Hold on previous plots XY Graph?

Hi everybody,
I am a new user of LabVIEW7. Everytime I generate a plot on the XY graph, the previous is erased, I would need to hold on the previous plots on the XY Graph. Can somebody tell me wheter it is possible please?
Thanks.

How to plot waterfall graph in vb6 from offline data

How to plot waterfall graph in vb6 from offline data?The data load from SQL Server Database.Thanks.

asrol,
If you look at the Plot Styles example in the folder I mentioned in the previous post there is a section of code there that you might want to refer to in order to recreate your data.
'=============================================================================
' Plot Curve Button Handler
'=============================================================================
Private Sub PlotCurve_Click()
    ' Create curve data
    Dim x(40)
    Dim y(40)
    Dim z(40)
    For i = 0 To 40
        x(i) = Sin(i / 3#)
        y(i) = Cos(i / 3#)
        z(i) = i
    Next i
In this example they create 3 arrays to represent the three dimensions of the array. For your case if you were to plug your data into two of the array (axes) that would give you the data for the channels, then you can simply input a constant for the third array it would produce a single line of your data as shown in your example GIF. You can then repeat this process for each set of data, with a new constant value for that third axis, and it should manually create a graph that will look something like you desire.

How can I update single plot in multi plot xy graph?

Hi all,
I'm working on an HMI "front" for a larger acquisition/analysis system, that includes continuous performance monitoring of a turbine. The results of the measurements are stored arrays of contour lines, that represents turbine efficiency and guide vane openings. This analysis is all performed in the background. In the HMI, the performance data is loaded from file when the specific "report" is requested, and is plotted in an XY graph. I would like to indicate the current operation point of the machine by using a plot that is a single point. Thus, that point's position among the contour lines indicates the current performance of the turbine. This point is updated once every second, while the performance data remains the same for considerable amounts of time between recalculations (days to weeks).
Is there any way of updating the value of a single plot in a multiple plot XY Graph without having to redraw all the plots?
I've tried using the "Active Plot" property, which doesn't work.
My current solution is to keep all the data as input to the executing while loop and replace a subset of the plot array, but that of course requires the entire rewrite every time the operation point plot is updated.
Best regards,

Go to Solution.

You cannot redraw a single plot. If you want to update a single plot, you need to retain all plots in a shift regsiter and replace the data of the desired plot. However, your problem seems much simpler than that. To show a single point on a nearly static plot you have several options.
You can use a cursor that is controlled programmatically (the style can be a point, don't allow drag).
You can use annotations.
You can use the "plot images" feature that allows you to use image commands to draw anything on top of a graph.
None of these ideas require a redraw of any data.
I think the cursor idea is probably the easiest and most appropriate. Just use a property node with the following properties:
active cursor
cursor position x
cursor position y

Help needed in plotting Line Graph!!!!!!!!!Pls help!!

Hi, i need help in plotting a simple line graph showing the x&y axis and has to plot 3 different lines in the same graph.I have written a program and i need to implement this graph in it.Is there any tutorial for plotting line graphs,i mean steps included.
Please help!

You describe your need, but not where it originates from.
Is it a programming assignment? If so, I hope this is not your chosen major, as you will fail because you are a non-resourceful plagarist.
Do you need to simply graph some data? Use an existing package. There are free ones somewhere.
What do you mean "i have written a program and i need to implement this graph in it"? If you wrote the program, wouldn't you be done?

Including scaling information in binary file, which can be plotted in graph

I need to plot a graph from a from a bin file, I am able to plot the graph using read binary file vi but the scaling is nowhere close to what it needs to be.
Its in auto scaling mode, if I set the values manually by giving maximum and minimum values the graph disappears,
I believe it has something to do with some missing header file not included in the binary file as of now.
Can anyone help , I need to know , how to add header in the binary file so that I include the information of scales or units of measurements of the data which has to be plotted.

Hi Shrikant,
you include "header information" the same way as you include "data" in your binary file: You simply write that information to the file...
When trying to plot "the file" you read both parts (header and data), one after the other!

Iam using a table in numbers to plot daily graph lines. If I fill a cell with a text box at say zero it plots the graph. I can't actually set the cell value until the actual day but the graph plots it at zero when I don't want it to plot anything. Is tho

I am using a table in Numbers to plot daily graph lines. Mood swings of how I am on the day, i"m a depressive.
If I fill a cell with a step box at say zero it plots the graph. I can't actually set the cell value until the actual day but the graph plots it at zero when I don't want it to plot anything. Is there a work around. so thatbgraph only plots on the day?

