To make Bar width constant in Chart

jain

Hi is it possible to keep the bar width constant? I have mapped the xaxis and yaxis of the bar chart to the dataset column.In my application,i dont know the number of items that will be shown in the bar chart ,after i run the chart.Number of items to be shown in the bar chart are random ,coming from my database.So if the item is 1,then the width of bar in the bar chart increases ,if the items are 10,then the width of bar in the bar chart decreases. I want to keep the bar width constant. So how can I do it?

You can set the width of the bars in the chart from script. <a class='bbc_url' href='http://www.birt-exchange.org/org/forum/index.php/topic/10428-change-width-of-bars-in-chart/page__s__85e70f48cff7d90d4f7e07abbe40ea7f'>Take a look at this post</a> You'd use something like<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>function beforeGeneration( chart, context )
{
chart.setUnitSpacing(20);
}
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>
