Ok, probably I need somthing like this:

GimpHistWidget* gimp_histogram_new();
void gimp_histogram_set_data(int* y_vals, int* x_vals, int size);
void gimp_histogram_read_data(int** y_vals, int** x_vals, int* size);
void gimp_histogram_set_callback(GimpCallBack* callback); // sets callback
on user-select-action of histogram diapazon (like in core Histogramm
widget), widget provides callback with information of x0 and x1 of diapazon
void gimp_histogram_delete(GimpHistWidget* histogram);
