2 different Y scale.

Hi everyone, I have a strange problem, so I am able to use 2 scale in different (I have found the answer here in forum), but if I change the range of plot 0, the value of plot 1 is changed as well. And it's happened vice-versa. I don’t know why.
I have another problem. When I change the range, the gird is changed as well. How can I fix it?
Have you got any ideas?

I'm not sure what the code is doing. What exactly are the knobs setting? Clearly it's not the amplitude of the signals or the scales.

Create different y scale dynamicly on graph

hello all
I have a problem that, i need create many different y-scale in the graph, one method is right click the scale, select "Duplicate Scale"
then a new scale will be ok. however, this is just static method, before the VI running, the total of the y-scale is fix. Is there some dynamic method
by call property node to create the new y-scale when the VI is running? for example, if i do not know how many channel data to be acquired, then
i can not determine the total quantity of the y-scale, so if dynamic is ok, then , it is very perfect.
Every one suggetion is very appreciated.

We needed to do something similar becuase of a customer requirement. From what you said, if you know the maximum number of axis, create the maximum number of scales required by right clicking and duplicating scale. During runtime hide/unhide the scale as shown below.

Different x-scales

Hello,
I use one waveform chart. Can somebody tell me if it is possible to change the x-scale from the graph (Controls;Graph;Waveform Chart), so that you can switch between different time scales in this one Waveform by clicking a botton(s)? (week, month, year)
Thank you

What you can do is untick the autoscale from your X-scale and then dynamically adjust the range of the scale according to the button pressed.
See the VI attached as an example. Please do not take care of the presentation, I did it really quickly...
Hope this helps anyway !

Subsequent settlement with different volumes (scale and rebate)

Hi
A nice question for you all.
In subsequent settlement I want to do the following:
Interval scales:
>$100.000 -> 1% rebate
>$450.000 -> 2% rebate
>$600.000 -> 3% rebate
(this is easy)
When I want to determine the business volume I want to differentiate between:
- trucks
- cars
Based on the following numbers:
Annual business volume for trucks: $200.000
Annual business volume for cars: $300.000
Total volume: $500.000
This means the rebate wil fall in the 2% interval.
BUT.... the rebate is ONLY for cars and NOT for trucks.
--> 2% of 300.000 = $6.000
How to do this?
Regards,
Arno

Sangeeta,
What do you think of the following:
Build up business volume for every delivery of the supplier and also for the trucks.
I will make two rebates:
For the total volume:
>$100.000 -> -1% rebate
>$450.000 -> -2% rebate
>$600.000 -> -3% rebate
For the trucks volume:
>$100.000 -> +1% rebate
>$450.000 -> +2% rebate
>$600.000 -> +3% rebate
Since the trucks will be in the +1% rate and the total volume will be in the 2% rate I have to change the interval for the scales condition manually in trx MEU2, but not the price condition. After the comparisation is finished both are in the +/- 2% scale and I can settle the agreement.
Only one manual step needed, sounds as a fine solution, do you agree?

Is it possible to express two y axes on a xy graph with different scale

Is it possible to express two y axes on a xy graph with different scale
I need to program it... Please help me

Hello.
Yes, it is possible to have two different vertical scales on an xy graph. There is no way that I know of to add a scale programmatically, but once you have added it, you can configure the range of it programmatically, as well as assigning a plot to any particular scale. You do this by using an xy-graph property node, with the properties YScale.Minimum, YScale.Minimum, and Plot.YScaleIndex respectively.

XY Graph-Setting Y-Scale visible to False still Shows Corresponding Y scale Max and Min

Hi Guys,
I use XY graph to display the data with 3 Y-scales.
When I set any Y scale Visiblity property to False,its still display the Y scale Max and Min range Lines in plot area of the Graph and making cross line or extra parralel line with other visible scales.
Attached the screen shot for ref.
And I know the cross line may be due to different Y scales range setting.But XY graph should not display the invisible Y scales and its property as well.
please provide your suggestions to avoid that.
Solved!
Go to Solution.

The scales and the lines associated with those scales are separate properties. I have never tried it, and right now I am not at a computer, but there should be properties for setting the grid line colors. Set them to transparent.

Save custom scale while associated task is running

Hi,
I would like to know if it's possible to change the value of a custom scale while a task (using this scale) is running ?
If yes, when will the new coefficients be applied ?

On the deivices I used, you have to stop the task and restart it to apply a different custom scale.
Consider doing scalling "on the fly" with formula nodes, Polynomial Interpolation, lookup tables, or whatever works for your scale. This way, changing on the fly is easy.

How to set condition scale according to accumulated purchasing quantity?

