Incubator-echarts: how do I clear a chart? Basically I need to re-initialize it.

[stevelacerda7]

I have several charts on a single page, and each chart changes based on what the user selects. I have an ajax call that retrieves the data, so the data varies and is dynamic based on users selection. I'm having a problem clearing out old data. Basically, I just want after each selection to re-initialize the chart and start from scratch. How can I do that?

It seems that now, when the user deselects a metric, the chart retains that old information. I've tried setting data to null, or empty array, but nothing seems to work.

setOption(newOption, true) will clear the previous data and use the new one.

setOption(newOption, true) is still leaving old data on the chart.

mychart.clear()
