OnRender drawline

[luxurious_04]

Can someone help me on converting this to NT8?

Point[][] linePoints = new Point[flines][];

for (i = 0; i <flines; i++)
graphics.DrawLines(linePrices[i].Pen, linePoints[i]);

It would result a continuous line.

Hello luxurious_04,

Thank you for the post.

You will need to use SharpDX in NinjaTrader 8. For an example on how to render lines in OnRender, have a look at the "SampleCustomRender" indicator. That script demonstrates how to use SharpDX in the context of a NinjaScript, notice how the line is drawn with RenderTarget.DrawLine(...).

Here is the help guide page on using SharpDX for custom plotting:

Please let me know if I can assist further.

Ok I have check that already my problem how can I convert Points[][] linePoints or what is the equivalent of linePoints[i] in OnRender.Drawline? In OnRender.Drawline it needs to vector points while in graphics.Drawlines in NT7 it only use points of array like linePoints[i].

Hello luxurious_04,

Thank you for the reply.

The DrawLines method takes two Points. This is the equivalent of the Point array to draw.

Below is a public link to three examples of how to use DrawLine
