kandi X-RAY | panel Summary

panel is a Python library. panel has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can install using 'pip install panel' or download it from GitHub, PyPI.

Panel provides tools for easily composing widgets, plots, tables, and other viewable objects and controls into custom analysis tools, apps, and dashboards. Panel works with visualizations from Altair, Bokeh, HoloViews, Matplotlib, Plotly, pydeck, PyVista and many other Python plotting libraries, making them instantly viewable either individually or when combined with interactive widgets that control them. Panel works equally well in Jupyter Notebooks, for creating quick data-exploration tools, or as standalone deployed apps and dashboards, and allows you to easily switch between those contexts as needed.

            How can I make a discontinuous axis in R with ggplot2?
            Asked 2022-Mar-30 at 07:09

            I have a dataframe (dat) with two columns 1) Month and 2) Value. I would like to highlight that the x-axis is not continuous in my boxplot by interrupting the x-axis with two angled lines on the x-axis that are empty between the angled lines.

            Example Data and Boxplot



            Answered 2021-Oct-12 at 02:18

            You could use facet_wrap. If you assign the first 3 months to one group, and the other months to another, then you can produce two plots that are side by side and use a single y axis.

            It's not exactly what you want, but it will show the data effectively, and highlights the fact that the x axis is not continuous.



            Make a div scrollable inside flexbox
            Asked 2022-Feb-08 at 18:20

            I have a sidebar that contains 2 panes. When I resize the window vertically, I want the top pane to dynamically resize, and the bottom pane to remain to a fixed size. When the total height of the sidebar is smaller than both panes, I want the top pane to shrink smaller than it's content, and become scrollable.

            The expected behavior is the same as VS Code's sidebar.

            Currently, when resizing, the top pane "pushes" the bottom pane down.

            Is there way in ggplot2 to place text on a curved path?
            Asked 2022-Feb-02 at 10:17

            Is there a way to put text along a density line, or for that matter, any path, in ggplot2? By that, I mean either once as a label, in this style of xkcd: 1835, 1950 (middle panel), 1392, or 2234 (middle panel). Alternatively, is there a way to have the line be repeating text, such as this xkcd #930 ? My apologies for all the xkcd, I'm not sure what these styles are called, and it's the only place I can think of that I've seen this before to differentiate areas in this way.

            Note: I'm not talking about the hand-drawn xkcd style, nor putting flat labels at the top

            I know I can place a straight/flat piece of text, such as via annotate or geom_text, but I'm curious about bending such text so it appears to be along the curve of the data.

            I'm also curious if there is a name for this style of text-along-line?

            Example ggplot2 graph using annotate(...):

            Great question. I have often thought about this. I don't know of any packages that allow it natively, but it's not terribly difficult to do it yourself, since geom_text accepts angle as an aesthetic mapping.

            Say we have the following plot:

            Reason of the issue

            It is expected browserslist to return an entry for each version ("safari 15.2", "safari 15.3") instead of a range ("safari 15.2-15.3"). So, this is just a bug in the parsing logic of Safari browser versions which needs to be corrected and will be done soon in fixed versions of Angular 12/Angular 13. Link to details is here.


            This is fixed in v12.2.16 and v13.2.1, please update if you are experiencing this issue. Users on v11 shouldn't be affected. Link to details is here. If you can not/do not want to update for any reason, then one of the workarounds below can be used.

            How to define an icon for a custom product data tab in WooCommerce
            Asked 2021-Dec-19 at 17:15

            I have created a custom product data tab in WooCommere using:



            Answered 2021-Dec-19 at 17:15

            html-product-data-panel.php is not a template file. So NEVER EDIT PLUGIN FILES! When WooCommerce gets updated, it overwrites the installation with any new updates included in the release. If the core has been chopped up and modified beforehand, it’ll wipe out those changes.

            That means big sections of the installation will just stop working. Modifying the core can have all kinds of unintended consequences, like preventing updates from working correctly, further screwing up an installation.

            Even worse is the potential to introduce unintended security vulnerabilities. Messing with core files could easily introduce a hole allowing hackers to take over a site.

            The icon is assigned via CSS:

            The issue is coming from _isOpen because it contains only two value but used on five widgets. We need to make the list that will contain five bool in this case.

            List _isOpen = [true, false, false, false, false];

            And use unique index on each ExpansionPanel
