Chart overlap values issue

Hi,
 
Chart is over lapping the values when the values are closer and hence i am unable to see the values what it is in IV. do we can avoid this? please suggest me.
 
Attached is the sample report to reproduce the issue.

You can adjust the Y positioning of the series lables on a per series basis in the chart scripting.
For Example:
<pre class="_prettyXprint _lang-js">
beforeDrawDataPoint: function(point, pointOptions, chart, seriesIndex, pointIndex)
{
if(point.series.name == "B"){
pointOptions.dataLabels = {
y: -25
}
}else if(point.series.name == "C"){
pointOptions.dataLabels = {
y: -50
}
}

},
</pre>

Jfreeman Thanks for prompt reply, if have i more series than i need to hard code the values? if the value is changed instead of B or C to D or E in data base then i need modify the report again?
 
if you could have any generalized solution that helps more.
 
Thanks you.

Instead of using the series name you can use the seriesIndex.
For Example:
<pre class="_prettyXprint _lang-js">
beforeDrawDataPoint: function(point, pointOptions, chart, seriesIndex, pointIndex)
{
if(seriesIndex == 1){
pointOptions.dataLabels = {
y: -25
}
}else if(seriesIndex == 2){
pointOptions.dataLabels = {
y: -50
}
}
},
</pre>

Personally I think this is bad practice. What you are doing is changing the values displayed in the chart, which is misleading.

is there a similar solution to move label on a BarChart ?

JFreeman

What format of chart are you using (HTML5, SVG, PNG, etc.)?
 
In an HTML5 bar chart, the code should be quite similar to what I have already posted.

Hi Jesse,
 
the format is SVG , but i m working on a report that i didn't created, so i don't know if it s the best choice .
 
this reports are rendered in PDF , does it make any difference ?

JFreeman

The difference has to do with what scripting is required to make the change.
The SVG charts use different scripting than the HTML5 charts so the above code will not be applicable for your SVG chart.
 
If you are on open source birt, the SVG chart is probably your best choice.
If you are on professional, I may recommend looking into changing it to an HTML5 chart.
 
If you can provide a screenshot of the particular overlap issue you are facing with the SVG barchart, I can see about creating you a quick sample.
