¶ Plotting in Divooka
There are four levels of plotting in Divooka:
- Quick, high-level, one-shot plotting
- Slightly more advanced configuration based plotting for standard charts
- Specialized plotting types with varying levels of customization
- In additional to above three, we also support text-based drawing with Dhole
At the moment Divooka doesn't have a way for you to draw completely custom plots - if that's desirable, consider using lower level drawing API and image composition API instead.
In this note, we will go through each type below, and for more details, please refer to API doc or library specific documentation.
¶ Summary of Available Plots
(Work in progress)
¶ Standard
| Plot | Location | Purpose | Configurations |
|---|---|---|---|
| Scatter Plot | Quick Plot | Scatter or line chart. | Pending |
¶ Dhole Charts
| Chart | Syntax Example | Equivalance |
|---|---|---|
| Table | ... | ... |
¶ 1. High Level Quick Plotting
Plotting is typically provided in Plotting > Quick Plot toolbox, with additional configurations in Plotting Configurations category.
To draw a given plot, pick the plot type node, then supply required parameters.
¶ 2. Configuration Based Standard Plots
This method has limitation on the possible type of plots and may become cumbersome for advanced customization.
