How to plot semi log graph?

I am dealing with circuit in which resistance is automatically varying(IC AD633).I want to plot graph of Voltage against this variable resistance.Also as the  range of variation is very large I want to use semi log graph.Is it possible in Multisim? Please reply as soon as possible.

Hello,
In the Grapher View you can configure scale, range, etc. Double-click the Grapher View area to open its Properties. There, you can configure the Left/Right axis and the Top/Bottom axis. For example, you can select a Linear scale for the bottom axis and a Logarithmic scale for the left axis to create a semi-log graph.

  • Straight line on semi-log graph

    hi, I'm trying to graph an array of 500 points on a semi-log graph. The line look right on the Linear Scale but it curves a little bit when I changed to Logarithmic scale. How can I make it a straight line on the logarithmic scale? please see attachment

    There's nothing you can do short of changing the data--or the scaling of the x axis. What you're seeing is an effect of the y-axis scaling.

  • Plotting on Log graph

    Good Day,
    I am plotting a semilog graph displayed on the front panel of my program.
    The unit on the x-axis is in frequency(Hz) and the y-axis is in dBc/Hz
    I wanted to program in such a way that the a straight line is plot between points at 10,100,1K,10K and 100KHz.That is to say I only need to key in 5 values.
    My plot now jumps back to zero as all the values set to zero by default when i do not enter value into each array cell. I hope someone out there has solution to this.
    Thank you.
    Regards,
    Daniel

    You probably want to use an xy-graph. This way you can graph arbitrarily spaced points.
    (If you want to use a waveform graph, you must generate interpolated values for all intermediary array elements).

  • How to let the user define the colors for each plots in the graph (I use LabVIEW 7)?

    How to let the user define the colors for each plots in the graph (I
    use LabVIEW 7)?

    Hi,
    Take a look at this example, it uses property nodes to select tha
    active plot and then changes the color of that plot.
    If you want to make the number of plots dynamic you could use a for
    loop and an array of color boxes.
    I hope this helps.

  • How can I get my graph to plot vs. my data points instead of vs. time?

    how can I get my graph to plot vs. my data points instead of vs. time?

    Maybe you could exaplin in a few more words what "my data" is. Are the values equally or randomly spaced?
    If they are equally spaced, just adjust offset and multiplier, and axis label.
    If they are randomly spaced you are probably looking for an X-Y graph. Check the shipping examples.

  • 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 build query to give daily balance across bank accounts? (to then plot in a graph)

    How would one build a query to give daily balance across bank accounts? (to then plot in a graph)
    Assumptions:
    * There is a table TRANSACTIONS which includes columns TRANS_DATE, AMOUNT and BANK_ID. It does NOT include a column for balance. So current balance for a bank account is the sum of the AMOUNTs for that BANK_ID for example. Balance on date XX will be the sum
    of all AMOUNTS for that BANK_ID for all TRANS_DATE's prior and including the date XX.
    * There is not necessarily transactions on every day for each bank
    * Table BANKS which has BANK_ID and TITLE
    Would like a query that gives: Supply StartDate and EndDate for the query:
    Date Bank1Balance Bank2Balance Bank3Balance TotalBalance
    1/1/15 $100 $200 $100 $400
    1/2/15 $200 $200 $100 $500
    etc

    You'll find examples of queries for computing balances in various contexts in Balances.zip in my public databases folder at:
    https://onedrive.live.com/?cid=44CC60D7FEA42912&id=44CC60D7FEA42912!169
    If you have difficulty opening the link copy its text (NB, not the link location) and paste it into your browser's address bar.
    The queries in this little demo file return balances per transaction, however, whereas you appear to wish to return balances at close of business per day.  This can easily be done by means of a subquery which sums all transactions to date.  To return
    balances for all dates regardless of whether or not any transactions have been undertaken on the day, an auxiliary calendar table can be introduced into the database to plug the gaps,  The Calendar.zip file in my same OneDrive folder has means of generating
    such a table.
    With the introduction of an auxiliary calendar table into the database a query can then be written to return the balance per customer at close of business per day over the period 2009 - 2012 covered by the data in the Transactions table:
    SELECT CustomerID, Firstname, LastName, calDate,
       (SELECT SUM(TransactionAmount)
         FROM Transactions
         WHERE Transactions.CustomerID = Customers.CustomerID
         AND Transactions.TransactionDate <= Calendar.calDate) AS Balance
    FROM Calendar,Customers
    WHERE calDate BETWEEN #2009-01-01# AND #2012-12-31#
    ORDER BY CustomerID, CalDate;
    Rows for each customer/date are returned by means of the Cartesian product of the Calendar and Customers tables (the latter analogous to your Banks table), and the subquery returns the balance at close of each day by correlating the Transactions table with
    the Customers and Calendar tables, returning the sum of all transactions per customer up to and including the date in question.  In this example credit and debit transactions are expressed as positive and negative values in a single column of course,
    but where separate credit and debit columns are used its merely a case of summing (Credit-Debit), as done in some of the examples in my demo.
    To return the data in a horizontal format per date I'd suggest the use of a report which returns one row per date, and within it a multi-column subreport in across-then down column layout, linking the subreport to the parent report on the date columns.