Hi,
I want to set different condition scale for a material according to the accumulated purchase quantity against a vendor (includeing historical purchase order), just like follows:
Accumulated purchasing qty (including hostorical PO): 100 pcs ---> 1.5$/pc
Accumulated purchasing qty (including hostorical PO): 200 pcs ---> 1.4$/pc
Accumulated purchasing qty (including hostorical PO): 300 pcs ---> 1.3$/pc
Accumulated purchasing qty (including hostorical PO): 400 pcs ---> 1.2$/pc
Accumulated purchasing qty (including hostorical PO): 400 pcs ---> 1.1$/pc
So, how to realize this by standard functions?
Please kindly advise.
Thanks and best regards.

Hi, Sanjay,
Thank you very much for your answer.
But manybe I had not described my qustion more clear, my requirement is, to control the quanaity-based scale according to accumulated purchasing quantity including historical purchase order but no the one/individual purchase order.
So, please kindly advise again.
Thanks and best regards.

How to set condition scale according to accumulated consignment quantity?

Hello,
We have different consignment prices for the same material vendor depending on the quantity.
For example:
First 100 pcs -->1.5$/pc
Following 100 pcs -->1.4$/pc
Following 100 pcs --> 1.3$/pc
So, I want to set different condition scale for a material according to the accumulated quantity transferred from vendor consignment to own.
So, how to realize this by standard functions?
Everything that I have tried with the scale condition type in consignment info record only works with the quantity that I am transferring in that moment from consignment to own. Is there any anything that I can setup to take into account the accumulated quantity?
Please kindly advise.
Thanks and best regards.

Look at the Group Condition settings of your Condition Type. You'll need to some ABAP resource to create a Requirement.

How to see actual fonts while composing mail?

This is driving me crazy. I often copy and paste different bits of text from other sources into email messages I compose in Mail. When I paste in the text, it always appears to be in the same font and size as the existing text. Once I send the email, I discover, much to my chagrin, that the pasted text often shows up in a different font or style. This holds true even if I send an email to myself and read it in Mail. If it is just in a slightly different font it only looks a little sloppy, but it is very embarrassing when it is a radically different font or size.
Sometimes the errant font is applied to only fixed-width fonts, and I can fix it for my own display by setting my "fixed width font" and "message font" to the same thing. But this just makes it look better for me -- anyone else is still seeing the different fonts. And sometimes it happens with formatted text (i.e, pasting a line from a webpage where the text looks fine in the composed mail but shows as huge and bold when the mail is received).
I have my "composing - message format" preferences set to Rich Text, because I want to be able to send rich text messages. I have tried to train myself to use the "paste and match style" command, but I am so used to "command - v" that it is hard to remember to use "shift-option-command - v" every time.
If I change a font intentionally, using the format fonts palette, the different font is immediately visible in the compose window.
This happens on both my Macbook, not on my and my Mac Mini; they are each running Mail 3.6 and OS X 10.5.8
Any ideas? It is very frustrating.

Wish I could be king. But you described the problem perfectly and I am still but a pawn. All I can say is that I trashed the mail preferences (com.apple.mail.plist) on my Mac Mini, and now my MacBook seems to work right.
Sorry. :>) But that is the truth... The MacBook now has actually sometimes displayed pasted text in its actual, different, font and style as I paste it into a partially composed new mail message.
In other (more rational) words, the problem seems to be tied to pasting only certain types of text. I have not been able yet to pinpoint what. Yes, frustrating indeed. The only work-around has been to re-train my fingers to command-option-shift V, for "paste and match style" (like you, I do not want to always use only plain text). Maybe someone else will eventually weigh in with a real solution. The solution I want is just to be able to consistently see any font variations within my message before I send the email.
The info about the different ppi scales between Windows and Mac is interesting, although not relevant to this particular problem. It does explain the apparent overall size differences I have seen before.

Oracle Spatial Performance with 10-20.000 users

Does anyone have any experience when Oracle Spatial is used with say 20.000 concurrent users. I am not interested in MapViewer response time, but lets say there is:
- an app using 800 different tables each having an sdo_geometry column
- the app is configured with different tables visible on different view scales
- let's say an average of 40-50 tables is visible at any given time
- some tables will have only a few records, while other can hold millions.
- there is no client side caching
- clients can zoom in/out pan.
Anwers I am interested in:
- What sort of server would be required
- How can Oracle serve all that data (each Refresh renders the map and retrieves the data over the wire as there is no client side caching).
- What sort of network infrastructure would be required.
- Can clients connect to different servers and hence use load balancing or does Oracle have an automatic mechanism for that?
Thanks in advance,
Patrick

