Spacing between X-axis ticks

[kurtzky]

My chart data refreshes every 3 seconds. I've set the X-axis stepSize to 20 so I have a 20-second interval between ticks. But the resulting chart shows big gaps between these ticks. Is there a way to "squeeze" them so the intervals are close to each other?

Please set the duration option to a larger value, 500000 for example.
