I created a chart with two y-axis and one x-axis and struggle to create tooltips with intersect = false, so it will start the tooltip when hovering over the line and not only the point of the chart
However, the whole settings for the tooltip, described on
https://www.chartjs.org/docs/latest/configuration/tooltip.html
Does not seem to have any effect for me. My code see below
I am using this code inside a NodeRed template node
\<canvas id="myChart" width=912 height =370\>\</canvas\>
\<script\>
var textcolor = getComputedStyle(document.documentElement).getPropertyValue('--nr-dashboard-widgetTextColor');
var gridcolor = '#E6E6E6';
var linecolors = \['#333F50','#B55A11', '#90C050'\]
var backgroundColor = \['#999FA7','#DAAC88', '#C7DFA7'\]
var ctx = document.getElementById('myChart').getContext('2d');
var chart = new Chart(ctx, {
// The type of chart we want to create
type: 'line',
// The data for our dataset
data: {
labels: {{{payload.labels}}},
datasets: [
{
label: 'Folie Länge Ist',
backgroundColor: backgroundColor[0],
borderColor: linecolors[0],
data: {{{payload.eins}}},
yAxisID: 'left-y-axis',
},
{
label: 'Folie Länge Soll',
backgroundColor: backgroundColor[1],
borderColor: linecolors[1],
data: {{{payload.zwei}}},
yAxisID: 'left-y-axis',
},
{
label: 'Aufwickler Durchmesser',
backgroundColor: backgroundColor[2],
borderColor: linecolors[2],
data: {{{payload.drei}}},
yAxisID: 'right-y-axis',
}
]
},
// Configuration options

