How To

A mini how-to for Pygoda.

Pygoda interface is packed with many tooltips. You can get a lot of information on how to use Pygoda simply by hovering the different elements of its GUI.

Displaying the time series

  • Plot more/less stations: go to menu Grid/Grid geometry

  • Plot another subset of stations (#1): select another grid page in the combo on the left above the grid

  • Plot another subset of stations (#2): click on one of the arrow next to the aforementioned combo

  • Plot another subset of stations (#3): press LEFT (previous page) or RIGHT (next page) arrow while holding CTRL [grid must have focus]

Customising the subplots

  • Adjust the time span: tick t-sync and pick the starting and ending dates

  • Adjust the Y-axis range: tick y-sync, pick a reference level and bound type in corresponding combos (hover for tooltips), and set the lower and upper bounds

Computing time series characteristics (features), fitting models and sorting

  • Compute time series features and sorting: select a parameter (aka feature) in the combo initially displaying ‘Sorted by default order’

  • Display a feature while sorting with another one: select the feature you want to display, then hold SHIFT and select the feature used for sorting OR select the feature used for sorting, then hold CTRL and select the feature you want to display (hover for tooltips)

  • Fit a model: chose a model in the Fitted models group and pick one of the model parameter

  • Reverse the sort order: tick or untick the ‘Decreasing order’ box

Selection

  • Select a station: left click on a subplot or on a map

  • Select another station (#1): left click on another station

  • Select another station (#2): press LEFT (previous station) or RIGHT (next station) arrow

  • Select several stations: left click while holding CTRL

  • End selection: right click on any subplot or anywhere on a map

Categories (default behaviour, can be configured)

  • View another group of category (#1): select another group in the top left combo

  • View another group of category (#2): hold CTRL and press 0, 1, …or 9 [category combo must have focus]

  • Set a station category (#1): repeat left (next category) or right (previous category) click on a subplot while holding SHIFT

  • Set a station category (#2): select a subplot, then press + (next category) or - (previous category)

  • Set a station category (#3): hover a subplot, then press 1, 2, …or 9 (or 0 to assign no category); then the next station will be automatically selected [grid must have focus]

  • Toggle a station category: press SPACE while hovering a subplot [grid must have focus]

Zoom plot

  • Snap crosshair to closest data point: hover with mouse cursor (buggy for now!)

  • Snap crosshair to closest date: hover while holding CTRL

  • Snap crosshair to closest data value: hover while holding SHIFT

  • Compute basic statistics over an interval: left click once to set the starting date and left click a second time to set the ending date; click one more time to reset

Cartopy map

  • Zoom in and out: scroll over the map

  • Pan the map: hold left click anywhere and pan

  • Set the reference point (used for sorting): hold CTRL and middle click on the map at the location of your choice

  • Filter the stations by region (only when using an overlay): middle click in the region of your choice

Leaflet map

  • Change the map layer: pick another layer in the bottom-left menu

  • Plot a time series directly on the map: right click on a station
