chart labels

Hi,
 
Is there a way to limit the number of data labels on x-Axis? ex:display only 3 or 4 labels (one first, last and middle). The first and last labels will be displayed always.
 
The limit is only for labels and all data points should be plotted.
 
Chart Type: SVG
Birt Version: Actuate BIRT Designer Professional 
<div>Version: 4.4.0</div>
 
I attached the sample report. Parameter(daysRequired) for number of days to generate categories for x-axis
 
Thanks
Suresh

Hi,
 
Before using scripting to do this, have you considered using an HTML5 chart with a Timeline Bottom Slider? This is a better way to display time series on the X-Axis. The chart on the right in the attached report sample shows one example.
 
Otherwise, if you need to use SVG, here's a link to a previous post:

Hi,
 
I'm working on a similar scenario. I'm using birt 2.6.2 to develop the chart. 
The thread you posted displays the first and last values through the aggregation which you added in the grid. But I have a lot of values that would be displayed on the x-axis. The last value isn't appearing if I use the code from your working example 1 (ShowFirstLastLabelChart). I need the first and last values to be displayed with a minimum number of labels to be displayed between them. Let's say a number of 8 to 12, so that while displaying, all the labels will not pop up and I still have the first and last values to show.
The data points should not be limited. All the data points should be plotted.
 
Can you please let me know the scripting that I needed to use in order to achieve it?
 
Thanks,