display: true,
position: "top"
},
elements: {

pointStyle: 'circle',
radius: 0
},

}
},
plugins: {

}
},

yAxes: [
{
gridLines :{display:false},
id: 'left-y-axis',
type: 'linear',
position: 'left',
ticks: {
fontColor: linecolors[0],
callback: function(value, index, ticks) {
return new Intl.NumberFormat('de-DE').format(value);
}
}
},
{
gridLines :{zeroLineColor:gridcolor,color:gridcolor,lineWidth:1},
id: 'right-y-axis',
type: 'linear',
position: 'right',
ticks: {
fontColor:linecolors[2],
callback: function(value, index, ticks) {
return new Intl.NumberFormat('de-DE').format(value);
}
}
}
],
xAxes: [
{
ticks: {
autoSkip: true,
autoSkipPadding: 10,
maxRotation: 0,
minRotation: 0
}
}
]
}
}
});
\</script\>
Tried setting intersect = false, also enable = false just to test if these settings have an effect
I need to use the select state in a Treemap to change the color of the selected area (it works well for other charts like pie charts, bubble charts...). But the state seems to not be taken into account.
The demo is here : https://jsfiddle.net/vegaelce/0xuqvrg3/
I tried to use the settings described in the documentation (I tried "color" and "marker/fillColor") :
plotOptions: {
series: {
allowPointSelect: true,
states: {
hover: {
color: "#ff0000",
marker: {
fillColor: "#ff0000"
}
},
select: {
color: "#0000ff",
marker: {
fillColor: "#0000ff"
}
}
},
But no success... Any idea to achieve that please ?
Thanks in advance
I want to highlight fill-extrusion features when hovered over them.
The styling related to this is straight-forward using expressions and feature state, but I am having trouble retrieving the correct features.
There is code available online to change the feature state when hovered over, and it seems straight-forward enough, so I adapted it:
var hover_id = null;
const feature_state = { hover: true }
map.on('mousemove', '3d-buildings', (e) => {
// Get features under cursor, following render order
const features = map.queryRenderedFeatures(e.point);
// Check that features are not empty
if (features.length > 0) {
// Clean up previously hovered feature
if (hover_id) {
map.removeFeatureState({source: "composite", sourceLayer: 'building', id: hover_id});
}
// Set feature state of the new hovered feature
hover_id = features[0].id;
map.setFeatureState({source: 'composite', sourceLayer: 'building', id: hover_id}, feature_state);
console.log(hover_id)
}
});
While this works well initially, it stops working as soon as I tilt the camera using the right mouse button. After tilting, the foremost element no longer gets selected (something else seems to get selected and an ID gets printed out, but nothing shows up on the map and no error is thrown).
On a related note, the correct feature only gets selected after zooming in quite far - there is a large zoom range where the buildings already get rendered to the screen, but seem to not get picked up by queryRenderedFeatures. Is this expected behaviour?
Expected behaviour:
map.queryRenderedFeatures(...)[0] selects the foremost feature, independent of the camera tilt.
What could be a possible reason for the camera tilt influencing the feature selection? Is this a bug or am I misusing the API?
I think the issue you’re facing has nothing to do with tilt but with the fact that you’re adding and removing the state instead of changing the value of the state. The state must be declared in the layer definition, change the color with a expression, and then you only need to change the value of the state.
Here you have a fiddle I have created to show how to change color of fill extrusions on mouse over/out
Relevant code is this:
let mapConfig = {
NYC: {
origin: [-74.044514, 40.689259, 39],
center: [-74.0137, 40.70346, 0],
zoom: 16.2,
pitch: 60,
bearing: 35
}
}
mapboxgl.accessToken = 'PUT YOUR TOKEN HERE';
let point = mapConfig.NYC;
var map = new mapboxgl.Map({
style: 'mapbox://styles/mapbox/streets-v11',
center: point.center,
zoom: point.zoom,
pitch: point.pitch,
bearing: point.bearing,
container: 'map',
antialias: true,
hash: true
});
map.on('style.load', function() {
if (map.getSource('composite')) {
map.addLayer({
'id': '3d-buildings',
'source': 'composite',
'source-layer': 'building',
'type': 'fill-extrusion',
'minzoom': 14,
'paint': {
'fill-extrusion-color': [
'case',
['boolean', ['feature-state', 'hover'], false],
'#ff0000',
'#ddd'
],
'fill-extrusion-height': ["number", ["get", "height"], 5],
'fill-extrusion-base': ["number", ["get", "min_height"], 0],
'fill-extrusion-opacity': 1
}
}, 'road-label');
}
let fHover;
map.on('mousemove', function(e) {
//157001066
var features = map.queryRenderedFeatures(e.point, {
layers: ['3d-buildings']
});
if (features[0]) {
mouseout();
mouseover(features[0]);
} else {
mouseout();
}
});
map.on('mouseout', function(e) {
mouseout();
});
function mouseout() {
if (!fHover) return;
map.getCanvasContainer().style.cursor = 'default';
map.setFeatureState({
source: fHover.source,
sourceLayer: fHover.sourceLayer,
id: fHover.id
}, {
hover: false
});
}
function mouseover(feature) {
fHover = feature;
map.getCanvasContainer().style.cursor = 'pointer';
map.setFeatureState({
source: fHover.source,
sourceLayer: fHover.sourceLayer,
id: fHover.id
}, {
hover: true
});
}
});

#jscastro This works fine: My requirement is I need to change the color of few buildings with lat and lng. I have achieved getting buildings id's from lat and lng by using below API
https://api.mapbox.com/v4/mapbox.mapbox-streets-v8,mapbox.mapbox-terrain-v2/tilequery/55.26365875255766,25.188400365955193.json?radius=30&limit=10&dedupe&access_token=.
I am facing one issue here, The colors are changing only after zoom level 17. I want to change the color on zoom level 15.

How to hide label in markLine of series-line in Echarts? Or how to change label style?
I tried label: false, not working.
series: [
markLine: {
silent: true,
symbol: false,
label: false,
data: [{
yAxis: 100
}, {
yAxis: 400
}],
lineStyle: {
normal: {
type: "solid",
color: "red"
}
}
}
]
It should be:
series: [
markLine: {
label: {
normal: {
show: false
}
}
}
]
normal is the style when not mouse over or touch down. Otherwise, it would be emphasis.
Please refer to doc.
How to remove sliced line from pie high chart if there there is only one object in data. I want to see complete circle when there is one data coming. Right now it shows one slice line in circle. I don't want it to be there.
plotOptions: {
pie: {
allowPointSelect: true,
slicedOffset: 0
}
},
series: [{
data: [
{
name: 'Firefox',
y: 44.2,
selected: true,
sliced: false
},
]
}]
Screen shot Image
You can do this by setting the borderWidth to 0 and borderColor to null. The default is 1:
plotOptions: {
pie: {
borderWidth: 0,
borderColor: null
}
},
