For questions, use https://discourse.holoviz.org/ instead! This chat is for informal discussions and debugging sessions with developers of the HoloViz.org tools (HoloViews, Datashader, Panel, hvPlot, GeoViews, Param, etc.), but user questions should go to the HoloViz Discourse site so that others won't have to ask them again.
Hi @sam-hoffman, most of the content of the pyviz websites (including datashader) are built upon notebooks. If you browse the examples folder at https://github.com/holoviz/datashader, you'll see plenty of them. Find yours, open it and click on the Edit button (a little pencil). The raw content of the notebook should be displayed (don't worry if it's a little ugly) and you should now be able to edit it and submit your edit as a new commit. This is for me the simplest and fastest way to fix a simple type. If you need to run the code of the notebook, that's a completely different story ;)
Kindly guide on this issue https://discourse.holoviz.org/t/apply-method-strange-behavior-in-html-file/646
Regarding file watching and automatic reload in the Awesome Panel Designer https://discourse.holoviz.org/t/awesome-panel-designer/643/3. Should I look to watchdog or the built in file watching in Tornado for the --dev server to enable this? I tried experiements with watchdog but could not get it working when running on Tornado. Watchdog starts a seperate thread dont know if that is a problem?
Nice about the best practices. I'm experimenting a lot with a model-services-component-view based architecture for the larger things I do. I can't really tell if its good or bad. There is a lot of code to write and its a bit difficult to work with beginners who dont understand the concept. But it really helps to break things down.
@maximlt @philippjfr guys i am eagerly waiting for your input on this issue . I made ne nuts .https://discourse.holoviz.org/t/apply-method-strange-behavior-in-html-file/646
There is a question (not from me) on stack overflow regarding Panel authentication. Maybe somebody with knowledge could take a look and provide a better answer than I can. See https://stackoverflow.com/questions/60156510/simple-authentication-using-python-panel-holoviz/61788878#61788878
I'm working on auth right now which is why I stumbled upon the question. I can get auth working with
panel serve from command line. But not with python and then .show() or pn.serve() in the python file. Is that correctly understood?
Another question regarding auth from a user on stackoverflow. I'm not capable of answering. But take a look if you have the time and knowledge. https://stackoverflow.com/questions/60169875/handling-user-authentication-in-flask-bokeh-panel-setup
Thanks @jlstevens
FYI. Holoviz, Streamlit and awesome-anel.org is discussed on this weeks edition of Python Bytes. https://pythonbytes.fm/episodes/show/181/it-s-time-to-interrogate-your-python-code
What happened to font awesome in Panel @philippjfr ? I believe there was a PR. But now i cannot find it anywhere.
Hmm. Dash Datashader? https://medium.com/rapids-ai/plotly-census-viz-dashboard-powered-by-rapids-1503b3506652
@allkindly provide me some guidelines to make my bokeh application deploy on my own server , so that i can use my bokeh application dynamically.
Thank you.
Thank you.
Regarding Bokeh the best place to ask user questions is in the Bokeh forum. See https://discourse.bokeh.org/. But see also https://docs.bokeh.org/en/latest/docs/user_guide/server.html

Thank you.
Thank you.
At lot has happened at awesome-panel.org. New template based on Material, Inclusion of PerspectiveViewer, Inclusion of ECharts and more. See https://discourse.holoviz.org/t/awesome-panel-org-change-log/66/21?u=marc
Let me know if you have questions, comments, ideas for improvements or want to try out some of the functionality but just cannot figure out how. Thanks.
@maximlt . Regarding Podcast effect. See this increase in requests/ day to awesome-panel.org after being mentioned on the podcast.

Hi all, is there a way to use panel to change one part of clim without using a RangeSlider? for instance, this works:
img = np.random.normal(size=(100,100))
hv_img = hv.Image(img)
slider = pn.widgets.RangeSlider(start=-5, end=5, value=(-1, 1), name='contrast')
hv_img = hv_img.apply.opts(clim=slider.param.value)
pn.Row(slider, hv_img)but I can't get something like this to work:
img = np.random.normal(size=(100,100))
hv_img = hv.Image(img)
slider = pn.widgets.FloatSlider(start=0, end=5, value=1, name='contrast')
hv_img = hv_img.apply.opts(clim=(-1, slider.param.value))
pn.Row(slider, hv_img)
I get an error:
ValueError: clim: tuple element is not numeric: <param.Number object at 0x7f425a624bb0>.
Hi All,
I will very thankful to you and appreciate your help.
script1, div1 = components(finalplot.get_root())
Here get_root() is use to get the parent document but do i need to use curdoc() to get the current plot in flask as my plot is dynamic with dropdown option .
# not working
script1,div1=components(finalplot.curdoc())which function i shoud call to get current document , so that when i change bokeh lot in embedded flask app then it should reflect in webpage also.
so that i can get current document on changing my plot dynamically in embedded flask app
