Infinite loop when data indicates horizontal line

[observerss]

for data looks like this

var day_data = [
{"period": "2012-10-01", "licensed": 0, "sorned": 0},
{"period": "2012-09-30", "licensed": 0, "sorned": 0},
{"period": "2012-09-29", "licensed": 0, "sorned": 0},
{"period": "2012-09-20", "licensed": 0, "sorned": 0},
{"period": "2012-09-19", "licensed": 0, "sorned": 0},
{"period": "2012-09-18", "licensed": 0, "sorned": 0},
{"period": "2012-09-17", "licensed": 0, "sorned": 0},
{"period": "2012-09-16", "licensed": 0, "sorned": 0},
{"period": "2012-09-15", "licensed": 0, "sorned": 0},
{"period": "2012-09-10", "licensed": 0, "sorned": 0}
];

this.yInterval = 0

drawGrid mehtod will run into a infinite loop.

my workaround:

add the code below before "this.dirty = true; "

  if (this.yInterval == 0){
    this.options.ymax += 1;
    this.yInterval = 1;
  }

I got the similar problem if all of the y-key with zero value, and from the console I found Error: Problem parsing d="H725"

my data looks like this

[{"date":"2012-07-01","value":0},{"date":"2012-07-02","value":0},{"date":"2012-07-03","value":0}]

@observerss your workaround doesn't work for me, could you paste your full code?

This is fixed on master now.

I also recommend using an auto N value in the ymax and/or ymin options, so you can set the range that the graph will show when there's absolutely no variance in the data values.

@oesmith thanks a lot, you save my day
