 Trackline with Legend data labels |

Hi,
We are using the trackline with legend functionality with multiple axis.
Some of the series / axis are qualitative in nature and the axis are populated with setLabel()
Is it possible for the legend to display the axis label (has meaning) instead of the data value (only used for sorting)
Many Thanks

Hi Emilio,
Yes, you can use JsAxis.getFormattedLabel to obtain the label on an axis given a value on the axis. By default, if your axis is configured using Axis.setLabels, the value for those labels will be the array index 0, 1, 2, 3, ..... The "Track Box with Floating Legend (Web)" example demonstrates how to use this API for the x-axis. You can use it for the y-axis as well.
In brief, if your axis is configured with Axis.setLabels, then c.yAxis().getFormattedLabel(N) will be the (N+1)th label on the axis. If your data points are using that axis, the point data value should be integers to align with the labels. So the label for a point must be
c.yAxis().getFormattedLabel(pointValue).
Hope this can help.

Thanks that's awesome.
In my scenario I have multiple y-axis and yaxis2. How can refer to the correct axis to get the formatted label? |

Hi Emilio,
Instead of using c.yAxis().getFormattedLabel(N), may be try myDataSet.getUseYAxis().getFormattedLabel(N), where myDataSet is the data set that your data value comes from.

Hope this can help.
