Under My Tools in the left menu, and below the Sliders, select Bar Effect Slider to navigate to a page containing a list of your sliders with bar effect or create a new one. When the slider setting page is opened, like other tools, please choose a desired name for your slider. After that, you have to fill the other inputs. The first input is a place to paste the desired sliders images. The second one is for defining the bar size in the format Width x Height. The bars count and speed of transition should be entered afterwards. Finally, you have to define the background color either in Hex format or RGBA.
Simply see the preview and copy the code and use it wherever you like.
