Plotly.js with Angular how to automatically resize choropleth [duplicate]

I'm trying to make a choropleth map, but how can I set the size of the map?
Now I've this map:
I would like expand the map to all the space, I read the documentations but I didn't find a solution.
This is my code:
var data = [{
type: 'choropleth',
locationmode: 'country names',
locations: unpack(output, 'label'),
z: unpack(output, 'nres'),
text: unpack(output, 'nres')
}];
var layout = {
geo: {
projection: {
type: 'equirectangular'
}
}
};
Plotly.plot(mapChoropleth, data, layout, {
showLink: false
});

Plotly tries to take all the available space without changing the image ratio. If you have a very wide div there will be a lot of empty space to left and right due but it will be filled from the top to the bottom.
You could change height and width in layout, change the margins and fine tune the color bar to get the desired result.
Plotly.d3.csv('https://raw.githubusercontent.com/plotly/datasets/master/2014_world_gdp_with_codes.csv', function(err, rows) {
function unpack(rows, key) {
return rows.map(function(row) {
return row[key];
});
}
var data = [{
type: 'choropleth',
locations: unpack(rows, 'CODE'),
z: unpack(rows, 'GDP (BILLIONS)'),
text: unpack(rows, 'COUNTRY'),

};
Plotly.plot(myDiv, data, layout, {
showLink: false
});
});
<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
<div id="myDiv"></div>
You can also change the ratio of the map directly, an ugly but working possibility.
var c = document.getElementsByClassName('countries')[0];
c.setAttribute('transform', 'translate(-300), scale(3, 1)');
c = document.getElementsByClassName('choropleth')[0];
c.setAttribute('transform', 'translate(-300), scale(3, 1)');
c = document.getElementsByClassName('clips')[0].firstChild.firstChild;
c.setAttribute('x', -300);
c.setAttribute('width', 900);
The map is first drawn normally and then resized when clicked on.

var data = [];

Can ports be changed from circle to rectangle?

I am working with JointJS ports. By default ports are displayed as circles:
https://resources.jointjs.com/tutorial/ports
Is there any way to format the style from circle to rectangle? Please suggest any class names where I can override this.

the tutorial there is using the devs.Model shapes and it's a bit outdated approach...
There is a markup option in the port configuration, see more at https://resources.jointjs.com/docs/jointjs/v2.1/joint.html#dia.Element.ports
I'd recommend a port demo (https://github.com/clientIO/joint/tree/master/demo/ports). There is even a shape you're might be looking for:
var g6 = new joint.shapes.basic.Circle({
position: { x: 50, y: 50 },
size: { width: 500, height: 300 },
attrs: {
text: { text: 'compensateRotation: true', fill: '#6a6c8a' },
circle: { stroke: '#31d0c6', 'stroke-width': 2 }
},
ports: {
groups: {
'a': {
position: {
name: 'ellipseSpread',
args: { startAngle: 0, dr: 0, compensateRotation: true }
},
label: {
position: 'radial'
},
attrs: {
rect: {
stroke: '#31d0c6',
'stroke-width': 2,
width: 20,
height: 20,
x: -10,
y: -10
},
'.dot': {
fill: '#fe854f',
r: 2
},
text: {
fill: '#6a6c8a'
}
},
markup: '<g><rect/><circle class="dot"/></g>'
}
}
}
});

I have a chart in a tab that's by default hidden. When a user clicks on that tab, they appear. However, they're skewed a bit, smooshed horizontally and stretched vertically. See the Fiddle for what I mean, it's under "tab 2".
Changing the browser's zoom level (in Firefox at least) seems to make it correct itself.
I noticed if I put it inside tab 1, however, on page load it displays correctly. It's only when it's not the default tab does it warp around and requires zoom change to display correctly.
What's going on here? It looks like the graph is only rendered when I open the tab (judging by the animation). I was thinking maybe it's because of the display property in CSS but maybe it's because it needs to be rendered at page load?
Here's an editable fiddle:
http://jsfiddle.net/ryfy8j9s/1/

The problem is that the chart's default width is set to 500, and even though you are calling chart.render() in window.onload, since its container is not visible it creates the chart at the default width and it's stuck there until chart.render() is called again (e.g., for a window resize). This isn't the only issue. For example, if you resize the window to fix the chart, but then click back on tab1, resize the window again, and click back to tab2, once again the chart is the wrong size.
You could set an explicit width when the chart is created, but that would make the chart non-responsive to resize, which probably isn't what you want.
I would suggest a click handler on tab2 to check for this exact situation and call chart.render() only if the chart is visible and not the same size as its container:
window.onload = function () {
$("#cp_tab2").on("click", function() {
if ($("#chartContainer").is(":visible") && $("#chartContainer canvas").width() !== $("#chartContainer").width()) {
chart.render();
}
});
var chart = new CanvasJS.Chart("chartContainer", {
zoomEnabled: false,
// etc.
I tried this on your fiddle and it fixes the issue. See my fork of your jsFiddle. with this working.

