Customize x-axis labels

zerba78

<p>Hi all</p><p>I use Birt designer 2.6.2 and I think it's a great tool.</p><p>I need to customize the x-axis but I don't know how to achieve the following result.</p><p>I have a bar chart that is displaying a measure for a 24 months time range, one value per month, starting from the current month and back to 2 years before. For example, if I execute the document today (July 2013) I get results for August 2011, Sept 2011, ..... June 2013, July 2013.</p><p>If I will execute the document tomorrow (August 2013) I will get values for</p><p>Sept 2011, October 2011..... July 2013, August 2013.</p><p>I want the x-axis to display only labels for first and last months and all January-s (i.e. when a new year starts) in the time range, labels to be horizontally aligned and with a tick.</p><p>I'm trying with scripting tecnique: the main problem I have is that, since the chart isn't too big, there is no enough space for all labes, therefore Birt is hiding some of them (unfortunately also the ones I need). And I don't know how to add ticks with scripts.</p><p>This is my script:</p><p> </p><p> </p><div>function beforeDrawAxisLabel( axis, label, icsc )</div><div>{</div><div>  if(axis.isCategoryAxis()){</div><div>    var labelParsed =  label.getCaption().getValue().split("-");</div><div> </div><div>    var year = labelParsed[0];  // this is the year</div><div>  var month = labelParsed[1];  // this is the month</div><div>  var rownum = labelParsed[2];  // I use this in order to understand if it is the first or last value in the range</div><div> </div><div>  if (month == '1'){</div><div>    label.getCaption().setValue(year);   // I put just the year, I hide January</div><div>  } else if ((rownum == 0 )||(rownum == 23 )) {</div><div>    label.getCaption().setValue(year+"-"+month);</div><div>  } else { </div><div>   label.getCaption().setValue("");</div><div>  }</div><div>  }</div><div>}</div><p> </p><p>Can someone give me some advices?</p><p>Thanks in advance and best regards</p><p> </p><p> </p>
