Plotting in Divooka

There are four levels of plotting in Divooka:

1. Quick, high-level, one-shot plotting
2. Slightly more advanced configuration based plotting for standard charts
3. Specialized plotting types with varying levels of customization
4. 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.

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.
