If the value correponding to index
is valid, fills min and max with the error values:
-> positive_error in max
.
-> negative_error in min
.
If one of the errors is not valid or not defined, its value is set to -1.0.

);
Displays the error bar. If plus
is negative, the positive side of the bar is not displayed,
and if minus
is negative, the negative side of the bar is not displayed.
x_map and y_map are used to convert coordinates from data space to canvas coordinates.
This function must not be called if gog_error_bar_get_bounds returned FALSE.
