Sliding series styles shift upon Points.RemoveAt(0)

Question

Hi there, I have a chart series to which a new point is added every second. The symbol is colored using

series.Styles[series.Points.Count-1].Symbol.Color=e.g. red or green. When the series length reaches the display window width in terms of X units, the first point is removed by RemoveAt(0) to prevent the series from growing to infinity. This is good, but the styles shift and suppose every even point was red, now every odd point switches to red from green.

How can I preserve the colors? ( E.g. candles don't change color ).

Hi Gyorgy,Rather than using series. Styles for applying colors, you
can achieve your requirement by utilizing a color palette based on series
points. You can find detailed information and guidance in the respected User

Nitheeshkumar, this seems to solve the problem for one series, but I have more than one and at least one has alternating symbol shapes too (triangle and inverted triangle). Meanwhile I am trying this but it does not work:

private void ShiftSeries( ChartSeries series ) {

series.Points.RemoveAt(0);

for( int i = 0; i < series.Points.Count - 1; i++ )

series.Styles[i].Symbol = series.Styles[i+1].Symbol;

}

Nitheeshkumar, from my side there is no urgency as I solved the problem with system.Charting. For a general audience, pls consider if you want to address it at all. If you do, I am willing to test your solution.

Thanks for your efforts.

Hi Gyorgy,We happy to hear that you can achieve this requirement,
and as discussed this with our development team. The most recommended solution
is to change the symbol based on the segment color, and we have provided the
user guide link below for reference. We will consider this case in the future.
