Changing the x axis

Hi everyone.
I have done an fft in lab view signal express, but the x axis shows the frequency (Hz).
I need it to show the range.
I have the formulae to change the x axis, but i am not sure on how this can be done!.
the formuale is range = freq *c*dT/(2*dF)
Where dT = 0.02
and dF = 66*10^6
c = 3*10*8.
how can i get the range on the x axis.
many thanks.

Right-click the graph and select Properties.
Then go to the Scales tab.
The drop down box shows by default the X-axis, so that's ok
If you need another scale, select it first.
On the same tab you also see Scaling factors Offset & Multiplier.
Calculate both to convert what you have now to what you want
I won't do the math's for you
Enter the two values and
Then click the Ok button.

Change the x axis scale markers in a waveform graph

Hello all,
I am looking at an unusual graphing problem that hopefully has been solved. The problem is because an pre-existing DAQ graph does things in a chart-like manner.
The application context is that I measure a signal vs. test length. During the test, I calculate the UUT position as a function of the test length. The test includes measurements out and back. Rather than graph signal vs. length; I want to graph signal vs. position. I have considered the XY graph, but that co-locates the position data. To remain consistent with an existing test program, I want to change the X Axis marker labels from distance to position at each marker's distance.
I would like to customize marker text for a waveform graph's X Axis. I found a sub-property node for marker text, but it does not seem to iterate through a Waveform graph's X Axis markers.
For example, a test measures the distance 0 to 200 and the X Axis markers are labeled {0, 50, 100, 150, 200}. How do I change those labels to {0, 50, 100, 50, 0}?
The Marker Values[] property node does not do what I expected.
Thanks,
Kenneth
Possible solutions:
1. Find a property node that does the job
2. Use custom indicators for each marker's labels
3. Use two graphs, one for forward, the other for reverse testing
4. XControls

For your option #4 I would use option #2 but use a single picture and hide the X-Axis and do my own.

Change the x-axis series in excel chart

Hi,
While plotting an Excel chart using ExcelRpt_ChartWizard(), the x - axis series starts from 0, 1, 2, 3... I like to change the series according to the data present in a particular column. Eg. If column 2 contains 2, 5, 7, 6.2... then the x-axis should be in the order 2, 5, 7, 6.2.....
Can anyone help me regarding this issue?

Hi,
Many thanks for this post, It's been quite helpful since there seems no to be so much info available about not so basic generation and manipulation of excels graphs with LabWindows (at least compared to C#).
I am struggling to set my own X-Axis as well but the best I can get is the graph looking like the one of the attached file.
The first row for the X-Axis is 11:47:00 and the last one is 17:46:25, however I get a graph between 0:00:00 and 19:12:00.
May thanks,
Best regards

Changing the x-axis crossing point on a log y-axis

Is it possible to change the point at which the x-axis crossing a log y-axis?
I'd like the origin to be 0.1, not 1, and I'm losing hours of my life trying to work out how to do it.
Hopefully it will be something easy that I have missed...
...I'd rather look foolish than buy Microsoft office.

I have another idea for you.
1) Multiply all of your numbers by 10 or whatever factor of 10 (i.e., 100 , 1000, etc.) is necessary so that none of them are smaller than 1.
2) Take the LOG of those new numbers.
3) Plot the result of (2) using a linear Y axis. Get your chart looking like you want it with the min, max, and number of Y axis gridlines you want. Each number on the Y axis needs to be an integer, no decimals.
4) Choose a custom format for the Y axis numbers. Delete the format that is there and add a new format for each of the numbers on the axis. For example, lets say you multiplied by 100 in the first step above. The gridline with the number "0" should really be "0.01" so make a format for "if value is 0" and type in 0.01 as the format. Repeat for the other numbers (1 becomes 0.1, 2 becomes 1, 3 becomes 10 ,etc).
Again, kind of a pain. I think I like this solution better, though. The chart looks better in the end and you can do multiple data series on the same chart.

How to change the Y-axis scale for 100% stacked column to percentage ?

Hi,
I add a 100% stacked column chart to a report in Crystal Report for Enterprise. As default, the Y-axis scale shows value from 0 to 1 and the data labels display absoluted data value. Now I want the Y-axis scale to show value from 0% to 100% and the data labels to display percentage value.
Please tell me which option of the chart to adjust ?
Thanks
Mau Vu Huu
The default is like screenshot below:
I want it to display as screenshot below:
thanks
Mau Vu Huu

Looks like a bug in CR for Enterprise.
The same chart shows a scale from 0% to 100% in the CR 2011 designer whereas CR for Enterprise seems to show a number range from 0 to 1.
Here's a workaround:
1) Insert a Crosstab. 'Column' should be the field you wish to show on the 'X-axis'. 'Row' should be the field that you wish to stack up on the bars. Summary should be the measure field
2) Next, right-click one of the summary cells on the Crosstab > Select Format Total > Total > Check 'Show as Percentage of' > Grand Total > Row
3) Right-click the Crosstab > Select Create Chart from Crosstab Data
4) Suppress the section that holds the Crosstab
5) Right-click the chart > Edit Chart Type > Choose 'Stacked Column'
6) Highlight one of the numbers of the Y-axis > Select Format Total (Y) axis > Format > Currency > Choose 'Fixed' under 'Symbol Format' > Replace '$' under Symbol to '%' > Change Symbol Position to '-123$'.

