly &&
!secondPass &&
Math.min(axis.min, pick(axis.dataMin, axis.min)) <= 0
) { // #978
H.error(10, 1, chart); // Can't plot negative values on log axis // MODIFIED LINE
}
It should be done for all errors you want to custom handle.
Now it can be used in custom Highcharts.error function:
Highcharts.error = function(code, stop, chart) {
// See https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
Highcharts.charts[0].renderer
.text('Chart error ' + code + " on chart titled: " + chart.title.textStr)
(...)
You can add your own property in chart constructor options and find it in chart.options object.
I'm using the LeafLet MarkerCluster plugin ( https://github.com/Leaflet/Leaflet.markercluster )
Does anyone know if it is possible to color the MarkerCluster Spiderfy line color dynamically?
For example, I can set other things dynamically like this:
markersFeatureLayer.eachLayer(function(layer) {
layer.feature.properties.line = 'green';
layer.setIcon(L.MyMarkers.icon({
icon: layer.feature.properties.myData.icon,
markerColor: layer.feature.properties['icon-color'],
iconColor: '#FFFFFF'
}));
mapClusterLayer.addLayer(layer);
});
Or this
mapClusterLayer = new L.MarkerClusterGroup({
maxClusterRadius: 2,
spiderfyDistanceMultiplier: 3,
removeOutsideVisibleBounds: false,
iconCreateFunction: function(cluster) {
return new L.DivIcon({
iconSize: [30, 30],
html: '<div style="text-align:center;color:#fff;background:' +
'green' + '">' + cluster.getChildCount() + '</div>',
});
}
});
I want each spider line to be equal to markerColor. So each will have a unique color.
Any ideas?
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">

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.
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/
