Getting the edges of Geojson chart

[Jiren]

How can I get the coordinates of these red points (look at the screenshot)?

Thanks for contacting us with your question!

It depends on what you need those coordinates for. The easiest way is to show how to draw rectangles on both the corners of the chart. I did that using Highcharts.SVGRenderer.

The first argument when drawing the rectangle is the x coordinate and the second one is y. If you want to place something in the top right corner, check the coordinates of the first rect drawn, basically, it's based on the chart.chartWidth and for the bottom left corner we need chart.chartHeight as in the second rectangle.

Let me know if that was what you were looking for!

No, this isn't what I'm looking for:

I'm not looking for the borders of the chart, I'm looking for the borders of my object.
As you can see, I can get the bottom left one (because it has the coordinates of 0;0), but I don't understand how to get the top right.

Hey!

There is no direct way to find out the exact coordinates of the corners, but we have a demo with built in functionality, so that the lon/lat are displayed on mouse move. You can apply this logic in your chart and check your desired coordinates.

I hope you will find it useful