  • Labeling Variable Number of Plots on a Graph?

    I'm loading up an unknown number of files and graphing them. Since it can get a bit confusing, I'd like to be able to take a portion of the file name and label each plot on my graph. Since there is a variable number of graphs, I can't seem to work around how to wire the property node. There are several other things I'd like to do with the graph, but dont know if its possible or not such as having a label pop up if your cursor is over a plot.

    You are going to have to embed the reference node for the graph into a for-loop like the attached example. File names or portions thereof are built as strings and then added into the property node Plot>>Plot Name.
    I'm not sure about how to get a label to pop up if you are over the plot. You might be able to do it with some cursors and associated code.

  • Problem Plotting a Line Graph

    I am trying to plot some line graphs on Numbers and am a new user.
    I can't seem to work out an issue. I want the numbers on the X axis to ascend from 0 onwards from left to right but at the moment they are descending from 10 to 0 left to right.
    How can I change this so the graph is plotted logically?
    Thanks in advance

    There are two basic types of X-Y charts.  All but one are "category" charts where the X axis is evenly spaced and the "numbers" are actually text. The data will be presented in the order listed in your table.  The other is a scatter chart. The icon for this chart looks like a shotgun blast.
    If your X axis numbers are evenly spaced (0,1,2,3...) you can use either type of chart.  Sort your table in ascending order and it will chart as you want it to.
    If your X axis numbers are not evenly spaced (such as 1,2,4,5,10) and you want the chart to be a true X-Y plot of the data, you have to use the scatter chart.  In contrast to the category charts where the X axis values must be in a header column/row, a scatter chart requires the X and Y data to be in data cells. You may have to move your data over a column so the X data is not in a header column.

  • How to plot y=mx+c

    Hi,
    I'm trying to complete a line of best fit generator for a university assignment.
    I realise LabView already has the ability to plot it for me, but my assignment requires me to do it myself with my own code.
    The problem I am stuck on right now is how to plot a straight line on a graph; given y, m and x.
    I have a graph, and I have the code to calculate the y, m and x of my line, but I cant understand how to plot this line on my graph.
    I'm sorry this is such a mundane problem, but I've been looking for days now and I still can't find how, and I must be thinking about it entirely the wrong way.
    Attached is a quick screenshot and my VI if it helps. Also attached is a portion of the document I'm following that my professor made to help me.
    Thank you in advance, you clever people

    The main problem is that your document is wrong. The sums actually need to be taken from i=0 to i=N-1 (The document says i=1 to i=N-1, which is incorrect).
    You need to make the VI scalable, so the code works no matter how many points there are in the input arrays. You don't want to write different subVIs for each array size, right? Also remember that "index array" is resizable, so would only need one instance to get all elements.
    As Tim said, you can get N for each array by using "array size" (you might even include error handling and return an error if the X and Y arrays are of different size or if both are size=0, for example.). The rest of the code can be done by operating directly on arrays.
    Yes, as you pointed out, there is a linear fit built into LabVIEW. I would still place it on the diagram, just to see if your own code returns about the same results. Two opinions are better than one! (most likely they will not be identical to the last bit, but that is to be expected).
    Before saving an example VI, you should fill the values from the document into the x and y arrays and make the values the default so you don't need to enter anything next time you work on the VI.
    And, yes follow your advisors suggestion and build the code into a subVI. I would recommend to use the same connector pattern as the built-in linear fit subVI, just leave out the stuff that you don't use.
    Here's one possibility how the flat code (not subVI yet) would look like. Study it in detail and make sure you understand every single part of it, then do your own. Good luck!
