ECU Toolkit - Change x-axis values of characteristic

Hello all,
I would like to ask for help with ECU toolkit. I establish communication with ECU (CCP), send in and out characteristics/measurements. Now I need to send special type of characteristic - Curve (1D). I use MC Characteristic Write.vi to change Z-values and MC Set Property.vi (Char X axis) to change X-axis values. As you can see on the picture, Z-values are changed, but X-axis values are not changed by this way (second column).
Does anybody know what is the problem or how to change x-axis values?
Thanks.

Hello Petr,
this depends strongly on what the ECU supports. The Characteristics (i.e. the Z axis) is always changeable, that's why it is a characteristics.
The corresponding axis might be fixed (i.e. be a simple array of fixed values), then the axis is read-only and you can't change it. However there are cases where the axis values can be written on the ECU... then the SetProperty(X-Axis) should work. There are also cases where the axis is not settable as axis, but there exists a different characteristics which contains the axis values, and this one is changeable. It depends pretty much on what is implemented in the ECU.
You might want to contact the supplier of the ECU to clarify this issue.
Hope this helps,
Christian

Unable to change X-axis values in playback

I need help with an issue in SignalExpress which I am new to
and struggling a bit.
In PlayBack mode DisplayView I can’t get the X-Axis to
retain the values I set. I can change them but as soon as I click ‘play’ the
max value alters to what appears to be the buffer length of the recorded data,
the on screen, AutoScale is off. The play-position indicator shows that I have
more data than one buffer length and exporting the log file to Excel confirms
that all the data (greater than one buffer in length) is there.
Regards
ed

My Mike,
Thanks for replying and giving suggestions.
I don't have Labview but could get evaluation version if you think this might help. I would be even less familiar with this than SignalExpress so the effort might not be worth it.
I have tried pre and post saving to set the x-axis, the results are the same. It looks like the values I set in the x-axis are overwritten by values within or associtaed with the recorded/saved file and I feel I must be missing something simple. I tried the help function and as far as I'm aware I'm following the information necessary.
What I do is set signal express to playback mode and in dataview having dragged my voltage logged file to the graph I right click and select 'properties' - 'scales'. for the 'time' option I uncheck autoscale andalter the max value to 300 ( I have 300 sec of recorded data) and click 'ok'. My data view graph changes x-axis to 300 max and a small ammount of data is compressed at the left hand side of the graph. I then click play at the top and the x-axis changes to 10 sec. The bar at the top shows 300s and scrolls though with what apperas to be just evry 10s of data (block) being displayed on the main graph.
If I then check 'properites' for the x-axis as above, auto sclae is still unchecked and max value reads 9.9s. I can change this and the graph x-axis changes until the next block gets placed on the screen where the x-axis reverts to 10s. After I make this change my data of unkown block gets compressed to the first 10s at the left, it fills the graph once updtae occurs but only the current (I assune) block.
if I look at 'playback options' I see nice little images of my data over 300s with start time 0 stop time 300 relative to log start time, block size 1000, overlap 0%, ignore last itteration if partial is checked and play entire intervals only is not checked.
I set the record side up for sampling 100Hz with block size 1000.
Hope this information helps you understand what is going on and that you can tell me what I've missed.
Kind regards

How to change axis values in Numbers

In v1.7 I have tried to change the axis values on existing charts but can't find how to do it...
So I tried to create bar charts from scratch in order to rebuild the old ones with the new axis data but I can't find out how to set any of the axis values on chart creation now!!
Has something changed - or am I just thick/blind?!!

Is it so difficult to read given answers ?
Barry described the correct scheme.
In the table "to_chart", the cell A1 contains :
=ROUNDUP(ABS(MIN(Tableau 1 :: B:E))/10,0)*10
The cell B2 embed the formula :
=$A$1+Tableau 1 :: B2
Apply fill down and fill to the right.
On the left edge, the colored rectangle is a text block in which I inserted the label values.
Of course if you dislike this scheme, you are perfectly free to use an other application.

