Create a chart on a background thread

Post by ezray3 » Sun Nov 11, 2018 9:48 am

Hi,

In my application I have a feature that the user can export data,
I want to add an image of a chart to that export.

I tried to use "SaveToStream" which returned "false" and did nothing.
If I understand correctly, the chart must be rendered in order to save it to a stream?

I specifically interested in heat map conversion.
How can I achieve this using LightningChart: Converting my data to heat map and save it to stream. All of this on a background thread?
Is it possible at all?

Thanks!

In typical usage, chart should be rendered before using most of it functions.
However, LightningChart also has Headless Rendering feature. That is, Headless configuration allows running LightningChart in a headless/server environment. Expected scenarios include background rendering in software applications without User Interface (UI) and generation of a bitmap image from the chart content.
For more details, please check our User's Manual (http://www.arction.com -> Docs) chapter 21. Headless mode and corresponding Demo example.

Hope this helps.
