I could notice that the horizontal line uses 2 clicks and not 1 as before. changing colors in the lines and box work well. I could see that the center of the rectangle always remains gray and only the edges change color. deleting the drawings do not work or styles do not work either. Suggestion for styles to be able to adjust the tickness of the lines please. Otherwise it works very well, I will be testing it more thoroughly to see if I find more problems. A request for future fibbonacci retracement. Good job, the light weight charts python project looks better every day. |
After second click on horizontal line cant move again. if change time frame drawings desappear and When you return to the tf where the drawings were created, they appear. |
Thanks for your feedback @cilindro5432, ill get those ironed out soon. |
@louisnw01 How to use this new 2.0 version |
I would love if you can simply make the drawing tools color/behaviour default to same as in tradingview app. They are pretty good already |
Great to hear, thanks for all your work on this @louisnw01 ! Will there be support for PyQt6 in this version? |
I have waited for long for BOX / RECTANGLE to be implemented thanks for your great work. One suggestion if possible add some examples for BANDs like macd. |
Hello, can someone help me set up lightweight-charts on Ubuntu 20.4 WLS Installation? I managed to get a static chart but no live one, I get an error about python gtk which I cannot resolve. I use Python 3.11 on Anaconda. Sorry for posting this, maybe a Q&A like armeya25 said would be usefull |
horizontal lines are back to a single click, delete should work now. Louis |
I have added an installation section to this issue. Louis |
Hi Mr. Lois |
@armeya25 If you dont have any or just a little knolodge in python try chat gpt to setup your chat. |
I am noob in python but I used lightweight charts before it was working fine for 2.0 it's shows error for same code that was working fine for older version of lightweight charts |
I had some issues with my code too in first version of this branch. The first version of this branch had several problems when starting the app. I had to modify my code. The second version does not have these problems, try with the latest update of light weight charts. As I told you, if you don't have much experience in python, chat gpt can help you a lot, it can identify errors more clearly. |
export WEBKIT_DISABLE_COMPOSITING_MODE="1" After this command works on arch linux i3wm |
@louisnw01 box implementation working or not |
My drawing doesn't disappeared though, |
Should that also be raised as big ? |
"A complete rework of the backend, which now uses TypeScript Some ideas that others could contribute: Fib lines You want a marker as rectangle. Now is time to be creative |
It gives error : |
My app has a lot of early development rust on it at this point. Very excited for the next 2.0 release so I can finally rebuild it. Thanks for your hard work, Louis. Without this library a lot of the ideas would just stay in our heads forever. |
Encountered a bug in 2.0 presented here: |
in python-lightweight-charts v 2.0 adding marker throwing the following error:
Exception in thread Thread-2 (loop): During handling of the above exception, another exception occurred: Traceback (most recent call last): script -> ' |
Is this v2.0 based on https://github.com/rwitzlib/lightweight-charts fork ? |
Nope; all drawing plugins have only been written by me (so far) |
Fixed |
I am receiving following error when I am doing following:
When I get a bar data for a perticulat stock I create indicators and set them. I search the stock and set the candle data for another stock and now I have to delete the old indicator lines and recreate and reset them.Exception in thread Thread-2 (loop): During handling of the above exception, another exception occurred: Traceback (most recent call last): |
@louisnw01 I think clear_markers missing self._update_markers() call after the clear. |
Hello everyone!
I have created a new 2.0 branch which i’m planning on releasing in the coming days/weeks. It includes:
Now that we are using plugins (and the js/ts source code is readable!) I hope that it will be easier for others to contribute their own ideas, especially on the typescript/javascript side of things.
Some ideas that others could contribute:
Any feedback/testing would be much appreciated!
To Install this branch:
pip uninstall lightweight_charts
pip install -e path/to/lightweight-charts-python/lightweight_charts/
