Hi I am trying really hard to solve this problem. Initially I have an svg-element and inside of it a g-element to make zooming in D3 also possible in Safari. I append a D3 Force-Directed Graph to that g-element after generating it. Zooming works perfectly fine so far.
The Force-Directed Graphis generated as preserved here: https://observablehq.com/#d3/disjoint-force-directed-graph
Initial svg-element created:
svg.value = d3
.select("#network")
.append("svg")
.attr("width", width)
.attr("height", height)
.attr("viewBox", [0, 0, width, height])
.append("g");
Adding the chart:
d3.select("#network").selectAll("svg g > *").remove();
d3.select("#network").select("svg g").node().append(chart);
And the zoom-function afterwards:
const svgZoom = d3.select("#network svg");
const g = d3.select("#network svg g");
svgZoom.call(
d3
.zoom()
.on("zoom", function () {
g.attr("transform", d3.zoomTransform(this));
})
);
Now the issue is that the graph always gets cut. I already tried visibility:visible on each of those elements, still not working. Even if I set a viewBox much bigger than the actual content, or if I set the size of the graph to a minimum, the graph will always get cut to a rectangle.
What I want to accomplish is add the graph full-size and by zooming out the overflowing elements get visible. I do not want to get the height and width of the container and minimize the size of each graph drawn, because some graphs are much bigger than the other ones and I want to keep the initial size of the nodes.
How it currenty looks

Zooming Out
The graph itself cuts the boundaries, adding overflow:visible to the Force-Directed Graph solved the problem.

I am new to d3v4 and working on a chart where i need to show little rectangle on certain date matching to its title on yaxis. The problem i am facing is rectangles in the chart area not drawing equal to the yaxis point labels, i have tried changing the y value by hardcoding, it works fine but the point is the number of data object will change in real time like it could be any number of objects in an array. Here is the plunker
To draw the graph dynamically with limited data objects i've created few buttons on top of chart so that rectangles in the chart can draw equal to y-axis labels.
Any help is much appreciated.
You are using a band scale: that being the case, you should not change the y position, which should be just...
.attr('y', function(d) {
return yScale(d.title);
})
.. and you should not hardcode the height: use the bandwidth() instead:
.attr('height', yScale.bandwidth())
The issue now is setting the paddingInner and paddingOuter of the scale until you have the desired result. For instance:
var yScale = d3.scaleBand().domain(data.map(function(d) {
return d.title
}))
.range([height - 20, 0])
.paddingInner(0.75)
.paddingOuter(.2);
Here is the plunker with those changes: https://plnkr.co/edit/ZxGCeDGYwDGzUCYiSztQ?p=preview
However, if you still want (for whatever reason) hardcode the height or the width of the rectangles, use a point scale instead, and move the y position by half the height.
I use jquery and d3.js to draw a chart inside a message dialog.
How can I resize the d3.js chart without redrawing the entire chart?
The current solution works but is really inefficient: http://jsfiddle.net/L6UGn/61/ I did not figure out how to update the width, height without redrawing the entire chart.
My idea was update the width and height of the svg. Any idea how to approach it?
d3.select('#msg_dialog > svg') //.selectAll("g")
.attr('width', width)
.attr('height', height);
I tried http://bl.ocks.org/godds/ec089a2cf3e06a2cd5fc
However, I found when I used the brush, the main part of the stacked bar is out of boundary. How to fix it?
I think here is the reason:
some bars should not be shown in the main part but they are still in the scope of svg
Thank you for your help!
These types of zoom literally are just geometric zooms, all the bars are still being drawn, it's just that the vast majority are off-screen, some are within the chart limits and a few lie in the axis gap in-between which are the ones that look awkward.
Make a svg clip, and add it to the right 'g' element to get rid of this effect:
svg.append("defs").append("clipPath")
.attr("id", "myclip")
.append ("rect")
.attr({x: 0, width: width, y: margin.top, height: height});
... and later on in the code
// draw the bars
main.append("g")
.attr("clip-path", "url(#myclip)")
.attr("class", "bars")
I'm learning how to plot charts using D3.js on SVG objects.
My code creates elements in DOM objects, but they do not display.
If I run DOM inspector and copy all elements to another html document and display that the rectangles are visible.
I'm trying to plot two static rectangles on JSFiddle
SVG is case sensitive so you want
svg = d3.select("div#Wykres2")
.append("svg")
.attr("width", szerokosc)
.attr("height", wysokosc)
.text("not work :(");
I have set up a clip path on a D3.js zoomable focus and context graph, but have a slight problem. http://nestoria.darkgreener.com/v2/
The clip path is cutting off some circles from the edge of the focus graph - you'll see that the top and right-hand circles are only half there!
It works well on zoom, though, as you'll see if you click and drag the context graph.
So I'm not sure how to create a clip path that doesn't cut off the edges of these circles. This is my code:
focus.append("defs")
.append("clipPath")
.attr("id", "clip")
.append("rect")
.attr("width", width - 200)
.attr("height", height);
var focus_dots = focus
.selectAll(".dot")
.data(mydata[j].data);
focus_dots.enter()
.append("circle")
.attr("clip-path", "url(#clip)");
Any ideas? Your help would be very much appreciated as I'm completely baffled about what to do here!
If you don't want the clipping to not be applied when hovering you can use a stylerule like this:
circle:hover { clip-path: none; }
I had the same problem and got around it using
.attr("transform", "translate(0,-20)")
.attr("height", height+20)
The Idea is a bit hacky, but if you simply move the clipping window up and add the same amount to its height, it should show (in the above case) 20px more on top. (same for left side; concerning the right and bottom side: simply add some pixels to hight/width).
I've used "transform",and the circles were cut to quarter.So use cx and cy instead, problem solved..