Patrick, et al.
There are lots of things one can do to improve performance in mapping environments because of a lot of the visualisation is based on "background" or read-only data. Here are some "tips":
1. Spatially sort read-only data.
This tip makes sure that data that is close to each other in space are next to each other on disk! Dan gave a good suggestion when he referenced Chapter 14, "Reorganize the Table Data to Minimize I/O" pp 580- 582, Pro Oracle Spatial. But just as easily one can create a table as select ... where sdo_filter() where the filtering object is an optimized rectangle across the whole of the dataset. (This is quite quick on 10g and above but much slower on earlier releases.)
When implementing this make sure that the created table is created such that its blocks are next to each other in the tablespace. (Consider tablespace defragmentation beforehand.) Also, if the data is READ ONLY set the PCTFREE to 0 in order to pack the data up into as small a number of blocks as possible.
2. Generalise data
Rendering spatial data can be expensive where the data is geometrically detailed (many vertices) esp where the data is being visualised at smaller scales than it was captured at. So, if your "zoom thresholds" allow 1:10,000 data to be used at 1:100,000 then you are going to have problems. Consider pre-generalising the data (see sdo_util.simplify) before deployment. You can add multiple columns to your base table to hold this data. Be careful with polygon data because generalising polygons that share boundaries will create gaps etc as the data is more generalised. Often it is better to export the data to a GIS which can maintain the boundary relationships when generalising (say via topological relationships).
Oracle's MapViewer has excellent on-the-fly generalisation but here one needs to be careful. Application tier caching (cf Bryan's comments) can help here a lot.
3. Don't draw data that is sub-pixel.
As one zooms out objects become smaller and smaller until they reach a point where the whole object can be drawn within a single pixel. If you have control over your map visualisation application you might want to consider setting the SDO_FILTER parameter "min_resolution" flag dynamically so that its value is the same as the number of meters / pixel (eg min_resolution=10). If this is set Oracle Spatial will only include spatial objects in the returned search set if one side of a geometry's MBR is greater than or equal to this value. Thus any geometries smaller than a pixel will not be returned. Very useful for large scale data being drawn at small scales and for which no selection (eg identify) is required. With Oracle MapViewer this behaviour can be set via the generalized_pixels parameter.
3. SDO_TOLERANCE, Clean Data
If you are querying data other than via MBR (eg find all land parcels that touch each other) then make sure that your sdo_tolerance values are appropriate. I have seen sites where data captured to 1cm had an sdo_tolerance value set to a millionth of a meter!
A corollary to this is make sure that all your data passes validation at the chosen sdo_tolerance value before deploying to visualisation. Run sdo_geom.validate_geometry()/validate_layer()...
4. Rtree Spatial Indexing
At 10g and above lots of great work went in to the RTree indexing. So, make sure you are using RTrees and not QuadTrees. Also, many GIS applications create sub-optimal RTrees by not using the additional parameters available at 10g and above.
4.1 If your table/column sdo_geometry data contains only points, lines or polygons then let the RTree indexer know (via layer_gtype) as it can implement certain optimizations based on this knowledge.
4.2 With 10g you can set the RTree's spatial index data block use via sdo_pct_free. Consider setting this parameter to 0 if the table/column sdo_geometry data is read only.
4.3 If a table/column is in high demand (eg it is the most commonly used table in all visualisations) you can consider loading (a part of) the RTree index into memory. Now, with the RTree indexing, the sdo_non_leaf_tbl=true parameter will split the RTree index into its leaf (contains actual rowid reference) and non-leaf (the tree built on the leaves) components. Most RTrees are built without this so only the MDRT*** secondary tables are built. But if sdo_non_leaf_tbl is set to true you will see the creation of an additional MDNT*** secondary table (for the non_leaf part of the rtree index). Now, if appropriate, the non_leaf table can be loaded into memory via the following:
ALTER TABLE MDNT*** STORAGE(BUFFER_AREA KEEP);
This is NOT a general panacea for all performance problems. One should investigate other options before embarking on this (cf Tom Kyte's books such as Expert Oracle Database Architecture, 9i and 10g Programming Techniques and Solutions.)
4.4 Don't forget to check your spatial index data quality regularly. Because many sites use GIS package GUI tools to create tables, load data and index them, there is a real tendency to not check what they have done or regularly monitor the objects. Check the SDO_RTREE_QUALITY column in USER_SDO_INDEX_METADATA and look for indexes with an SDO_RTREE_QUALITY setting that is > 2. If > 2 consider rebuilding or recreating the index.
5. The rendering engine.
Whatever rendering engine one uses make sure you try and understand fully what it can and cannot do. AutoDesk's MapGuide is an excellent product but I have seen it simply cache table/column data and never dynamically access it. Also, I have been at one site which was running Deegree and MapViewer and MapViewer was so fast in comparison to Deegree that I was called in to find out why. I discovered that Deegree was using SDO_RELATE(... ANYINTERACT ...) for all MBR queries while MapViewer was using SDO_FILTER. Just this difference was causing some queries to perform at < 10% of the speed of MapViewer!!!!
6. Consider "denormalising" data
There is an old adage in databases that is "normalise for edit, denormalise for performance". When we load spatial data we often get it from suppliers in a fairly flat or normalised form. In consort with spatial sorting, consider denormalising the data via aggregations based on a rendering attribute and some sort of spatial unit. For example, if you have 1 million points stored as single points in SDO_GEOMETRY.SDO_POINT which you want to render by a single attribute containing 20 values, consider aggregating the data using this attribute AND some sort of spatial BUCKET or BIN. So, consider using SDO_AGGR_UNION coupled with Spatial Analysis and Mining package functions to GROUP the data BY <<column_name>> and a set of spatial extents.
6. Tablespace use
Finally, talk to your DBA in order to find out how the oracle database's physical and logical storage is organised. Is a SAN being used or SAME arranged disk arrays? Knowing this you can organise your spatial data and indexes using more effective and efficient methods that will ensure greater scalability.
7. Network fetch
If your rendering engine (app server) and database are on separate machines you need to investigate what sort of fetch sizes are being used when returning data from queries to the middle-tier. Fetch sizes for attribute only data rows and rows containing spatial data can be, and normally are, radically different. Accepting the default settings for these sizes could be killing you (as could the sort_area_size of the Oracle session the application server has created on the database). For example I have been informed that MapInfo Pro uses a fixed value of 25 records per fetch when communicating with Oracle. I have done some testing to show that this value can be too small for certain types of spatial data. SQL Developer's GeoRaptor uses 100 which is generally better (but this one can modify this). Most programmers accept defaults for network properties when programming in ADO/ODBC/OLEDB/JDBC: just be careful as to what is being set here. (This is one of the great strengths of ArcSDE: its TCP/IP network transport is well written, tuneable and very efficient.)
8. Physical Format
Finally, while Oracle's excellent MapViewer requires data its spatial data to be in Oracle, other commercial rendering engines do not. So, consider using alternate, physical file formats that are more optimal for your rendering engine. For example, Google Earth Enterprise "compiles" all the source data into an optimal format which the server then serves to Google Earth Enterprise clients. Similarly, a shapefile on local disk to the application server (with spatial indexing) may be faster that storing the data back in Oracle on a database server that is being shared with other business databases (eg Oracle financials). If you don't like this approach and want to use Oracle only consider using a dedicated Oracle XE on the application server for the data that is read only and used in most of your generated maps eg contour or drainage data.
Just some things to think about.

