How to implement external legend in QWT 6.0?

Hi,

I found that QwtPlot removed the external legend option in Qwt 6.0.

How to implement the external legend in Qwt 6.0?

Thanks,
William

Simply by not calling QwtPlot::inserLegend. Instead you have to connect the legendDataChanged signal from the plot with the updateLegend slot of the legend manually
Have a look at legends example - the corresponding code for the external legend can be found in Plot::applySettings.
