addTrace with type: 'scattergl' does not show previous traces #133
Description
I am currently implementing Scatter Plots to graph certain sensor data coming in from robots, the amount of data that comes in becomes to much for just 'scatter' and makes the web app pretty much unusable.
It may be similar to #130 but this is more really basic as you can have multiple traces working if you add them at creation, but not add them using addTrace.
