BIRT 2.1.2 Chart error

sgavriel

Hi

I am using BIRT 2.1.2 and I am trying to create a report for Maximo v7.
While trying to setup the chart and I am inserting values from my data set in the X Series, Y Series and Y Series Grouping of the chart I get the following error (The chart id # varies depending on the combination of the expressions in the X and Y Series):

In the Y Series I may put something like: row["STATUS"]=="NEW" || row["STATUS"]=="INPROG"

and in the X Series I may put: row["SITEID"]

Chart (id = 289):
- The dataset used by the Chart is invalid
exception.unknown.datatype ( 1 time(s) )

Sometime I also get this error message:

"Unable to use a text data to render a numerical/datetime axis."

Can you please advise what needs to be done in order to successfully create a chart within the report?

Thanks,

Hi,

Regarding the first error i need more input. I am not clear what you were trying to do.

Regarding the second error "Unable to use a text data to render a numerical/datetime axis", This occurs when you define that the type of value that you pass to an axis is a text but you actually pass a date or a number.

This can be changed at double click the chart and go to the chart properties -> Format chart -> select Chart Area - >Axis

chek the type of value that you assigned for x axis and y axis.

You would have declared the type of an axis as "Text" but you pass a date or a number or decimal to that axis. So change it to DateTime type if the value that you pass is a date. If you pass a number or decimal you can choose the type as Linear or Logarithmic.

Thnx

So if I want to have in the
Value (Y) Series the row["STATUS"]
and in the
Category (X) Series the row["SITEID"]
and in the Optional Y Series Grouping the row["LOCATION"]

what should the each respective Axis type be?

I have tried the combinations and I still get the same error:
"The value axis may only have a numerical or datetime format"

Thanks

Hi sgavriel,

The Y-axis needs a number to do something with like Count, Sum, etc. For your example, after dragging SITEID to the X-Axis, press the grouping/sorting button, enable grouping, and then select COUNT for the aggregrate expression. Once you have done this you can put non-numeric values for the Y-axis since it is just counting them.

I created an example (with BIRT 2.3.2) that groups values by Country, City, and then Status.

UPDATE: I realized after I submitted this that you were using 2.1.2 so you wont be able to open this example. In my example, I selected CITY for the X-axis, turned on grouping, selecting Text, 1, and COUNT. Then I selected COUNTRY for the Optional Grouping. In then created 6 different series and on each series, I added an expression like:
SERIES1: if (row["STATUS"] == "Shipped") 1
SERIES2: if (row["STATUS"] == "Cancelled") 1,
etc.
... then rename the Series1, Series2, etc on the format tab, Series -> Titles

Can you just attach the rptdesign file if possible?.

Thanks a lot vdodson.
Your suggestions worked out great!!!
I selected SITEID for the X-Axis, turned on grouping, selecting Text, 1, and COUNT. Then I selected LOCATION for the Optional Grouping. Then I selected for the Value (Y) Series the following: row["STATUS"] == "NEW" || row["STATUS"] == "QUEUED" || row["STATUS"] == "PENDING" || row["STATUS"] == "INPROG"
