Hello,
I am using org.eclipse.rap.chartjs as our RAP chart provider.
My question is:
When using Bar chart to show data for every months of 3 years, we'll specify 3 colors for the 3 years, each color represents one year(12 bars), then how to show "labels & years" on the top of the chart?
It usually looks like a small square filled with a color(same as its corresponding bars'), and followed with the year number right side, users can tell which color is which year by "labels & years" indicator.
I know It's like setting "chart.data.datasets[x].label" in Chart.js, I also modified function toJson() in ChartRowData.java, added '.add( "label", "2021")', the "label" can be received by Chart.js, but never shows "labels & years" indicator on the top of chart.
I don't know much of JavaScript.
How can I achieve that?
Thank you!
David Lee
