Chartjs-Why the labels under chart are not corresponding with labels in legend in Chart.js for bar chart?

The data.labels defines the ticks for a category axis. Following your configuration, the chart is expecting to have 3 data items for dataset, (first at tick ‘a’, second at tick ‘b’, third at tick ‘c’).
Instead, the dataset.label are used in the legend.

In your config, all datasets have got only 1 value and all values are related to the first data.labels, ‘a’.
