At which data points to draw

This drop-down list is enabled only when No Line is chosen in Connect drop-down list of Style group.

Follow Symbol Draw an error bar at every drawn data point. Note that the set of data points drawn is controlled in the Data Points Display Control group on the Drop Lines tab of the Plot Details dialog.
Draw only N error bar(s) Draw only N error bars. You can type the number of error bars to be drawn in the N= edit box.
Skip each group of N For every N+1 data points, draw an error bar at the first data point, and skip the next N data points. You can specify N value in the N= edit box.

Transparency

This controls the degree of transparency of the error bar (or line connecting the error bars). Move the slider or type a desired integer from 0 to 100 in the combination box. A value of zero (0) means the symbol or line is not transparent at all, and 100 means the symbol is fully transparent.

When Follow Symbol/Line Transparency is checked, the transparency of the error bars or connecting line will match that of the symbols.
