Custom error message

[bhalperin]

I have an ASP.Net applications and a Http Handler (.ashx) file that generates XML for a chart. This .ashx file is the dataURL attribute of the chart file. I'm using JavaScript to create the chat object and call the .ashx file.

The ashx handler is doing some work including retrieveing data from a database and constructs the XML string eventually returned.

If there is a failure while the ashx does its job, for instance failing to contact the database, I would like the .ashx handler to return an XML string to the JavaScript caller so it will be displayed inside the frame allocated for the chart, just like the default message "Error in loading data" is displayed at times.

Does FC include and attribute to the <graph> element that can do that? For example:

<graph errmsg="My custom error message"... >

hi,

you need to pass the error message as a message variable to the chart.

say, ...Column3D.swf?LoadDataErrorText=your message.

To knnow more on these message variables please visit see DOCS in http://www.fusioncharts.com/docs/Contents/ChartMessages.html

It would be great to be able to insert a ChartNoDataText custom message in the XML.

 

 

 

When the user change the state of a graph and there is no data, we could send a specific message on why this is happening instead of the generic one ("No data to display" or a personalized version).

 

 

 

Even if we use the JS event (FC_NoDataToDisplay), we still can

Hello,

 

 

 

This feature is not supported as of now.

 

 

 

However, could you please consider displaying an alert message in the suitable event raised by the chart?

I hope this helps.

Hi Rajroop,

 

 

 

when the JS event FC_NoDataToDisplay fires, I have no clue why there is no data because nothing is passed back to the function except the chart id.

 

 

 

I see 2 possibilities to solve this and they could be used both:

 

 

 

- allow the ChartNoDataText to be set in the XML

 

- allow a "JSparam" element to be set in the XML that would be passed back to the JS events. This element could contains a string of text or JSON that the function could use to customize his behavior on the fly.