The answer is (sort of) in your subject, but edited out of the problem statement in the body of your message.
When you use a stepper or a slider, the value in the cell is always numeric, and is always placed on the chart if that cell is included in the range graphed by the chart.
But if you use a pop-up menu cell, you can specify numeric or text values in the list of choices for in the menu. Numeric values will be shown on the chart. Text values will not.
For the example, the values list for the pop-up menu was:
5
3
1
Choose
-1
-3
-5
The first pop-up was set to display Choose, then the cell was filled down the rest of the column. Any text value (including a single space, if you want the cell to appear blank) may be used instead of Choose.
For charts with negative Y values, the X axis will not automatically appear at Y=0. If your value set will include negative values, I would suggest setting the Y axis maximum and minimum to the maximum and minimum values on your menu list, rather than letting Numbers decide what range to include on the chart. Place a line shape across the chart at the zero level, and choose to NOT show the X axis.

Problem With Plotting a graph

Hi,
I need help plotting a graph.
The situation is .... I have data of speed against time. Data is like this : a truck runs at some speed until 10 o clock. Now the driver changes time of the speed vs. time tracking device back to 9 o clock. Now if I plot this data it becomes a invalid graph as between 9 - 10 I will be having two values for the speed.
I thought of a solution that when ever a time change occurs I will drop the speed to 0 and again start plotting the graph with next point on the scale of x axis with the new set time ...... Is this possible ?
Please help.
Thanks and regards
Anirudh

Hi,
Here is a photo of what I want to do with the graph.
Here as the values that i am mappinng on x axis are repeated the graph is not one to one. Now to make it look like a one to one i want to drop it zero at the first 6. the restart the scale after 6 as 5 and continue mapping. Is this possible ?? ??
Thanks and Regards,

How do I add a vertical cursor to a 2-plot xy graph?

I have a 2-plot xy graph, and I would like to add a vertical cursor that can be dragged to any x position, and have the 2 y values displayed. How do I do this?

OK, my problem is deeper than reading cursor position. My cursor disappears when the VI is first run, never to appear again. I have the X-axis set up for absolute time, and I think that might have something to do with it.

How do I get the numbers ipad app to plot a graph of dates against values, where the most recent date is on the right of the graph, but the most recent date is at the top rather than bottom of the rows in the table?

How do I get the numbers ipad app to plot a graph of dates against values, where the most recent date is on the right of the graph, but the most recent date is at the top rather than bottom of the rows in the table?
Also how can it be a line graph without plotting a circle at each value?
Thanks this is very frustrating

Make a copy of the table and produce your Line chart or Bar chart from the copy. Sort the copy into the order you want to see in your chart.
Alternately you could use a Scatter Chart...

How to connect mysql database to labview and plot the graph

Hi all,
I am doing my final year project about labview. I need to connect my mysql workbench database to labview and plotting two sinwave in same graph. I can already connected my labview to mysql and showing the data in labview table.But I need to plot the two sinwave in on graph according to table data. Eg: table data&colon;      timestamp   wind speed wind direction
                                                                                                                                                                                                 2004-01-01        0.5                 56
                                                                                                                                                                                                  2004-01-01         0.6                 60
The attachemtn vi is about inserting file and plot the graph. And now I want plotting the sinwave using table data and the wind speed Y-axis,wind direction Y-axis in both side of my graph and the X-axis is showing the whole day timing like 00:00:00-24:00:00.  Can anybody combine these 2 vi to polting the graph according table data not according to file data.Thanks

Plotting a graph in real-time without reading from a file

Hello there.
I am trying to plot a graph. I have succeeded in plotting the graph by first writing the data to a text file (.TXT), then reading from that text file.
However, I feel this method will take up a lot of memory. Thus, I was wondering whether it is possible to plot the graph directly without first writing it to a text file.
Thanks a million.

You can use a while loop with a shift register, inside the while loop, put a case structure, and in it, your data aquisition vi. When you get data, use the shift register to append data to the array, using build array (the shift register will go in as an array, and data as an element) just execute the appending state when data is present, and you'll have a real time graph.
Hope this helps

Plotting two graphs in one single graph

Hi. This is my first time using control and simulation. I want to plot two graphs within a single graph. It seems that I have to use bundle and build arrays functions but I just do not know how to plot them. The x points and y points of (2) are just defined by a single set of points included in the array defined. The x points and y points of (1) are results of another formula, but both plots would fit in the same location of a single graph. I hope my question is understandable. I attach part of the model that I want to be plotted.
Thank you
