Re: [libreoffice-users] Fw: Help request on CALC charts' features

Hi :)
Draw also has some sort of layers function but i'm not sure they are as easy to use as Gimp.  Gimp 
is excellent but  keeping the chart in LibreOffice increases the chance of keeping the information 
dynamic rather than as a series of static files.  

Lamp uses MySql (sadly i've not heard of anyone using the non-Oracle drop-in replacement called 
MariaDb) which is a database back-end.  Could that pull in the data you use but do it automatically 
and dynamically rather than as snapshots?  Base can supposedly read and present the  data stored in 
MySql/MariaDb databases.  Other modules, such as Writer, can use various "data sources", i think 
the F4 key.  Can Draw?  Can Base use the original data rather than trying to pull the data into a 
MySql databse?

All that sounds like a complete nightmare to organise but i've already been very impressed with how 
fast you've managed to pick up new tools and get them doing something intriguingly unusual.  
Getting good-enough results fast is great.  

There might be a copyright issue with using Yahoo's data but presumably they get it their original 
data from a public source and then maybe do a few actions to the data to present it differently?  
Can you get to the original source and do your own set of calculations or do you have permission to 
use Yahoo;s info or is that not a concern at the moment?  (prolly best NOT to answer those.  It's 
just something to consider)
Regards from
Tom :)

Hi :)

I was able to overlap two charts in gimp as well as calc. Hurrraahhhh :)

* Adjusted axis on both charts - major, minor ticks to match each other. 

* Scales (rather everything) "Automatic"  is unmarked - in case we need to scale data ranges later.

* Made the top one completely transparent before moving on top of first. 


In gimp one can be sure that they don't "slide" - ever.

Not sure if there is a facility for that in calc - don't really expect. 

Just pinging in case anyone has any ideas. 

Objects once placed may move - e.g. one justified left other to center etc. - on their own
with some remote change elsewhere in the sheet.


The charts are now 100 times more helpful. No kidding!

Thanks a lot to everybody who chipped in with their suggestions.

 
Regards,
Viral Orpe :)

Hi :)


I have added the Yahoo finance image illustrating the overlap of the basic 

candlestick chart and line chart and bar chart to my facebook page.
Album: LibreCALC_Query
File: z.png


Hope that clarifies. 
 
Thanks,

Viral Orpe :)

Hi rost52 :)

Yes, That's right.
That is the one I am using. 

Problem is: 
I want to add some indicators on it too. 
Like say the average of the past 3 months - which will be a line chart.  

I have uploaded two screenshots (.png) of the file I am using on my facebook page. 
They are made "public" under the album "Libre_CALC_Query"
I don't use fb often so if you find any trouble downloading them please do not
fight with FB. Just let me know. In all probability it will be some mistake from my side. 

I might make it three screen-shots with one example from yahoo finance in a couple of hours.
Got to move out of this chair now!!!:)


Thanks,
Regards,
Viral Orpe :)

Candlestick charts

The wikipedia link was helpful.
I think that what you want to use is called in Calc chart type "stock". There are 4 different sub 
type shown. The second from left looks very much like the chart in the wiki link.
