`<a class="el" href="structIRockyCurveCollectionData.xhtml">IRockyCurveCollectionData</a>` is a data structure intended to hold data that will be used by Rocky to create a custom collection of cross plot curves and/or time curves for particles and geometries.

A curve is composed of a pair of domain and image datasets. A dataset is a set of values that may change over time in values and size. When creating a dataset, one must provide its name and unit. During the simulation, such datasets must be updated with custom data, which will be written on disk by Rocky at output times. The most adequate hook to perform that data update is `ROCKY_PLUGIN_PRE_OUTPUT`, because it is executed immediately before the data output. However, depending on the particular needs of the module, that operation can be done in other hooks as well. After an output operation, all dataset values are automatically erased, and must be updated again for the next output. At any given output, a domain and an image datasets for a cross-plot curve must have the same size, otherwise an error will be thrown.

It only works with time curves previously created using `<a class="el" href="#aab6ad0a64db6e08afcc4c09643f2fbaa">IRockyCurveCollectionData::create_geometry_time_curve</a>`, otherwise it throws an error.Parameters geometry\_idThe geometry unique identifier (index) nameThe name of the time curve. valueThe value to be appended into the curve.
