# chart.axisLayoutRuns

When a chart with an x and a y-axis is rendered, we first pre-render the labels of both in order to measure them. Then, if either of the axis labels take up so much space that it significantly affects the length of the other axis, we repeat the process.

By default we stop at two axis layout runs, but it may be that the second run also alter the space required by either axis, for example if it causes the labels to rotate. In this situation, a subsequent redraw of the chart may cause the tick and label placement to change for apparently no reason.

Use the `axisLayoutRuns` option to set the maximum allowed number of repetitions. But keep in mind that the default value of 2 is set because every run costs performance time.

Note: Changing that option to higher than the default might decrease performance significantly, especially with bigger sets of data.
