Line chart's X-Axis labels are not showing completely

[skkuchipudi]

hi,

i have one line chart having morethan 7 X-axis labels. when i execute my code the chart is displaying well but the X-axis labels are not displaying completely. those are displaying as following sequence.

24/3.. 25/3.. 26/3.. 27/3.. 28/3.. 30/3.. 31/3..

but i have to get the full dates as the following sequence.

24/3/2006 25/3/2006 26/3/2006 27/3/2006 28/3/2006 30/3/2006 31/3/2006


could you please anyone give me the suggestion.

regards,
Sumant

i have the same problem as yours, when i drop or delete the domain label it displayed well, but its not a solution...but you can place the domain label somewhere else maybe at the right.
i want to display the domain label at the left in the corner but i couldn't do so.

maybe you could try having the labels on an angle instead of horizontal to allow for more room for the text..

It looks like you are using a CategoryAxis to display a value scale. It would be better to use a DateAxis (with an XYPlot), since it handles the tick spacing automatically.

i hope you will give the suggestion


thanks,

Code: Select all

public class WeeklyLineChart extends ApplicationFrame {

     super(title);