How do you change the y axis value in numbers

Hi
relatively new to numbers. How do you alter axis value and set minimum, maximum values an step values in numbers
Cheers

Hi CA,
Did you really intend to post this Numbers question in the Pages forum?
Axis values are set in the Axis section of the Chart Inspector:
Select the chart.
Default values are 4 steps and auto settings from data for the min and max values for each axis. The x axis is a Value axis only for a scatter chart. Otherwise it is a Category axis.
To set Min, Max values and number of steps for either axis, click in the appropriate box, then either type the value or use the stepper (which apears) to step to your chosen value.
The maximum number of steps is 10.
Regards,
Barry

Excel MSGraph Axis Value w/ Report Gentration Tool kit help needed

Hello,
I am working on making all my Printed Data sheets dynamic so I don't need to have an Excel Template for each test I create. I have been able to make my own modifications to some of the Report Generation tool kit VIs to add little things I need or want changed, but I am stuck.
I currently have LabVIEW writing Charts in Excel, using the Insert Graph VIs from the tool kit but I want to be able to make the X Axis Values invisible but leave the Y values for this particular data sheet. I have looked through all my documentation but cannot find anything referring to setting that.
What is the correct ActiveX Method and/or Property that I need to incorporate to do this? I found that in Excel if I click on the Chart it is in the Chart Options Menu but I cannot find a way to control it through LabVIEW.
I am currently using 7.1.1 with Office 98 and the Report Generation Toolkit 1.1.0
Any ideas?
Thanks
Jeff

Hello,
LabVIEW should have access to everything that the excel ActiveX object publishes. One way to discover how to do it would be to record a macro in excel, where your recorded actions are on the x-axis as you desire. This way you will have a macro which you can run that will do this for you. Perhpas more importantly, you will then be able to look at the code for that macro you recorded, and make the equivalent calls in LabVIEW, which should basically expose which ActiveX calls on that object achieve the axis modification. In any event, to help you with this process, below are some useful links. Also, you will find other threads on this matter if you search the discussion forums.

Can't change string variable values in Flash CS4 Debugger

I'm using the Flash CS4 debugger, and while I can change numeric variable values in the Variables panel, I can't change string variable values. The only characters the fields accept are the numbers 1-9 and the characters "d" and "j".
I can paste strings into the value fields, but that's a bit of a pain. I've tried this on a couple of different Flash CS4 installations and get the same results.
Does anyone know if it's possible to change string values in the Variables panel of the Flash CS4 Debugger?

How do I update the chart axis values??

I created a Gantt (bar chart) chart in Numbers for a project at work showing schedules. It looked fine, and everything worked great. I want to use that same chart, but I want to just update the data in it. I can get the bars to change, but the Y axis data (not the numbered values in the chart, but rather the the actual names out to the side of the chart) will not change. For instance....
Name
Start Date
Finish
Task 1
January 1, 2013
January 15, 2013
Task 2
February 1, 2013
February 15, 2013
The Tasks on the left will be the Y axis fields in a bar chart....and the dates will populate the graph. I've created my graph from this data and got it like I want it. Now let's say I want to simply change some things in the Name column:
Name
Start Date
Finish
New Task
January 1, 2013
January 15, 2013
Task 4
February 1, 2013
February 15, 2013
So without creating a new chart or anything, I just want to reflect the new names in my existing chart. In Excel, when you change the value data, it updates the chart and "it just works" . I'm wanting to use Numbers for this, and I feel like this is a simple thing that I'm just missing. Help!

Jerrold....thanks for the reply. While you didn't answer my question exactly (I know I was a bit vague), you did put me on the right path. I was trying to get the Category Axis values to change on the chart whenever I updated them in the table itself. I couldn't figure out why they weren't but I think I have now.
I noticed that in the Category Axis field (Inspector) it had the actual typed names of my tasks from the table instead of the cell locations. So...."Task 1" instead of "Table 1: C7". I cleared out all of the text in the Category Axis field, which removed it from the chart. then I just clicked on the fields in the table and it populated the Category Axis blank with the table/cell info instead of the text. So now when I update one of the fields, it updates the chart because it's pulling from the cell data every time.
I'm not really sure why Number, by default, enters the text into the Category Axis when making a chart instead of putting in the corresponding cell locations, but whatever. I got it working now and should be good to go going forward, thanks for your help.

Graph: Get Right Y-Axis value with GetGraphCursor

Hello,
I'm currently developing an application for a customer which contains data being evaluated in a graph control.
There are different scalings of data so I use the left y-axis for digital data and right x-axis for analog data.
Now I want to add an annotation marker with the current X and Y value being displayed, when the user clicks into the graph.
I use those two functions to determine the position and affected plot of the marker:
GetGraphCursor(tabHandle2, TABPANEL_2_GRAPH, 1, &x, &y);
GetGraphCursorIndex(tabHandle2, TABPANEL_2_GRAPH, 1, &plotHandle, &plotIndex);
Now this works fine for the left y-axis, but I can't seem to find a way to get the y-axis value of the right side plot.
I figure plotHandle and plotIndex should help me to get this data, but sadly I don't know how to use this information.

