SetErrorBarColors — Sets the colors used for data error bars
$plot->SetErrorBarColors($error_bar_colors
)
SetErrorBarColors
sets the colors used for each
data set's error bars, in the same way SetDataColors
sets the colors used for the data plot itself.
$error_bar_colors
An array of color values, one for each data set's error bars. Or, a single color value to use for all data set error bars. See Section 3.5, “Colors” for more on color values.
The default array of error bar colors contains the same 8 colors as the data colors array: SkyBlue, green, orange, blue, orange, red, violet, and azure1. If you change the data colors with SetDataColors, you probably want to change the error bar colors to the same array.
