yAxis resizer to change svgrenderer position also highcharts - highcharts

Question

I have a chart with some indicators below it. Each indicator area consists
of a svg renderer button. so when I use resize property to drag and resize
the panes, the series resized perfectly but the button remains in its same
position, Can we move the button with the resizer?
Here I created a sample link to regenerate

Any help will be appreciated. I am having great trouble. Thank you

Answer 1

You can add and position the custom button in render event:
chart: {
events: {
render: function() {
var chart = this;
if (chart.customBtn) {
chart.customBtn.attr({
y: chart.yAxis[1].top,
});
} else {
chart.customBtn = chart.renderer.button(
'sometext',
5,
chart.yAxis[1].top,
function() {
console.log('some task')
}).add()
}
}
}
},

I was able to do something by manually changing the x/y attributes of my svgRenderer label, the same should apply to buttons.
I'm in angular and have a listener for screen resizing:
Also Note that you can change the entire SVGRenderer label with the attr.text property.
this.chart = Highcharts.chart(.....);
// I used a helper method to create the label
this.chart.myLabel = this.labelCreationHelperMethod(this.chart, data);
this.windowEventService.resize$.subscribe(dimensions => {
if(dimensions.x < 500) { //this would be your charts resize breakpoint
// here I was using a specific chart series property to tell where to put my x coordinate,
// you can traverse through the chart object to find a similar number,
// or just use a hardcoded number
this.chart.myLabel.attr({ y: 15, x: this.chart.series[0].points[0].plotX + 20 });
} else {
this.chart.myLabel.attr({ y: 100, x: this.chart.series[0].points[0].plotX + 50 });
}
}
//Returns the label object that we keep a reference to in the chart object.
labelCreationHelperMethod() {
const y = screen.width > 500 ? 100 : 15; 
const x = screen.width > 500 ? this.chart.series[0].points[0].plotX + 50 :
this.chart.series[0].points[0].plotX + 20
// your label
const label = `<div style="color: blue"...> My Label Stuff</div>`
return chart.renderer.label(label, x, y, 'callout', offset + chart.plotLeft, chart.plotTop + 80, true)
.attr({
fill: '#e8e8e8',
padding: 15,
r: 5,
zIndex: 6
})
.add();
}