Possible solution is to call resize method on window just after the load of graph , i managed to correct it like that
$(window).resize();

Dynamically Add Data Points To Rickshaw Graph

So I'm using the Rickshaw graphing library and I was wondering how to dynamically add points to a graph.
I have a graph instantiated like this:
#seriesData = [ [], [], [] ]
random = new Rickshaw.Fixtures.RandomData(150)
for (var i = 0; i < 50; i++) {
random.addData(self.seriesData)
}
#graph = new Rickshaw.Graph(
element: document.getElementById("chart")
width: 550
height: 300
renderer: 'area'
series: [
{
color: "#c05020"
data: self.seriesData[0]
name: 'One'
}, {
color: "#30c020"
data: self.seriesData[1]
name: 'Two'
}, {
color: "#2791d7"
data: self.seriesData[2]
name: 'Three'
}
]
)
#graph.render()
hoverDetail = new Rickshaw.Graph.HoverDetail(
graph: self.graph
)
legend = new Rickshaw.Graph.Legend(
graph: self.graph
element: document.getElementById('legend')
)
shelving = new Rickshaw.Graph.Behavior.Series.Toggle(
graph: self.graph
legend: legend
)
axes = new Rickshaw.Graph.Axis.Time(
graph: self.graph
)
axes.render()
And I have data coming in through socket.io like this:
app.on('data',
(one, two, three) =>
// Dynamically add data points to graph
)
And I was wondering how to append these three points to the graph. I can't find any good documentation for this library. I know it's built on top of d3.js, but I'm not sure how to incorporate these methods into my graph.
Any help would be appreciated.

I envision two scenario that could solve your question:
Using the fixed Window Series for Streaming Data
leveraging the fact that arrays in javascript are passed by reference. A demo is available here
.
var data = [
{
data: [ { x: 0, y: 120 }, { x: 1, y: 890 }, { x: 2, y: 38 }, { x: 3, y: 70 }, { x: 4, y: 32 } ],
color: "#c05020"
}, {
data: [ { x: 0, y: 80 }, { x: 1, y: 200 }, { x: 2, y: 100 }, { x: 3, y: 520 }, { x: 4, y: 133 } ],
color: "#30c020"
}
];
var graph = new Rickshaw.Graph( {
element: document.getElementById("chart"),
renderer: 'line',
height: 300,
width: 800,
series: data
} );
var y_ticks = new Rickshaw.Graph.Axis.Y( {
graph: graph,
orientation: 'left',
tickFormat: Rickshaw.Fixtures.Number.formatKMBT,
element: document.getElementById('y_axis'),
} );
graph.render();
$('button#add').click(function() {
data.push({
data: [ { x: 0, y: 200 }, { x: 1, y: 390 }, { x: 2, y: 1000 }, { x: 3, y: 200 }, { x: 4, y: 230 } ],
color: "#6060c0"
});
graph.update();
});

Adding data to empty rickshaw chart

I am charting different data with RickshawJS. But I need a way to update the chart when a user clicks the #search button. Right now it just creates a new chart below the old one, and that is pretty messy.
The user enters the page and enters some details and clicks the button to chart it. So ideally I'd like to start with an empty chart that isn't shown, but I can't really figure out how to remove the data from the chart and axes and then update it.
I could call $('#chart svg').remove(); on the chart and axes but it seems messy.
$('#search').click(function(event){
event.preventDefault();
var data = utils.malletData();
var graph = new Rickshaw.Graph( {
element: document.querySelector("#chart"),
width: 800,
height: 250,
series: [ {
name: data['name'],
color: 'steelblue',
data: data['series']
} ]
} );
graph.render();
var hoverDetail = new Rickshaw.Graph.HoverDetail( {
graph: graph,
xFormatter: function(x) {
var date = new Date(x).getTime();
return moment(x).format('MMMM Do YYYY, h:mm:ss a');
},
yFormatter: function(y) { return Math.floor(y) + " users" }
} );
var xAxis = new Rickshaw.Graph.Axis.X( {
graph: graph,
orientation: 'bottom',
element: document.getElementById('x_axis'),
tickFormat: function(x) { return moment(x).fromNow(); },
ticks: 7,
tickSize: 1,
} );
xAxis.render();
var ticksTreatment = 'glow';
var yAxis = new Rickshaw.Graph.Axis.Y( {
graph: graph,
orientation: 'left',
tickFormat: Rickshaw.Fixtures.Number.formatKMBT,
ticksTreatment: ticksTreatment,
element: document.getElementById('y_axis'),
} );
yAxis.render();
});

There's no official way to do so. However, you could leverage the fact that arrays in javascript are passed by reference and then update the graph.
