ninjascript to change chart background color

[llanqui]

I am getting a compile error...

'NinjaTrader.Gui.Chart.ChartControl' does not contain a definition for 'ChartBackground' and no extension method 'ChartBackground' accepting a first argument of type 'NinjaTrader.Gui.Chart.ChartControl' could be found (are you missing a using directive or an assembly reference?)

with this statement

ChartControl.ChartBackground = Brushes.Gold;

(ChartBackground is a documented property of ChartControl)

i have this using

using NinjaTrader.Gui.Chart;


how to fix?


what I'm trying to do is to change the background color of all panels on the chart without changing the objects...

in Ninja 7 I used this...

ChartControl.BackColor = Color.Gold;

Hello llanqui,

Thank you for your post.

You may use the Code Breaking Changes page of the help guide to verify changes between NinjaTrader 7 and NinjaTrader 8:

https://ninjatrader.com/support/helpGuides/nt8/code_breaking_changes.htm

BackColor from NinjaTrader 7 was changed to BackBrush in NinjaTrader 8:

If you want to change the color of all panels on the chart, you may use BackBrushAll:

Please let us know if we may be of further assistance.

thank you

I am getting a compile error...

if (BackBrushAll == Brushes.LimeGreen)
BackBrushesAll = Brushes.Gold;

Cannot implicitly convert type 'System.Windows.Media.SolidColorBrush' to 'NinjaTrader.NinjaScript.BrushSeries'

[llanqui]

Ok, should be BackBrushAll not BackBrushesAll

:-)

[llanqui]

well.....NO...what I really want is ChartControl.Background, to change the background color on the entire chart

BackBrushesAll just changes the color of the background for the current bar on all panels


but when I change ChartControl.Background all the bars and plots on all panels on the Chart disappear, I assume overlayed by the Background...

basically I want to toggle the color of the chart background for different conditions, for example for printing (to change it to White)

Hello Ilanqui,

Thank you for your reply.

The correct use of the background property from ChartControl would be ChartControl.Properties.ChartBackground. That said, there is a warning that these are UI properties designed to be set by the user. Attempting to modify these values through a custom script is NOT guaranteed to take effect:

https://ninjatrader.com/support/helpGuides/nt8/chartcontrol_properties.htm

If you wish to change the backbrush color for more than just the current bar, you could use BackBrushesAll with a barsAgo index to modify the collection of historical brushes for background colors on all chart panels:

ok, well, Ninja 7 I didn't have to set all the back bars...
