Hi,

Sometimes when there is no data, the chart shows "no Data to display" still the export of chart works and it gives a blank image.

is there a way to check if the chart has given " no data to display" error and stop export?

Regards,
Cheiro

Hi,

Please find the attached screen shots of chart export and code...

the page renders chart using below here the xml has no data... intentionally

 protected void Page_Load(object sender, EventArgs e)
  	{
       		Literal1.Text = FusionCharts.RenderChart("../FusionCharts/Column3D.swf", "../FusionCharts/SaveDataEmpty.xml", "", "myFirst", "600", "300", false, true);
  	}

The xml is like so... the data inside is intentionally commented to simulate no data

<chart exportEnabled='1' exportAction='Save' exportAtClient='0' exportHandler='../Export_Handler/FCExporter.aspx'
caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' showValues='0' formatNumberScale='0' showBorder='1' >
  <!--<set label='Jan' value='462' />
  <set label='Feb' value='857' />
  <set label='Mar' value='671' />
  <set label='Apr' value='494' />
  <set label='May' value='761' />
  <set label='Jun' value='960' />
  <set label='Jul' value='629' />
  <set label='Aug' value='622' />
  <set label='Sep' value='376' />
  <set label='Oct' value='494' />
  <set label='Nov' value='761' />
  <set label='Dec' value='960' />-->
</chart>

Even if the chart shows no data, it allows it to export which results in generation of a blank image.
