Changing plot width programmatically.

[Chippy]

I have only been able to find an old reference (2016) to changing the segment width on a plotted line. It was not possible at that time. Is this still the case? I would like to be able to change the plot width in the same way that I can set it's color via Brushes method in OnBarUpdate.

Hello Chippy,

Thanks for your post.

Unfortunately, there are no documented or supported means for changing the width for the segment of a plot. The width could be set for the entire plot, however, not for a specific section of the plot.

That said, this thread will be open for other community members to share their insight on possible undocumented ways to accomplish this.

Let us know if we may assist further.

Thank you Brandon. Alternatively, is line type (dashed, solid, etc) something that can be manipulated by segment on bar update? I can change the color like that. It seems that line style should also be possible to change.

Hello Chippy,

Thanks for your note.

We do not have any supported or documented methods to change the plot style for the segment of a plot. Only the color of a plot could be changed for a specific segment of a plot.

Let us know if we may assist further.

What does the plots.width do then?

Hello Bidder,

Thanks for your note.

Plots[0].Width would change the width of the entire plot.

This would not change the width of the plot for a specific bar or a specific segment only.

For example, the code below would change the entire plot to a width of 5 when the Close[0] > Open[0]. Otherwise, the entire plot would be set to a width of 2.

if (Close[0] > Open[0]
    Plots[0].Width = 5;
else
    Plots[0].Width = 2;

Great. Just what I was looking for. Thanks
