drawings on barupdate superimposed with those from onrender

[RubenCazorla]

Hello again, I have a problem since I am making an indicator that on the one hand draws when certain conditions are met in onbarupdate, normal drawings, text lines and rectangles, and in onrender later, when I select certain text-only drawings, it appears the most detailed information of that text using RenderTarget.FillRectangle(lineRect, currentBackgroundBrush2); and RenderTarget.DrawTextLayout(new SharpDX.Vector2(textLeft, textTop), textLayoutLine, textBrushDX2); The problem is that when I move through the graph, the onbarupdate drawings are mixed as if it had no opacity in on render and it has it at 100%


The first problem is more critical, the second I have browsed the forum and it seems to have no solution at least for now, and it seems that they are collecting votes to change it, when drawing onrender I sometimes get a text that is too long, I solve it with this ;

private void ChartControl_MouseWheel(object sender, System.Windows.Input.MouseWheelEventArgs e)
{
scrollOffsetY -= e.Delta * scrollStep / 120.0f; // e.Delta es normalmente un múltiplo de 120

// Limitar el desplazamiento mínimo y máximo según el tamaño del contenido
scrollOffsetY = Math.Max(scrollOffsetY, 0); // No permitir desplazamiento negativo
// Puedes añadir una restricción máxima basada en el tamaño del contenido si es necesario

// Redibujar el gráfico
ChartControl.InvalidateVisual();
}


It works perfectly but it also moves the background graphic, I would like that while the drawing is active the graphic does not move horizontally, but I can't do it.

thank you very much again

Hello RubenCazorla,

Preventing the intended behavior of the scrollwheel from adjusting the chart horizontal axis (time scale) range would not be supported by NinjaTrader.
Unfortunately, I am not aware of any unsupported resources I can provide on this topic.

Possibly setting the .Handled property to true may have an effect, but I would not be certain.
((HandledMouseEventArgs)e).Handled = true;

This thread will remain open for any community members that would like to share unsupported suggestions.
