Changing bar color gradient

[Hawk1]

Hi Support,

How can I color my bars dynamically to vary (in a gradient way) from 2 colors like gray to green based on a certain calculation at the time.

thanks

Hi Hawk, thanks for posting.

We have an example of gradient bars based on RSI here:

thanks for quick response,

1. Is there a way to see the code of these ecosystem indicators without downloading them on to your platform? My concern is that there might be some sort of malicious dll that is attached and I don't want to find out after it's downloaded on my platform.

2.I've looked thru the forum regarding the RSI gradient color change and it appeared to to what I want except it could only vary between red, blue or Green. Is there a way to vary between 2 preset colors like Gray and Green?

3. I tried using the LinearGradientBrush but I'm guessing that's not the correct way of accomplishing this?

Hi Hawk1,

1. You can download the .zip then look within the .zip file and use your preferred code editor to view the script. We do not allow .dll files to be uploaded to the Ecosystem website or forum and most browsers will warn if there is a .dll file in a zip file when you download it. Visual Studio Code also has a protected view by default when you open files.

2. The code within the script will need to be modified for custom colors. The colors are calculated within OnBarUpdate i.e. on each bar so to change for custom colors would take a few specific changes to the RGB calculations taking place.

3. LinearGradientBrush does not apply here because BarBrush is a Brush type. On each bar the BarBrush color is set based on the RSI value. When you group the bars together it looks like a gradient.

Kind regards,
