    Hi.

    Is there any solution to avoid heaviest redraw and flickering during form resize operations in cases when charting control placed on form?
    I noticed this strange behaviour only on chart control.  Issues easily reproduced on your demo sample (zoom.zip). Launch it and try to resize form with mouse. 
    You can notice here not painted background appears on new form rectangle till the moment when chart drawn. This is very noticeable even if to use core i7 with 32Gb ram and video card with 1gb ram, and that effect had very bad impact on presentation charts when intensive using it. 

    I hope that there is some solution to avoid that behaviour. Please help to find solution. 
    Thank you in advance. 
    Alex.

    Hello Alex,

    We have recently introduced new types of rendering options. You can take a look at our online documentation and read the topic about the different rendering types we now support. The performance of the chart is better in Direct2D rendering and Bitmap rendering types. Please give this approach a try.

    Hope it helps.
