I created a responsive rect as an artboard in the stage, and when I add shapes and move them, I want the shapes to only show on the rect, just like opening a window on the stage, only show the shapes inside the window
You should use clipping for that. Tutorial: https://konvajs.org/docs/clipping/Clipping_Regions.html
import React from "react";
import { createRoot } from "react-dom/client";
import { Stage, Layer, Star } from "react-konva";
function generateShapes() {
return [...Array(50)].map((_, i) => ({
id: i.toString(),
x: Math.random() * window.innerWidth,
y: Math.random() * window.innerHeight,
rotation: Math.random() * 180,
isDragging: false
}));
}
const INITIAL_STATE = generateShapes();
const STAR_PROPS = {
numPoints: 5,
innerRadius: 20,
outerRadius: 40,
fill: "#89b717",
opacity: 0.8,
shadowColorL: "black",
shadowBlur: 10,
shadowOpacity: 0.6,
shadowOffsetX: 5,
shadowOffsetY: 5,
scaleX: 1,
scaleY: 1,
draggable: true
};
const App = () => {
const [stars] = React.useState(INITIAL_STATE);
return (
<Stage width={window.innerWidth} height={window.innerHeight}>
<Layer
clipX={50}
clipY={50}
clipWidth={window.innerWidth - 100}
clipHeight={window.innerWidth - 100}
>
{stars.map((star) => (
<Star
{...STAR_PROPS}
key={star.id}
id={star.id}
x={star.x}
y={star.y}
rotation={star.rotation}
/>
))}
</Layer>
</Stage>
);
};
const container = document.getElementById("root");
const root = createRoot(container);
root.render(<App />);

I'm creating a timeline with Konva and the entire timeline (stage) is draggable on all directions but I have an axis with all the years of the timeline (Konva group) that I want to restrict its movement so that it only moves horizontally.
I can't use dragBoundFunc as it will restrict the movement on all nodes of the timeline.
I tried to change the position of the element using the dragmove event:
stage.on("dragmove", function(evt) {
xaxis.y(0);
});
But the xaxis still moves on all direction while dragging the stage.
I could also use different draggable layers for the axis and the timeline itself, but then when I drag the axis it wouldn't move the timeline and the same if I move the timeline.
As the simplest solution, you can just make sure that the absolute position of your timelime group is the same:
stage.on("dragmove", function(evt) {
// read absolute position
const oldAbs = xaxis.absolutePosition();
// set new absolute position, but make sure x = 0
xaxis.absolutePosition({
x: oldAbs.x,
y: 0
});
});
Here is a slightly more capable version that allows vertical drag of the event layer whilst keeping the time line axis visible for reference. This uses two layers - one to act as the background containing the time line and grid, whilst the second shows the events.
The key technique here is using the dragMove event listener on the draggable event layer to move the background layer in sync horizontally but NOT vertically. Meanwhile the event layer is also constrained with a dragBound function to stop silly UX.
An improvement would be to add clipping to the event layer so that when dragged down it would not obscure the timeline.

It is not entirely clear what you are asking but I have assumed you want to constrain the drag of the timeline so that it gives good UX. See working snippet below. The majority of the code is setup of the timeline. The important piece is
Include a rect covering the entire timeline that has zero opacity and is listening for mouse events.
Provide the layer with a dragBoundFunc that returns an object as {x: val, y: val} in which the x is constricted to stop the user dragging out of sight horizontally, and the y is not allowed to change. If you think of the rect and the stage as rectangles then the math is not difficult to comprehend. If your timeline is vertical, swap the x & y behaviour.
var stageWidth = 800,
timeFrom = 1960,
timeTo = 2060,
range = timeTo - timeFrom,
timeLineWidth = 1000;
yearWidth = timeLineWidth / range,

