I have been using Material ui themes for styled components in React. Now, We have a requirement in our application to use highcharts. But I still wanted to retain the same themeing for highcharts as well. Is there a way we could integrate Material UI theme to style highcharts chart? I did google this a lot before finally deciding to raise the question here. I know that highcharts provide their own theme. But I do not want to make the code messier with multiple themes. Is there a way to achieve this in a cleaner way? Any help would be much appreciated. Thanks in advance!
Highcharts have a possibility to set themes by Highcharts.setOptions to create schemate fit to you. That you can see there are specific sets for charts elements for that material UI it's not changing charts looks.

// set the theme

I use konva.js and I try to align texts with the align function but I can't do it with the left alignment (right and center works on the other hand)
my code
var text1 = new Konva.Text({
y: 26,
fontSize: 40,
text: 'ligne1',
draggable: true,
width : 550,
align: 'center',
});
layer.add(text1);
layer.draw();
Thank you
The text.align() method sets the alignment. In the snippet below I have drawn a rect around the text shape to give a visualisation of the effect.
let
// Set up a stage
stage = new Konva.Stage({
container: 'container',
width: window.innerWidth,
height: window.innerHeight
}),
layer = new Konva.Layer(),
rect = new Konva.Rect({
x: 0,
y: 26,
width: 550,
height: 40,
stroke: 'magenta'
}),
text1 = new Konva.Text({
y: 26,
fontSize: 40,
text: 'ligne1',
draggable: true,
width: 550,
align: 'center',
fill: 'cyan'
});
stage.add(layer);
layer.add(rect, text1);
layer.draw();
$('#left').on('click', function() {
text1.align('left');
layer.draw();
})
$('#center').on('click', function() {
text1.align('center');
layer.draw();
})
$('#right').on('click', function() {
text1.align('right');
layer.draw();
})

In my mapping application, I can hightlight the polygon, when mouseover it or select it, but the point and lineString cannot be highlighted, thought I add the style in script.
I found some working examples with ol.featureOverlay online, but now in new openlayers3, ol.featureOverlay is removed from library, do some specialists know how to solve it?
Tell your interaction to read the styles from a function of yours:
var hoverInteraction = new ol.interaction.Select({
condition: ol.events.condition.pointerMove,
style: geometryStyle
});
And your function will be like above:
function geometryStyle(feature){
var
style = [],
geometry_type = feature.getGeometry().getType(),
white = [255, 255, 255, 1],
blue = [0, 153, 255, 1],
width = 6
;
style['LineString'] = [
new ol.style.Style({
stroke: new ol.style.Stroke({
color: white, width: width + 2
})
}),
new ol.style.Style({
stroke: new ol.style.Stroke({
color: blue, width: width
})
})
],
style['Polygon'] = [
new ol.style.Style({
fill: new ol.style.Fill({ color: [255, 255, 255, 0.5] })
}),
new ol.style.Style({
stroke: new ol.style.Stroke({
color: white, width: 3.5
})
}),
new ol.style.Style({
stroke: new ol.style.Stroke({
color: blue, width: 2.5
})
})
],
style['Point'] = [
new ol.style.Style({
image: new ol.style.Circle({
radius: width * 2,
fill: new ol.style.Fill({color: blue}),
stroke: new ol.style.Stroke({
color: white, width: width / 2
})
})
})
];
return style[geometry_type];
}

I am trying to plot the map of Latin American countries using openlayers 3 in my asp.net mvc app.
I have geojsonobject of the countries and I tried the below code but map is not displayed..
My requirements is to only show LAC with interaction and different color filling of the different countries.

Polygon not plotted for bolivia please help...
Projection/CRS
Your GeoJSON specifies using EPSG:3857 (crs: {'type':'name','properties':{'name':'EPSG:3857'}}), but your coordinates does not seem to be in EPSG:3857. EPSG:3857's units is meters, and coordinates such as [-62.846468,-22.034985] are less than 100 meters from the equator and the Greenwich meridian.
Your coordinates are probably in EPSG:4326 (latitude and longitude in degrees). If that's true, change the GeoJSON to reflect that (set crs: {'type':'name','properties':{'name':'EPSG:4326'}}.
With features in EPSG:4326, you also have to change the view projection to EPSG:4326 or reproject the features to EPSG:3857. EPSG:3857 is normally used for global web mapping applications.
In order to read GeoJSON in EPSG:4326 and get features in EPSG:3857, change
(new ol.format.GeoJSON()).readFeatures(geojsonObject)
to
(new ol.format.GeoJSON()).readFeatures(geojsonObject,
{'featureProjection': ol.proj.get('EPSG:3857')})
Initial center
The inital center of the map does not seem to be focused on your data. You could insert this after the map is initialized:
map.getView().fit(source.getExtent(), map.getSize())
