Hi,
I am a new user to Eclipse and BIRT. I tried building a simple listing
report
following the Tutorial 1 : Building a simple listing report of BIRT
developer
guide. I was able to succeed in that.
Next, I tried creating a basic chart folowing the BIRT developer guide. As
I
did not have a database at that time I created a flat file data source for
which I created a .csv file containing Year, City and Population similar
to the
table in the "Creating a basic chart" of BIRT developer guide.
I created the data set using the flat file data source name and I selected
the
3 columns (i.e Year, City and Population) and I previewed the results. The
table was fetched and the data values were displayed. Then bar chart
element was inserted, specified the data set, specified the sample data
given in the guide for the bar chart using a y series grouping key as per
the guide. The chart design appeared in the layout similar to the one
given in the guide.
Next when I clicked preview an error message like
There are errors on the report page:
Error1:Failed to render Chart
Unable to compute a percent/stacked axis containing non-numerical data
could anyone help me in this regard
Thanks in advance

Greeting,
If you selected the 1st (stacked) or 2nd (percent stacked) subtype of bar
chart, please make sure that the data type of row["Population"] is numeric.
Cheers.
Regards,
Nina

Hi,
But how to make the datatype of row["Population"] as numeric via the chart
dialog.
In the output columns of Edit data set dialog box the data type of
Population is String. I think what u are trying to convey is to change the
datatype by there itself. But could you help me in this regard
Thanks in advance
Cheers
