Line Chart dataPoints always use the color of the first line

[danzel]

This reproduces in the documentation
http://rma-consulting.github.io/react-easy-chart/line-chart/index.html#dataPoints
On the chart, all of the circles for data points are grey, the same color as the first line.

If you customise the color of the lines using lineColors={['#9999ff', '#99ff99']}, all of the dataPoint circles end up with the new first line color (blue in this case).
