If I fill the y- axis with points (seconds)

now can i set a rule that each point gets formatted according
to the number of seconds

example: 100 - should display 1m 40 seconds, and likewise


is this possible?

Hi shahiddarbar,

You may set the format string to {value|hh:nn:ss}. For example, in C#/Java:

c.yAxis().setLabelFormat("{value|hh:nn:ss}");

Hope this can help.

Hi shahiddarbar,

If you would like to set the axis scale with your code, you can always set the scale and specify the labels to use by using Axis.setLinearScale2 or Axis.setDateScale2.

If you would ChartDirector to auto-scale the axis and determine the label position, but what to use a special formatting scheme that is not built into ChartDirector, you may use custom formatting. First, your code can use BaseChart.layout to ask ChartDirector to auto-scale the axis (this should be done after your code has entered all the data to the chart object). After that, your code can use Axis.getTicks to ask ChartDirector for the label positions, then use Axis.addLabel to specify the label to use at those positions.

An example is at:
