Sample Data
Steps/Function to support
Step | Task | Visual Encoding & Interaction | Goal | Input Data | Output (Data) | Issue | Status |
---|---|---|---|---|---|---|---|
(1.1) | Load data sets to explore | via Drag'n'Drop | have data available for parsing | separated model input parameters and model result output as CSV | linestrings of provided input and output files | de-prototypes#161 | |
(1.2) | Parse file contents and store data in traversable datastructure | trigger via button or automatic? | prepare data for visualization | linestrings of input and output files | traversable datastructure | de-prototypes#166 | |
(2) [optional] | Identify most sensitive input output combinations | tornado-plot / stack-bar-chart | Provide entry point for further exploration | traversable datastructure | - | ||
(3) | Data visualization | line plot with marked data points for user selected input and output parameters | exploration | traversable datastructure and input parameter permutation provided by the user | spr visualization | de-prototypes#168 | |
(3.1) | Display X Axis with stacked input parameters | parameter hierarchy derived from the input parameter sequence | support visual exploration | input parameter permutation provided by the user | |||
(4) | Data exploration | interactive components | gain insight in input-output relations | ||||
(4.1) | change sequence of stacked input parameters | list with draggable items | set custom parameter sequence used by the chart vis | list of available input parameters | list of input parameters in traverse sequence | de-prototypes#169 | |
(4.2) | define input parameters with fixed values | toggle and dropdown menu with possible values | define set of parameters with fixed values | parameter with list of unique values | mapping of selected fixed parameters with the corresponding value | #6 (closed) https://git.geomar.de/digital-earth/de-frontend-framework/-/issues/9 | |
(4.3) | select rendered output parameter | select from dropdown list | set output parameter that is rendered by the chart vis | list of available output parameters | single output parameter |
