Funnels may show the gradual conversion of an initial set of individuals. Our Funnel Bars chart shows the road from identifying potential customers, to recruit them, and to finally make them stick with the seller. Such chart is not natively supported by CanvasJS. We emulate it with a Range Bars chart, and we take care to position each bar symmetrically, in the middle of the plot area. We turn the data labels on and that's it, isn't it? ...Not so fast. Range charts show two data labels for each bar, and we don't want this. To show one single value, in the center, we have to use another hack, with fully transparent strip lines over the data bars. To each strip line we may assign a label. Which will be properly displayed now, in the center of each bar.