Problem printing static images vs camera tool snapshots

Hi.
This question might be a matter of formatting instead of a developer question but since it is related to some VBA code I am using I thought it would be appropriate to post here. If it isn't, can someone let me know which forum would be more appropriate?
Here's the situation. I have a workbook that has many tables on separate worksheets. Then I have couple "summary" type of worksheets which contain camera tool snapshots of tables from different worksheets for easier viewing/printing.
Because of the heavy lag in recalculation time created by using camera tool snapshots, I have turned the snapshots into static images by removing the source range from their formula. Instead, after making whatever changes I need in the data, I use a
VBA macro to loop through each snapshot and briefly restore the source range formula so that it updates to reflect the latest table changes then clear the source range formula again, returning the snapshot to a static image. This seems to work fine when
I view the worksheets and makes the recalculation of the tables much faster when changing the data.
However, I have encountered a new problem. If I print the summary worksheets with the static images, each table is printed as smaller than when they are snapshots. In other words, when the source range formula is set to the appropriate range
and I print the sheet, everything looks fine. When I clear the source range formula and print the sheet, each table is now horizontally smaller and some information in the last column is being cut off. The images/snapshots have their size set to
100% of the original and I have tried keeping "Relative to the original" checked and unchecked with no difference. Does anyone know why this is happening?

It may not be the images. It may be the print options are set to auto scale the worksheet. Try manually printing a one test page and try different print scale options. Use Print Preview which will allow you to scale page sizes.
Often issues like this occur when you are trying to print more than one page at a time. The scale on one page may be different from a second page. Sometimes adding page breaks (horizontal and vertical) helps solves these issues.
