AFL: How to increase candlestick shadow thickness or bar chart without open and close

Hi AFL experts....
Any way to increase the candlestick shadow thickness in amibroker.

If not possible we can obtain the same by plotting bar chart without open and close by setting z-order as -1 and setting barthickness as 3 pixels.
And plotting a candlestick price chart on top of the above mentioned bar chart.

By doing this we can obtain a candlestick chart with thick shadow lines (which came from bar chart).

I tried plotting a bar chart without open but without close is not possible.

I need to plot bar chart without open and close (only vertical line of high and low).
Or how to hide the close handle in bar chart.

Thanks,
Veera....;)
