Qgrid examples python

Free jqGrid is a JavaScript plugin that displays table-based data in a lot of different configurations. It supports client-side paging, sorting and filtering on server-side. One can group the displayed data, create the data as pivot table made aggregation of datadisplay the data in the Tree form creates subgrids and so on.

One can easily implement tree variants of editing of local or remote data. The large number of possibilities makes it difficult for a newcomer to start using jqGrid. The information below provides basic free jqGrid knowledge to make it easier to get started quickly. We will just include some small "advanced" options in some demos, mostly to show the diversity of customization possibilities.

Finally one should call jQuery " tableId". Different options of free jqGrid provides the data of the table body and the information about the outer part of the grid. For example, the code below. Please use the demonstration grid above to sample just a few of the functionalities free jqGrid offers. One can use, for example, Chrome developer tools to examine the grid after creating:.

One don't need to know all internals of the grid, but it's important to understand some basis facts:. One can for example create custom tooltip text or to remove it. One can prevent hovering or rows. One can prevent allow to select multiple rows, to prevert unselection of rows on the second click on previously seceted row, It's important curretly just to understand the basis features existing in every grid. The custumization of the features will be described later.

The input data contains typically not only strings, but numbers, dates and so on. One uses typically some locale independend format for transfering the data like One want typically display the data in some locale format likeMoreover the data in the column should be sorted based on the type of data and not as its locale string representation. One can include in colModel additional properties, which specify the behavior specific for formatting, sorting editing and so on.

For example, one can specify align: "center" or align: "right" to change the default alignment of the text in the cells. One can use width property, for example, width:to change the default width px of the column. One can use sorttype: "number" in the column which holds numbers to change the default sorting befavior. One can use additionally property formatter: "number" to display the number using decimal and thousands separator specific for the current locale.

The default locale included in jquery.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. This allows you to explore your DataFrames with intuitive scrolling, sorting, and filtering controls, as well as edit your DataFrames by double clicking cells.

QGrid: An interactive grid for sorting, filtering, and editing DataFrames

Qgrid was developed for use in Quantopian's hosted research environment and is available for use in that environment as of June Quantopian also offers a fully managed service for professionals that includes Qgrid, Zipline, Alphalens, Pyfolio, FactSet data, and more. Qgrid author Tim Shawver recently did a live webinar about Qgrid, and the recording of the webinar is now available on YouTube.

This talk will be interesting both for people that are new to Qgrid, as well as longtime fans that are interested in learning more about the project. Click the badge below to try out the latest beta of qgrid in Quantopian's hosted research environment. If you're already signed into Quantopian you'll be brought directly to the demo notebook.

Otherwise you'll be prompted to register it's free :. For both binder links, you'll see a brief loading screen while a server is being created for you in the cloud. This shouldn't take more than a minute, and usually completes in under 10 seconds. The binder demos generally will be using the most recent stable release of qgrid, so features that were added in a recent beta version may not be available in those demos.

For people who would rather not go to another page to try out qgrid for real, here's the tldr; version:. API documentation is hosted on readthedocs. First, go through the normal installation steps above as you normally would when using qgrid in the notebook. If you haven't already install jupyterlab and enabled ipywidgets, do that first with the following lines:.

At this point if you run jupyter lab normally with the 'jupyter lab' command, you should be able to use qgrid in notebooks as you normally would. Please Note: Jupyterlab support has been tested with jupyterlab 0.

This allows you to do things like explicitly specify which column should be sortable, editable, etc. For example, if you wanted to prevent editing on all columns except for a column named 'A', you could do the following:. Disable editing on a per-row basis as of 1. In particular it allows a user to specify, using python code, whether or not a particular row should be editable. For example, to make it so only rows in the grid where the 'status' column is set to 'active' are editable, you might use the following code:.

New API methods for dynamically updating an existing qgrid widget as of 1. Improved MultiIndex Support as of 1. Qgrid runs on Python 2 or 3. You'll also need pip for the installation steps below. These are listed in requirements.

There are a couple of demo notebooks in the qgrid-notebooks repository which will help you get familiar with the functionality that qgrid provides. Here are the steps to clone the qgrid-notebooks repository and open a demo notebook:. Install qgrid by following the instructions in the Installation section above, if you haven't already.It offers a more consistent API.

This is how the authors describe the library. Declarative statistical visualization library for Python. What does it mean is that it focuses on what to plot instead of how to plot, and you can easily combine different components like ggplot.

Before I jump into the library, I want to quickly introduce two great tools that are useful for data exploratory. You can easily add more interactiveness to libraries like seaborn or matplotlib.

Check out some simple examples on GithubI have included most of the example in the repository. You can add Slicer, Button, and Checkbox inside a notebook. Here are some nice projects that use ipywidgets. Here the plot shows the average waiting time by hospitals, while the ipywidgets here simply add a dropdown menu that you can change the color of the plot interactively. This is extremely useful when you are trying to understand your data, instead of typing a lot of code, you can sort your data with a click, filter some data temporarily with one click.

The above gif gives you a sense of how easy it could be. With just 1 line of code, you can change the behavior of the chart. Interactiveness is crucial for data exploratory, as often you want to drill down on a certain subset of the data.

Functions like cross-filtering are very common in Excel or Tableau. If you have used matplotlibyou probably try to look up the doc a lot of times. For example, a b mean stacking Chart a and Chart b horizontally. The ability to overlay two charts is substantial, it allows us to plot two charts on the same graph without actually joining it. Here is an example.

I have two graphs created from 2 different datasets, while they are both connected to a selection filter with the hospital name. You can find my example here. Chart A shows historical average waiting Time by hours while Chart B shows the last 30 days average waiting Time by hours.This allows you to explore your DataFrames with intuitive scrolling, sorting, and filtering controls, as well as edit your DataFrames by double clicking cells.

This page hosts only the API docs for the project. You might also be interested in these other qgrid-related resources:. Click the badge below or the link above to try out qgrid using binder. Append a row at the end of the DataFrame.

Values for the new row can be provided via the row argument, which is optional for DataFrames that have an integer index, and required otherwise. If the row argument is not provided, the last row will be duplicated and the index of the new row will be the index of the last row plus one. Change a SlickGrid grid option without rebuilding the entire grid widget. Not all options are supported at this point so this method should be considered experimental.

Select a row or rows in the UI. The indices of the rows to select are provided via the optional rows argument. Edit a cell of the grid, given the index and column of the cell to edit, as well as the new value of the cell. Get a copy of the DataFrame that was used to create the current instance of QgridWidget which reflects the current state of the UI.

This includes any sorting or filtering changes, as well as edits that have been made by double clicking cells. Get a DataFrame which reflects the current state of the UI and only includes the currently selected row s. The following bullet points describe the events listed above in more detail. Each event bullet point is followed by sub-bullets which describe the keys that will be included in the event dictionary for each event. This happens as a side effect of certain actions such as scrolling, sorting, and filtering.

The event dictionary for every type of event will contain a name key specifying the name of the event that occurred. That key is excluded from the lists of keys above to avoid redundacy.

Remove a row or rows from the DataFrame.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I don't know what those errors mean, but I would suggest looking at the sample notebook on nbviewer to see how qgrid is used. Two things that I see missing:. Apologies if the docs are confusing, I'm going to try to clean them up a bit. So, I no longer use the machine I had this issue on. I tried it on my new machine, also with safari instead of chrome and worked fine. If I run into trouble again, I will update, but for now I will close this issue. Unfortunately I have the same issue and used exactly the instructions from the example notebook.

Is there a way to debug this? And what information would you need? Browser, packages, etc?

Edit: I think copying the data to my local folder does not work, because I can't find any files there. After calling qgrid. Still, no qgrids are shown in my notebooks. I had the same problem when working with anaconda after conda install qgrid.

Finally I succeeded to get it working in anaconda as follows:. Copying the files like keluc noted fixed this issue for me I'm also using anaconda :. In case anyone is still seeing this issue, please try installing the new qgrid 1.

As you'll see in those instructions, the nbinstall step that appears to be an issue for some people is no longer required. This is because qgrid 1. I have qgrid installed via conda install qgrid but in the notebook, I get no response with; import qgrid qgrid.

There are no errors when the cell is executed. My details are:. I tried to get it going on a simple sample but no luck so far I used pip for installation on python3. Were you able to rectify the same. Same problem here - the problem was resolved by reloading the notebook - not sure what the issue was.This allows you to explore your DataFrames with intuitive scrolling, sorting, and filtering controls, as well as edit your DataFrames by double clicking cells.

If you'd like to contribute to qgrid, or just want to be able to modify the source code for your own purposes, you'll want to clone this repository and run qgrid from your local copy of the repository.

The following steps explain how to do this. Install the current project in editable mode:. If the code you need to change is in qgrid's python code, then restart the kernel of the notebook you're in and rerun any qgrid cells to see your changes take effect. If the code you need to change is in qgrid's javascript or css code, repeat step 3 to rebuild qgrid's npm package, then refresh the browser tab where you're viewing your notebook to see your changes take effect.

There is a small python test suite which can be run locally by running the command pytest in the root folder of the repository.

The read-the-docs page is generated using sphinx. If you change any doc strings or want to add something to the read-the-docs page, you can preview your changes locally before submitting a PR using the following commands:.The QGridLayout class lays out widgets in a grid.

More …. Alignment ]]]. Alignment ]. QGridLayout takes the space made available to it by its parent layout or by the parentWidgetdivides it up into rows and columns, and puts each widget it manages into the correct cell.

Columns and rows behave identically; we will discuss columns, but there are equivalent functions for rows. Each column has a minimum width and a stretch factor. The minimum width is the greatest of that set using setColumnMinimumWidth and the minimum width of each widget in that column. The stretch factor is set using setColumnStretch and determines how much of the available space the column will get over and above its necessary minimum. Normally, each managed widget or layout is put into a cell of its own using addWidget.

It is also possible for a widget to occupy multiple cells using the row and column spanning overloads of addItem and addWidget. To remove a widget from a layout, call removeWidget. Calling hide on a widget also effectively removes the widget from the layout until show is called. This illustration shows a fragment of a dialog with a five-column, three-row grid the grid is shown overlaid in magenta :.

Columns 1 and 3 are placeholders made with setColumnMinimumWidth. We used placeholder columns 1 and 3 to get the right amount of space between the columns. Note that the columns and rows are not equally wide or tall. If you want two columns to have the same width, you must set their minimum widths and stretch factors to be the same yourself. If the QGridLayout is not the top-level layout i. The normal way to add a layout is by calling addLayout on the parent layout.

Once you have added your layout you can start putting widgets and other layouts into the cells of your grid layout using addWidgetaddItemand addLayout. QGridLayout also includes two margin widths: the contents margin and the spacing.

The spacing is the width of the automatically allocated spacing between neighboring boxes. The default contents margin values are provided by the style.

The default value Qt styles specify is 9 for child widgets and 11 for windows.
