Graphing with logarithmic scale in AI5?

I received a graph in MS Excel that uses a logarithmic (as opposed to linear) scale, but as far as I know, it isn't possible to create a scatter-plot graph with logarithmic scale in Illustrator. Does anyone know if there is a plug-in or a script that can do this?
I am happy to upload the Excel file if that would be helpful. This is my first time using this forum, though, so I just need to know how to attach it.
Thanks

I found this link that has a plugin that states it does logarithmic scale, it is called ToolDemo here is the link, hope it's what you are looking for. http://www.telegraphics.com.au/sw/#tooldemo

Is it possible to express two y axes on a xy graph with different scale

Is it possible to express two y axes on a xy graph with different scale
I need to program it... Please help me

Hello.
Yes, it is possible to have two different vertical scales on an xy graph. There is no way that I know of to add a scale programmatically, but once you have added it, you can configure the range of it programmatically, as well as assigning a plot to any particular scale. You do this by using an xy-graph property node, with the properties YScale.Minimum, YScale.Minimum, and Plot.YScaleIndex respectively.

Problem with logarithmic scale in combination chart

Hi Experts,
I have a combination chart where in primary axis i am showing column chart and in the secondary axis, i am showing line chart. Now as the range of values used in the column chart is big, I have to use logarithmic scale in primary axis. But if i do so, the line chart is also being affected. The markers for negetive values in the line chart plotted in secondary axis disappears if I apply logarithmic scale in primary axis.
Is it a bug ?
I am using Xcelsius 2008 SP3.
Thanks and Regards

Hi:
Yes, I also noticed this problem, seems when you set primary axis as "Logarithmic", the secondary axis with negative value "<0" will be ignored as "0". I think it should be an issue.
A quick work around here is, swith your primary axis and your secondary axis, when you set seconary axis as "Logarithmic", the negative values in primary axis will not be ignored.
Hope it helps.

Line bar combo with logarithmic scale

hi, I found that
logarithmic scale is not supported for line bar combo.
I have checked the checkbox "Use logarithmic scale" under "Tick Marks & Scale Type" under "Axis Scaling" for the left axis.
but the charts (both checked and unchecked) are the same, there is no difference.
And it is unable to check the checkbox "Use logarithmic scale" for the right axis.
is it the limitation ?

Active Ingredient Management with Logarithmic Scale

Dear Gurus,
I would like to manage the batch specific concentration of an active ingredient that is measured on a log scale. This is similar to pH, but the active ingredient I would like to manage is a virus particle.
Any guidance would be appreciated,
MediSteve

Dear MediSteve
You could use the Characteristics
Characteristics are criteria according to which you can search for batches. These characteristics are defined when creating a class. There are two different types of characteristic:
User-defined characteristics :
These are characteristics which are not defined as fields in the batch master record.
For example: Active ingredient potency, viscosity, color, weight

Linking x-axis of two graphs (with seperate data types)

Hi all,
I am plotting a sine wave and a resulting waveform generated after driving a component with that sine wave.
I have 2 data types:
i) One is a waveform - of the sine wave
ii) The other is a cluster - resulting from two arrays (DBL)
Ideally I would like to display both of these on a single plot. But I can't seem to do that. If you know how to do this, then please let me know.
So, the next solution was to display them on a waveform chart and XY-plot, respectively.
Is there some way of linking the x axis, such that when I zoom into one plot, I simultaneously zoom into the other?
I hope my question is clear.
Thanks

If you are talking about the amplitude then it is the Y axis scale. Have a look here on how to add a second scale (http://forums.ni.com/ni/board/message?board.id=170&message.id=314415&query.id=105962#M314415).
Then you can have a separate scale for each plot. All plots on one graph with separate scales... you've got your cake and you can eat it too!

Working with dynamic scales in waveform graph - display problem

Hello
I want to use the same waveform graph in the frontpanel for different measurements. These measurements contains 1 to 8 curves, some of them I need to autoscale and others I want to use fixed scales. I wrote a method containing these functions and the functional behaviour is how I expected. But when it runs several times, LabView cannot correctly manage the graph display. Some scales are behind the graph or two scales are at the same position.
Perhaps you have a look at my example VI (LV 7.1), I generate a random Waveform and want to display a random number of curves and some of them in fixed, and some in autorange. The more I run the VI, the more the waveform graph display gets wrong. Does anybody know a solution?
Thank you very much for answering!

ScaleProblem.vi ‏165 KB

hi there
Ben, thanks for the link. Christian's suggestion is right and describes a similar problem.
I solved the problem now on an other way. Each time before I change the visability of the scales I reset all settings to the default (startup) values by property nodes (YScale.Maximum, YScale.Minimum, All Visible...). Then I make the scales which I don't need unvisible, link the graphs to the prefered scales and set the Min/Max or autoscale.
Important: I got 4 scales on each side. When I want to use eg 2 scales on the left, I need to make visible scale number 1 and 2. Scales 3 and 4 can then be set to unvisible (in other words in an incrementing order).
Makeing scales visible and unvisible is a little bit nervous on the screen. So, during that process I bring a picture of the last waveform on the top of my screen and change to the graph view when all settings are done.
Now I got a really great waveform viewer with the possibility, scaling some graphs by autoscale, others by fixed scales, using up to 8 scales selectable on the left/right side, user definied colors, names and units.
Thank you all for taking part of my problem.