<div id="container"></div>
I would like to highlight the fact that there is a container for Rickinaaa and Anneinaaa, with a description.
Right now Rickinaaa and Anneinaaa are at the same level as Anne and Peter, despite the fact that it is their container (the one I do not know how to show) which should be at their level.
An example from ZingCharts which shows this multilayer presentation:
It is much easier to see the box-in-a-box structure.
Is there a way to achieve this in Highcharts? Specifically, how could I have a visible container labelled aaa container which would encompass the rectangles Rickinaaa and Anneinaaa
It can be done by using custom positioning algorithm for treemap. The process is described here: https://www.highcharts.com/docs/chart-and-series-types/treemap (ADD YOUR OWN ALGORITHM section).
I created simplified algorithm for demo purposes (some values are hardcoded):
// Custom positioning algorithm
function myFunction(parent, children) {
childrenAreas = [];
Highcharts.each(children, function(child) {
// Do some calculations
var newLeaf = null;
if (child.id === 'A') {
newLeaf = {
x: 0,
y: 0,
width: 50,
height: 50
};
} else if (child.id === 'B') {
newLeaf = {
x: 50,
y: 0,
width: 50,
height: 50
};
} else if (child.name === 'Rick') {
newLeaf = {
x: parent.x + 10,
y: parent.y + 10,
width: parent.width - 20,
height: (parent.height - 20) / 2
}
} else if (child.name === 'Peter') {
newLeaf = {
x: parent.x + 10,
y: parent.y + 30,
width: parent.width - 20,
height: (parent.height - 20) / 2
}
} else if (child.name === 'Anne') {
newLeaf = {
x: parent.x + 10,
y: 10,
width: parent.width - 20,
height: parent.height - 20
}
}
if (newLeaf) {
childrenAreas.push(newLeaf);
}
});
return childrenAreas;
};
Highcharts.seriesTypes.treemap.prototype.myCustomAlgorithm = myFunction;
By default Highcharts assigns color fill attribute only for the nodes of the Highest level - all other nodes have it set to none. It can be changed manually via CSS:
.highcharts-internal-node {
fill: #bada55
}
I also did a small change in the core code so that parent levels are drawn underneath the child ones:
(function(H) {
var grep = H.grep,
each = H.each,
seriesTypes = H.seriesTypes;
H.seriesTypes.treemap.prototype.drawPoints = function() {
var series = this,
points = grep(series.points, function(n) {
return n.node.visible;
});
each(points, function(point) {
var groupKey = 'level-group-' + point.node.levelDynamic;
if (!series[groupKey]) {
series[groupKey] = series.chart.renderer.g(groupKey)
.attr({
// CHANGED FROM: zIndex: 1000 - point.node.levelDynamic
zIndex: 1000 + point.node.levelDynamic // #todo Set the zIndex based upon the number of levels, instead of using 1000
})
.add(series.group);
}
point.group = series[groupKey];
});
// Call standard drawPoints
seriesTypes.column.prototype.drawPoints.call(this);
// If drillToNode is allowed, set a point cursor on clickables & add drillId to point
if (series.options.allowDrillToNode) {
each(points, function(point) {
if (point.graphic) {
point.drillId = series.options.interactByLeaf ? series.drillToByLeaf(point) : series.drillToByGroup(point);
}
});
}
}
})(Highcharts);

I just check a post regarding making a label with design using renderer.label and plotline animate (Add design to plotLabel Highcharts). My question is, Is there a way to use chart.renderer.path as the moving horizontal gridline instead of using the common plotline ? I am a bit confuse on how to use the renderer.path. Can you help me with it? Really appreciate your help with this.
const plotband = yAxis.addPlotLine({
value: 66,
color: 'red',
width: 2,
id: 'plot-line-1',
/* label: {
text: 66,
align: 'right',
y: newY,
x: 0
}*/
});
const labelOffset = 15
const plotbandLabel = this.renderer.label((66).toFixed(2), chart.plotLeft + chart.plotWidth - 8, yAxis.toPixels(66) - labelOffset, 'rect').css({
color: '#FFFFFF'
}).attr({
align: 'right',
zIndex: 99,
fill: 'rgba(0, 0, 0, 0.75)',
padding: 8
})
.add()
setInterval(function() {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 100);
series.addPoint([x, y], true, true);
plotLine = yAxis.plotLinesAndBands[0].svgElem;
d = plotLine.d.split(' ');
newY = yAxis.toPixels(y) - d[2];
plotlabel = yAxis.plotLinesAndBands[0].label;
plotbandLabel.animate({
y: yAxis.toPixels(y) - labelOffset
}, {
duration: 400,
step: function() {
this.attr({
text: yAxis.toValue(this.y + labelOffset).toFixed(2)
})
},
complete: function() {
this.attr({
text: y.toFixed(2)
})
}
}),
plotLine.animate({
translateY: newY
}, 400);
Please see this jsfiddle I got from the previous post. http://jsfiddle.net/x8vhp0gr/
Thank you so much
I modified demo provided by you. Now, instead of adding a plot line, path is created.
pathLine = this.renderer.path([
'M',
chart.plotLeft,
initialValue,
'L',
chart.plotWidth + chart.plotLeft,
initialValue
])
.attr({
'stroke-width': 2,
stroke: 'red'
})
.add(svgGroup);

double click on square shape, you can resize it now.
double click on circle shape, its still resizing square shape.
Can you please let me know how to fix this issue that no matter which shape is double clicked, square is getting resized.
I think that right now you have problem with getting right annotation in your chart. You are getting always the same rect shape because you are using fixed:
annotation = annotations[annotations.length - 1];
Instead this line, you can set your annotation object inside Highcharts.each:
var each = Highcharts.each;
each(chart.annotations.allItems, function(item, i) {
if (item.selectionMarker) {
annotation = item;
shape = item.shape.element.localName;
}
});
Here you can see an example how it can work:
