Description
The appearance of the error bars can be controlled by using the ErrorBarStyle() function. The 1st argument seriesIndex defines which data series the function refers to. The 2nd argument axisIndex defines which error bar direction the function refers to. By activating the argument showCapsOnly = on, the connecting lines between the error markers can be suppressed. The length of the error markers (in pixels) can be controlled by using the argument capLength. The bar stroke and color can be varied using the arguments barStroke, barColor and barColorVariant. Unless otherwise defined, error bars are black and one-pixel wide.
