To set the bar width on Bar Chart

jain

Hi, I have created a bar chart report, I want to set the width of the bar in inches dynamically based on the number of bars. So I have set the bar width in beforeGeneration method using chart.setUnitSpacing(), but the bar width is not exactly matching, have following questions: 1. In which unit do I need to set the unit spacing (either in points/pixels/inches)?
2. How to set the width of the bar in inches?

When using setWidth() it's expecting an integer for pixels. If you want to adjust the width of the bars you could use a some script like this.<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>function beforeGeneration( chart, context )
{
chart.setUnitSpacing(50);
}
var oldSpacing;
function beforeDrawSeries( series, seriesRenderer, context )

{
oldSpacing = context.getChartInstance().getUnitSpacing();
if( series.getSeriesIdentifier() == "series one" ){
context.getChartInstance().setUnitSpacing(70);
}
}

function afterDrawSeries( series, seriesRenderer, context )
{
context.getChartInstance().setUnitSpacing(oldSpacing);
}</pre>
<br />
<br />
This part chart.setUnitSpacing(50); is what you would change to increase or decrease the size of the bars. 0 being the bars touching and the higher you go the smaller they get.
