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 to plot bar graph in the real time?

Hi guys
I have n row and 3 column array, n will vary according the time, for example t=10ms, n=1;t=20ms, n=2;..., I would like to display all the data of the array in the bar graph in real time. I tryied with example "array to bar graph demo.vi" but very time, only one row was displayed.
Could anybody help me?
Many thanks.
Sorry I don't know how to capture the picture from VI, so I pasted it diagram to word document.

Where did you get this example. I can't find it listed in the current shipping examples.
Also, posting a small image of a section of a block diagram is not much to work with. You are using local variables and a sequence structure. Neither one is a good sign. If you would simply post the actual VI (and any subVIs), it would be much easier to see what you mean.

How to plot a graph from text file?

This is driving me nuts!
I would like to plot a list of numbers in a text file to a graph. Each munber is on a new line, like this -
345
356
378
379
345
etc.
I managed to import the file and split it with the 'Spreadsheet to array' function but can't get much further than that.
Help would be much appriciated.
Ben H

You just need to use the Read From Spreadsheet function and wire a 'True' to the transpose input. Wire the 1D array output to a graph.

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

How to Send Multiple Plot XY Graph from LabVIEW to Microsoft Excel

The link below describes exactly what I would like to do, however the link to the solution/work around does not work.
Has anyone got an alternative solution?

The standard Excel Insert Graph.vi cannot insert multiple XY Graphs to Microsoft Excel, so you will need to use the Report Generation Toolkit for Microsoft Office. You will find a link to an example program at the bottom of the page. I have also attached it below.

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,

Solved!
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

How can I save the plot on Graph control to disk like the plot on Picture.vi ?

Dear all
I have a question about saving the plot on graph control.
In Labview,there is two way to make a plot, using graph control (eg. waveform control ,wavechart control) and Picture.vi (eg. plot XY vi and plot waveform VI ) ,
but for Picture.VI there is some control for saving them to disk (eg. write jpeg file.vi or write bmp file.vi )
My question is that may I save the plot display in graph control to disk using some vi like saving Picture to disk.
I only know we only can right clicking and export implified image to save the plot on graphic plot?
What want is save the plot on graphic control without interface and save to disk directly?
many thanks!

RIght-click on your graph and select:
Create...Invoke Node and select method "export image". Wire the desired inputs and place it inside a case structure to be activated by e.g. a button.