How can I change the X-axis increment in a waveformgraph

The X-axis always increments by 1, but I am acquiring one point of data every 100 ms. So my chart moves 10 times fater that the real time. How can I set my x-axis to increment 0.1 every time I add data to my Waveformgraph in VB net?
The X-axis collection is not showing any property to change that.
I have a continuous data acquisition giving me timed data at 100 ms rate.

Thank you for posting to the NI forums. You can set the update increment of the WaveformGraph plot function by using the overloaded function as follows:
PlotYAppendMultiple( ByVal yData As Double(,),
ByVal orientation As DataOrientation,
ByVal increment As Double )
I did this in the VB.NET example program, "ContAcqVoltageSamples_IntClk", by adding the following line to the dataToDataTable function.
WaveformGraph1.PlotYAppendMultiple(sourceArray, NationalInstruments.UI.DataOrientation.DataInRows, 0.1)
The increment will be set to 1 / (sampling frequency), so in your case, it will be set to 0.1. This function is documented in the NI-DAQmx .NET Framework 2.0 Help.
I hope this helps. Post back if you have any further questions.

Changing the chart axis step

Hi all,
i have a chart with some dates in axis X, values of money in axis Y. My dates not having the same step. Example: 01/10/2008, 01/11/2008, 02/25/2008, 03/01/2008 etc...
I need to change the step of my axis X (like a day) for having spaces between dates proportional to delta time.
How I can alter the step of my axis X?
Thank you all.

You'll have to union on a query that returns all dates and a zero measure (or you could try null) but it isn't very pretty. Rumor has it a future edition of OBIEE will be 'continuous time aware' ...

To change the X-axis from Samples to Time

Hi All,
I want to connvert the X axis from Samples to Time on my waveform graph. The waveform graph displays the number of samples acquired along X axis, Initially I am acuiring 1M points of data & using some algorithm to reduce the number of samples from 1M to 2K points. Even after reduction I'm able to see the entire record length of the waveform but interms of 2K samples. But I want the X axis to be displayed in Time.Is it possible to convert the X axis of my graph to Time as there is reduction in points from 1M to 2K or the reduction doesnot affect the change in axis from samples to Time. Please help me as I have tried every thing.
Thanks

You can get some information on the waveform data type in the on-line help by selecting the data types>default values topic. This will also point you to the LabVIEW User Manual and the LabVIEW Measurements Manual. Both of these manuals are part of the LabVIEW documentation installation. You have an entire palette called, appropriately, Waveform, for manipulating the data and the front panel control is on the I/O palette.
One of the options when doing, for example data acquisition, is the type of data returned with a DAQmx Read or AI Read. For DAQmx Read, click the Polymorphic VI Selector below the function to change the type of data returned. a large number of the shipping examples for DAQmx use the waveform data type. Selecting or creating a waveform data type is the easiest way to pass time information to your chart or graph but it is not the only way. You can use a property node like the shipping example called Real-Time Chart.

How can I change the Y axis to show my values in a descending order in Numbers. eg zero at the top and the maximum value at bottom?

Hi,
I'm just about getting to grips with Numbers, but I'm stumped at the moment with this problem.
I want to show zero at the top on the (y) axis, as zero is the goal and 100 is the starting point?
can it be done? i would really appreicate some help on this.
Kind regards

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

How can I change the Y-axis (circular) grid spacing, in Polar Plot VI?

When using Polar Plot VI, I need more control over the plotting parameters. This means tweaking the sub-VIs in various ways. What I need to do most is make the polar magnitude axis less busy, i.e. only draw circles every 10 instead of every 5 divisions, when using a range of 0 (outermost) to -80 (innermost).
The magic 'magnitude axis subdivisions' variable seems to be generated in Calc Scale Specs sub-VI, and output as an array of clusters, but I can't quite see how it's created and from what.
Please can anyone help me gain control over the number of magnitude division circles generated?
Many thanks!

I think if you go inside the Calc Increment.vi and modify the Increment output terminal it might change what you want to see. Try putting a multiply by 5 or ten into the case structure for when the log is false.

Visual Composer 7.0-Change the Y-axis from decimal scale value to integer

Hi Experts,
I'm new in Visual Composer 7.0, my report is work fine, but when I want to show the data in bar-chart, the values on y-axis are 0.0, 0.4.0.8,1.2,1.6.2.0 but i want like 1,2,3,4.
Normally, this happen when values on y-axis less than 5, if more than 5, it will turn to 1,2,3,4. (which i expected)
Inside my function module, I set all the data as integer already..
I read through some suggestions in the forum, they suggest using 'Fixed range' and set the interval size, but need to include min & max value. But, inside my program, min value & max value has to be automatically adjusted, ie i can not set the values for those.
Please suggest solution for me, need it urgently..
Thanks a lot!
Best regards,
Derrick

Hi,
first of all: please close this post. It is definitely the wrong forum. Your second thread regarding this is in the right forum.

Hi All,
I'm sorry but this seems to me impossible to do.
In general - not necessarily for this case - there is the option to create your own Flash Components and integrate them into VC, so you could overcome such limitations.

Is there a way to change the time of a saved data to be as the same as the time-axis of the waveform graph?

Hi,
I've a problem while saving the waveform to a spreadsheet.
The problem that I'm facing is that I'm not able to save/change the time-axis of the waveform graph into the excel spreadsheet.
The attachments below are what I've programmed on.
1st file that would be asked to save is the results of the waveform.
2nd file, supposing to be the time-axis
3rd file, is the multiplication of results of CH 1 and CH 2.
Would be glad if someone can enlighten me with a solution which is suitable for LabView version 8.2 and Tektronix DPO 72004.
Thanks. ((((:
