Scientific mode
PyCharm allows you to perform scientific computing and data visualization using Python.
Note that to work with Matplotlib, Numpy, Plotly, or pandas, you need to install these packages on your Python interpreter.
Analyze data
View data structures
When viewing variables in the Python Console, you can click View as Array, View as DataFrame, or View as Series links to display the data in the Data View tool window.
By default, the new table representation is used. Click
Switch Between Table Representations to change the table interface.Click Table Coloring Options to toggle and configure cell coloring.
Use the Format field to adjust the data frame formatting.
Dataframes and series can be displayed in tabular or graphical form. By default, tables are shown. To toggle the view mode, use the corresponding icons in the upper left corner.
Work with tables
To open the table search bar, click the table and press Ctrl+F.
To open the context menu, right-click the column name:
To copy the column name to the clipboard, select Copy Column Name.
To select the entire column, select Select Column.
To hide a column, select Hide Column. Hide Other Columns will hide all columns except the selected one.
To display hidden columns, click Columns List Ctrl+F12. The hidden columns are shown strikethrough. Select a column and press Space to toggle its visibility. To search through the column list, start typing a column name in the Columns List window.
To assign a language to a column, use Set Highlighting Language. For more information, refer to Inject a language for a column.
Sort data
To sort the table data based on the column values, you can either click the column name or select Ascending or Descending from the ORDER BY section in the context menu.
To add another column to sorting, you can either click the column name while pressing Alt or select Ascending or Descending from the Add to ORDER BY section in the context menu.
The data will be sorted by selected columns.
State
Description
Indicates that the data is not sorted in this column. The initial state of the sorting marker.
The data is sorted in the ascending order.
The data is sorted in the descending order.
The number to the right of the marker (1 on the picture) is the sorting level. You can sort by more than one column. In such cases, different columns will have different sorting levels.
Filter data
Click Open Filter View in the upper-right corner of the table.
In the dialog that opens, select the column where you want to apply the filter and specify the filter criteria.
If you want to use additional filters, click Add filter and specify the new filter criteria.
Click Apply to filter data.
To remove or duplicate a filter, click 
Additional Filter Actions and select the required option from the list.
View column statistics
By default, column statistics are turned off.
To change the default mode to Compact or Detailed, navigate to .
The Compact mode includes only Missing and Count statistics:
For numeric data, histograms are plotted and shown together with statistics. Hover over the histogram to view detailed information about each bar.
To view detailed column statistics, do one of the following:
Hover over a column name. A popup with column statistics appears.
Click
Show Column Statistics and select Detailed.The detailed statistics are shown above the columns.

Work with charts
To view dataframes or series in a graphical form, click Show Chart.
The data will be displayed in the form of a chart. You can change the type of chart and configure additional settings.
Configure charts
Click
Show series settings to change the initial settings of the chart.Select the chart type and configure the settings. You can choose one of the following chart types:
Bar

Bubble
Stock
AreaRange- Histogram
Click the Add new series link to add more series to the chart.
Save a chart as an image
Click
Export to PNG to save the generated chart in the .png format.Enter the filename and click Save.
View data visualizations
Data visualizations are displayed in the Plots tool window, allowing you to resize it and to zoom it in and out.
To save a plot, right-click the preview thumbnail and select Save as Image or Save All Plots from the context menu.
When stopping on a breakpoint, the plot being debugged appears in the Plots tool window. See the Debug section of the Data Science project tutorial.
Matplotlib and Plotly are also available in the console. See the Running in console section of the Data Science project tutorial. When starting a Python console (), one can import required packages and build graphs as required:
The Python console is accessible for further inputs.