Xy graph natural log scale

Hi,
How can I make a xy graph with a natural log scale on the y axis. I
know there is base 10 log, but is there something to produce a natural
log scale.
Thank you,
-Tim

All logs scales are similar so I am not quite sure what you mean by "natural log" scale.
Logarithmic mapping for an axis does not imply any special base, in fact the tick marks are labeled in direct original units (e.g. 0.1, 1, 10, 100) so there isn't even any conversion. Functions such as y=10^x, y=e^x, y=e^(-x), etc. will all shows as a straight lines once the mapping for the y axis is set to logarithmic..
Could you be a bit more specific on what you actually want?

Logarithmic scale in Charts - please clarify your prior answer

I have seen this CRVS2010 Beta2 - Logarithmic scales in Charts in the forum.
I don't think the question was clearly answered as I have a graph open in the 2008 Crystal Environment not Visual Studio and
I see Time Scale, Ordinal Scale and Numeric Scale.
My boss tells me that Logarithmic scale was in the older versions such a 8.5 .
What happened to it. Is is available and I just don't see it...??

Hello,
Moved your post to the Report Designer forum.
What that post indicated, because it was in the .NET SDK forum, is that to access the Chart Options is not available through our report engine. Nothing has changed, we've never been able to access those features in an application you write.
The Charting dll is supplied to us by a third party company called 3D Graphics. For what ever reason either 3D removed it or there were problems reported by us with it and it was removed.
If you want it back add your suggestion to the Idea Place, top right corner of this page, and if it gets enough votes PM's will look into it.
Thank you

XY Graph-Setting Y-Scale visible to False still Shows Corresponding Y scale Max and Min

Hi Guys,
I use XY graph to display the data with 3 Y-scales.
When I set any Y scale Visiblity property to False,its still display the Y scale Max and Min range Lines in plot area of the Graph and making cross line or extra parralel line with other visible scales.
Attached the screen shot for ref.
And I know the cross line may be due to different Y scales range setting.But XY graph should not display the invisible Y scales and its property as well.
please provide your suggestions to avoid that.
Solved!
Go to Solution.

The scales and the lines associated with those scales are separate properties. I have never tried it, and right now I am not at a computer, but there should be properties for setting the grid line colors. Set them to transparent.

Is there a function to have a graph with both the full signal and a zoomed in signal displayed?

See the Jpeg attached. Ive created this using 2 seperate graphs. Ideally Id like to do it using a single graph. Is this possible?

If you plot the same data as two seperate plots
AND
You create two seperate X and Y Scales
AND
You associate one plot with each scale pair of of XY scales.
Then you will be able to change the range of one set of scales to achieve an effect similar to zooming in on one.

Looking up the values in a waveform graph with a mouse click

Hi,
Does anyone know how to look up the values in a waveform graph with a mouse
click but... without the cursor legend on, if i press in the waveform graph
nothing happens, i must search my cursors and only then i can see the values
of my signal data?! Isn't there any other way?
Best regards,
Thijs Boerée

Dear Chad,
I know of the function "bring cursor to center". I also figured out that
when i use a property node of the cursor array of clusters, that i can see
that some values change when i move the cursor (i can see the X and Y scale
value change of the graph and also the values of the mouse pointer (in
points due to screen resolution)) But in this cluster i can't set the mouse
position. I allready made a VI where i can see the bounds of my
waveformgraph and I have the Xscale (min and max) and the Yscale (min and
max), with a linear fit i can translate my mouse position to X an Y scale
values and when i click on my waveform graph the cursor go's to that
position (property node of the cursor position), only disadvantage is that i
only have the bounds of my plot area and not the position, i do have the
position of my waveform graph but the plot area isn't allways in the center,
if i could extract the position of the plot area i may find a solution to
solve this problem.
And to file a product question:
I would like to see the function that with a mouse click a little menu
appears and that there are options to for example set a marker on that data
and when you right click on it, that there are options to remove it or to
add comment, a 2D array could make a list of the different channels with
it's markers (time stamps and comments).
Best regards,
And thank you for your help.

XY graph with N axes and translate it into a picture

Hello - The VI has two windows diagrams (lower, narrow) is possible to unite them in one picture? - The VI (top left window graphics) have a common axis, but its hard to see the first graph "PLOT0" because he has little value compared with the values of graphics "PLOT1", to avoid this problem, adding even more axis "X and Y '(top right graph window), now both graphs are visible, but they overlap each other, how to spread these graphs relative to each other. (In the diagram where one axis is obtained by adding a factor to make a Slider and Slider1), and the graph with 2 separate axes do not get how to be? - Is it possible to programmatically make up the axes of the "Duplicate Scale"? Thank you.

now both graphs are visible, but they overlap each other, how to spread these graphs relative to each other.
You can move the secondary axes to the other side of the graph by right clicking on it and selecting "Swap Sides."
Is it possible to programmatically make up the axes of the "Duplicate Scale"?
I don't understand this question. Do you want to programmatically set the Max and Min of the axis? Please clarify the question.

Autoscale XY Graph with 2 plots

I have a graph with 2 different plots on the same Y axis. If I turn off the "visible" property on one of these plots (so I have only one plot visible), the autoscale Y continue to take both plots into account, thus creating a very too large scale for the visible plot. Is there a way to autoscale only one plot while another is hidden but associated with the same scale?

You have several possibilities, for example:
* instead of setting the property to invisible, temporarily replace one graph with empty data. (see attached sample code).
* Don't use autoscale, but use ArrayMinMax on the visible y values, the set the yrange.minimum and yrange.maximum accordingly.
*switch the second plot to a second y scale while invisible and back to scale 1 when visible again.
* any other variation of the above.
