Custom Graphics caching

[rounder8]

Hi,

I'm drawing custom graphics using GDI+ on override void Plot method.

Graphics I'm drawing are quite complex and needs to be updated many times a second. This can cause some computational problems. I need to cache some graphics instead of drawing everything again on every call of Plot method. How can I cache some of the already drawn graphics?

Hello,

Thanks for the note.

The only thing I can think of is changing the chart refresh interval may give you some benefit here.

Right click on the chart->properties->refresh interval by default is half a second. You could lengthen this to a second or greater would probably help you out here with redraw.

Otherwise the chart will plot every half second, you could try using something like a timer or counter to reduce the amount of things you change inside of plot is the only other suggestion I could provide.

Anytime you override plot as I'm sure you are aware you are outside of what is supported NinjaScript so all we can do is offer advice or idea''s if we have them I do not have any samples on how you would do this. Hopefully you find the above useful.
