plot.redraw() throws Cannot read property 'nodeName' of undefined #62

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. I have a plot with (width and height set to 100%)
2. I set a series with some data and draw it
3. A user clicks a button and I: 
  seriesHandler.clear();
  for (int i = 1; i < data.length; i++) {
    seriesHandler.add(new DataPoint(i, data[i]));
  }
  plot.redraw()

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
I tried it with 3.0.1 and 2.4.3 
on chromium on ubuntu

Please provide any additional information below.
I now just create the plot from scratch whenever I need to change something, 
which seems to work

I can't reproduce the problem.
Are you doing anything special ? Is your plot visible when you call redraw ?

GoogleCodeExporter commented 9 years ago 
no it is not visible.
Let me know if you need me to try anything or provide more detail.

Can you defer the redraw and wait that the plot become visible ?
Flot requires the container to be visible. It is somewhere in their FAQ.
It's odd than creating a new plot is working. it should also fail.

ok thanks, I didn't see that.

even updating the model while the graph is not visable (on another tab) throws 
an exception:

java.lang.IncompatibleClassChangeError: Found interface 
com.googlecode.gflot.client.DataPoint, but class was expected 
happens on this line:
seriesHandler.add(DataPoint.of(1.0, 123.0));

In my case I'm quite happy to just re-create the graph so I think we can close 
this. Hopefully this bug is useful for other people in the future.