Ok to clarify:
I have a graph with plot values on the left and right y axis. Some plots use the left and some the right side.
On default there is no cursor in this graph. But I want to provide the option for the user to enable a cursor.
When the cursor is enabled it snaps on to the closest plot and an annotation shows the respective x and y values of the plot point.
The problem is, when the left y axis is active and the cursor snapped onto a right y axis plot, the displayed y value is wrong (since the left scale is used).
By left clicking into the graph, the user is able to snap the cursor onto another plot.
So the main problem is, when clicking on a plot, the active axis has to change according to the plots respective axis.
I can easily make this decision since the plot styles are different (left side is VAL_FAT_STEP, right side is VAL_FAT_LINE), but for the axis switch to take effect on the cursor, I would need to delete and add the cursor again. But in this process I lose positioning of the cursor and it snaps to a different plot again.

How to Change Graph Axis

hi all!
Does somebody know how to change the Axis of a BIBeans Graph in a JavaApplication? i want to change the dimension which appears in the graph with one of the page dimensions. is that possible? how?
greetz pm

1. You could use waveform chart and use the Property Node for changing X0.
2. You could use Waveform Grpah and actually wire in BOTH X & Y values.
3. You could use the Offset Proprty Node of the waveform graph, as shown in the attached vi.
Hope it helps!

Logarithmic plot breaks with change in minimum value

If I try to alter the Y-axis scale on a logarithmic line plot---specifically, if I change the minimum value in the inspector---the axis suddenly becomes dramatically wrong.
Try for example: create a column with values 20, 30, and 100. Select and choose a line graph from Charts. In the inspector, choose logarithmic in the Y-axis drop-down.
This should work well so far. Now, set the minimum Y-axis value to 10 instead of 1. If I do this, the graph points do not move, while the values on the Y-axis dramatically change; all the data points are now erroneously above the 100 line.
I don't get any bad behavior if I change the maximum value; only the minimum seems to break the graph. Does anyone else get the same misbehavior?

Hmm...
Change the following....and check..
itab_BAPICONDX-ITM_NUMBER = '10'.
itab_BAPICOND-COND_ST_NO = '31'.
itab_BAPICOND-COND_COUNT = '00'.
itab_BAPICONDX-COND_TYPE = 'ZST3'.
itab_BAPICONDX-UPDATEFLAG = 'X'.
itab_BAPICONDX-COND_VALUE = 'X'.
append itab_BAPICONDX.
"change the above to.....
ab_BAPICONDX-COND_TYPE = 'X'.
append itab_BAPICONDX.
The BAPICONDX.. should contain only X.. in the fields which you want to update.. try this change..and let us know if it works.
Also have a look at the FUNCTION MODULE DOCUMENTATION for this bapi in SM37.

BI-IP: Change of characteristic value in ABAP EXIT planning function

Hi
I have created a planning function of the type EXIT with reference data without blocks. In method IF_RSPLFA_SRVTYPE_IMP_EXEC_REF~EXECUTE I am going to implement my code.
Now, one of the purposes is to update the VALIDTO of an existing record. Is it possible to modify the characteristic values directly in C_TH_DATA (thus allowing me to just update the date directly on the record) or can I only append records?
Cheers!
/Karsten

Hi Larse,
Yes you can change directly your value in a record withou appending a new one,but still it will create 2 records in the delta buffer ready to be save to the cube.

hi,
use the set_attribute( ) method now to set the attribute with a particular key eg HIGH in ur case
// u can use the code wizard( control +f7) this code will be auto generated when u select the
//radio button to read the context node
DATA lo_nd_cn_node TYPE REF TO if_wd_context_node.
DATA lo_el_cn_node TYPE REF TO if_wd_context_element.
DATA ls_cn_node TYPE wd_this->element_cn_node.
* navigate from <CONTEXT> to <CN_NODE> via lead selection
lo_nd_cn_node = wd_context->get_child_node( name = wd_this->wdctx_cn_node ).
* get element via lead selection
lo_el_cn_node = lo_nd_cn_node->get_element( ).
* set single attribute
lo_el_cn_node->set_attribute(
name = `ATTribute name.`
value = 'LOW' ).
it will solve ur query ..
also refer to this component
wdr_test_events -> view dropdownbyidx and dropdownbykey ->method name onactionselect.

How to change the column value which is coming from DO by a calculated field?

Hi all,
I want to change a column value based on my calculated field value. I have a column which is coming from DO which is based on External Data Source. I have a calculated field in my report. When there is any change in the calculated field then the column which is coming from DO needs to be changed. It means the DO needs to get updated when there is a change in the calculated field. Or like if the calculated field meets some condition then I need to change/update the same in the DO. This has to be done on the fly. the report should not submitted for this. when there is a change in the calculated column the DO column needs to get updated.
Thanks,
Venky.
