Chart options panels went through some reorganization. Now we have "Current category label" panel:
and "Animation" panel:
For charts with multiple data rows that are considered categories (pie, regular bar and comparative histogram charts), charte.ca can walk through all categories and update the appearance, creating an animation effect - see chart below.
Try it for yourself - create a pie, regular bar or comparative histogram chart with multiple data rows and play with animation settings. The feature comes handy when you embed charte.ca visualization into a presentation and do not have a convenient way to click or hover over the chart to navigate between categories.
