Questions about Highcharts

Hello,

I am interested in Highcharts, but I have these 9 questions.

1. Can the charts support real time changing of the X and Y axis labels/coordinates.
2. Can the charts support adding comments.
3. Do they have a chart that supports ‘stacking’.
4. Do the charts support drilling down.
5. Can there be multiple instances of highchart charts on a single page? For example, a line chart, bar chart and scatter
6. Does highcharts support plugins, or the ability to add new custom features/code
7. Does high charts get upgrades? And if so, is there anything that the developer needs to be aware of if they adding code that is dependent on highcharts objects?
8. Does highcharts support responsive design
9. Does high charts have any functions that support ajax calls?

Thank you in advanced!

1. Yes, you can zoom and pan manually or by code. There is also Axis.update that can be used to change X and Y axis labels in real time. As a last resource there is always an option to just rebuild a chart.

Re: Questions about Highcharts

Hi Nitish,
Welcome to our forum and thanks for contacting us with your question!

There isn't such functionality to divide point into the section at our API, the best way to achieve your goal will be to draw elements by SVG.
For example, for the drawing bar, I found the width of the first point and I drew rect by SVG renderer.

Live demo:
https://jsfiddle.net/BlackLabel/ptoLr96q/

API References:
https://api.highcharts.com/class-refere ... VGRenderer

Let me know how are you doing with this.
Best regards.

Re: Questions about Highcharts

Hi,
Thanks for your question and welcome to our forum.

The whole chart is rendered the only option would be to render such a bar.
Next anchoring it in a fixed location, the chart renders on the fly and you would have to recalculate its position each time.

Can you share your code in a simplified version? I'd like to see what your case looks like.

I look forward to hearing from you,
Best regards.

Hi,
Thanks for your fiddle,

I only presented you with a concept, this task is too time-consuming for me to undertake in support.
