-/**
- * This class displays a histogram. It has a list of channels it can select. The easy
- * way is to display channelStrings() to the user, and then use a setActiveChannel
- * with the integer the same as the one the selected string in that stringlist has.
- * If the selected one is a producer, the histogram will automatically display all its
- * channels, and color them if that is possible.
- *
- * You can also set the channels manually, just don't forget that the displayed channels
- * all need to belong to the same producer! If you set them manually, don't forget to set
- * the (non)usage of color as well.
- *
- * You can either set this to use a specific layer, or use a specific histogram. With the latter,
- * some functionality will disappear, like listProducers(). Setting a histogram will discard
- * info on the layer, and setting a layer will discard info on the histogram.
