Hi All,

I need to create a horizontal bar chart in oracle APEX.In it i need to show payments on x axis and companies on y Axis.it is very easy to plot such horizontal bar charts.But now reuirements have become complex and now i need to show 12 horizontal lines for each company showing payments for each month of the year.

put each month in its own series

January would look like this...

select null,company,sum(payment_amount) payments from your_table
where payment_time >= trunc(sysdate,'yyyy')
and payment_time < add_months(trunc(sysdate,'yyyy'),1)
group by company
order by company

February would look like this...

select null,company,sum(payment_amount) payments from your_table
where payment_time >= add_months(trunc(sysdate,'yyyy'),1)
and payment_time < add_months(trunc(sysdate,'yyyy'),2)
group by company
order by company

then just increment the add_months  amount for each of the other series queries

hi,

Thanks for such a detailed explanation.I think the below chart will work for me:

http://anychart.com/products/anychart/gallery/sample_43.html

Also in my code i am putting year in where condition and i have extracted month and year from date in two separate coloumns.So please let me know what i need to write in my case.

because in this chart on y axis there will be company names in place of p1,p2,p3.......

and  there will be 12 series for each corresponding company value.Now will you please guide me how i can make this chart.Also i need to show in the right hand side the month with the color mentioned.

This may be very easy but i am working on Apex first time that's why i am asking such simple questiond.

Once again thanks for your valuable reply.

Regards,
Shyam

so you have two columns of numbers like this?

Year    Month
2000      1
2000      2
2001      2
2001      6
2002      3
2002      12

If so, your queries become easier

where year = to_number(to_char(sysdate,'yyyy'))
and month = 1 -- or 2 or 3 or 4 etc

if you have a year field that users can select rather than using current year

just put that in instead of "to_char(sysdate,'yyyy')"

you will still have 12 series though,  one series for each month

your legend will be based on the column name of chart data


select null,company,sum(payment_amount) january from your_table
where year = to_number(to_char(sysdate,'yyyy'))
and month = 1
group by company
order by company

select null,company,sum(payment_amount) february from your_table
where year = to_number(to_char(sysdate,'yyyy'))
and month = 2
group by company
order by company

Hi sdstuber,

Thanks for your help.I have done my job by your guidance.You have given a perfect solution.Thanks A lot.

Now i will ask another question related to hyperlinking the coloumns items in reports and by clicking on them user navigates to another page where the details behind that number appears.I will ask this question separately.Please help in that also.

Once again thanks alot.

Thanks
